Without a checkpointer, LangGraph discards conversation state between invocations, even when the same `context_id`/`thread_id` is used. + +**Fix needed:** Add `MemorySaver` (single-pod) or `AsyncPostgresSaver` (multi-pod) to `SandboxAgentExecutor.__init__` and pass it to `build_graph()`. + +**Quick fix (MemorySaver):** +```python +# In SandboxAgentExecutor.__init__(): +from langgraph.checkpoint.memory import MemorySaver +self._checkpointer = MemorySaver() + +# In execute(), pass to build_graph: +graph = build_graph( + workspace_path=workspace_path, + permission_checker=self._permission_checker, + sources_config=self._sources_config, + checkpointer=self._checkpointer, # ADD THIS +) +``` + +Note: The graph must NOT be rebuilt on every request when using a checkpointer — or use a shared checkpointer instance across calls. Currently `build_graph` is called per-request in `execute()`. Either cache the graph or extract the checkpointer to be shared. + +**Better fix:** Build the graph once in `__init__` with a checkpointer, reuse it across requests: +```python +class SandboxAgentExecutor(AgentExecutor): + def __init__(self): + ... + self._checkpointer = MemorySaver() + # Build graph once, reuse across requests + self._graph = build_graph( + workspace_path=config.workspace_root, + permission_checker=self._permission_checker, + sources_config=self._sources_config, + checkpointer=self._checkpointer, + ) +``` + +But this means workspace_path is fixed at init time, not per-context. The workspace_path is used by the file tools, so they'd need to be context-aware. This needs a small refactor: either make the tools resolve workspace_path at call time from the state, or build the graph per-context but share the checkpointer. + +**Recommended approach:** Share the checkpointer, build graph per-context (current pattern), just pass the shared checkpointer: +```python +class SandboxAgentExecutor(AgentExecutor): + def __init__(self): + ... + self._checkpointer = MemorySaver() + + async def execute(self, context, event_queue): + ... + graph = build_graph( + workspace_path=workspace_path, + ... + checkpointer=self._checkpointer, # Shared across calls + ) + # thread_id config already set: + graph_config = {"configurable": {"thread_id": context_id}} +``` + +### E2E Test to Add + +```python +@pytest.mark.asyncio +async def test_multi_turn_memory(self, test_session_id): + """Verify agent remembers context across turns.""" + agent_url = os.getenv("SANDBOX_AGENT_URL", "...") + client, _ = await _connect_to_agent(agent_url) + context_id = f"memory-{test_session_id}" + + # Turn 1: Tell the agent a name + msg1 = A2AMessage( + role="user", + parts=[TextPart(text="My name is Bob Beep")], + messageId=uuid4().hex, + contextId=context_id, + ) + response1, _ = await _extract_response(client, msg1) + assert response1, "Turn 1: No response" + + # Turn 2: Ask for the name back + msg2 = A2AMessage( + role="user", + parts=[TextPart(text="What is my name?")], + messageId=uuid4().hex, + contextId=context_id, + ) + response2, _ = await _extract_response(client, msg2) + assert "Bob Beep" in response2, ( + f"Agent didn't remember the name.\n" + f"Expected 'Bob Beep' in response.\n" + f"Response: {response2}" + ) +``` + +## Cluster & Environment + +| Item | Value | +|------|-------| +| Cluster | `kagenti-hypershift-custom-lpvc` | +| Kubeconfig | `~/clusters/hcp/kagenti-hypershift-custom-lpvc/auth/kubeconfig` | +| Agent namespace | `team1` | +| Agent deployment | `sandbox-agent` | +| Agent service | `sandbox-agent:8080` (maps to container 8000) | +| LLM | OpenAI `gpt-4o-mini` via `openai-secret` in team1 | +| Image registry | `image-registry.openshift-image-registry.svc:5000/team1/sandbox-agent:v0.0.1` | +| Worktree | `.worktrees/agent-examples` on branch `feat/sandbox-agent` | + +### Key Commands + +```bash +# Source env +export MANAGED_BY_TAG=${MANAGED_BY_TAG:-kagenti-hypershift-custom} +source .env.${MANAGED_BY_TAG} +export KUBECONFIG=~/clusters/hcp/${MANAGED_BY_TAG}-lpvc/auth/kubeconfig + +# Check agent +kubectl get pods -n team1 -l app.kubernetes.io/name=sandbox-agent +kubectl logs -n team1 deployment/sandbox-agent --tail=20 + +# Rebuild after code changes +cd .worktrees/agent-examples +git add -A && git commit -s -m "fix: ..." && git push origin feat/sandbox-agent +# Back to main repo: +KUBECONFIG=~/clusters/hcp/kagenti-hypershift-custom-lpvc/auth/kubeconfig \ + kubectl create -f - < **Date:** 2026-02-23 (updated 2026-02-25) | **Clusters:** `kagenti-hypershift-custom-lpvc`, `kagenti-team-sbox` (2 workers each, v1.33.6) | **Worktree:** `.worktrees/sandbox-agent` (branch `feat/sandbox-agent`) + +## Executive Summary + +This document synthesizes research across 7 open-source projects, the Kubernetes SIG agent-sandbox roadmap, the broader sandboxing landscape, and Kagenti's own prototype work to answer a concrete question: **how do we run a repo that has `CLAUDE.md` and `.claude/skills/` — the same repo an engineer operates locally with Claude Code — inside a Kubernetes-hosted sandbox with any LLM plugged in, reusing the exact same skills, under zero-trust identity and token exchange?** + +The answer is a layered architecture combining: +1. **Container/microVM isolation** (gVisor, Kata, or Firecracker via kubernetes-sigs/agent-sandbox) +2. **Kernel-enforced capability restriction** (Landlock/Seatbelt via nono) +3. **Credential isolation and network filtering** (Squid proxy per paude, credential scoping per devaipod/service-gator) +4. **Git-as-trust-boundary workspace sync** (per devaipod, ai-shell, paude) +5. **Token exchange via SPIFFE/Keycloak** (Kagenti's existing SPIRE + Keycloak stack) +6. **Skills/CLAUDE.md mounted as the agent's instruction set** (repo cloned at sandbox init time) + +--- + +## Table of Contents + +1.

Skills encode **repeatable workflows** — guided procedures that any engineer (or agent) can follow. Together, they are the operating manual for the repository. + +Today, an engineer runs `claude` in this repo locally. Claude Code reads `CLAUDE.md`, loads skills, and operates the codebase with full context. The question is: **how do we take this exact same setup and run it in a Kubernetes sandbox — both interactively (engineer-driven) and autonomously (agent-driven)?** + +### Mode 1: Engineer-Driven (Claude Code in Sandbox) + +The engineer wants to use Claude Code but in a sandboxed environment — either because the work involves untrusted code, because they want stronger isolation than their laptop provides, or because the codebase requires access to cluster-internal resources. + +``` +Engineer → Kagenti UI / CLI + │ + ├── "Create sandbox for github.com/myorg/my-project" + │ + ▼ +Sandbox Pod (gVisor isolation) + ├── Init: git clone → /workspace + ├── Claude Code (or any coding agent) + │ ├── Reads /workspace/CLAUDE.md → system prompt + │ ├── Reads /workspace/.claude/skills/ → available workflows + │ ├── Shell tools: grep, sed, git, python, pip (permission-controlled) + │ └── Network: filtered via proxy (LLM API + pypi + GitHub API only) + ├── Identity: SPIFFE SVID (zero-trust, no static tokens) + └── Storage: PVC (persists across sessions) +``` + +The engineer attaches to the sandbox via SSH, web terminal, or IDE remote — similar to how [devaipod](https://github.com/cgwalters/devaipod) and [ai-shell](https://github.com/arewm/ai-shell) work locally, but Kubernetes-hosted. Changes stay in the sandbox until the engineer explicitly pulls them via git. + +### Mode 2: Autonomous Agent (Cron, Alert, Webhook) + +The same repo, same CLAUDE.md, same skills — but now triggered without a human in the loop: + +``` +Trigger (cron / alert / webhook / A2A message) + │ + ├── "Run skill tdd:kind on PR #42" + │ or "Run skill k8s:health on cluster lpvc" + │ or "Fix failing CI on branch feature/x" + │ + ▼ +Sandbox Pod (gVisor isolation) + ├── Init: git clone → /workspace (+ checkout PR branch) + ├── Agent (any LLM via litellm) + │ ├── Reads /workspace/CLAUDE.md → system prompt + │ ├── Reads /workspace/.claude/skills/ → available workflows + │ ├── Executes the requested skill autonomously + │ ├── Shell tools: permission-controlled (settings.json) + │ └── Network: filtered (proxy sidecar, allowlist only) + ├── Identity: SPIFFE SVID → Keycloak token exchange → scoped GitHub access + ├── Results: git commit + push draft PR, or A2A response, or alert update + └── Lifecycle: auto-delete after completion (or TTL) +``` + +**Autonomous trigger examples:** + +- **Nightly CI health check:** + A cron fires at 2 AM. The agent runs `/rca:ci` against main — analyzes recent CI failures, identifies flaky tests and broken pipelines. If it finds issues, it runs `/tdd:ci` to write fixes, then pushes a draft PR with the diagnosis and proposed changes. The team reviews the PR in the morning. + +- **Implement a GitHub Issue:** + Someone comments `/agent implement` on Issue #234 ("Add retry logic to the API client"). The agent spawns a sandbox, clones the repo, reads the issue description, and starts working. It asks a clarifying question in the issue thread ("Should retries use exponential backoff or fixed intervals?"). The engineer replies in the issue comment. The agent reads the reply, continues, and opens a draft PR linking to #234. The conversation continues in both the issue and Slack as the engineer reviews. + +- **Incident response:** + PagerDuty fires an alert for pod crashloops in production. The agent spawns a sandbox with the cluster kubeconfig, runs `/k8s:health` and `/k8s:logs` skills, identifies the root cause (OOM on the new deployment), and posts a diagnosis to the PagerDuty incident timeline. If confident, it also prepares a resource limit fix as a draft PR. + +- **PR CI failure assistance:** + A PR's CI checks fail. GitHub sends a `check_suite` webhook. The agent spawns a sandbox, checks out the PR branch, and runs `/rca:ci` against the failed job logs. It identifies the issue — a new dependency broke an import path — and pushes a fix commit directly to the PR branch. If the fix requires a design choice (e.g., "pin to v2.3 or upgrade the caller?"), it comments on the PR asking the author. The author replies in the PR thread, the agent reads the reply, applies the chosen approach, and pushes again. CI goes green. + +- **Addressing PR review feedback:** + A reviewer leaves comments on PR #87: "This needs unit tests for the error paths" and "The retry logic should be tested against a real cluster, not just mocks." The engineer comments `/agent address-reviews`. The agent spawns a sandbox, reads all pending review comments via GitHub API (scoped token), and plans the work: it runs `/tdd:ci` to add unit tests for the error paths (local, fast), then runs `/tdd:hypershift` against the live HyperShift cluster to add an E2E test for the retry logic under real conditions. It pushes the new tests as a commit to the PR branch and replies to each review comment with what it did: "Added `test_retry_on_connection_error` and `test_retry_exhaustion` — see commit abc123" and "Added E2E test `test_retry_against_live_cluster` on HyperShift — see commit def456, CI running." The reviewer gets notified, reviews the new tests, and resolves the threads. + +- **Agent-to-agent delegation:** + A planning agent working on a feature request determines it needs test coverage. It sends an A2A message to spawn a sandbox agent with the task "Write E2E tests for the new /users endpoint following the patterns in tests/e2e/". The sandbox agent works independently, pushes results, and reports back to the planning agent. + +### Why This Matters + +| Property | Engineer-Driven | Autonomous Agent | +|----------|----------------|------------------| +| **Same skills/CLAUDE.md** | Yes | Yes | +| **Same isolation** | Yes | Yes | +| **Same identity model** | SPIFFE SVID | SPIFFE SVID | +| **Human in loop** | Always (interactive) | Optional (HITL for risky ops) | +| **LLM pluggable** | Claude Code (default) | Any model via litellm | +| **Lifecycle** | Long-running, persistent | Ephemeral or TTL-based | +| **Git trust boundary** | Engineer pulls changes | Agent pushes draft PR | + +The key insight: **skills and CLAUDE.md are the portable instruction set**.

The Sandbox CRD provides a declarative API for this: create a Sandbox, get a locked-down pod with stable DNS, automatic expiry, and warm-pool pre-provisioning. + +**How it works:** The CRD family includes four resources. **SandboxTemplate** defines the pod shape (image, RuntimeClass, resource limits, security context). **Sandbox** is a running instance — a singleton pod (replicas: 0 or 1) with a headless Service for stable DNS (`sandbox-name.namespace.svc.cluster.local`). **SandboxWarmPool** maintains pre-created Sandbox instances in a suspended state so that claiming one is sub-second. **SandboxClaim** is the request object — a controller creates a claim, the warm-pool binds it to an available Sandbox, and the pod transitions to running. Lifecycle is governed by `shutdownTime` (absolute UTC expiry) and `shutdownPolicy` (`Delete` or `Retain` for forensics). + +**What we use:** [kubernetes-sigs/agent-sandbox](https://github.com/kubernetes-sigs/agent-sandbox) — deploy controller directly. + +**Note on observability:** The agent-sandbox controller has its own OTEL tracing (`--enable-tracing`) for **lifecycle events** (pod creation, scheduling, shutdown) — but this is infrastructure-level, not agent-level. It does NOT create MLflow-compatible root spans, parse A2A bodies, or set GenAI semantic conventions. That remains AuthBridge's responsibility (C13). The two are complementary: agent-sandbox traces the pod lifecycle, AuthBridge traces the agent invocation. + +**Relationship to other capabilities:** C2 (RuntimeClass in template), C13 (AuthBridge handles agent-level OTEL, agent-sandbox handles lifecycle OTEL), C16 (hardening in template), C17 (SandboxClaim is the trigger mechanism). + +--- + +### C2: Runtime Isolation + +Even with a correctly configured pod, a kernel exploit in the shared host kernel can escape any container. Runtime isolation interposes an additional kernel boundary — either a user-space syscall filter (gVisor) or a lightweight VM (Kata) — so that a compromised agent never touches the real host kernel. + +**How it works:** A Kubernetes `RuntimeClass` resource is created for each backend. **gVisor** intercepts syscalls in user space, imposing 10-30% I/O overhead but adding negligible startup latency and supporting high pod density. **Kata Containers** boots a minimal guest kernel per pod, providing near-native CPU at the cost of 100-500ms boot time. The choice is workload-dependent: gVisor for most agent tasks, Kata when running untrusted native binaries. + +**What we use:** [gVisor](https://gvisor.dev/) (default) and [Kata Containers](https://katacontainers.io/) (option), via standard Kubernetes RuntimeClass. + +**Implementation status (Feb 2026): ⏸️ Deferred.** gVisor (`runsc`) rejects ALL SELinux labels, but CRI-O on RHCOS always applies SELinux labels to containers. This makes gVisor incompatible with OpenShift's default security model. A wrapper script approach was prototyped (strips SELinux from OCI spec before calling `runsc`) but requires node rollout to test. A custom SCC (`gvisor-sandbox`, priority 20) was created to bypass SELinux for sandbox-agent service accounts. + +**Security comparison without gVisor:** + +| Layer | gVisor (ideal) | runc + hardening (current) | Delta | +|-------|---------------|--------------------------|-------| +| Kernel isolation | User-space kernel (syscall interception) | Shared host kernel | gVisor is stronger | +| Filesystem | gVisor's internal VFS | nono Landlock ABI v5 (irreversible) | Comparable — Landlock is kernel-enforced | +| Capabilities | All dropped by gVisor | All dropped via SecurityContext | Equivalent | +| SELinux | Incompatible (rejected) | Enforced via restricted-v2 SCC | runc is actually stronger here | +| seccomp | gVisor has own syscall table | RuntimeDefault profile | gVisor is more restrictive | +| Network | gVisor's netstack | NetworkPolicy + Squid proxy + AuthBridge | Comparable at L3/L4/L7 | +| Overall | Stronger kernel boundary | Adequate with defense-in-depth (4 layers) | Acceptable for current threat model | + +**Decision:** The current runc + SecurityContext hardening (C16) + nono Landlock (C3) + Squid proxy (C5) + NetworkPolicy provides 4 layers of isolation. While gVisor adds a stronger kernel boundary, the current stack is adequate for the threat model (LLM-generated code execution with network filtering). Kata Containers is the path forward for workloads requiring VM-level isolation — it does not have the SELinux incompatibility. + +**Relationship to other capabilities:** C1 (RuntimeClass is a field in SandboxTemplate), C3 (nono provides defense-in-depth inside the container — even if gVisor is bypassed, nono's Landlock still restricts filesystem and network). + +--- + +### C3: In-Container Kernel Sandbox (nono) + +Runtime isolation (C2) protects the host from the container. But the agent process still has broad access *within* its own container. nono locks down the process from the inside, using OS-level mandatory access controls that are **irreversible once applied** — no API can loosen them, in direct contrast to OpenClaw's CVE-2026-25253 where the sandbox was disabled via a tool call. + +**How it works:** On Linux, nono uses **Landlock LSM** for filesystem restrictions and **seccomp-BPF** for syscall filtering. Policies are built with a **CapabilitySet builder**: the launcher specifies which paths are readable/writable, whether network is allowed, and which executables may run. A hardcoded **never-grant blocklist** ensures `~/.ssh`, `~/.kube`, `~/.aws`, `/etc/shadow` are always denied. For runtime capability expansion, a **supervisor process** can inject pre-opened file descriptors into the sandboxed process without relaxing the Landlock policy itself. Python bindings via PyO3 let the Kagenti agent launcher call `nono.sandbox()` directly. + +**What we use:** [nono](https://github.com/always-further/nono) — Python bindings via PyO3. + +**Relationship to other capabilities:** C2 (nono is layered on top of gVisor/Kata — they protect the host, nono protects the container's filesystem from the agent), C7 (the application-level permission model is a third layer above nono's OS-level enforcement). + +--- + +### C4: Instruction File Attestation + +Agents load instructions from `CLAUDE.md` and `.claude/skills/`. If an attacker modifies these files, the agent executes poisoned instructions with full tool access. Attestation verifies instruction files against a known-good signature before the agent reads them — preventing supply chain attacks like OpenClaw's ClawHavoc skill poisoning. + +**How it works:** Before loading any instruction file, the launcher computes a **SHA-256 digest** and verifies it against a **Sigstore bundle** (DSSE envelope signed with an OIDC-linked identity). Three enforcement modes: `Deny` (hard block), `Warn` (log + allow), `Audit` (silent record). We **replicate the concept** from nono's trust module rather than adopting it directly — Kagenti has its own signing pipeline tied to Keycloak OIDC identities. + +**What we use:** [sigstore-python](https://github.com/sigstore/sigstore-python) for verification, integrated into the Kagenti agent launcher. Concept from [nono trust module](https://github.com/always-further/nono/tree/main/crates/nono/src/trust). + +**Relationship to other capabilities:** C10 (skills loading depends on attestation passing), C15 (TOFU is a simpler alternative for dev environments where Sigstore infrastructure is unavailable). + +--- + +### C5: Network Filtering + +A compromised agent could exfiltrate data to arbitrary endpoints or connect to internal services it shouldn't access. Network filtering enforces a domain-level allowlist so the agent can only reach explicitly approved destinations. + +**How it works:** A **Squid forward-proxy sidecar** runs in the pod. The agent's `HTTP_PROXY`/`HTTPS_PROXY` point to `localhost:3128`. Squid's config: `acl allowed_domains dstdomain .api.openai.com .pypi.org .api.github.com` → `http_access allow allowed_domains` → `http_access deny all`. Any request to an unlisted domain gets HTTP 403. HTTPS uses `CONNECT` tunneling (Squid checks the domain but doesn't terminate TLS). Works alongside Istio Ambient mTLS and Kubernetes NetworkPolicy. + +**What we use:** [Squid](http://www.squid-cache.org/) as sidecar, following the [paude](https://github.com/bbrowning/paude/blob/main/containers/proxy/squid.conf) pattern. + +**Relationship to other capabilities:** C6 (Squid controls *where* the agent connects; AuthBridge controls *with what identity* — complementary, not overlapping), C16 (NetworkPolicy is L3/L4 backstop beneath Squid's L7 domain filtering). + +--- + +### C6: Credential Isolation (AuthBridge) + +The most dangerous thing a compromised sandbox can leak is a long-lived credential. If the agent never possesses raw credentials, a sandbox escape yields nothing reusable. AuthBridge ensures agents authenticate using their workload identity, never raw secrets. + +**How it works:** AuthBridge is an **Envoy ext_proc** in the Istio mesh. When an agent makes an outbound request, ext_proc intercepts it and performs a **token exchange**: presents the pod's **SPIFFE SVID** to Keycloak, which returns a **scoped OAuth2 token** (e.g., GitHub App installation token limited to specific repos/permissions). The token is injected as the `Authorization` header. The agent code never sees the token. If the sandbox is compromised, the attacker gets only the SVID (short-lived, scoped, useless outside the SPIRE trust domain). + +**What we use:** [AuthBridge](https://github.com/kagenti/kagenti-extensions/tree/main/AuthBridge) — already built. Uses Envoy ext_proc, SPIRE for SVID, Keycloak for token exchange. + +**Relationship to other capabilities:** C5 (Squid filters *where*, AuthBridge controls *as whom*), C12 (AuthBridge IS the token exchange — same component), C3 (nono blocks filesystem access to credential files, complementing AuthBridge's network-level isolation). + +--- + +### C7: Permission Model (settings.json) + +Without a permission model, every agent action either requires human approval (too slow) or runs unchecked (too dangerous). The three-tier policy balances autonomy with safety. + +**How it works:** `settings.json` defines `allow`, `deny`, and `ask` lists with glob patterns like `shell(grep:*)` or `shell(sudo:*)`. At runtime: deny checked first (always wins), then allow (auto-approved), then HITL for anything unmatched. HITL triggers LangGraph `interrupt()` which pauses execution until a human responds. + +**What we use:** Custom policy engine in sandbox agent + LangGraph interrupt. Already built. + +**Relationship to other capabilities:** C3 (nono is kernel-level enforcement, settings.json is application-level — defense in depth), C14 (HITL is the escalation when settings.json says neither allow nor deny), C8 (sources.json complements with resource limits). + +--- + +### C8: Capability Declaration (sources.json) + +Even when an operation is permitted, the agent needs boundaries on *what resources* it can touch. An agent allowed to `pip install` shouldn't install arbitrary packages from untrusted registries. + +**How it works:** `sources.json` is baked into the agent image (immutable at runtime). It declares: package managers (enabled/disabled, blocked packages, registries), web access (domain allowlist), git (allowed remotes, max clone size), and runtime (languages, execution time limits, memory ceiling). The agent checks this before executing any tool. + +**What we use:** Custom JSON schema, enforced by sandbox agent runtime. Already built. + +**Relationship to other capabilities:** C7 controls *what operations*, C8 controls *what resources* — complementary. The domain allowlist in C8 is enforced at network level by C5 (egress proxy), providing defense-in-depth. + +--- + +### C9: Git Workspace Sync (Primary + Dynamic Multi-Repo) + +Agents need source code access but shouldn't have direct write access to shared repositories. Git workspace sync provides a two-tier approach: the primary repo is cloned at init (for skills/config), and additional repos are cloned live by the agent as needed. + +**How it works:** + +*Primary repo (init container):* An init container clones the **primary repo** — the one containing `CLAUDE.md`, `.claude/skills/`, `settings.json`, and `sources.json` — into `/workspace` on a PVC. This must happen before the agent starts because the skills and permissions define the agent's operating instructions. + +*Additional repos (runtime, dynamic):* During execution, the agent can clone additional repos via `shell(git clone:*)` into `/workspace/repos/`. This is controlled by `sources.json` `allowed_remotes` — only repos matching the allowlist patterns (e.g., `https://github.com/kagenti/*`) can be cloned. All git operations are authenticated transparently by AuthBridge (C6): the agent runs `git clone https://github.com/kagenti/extensions` and AuthBridge injects the scoped GitHub token via Envoy — the agent never handles credentials. + +*Multi-repo workflow example:* An agent implementing a feature that spans `kagenti/kagenti` and `kagenti/extensions` clones both repos, makes changes in each, commits to isolated branches, and pushes draft PRs to both. The human reviews each PR independently. + +*Trust boundary:* Changes stay in the sandbox until a human explicitly merges. The agent can push draft PRs (if `sources.json` allows `create-draft` scope for the target repo) but cannot merge, delete branches, or perform admin operations — those scopes are never granted via AuthBridge token exchange. + +**What we use:** Kubernetes init container (primary clone), agent shell tool (dynamic clones), AuthBridge for git auth, PVC for persistence. Patterns from paude (git `ext::` protocol), devaipod (`git clone --shared`), ai-shell (per-project volumes). + +**Relationship to other capabilities:** C1 (PVC persistence across restarts), C6 (AuthBridge provides scoped git auth — agent never handles tokens), C8 (sources.json `allowed_remotes` controls which repos can be cloned), C10 (skills loading reads from the primary clone), C4 (attestation verifies primary repo content after clone). + +--- + +### C10: Skills/CLAUDE.md Loading + +An agent without project context produces generic results. Skills loading parses repo instruction files into structured LLM context, giving the agent project-specific knowledge and workflows without manual configuration. + +**How it works:** `SkillsLoader` scans the cloned workspace for `CLAUDE.md` (system prompt) and `.claude/skills/` (workflow definitions). Each skill is loaded as a named workflow. The loader assembles a unified, model-agnostic context payload. Pattern from nanobot's context builder (SOUL.md, AGENTS.md, IDENTITY.md). + +**Security boundary:** Skills and CLAUDE.md are loaded **only from the primary repo** (the init container clone at `/workspace`). Dynamically cloned repos (C9 runtime clones at `/workspace/repos/`) are treated as data — the agent operates on their code but never loads instruction files from them. This prevents an attacker from crafting a malicious repo with poisoned skills that the agent clones and executes. + +**What we use:** Custom Python `SkillsLoader` class. + +**Relationship to other capabilities:** C9 (depends on primary repo being cloned; dynamic repos are data-only), C4 (depends on instruction files being verified), C11 (context is passed to any LLM via litellm). + +--- + +### C11: Multi-LLM Pluggability + +Locking to a single LLM provider creates vendor dependency. Skills should work identically regardless of which model powers the agent. + +**How it works:** litellm provides a unified `completion()` API across 100+ providers. Model selection via environment variables: `LLM_MODEL`, `LLM_API_BASE`, `LLM_API_KEY`. Switching models requires no code changes. The context from C10 is plain text, transferable across models. + +**What we use:** [litellm](https://github.com/BerriAI/litellm) — direct Python dependency. + +**Relationship to other capabilities:** C10 (receives assembled context), C5 (LLM API calls go through proxy sidecar). + +--- + +### C12: Token Exchange (AuthBridge) + +Sandbox agents need credentials for external services but storing static secrets violates least privilege and creates blast radius. Token exchange eliminates static secrets entirely. + +**How it works:** AuthBridge ext_proc performs RFC 8693 token exchange: presents the pod's SPIFFE SVID to Keycloak, receives a scoped, short-lived OAuth2 token, injects it into the outbound request. The agent code never handles credentials. Keycloak logs every exchange for audit. + +**What we use:** [AuthBridge](https://github.com/kagenti/kagenti-extensions/tree/main/AuthBridge), Keycloak, SPIRE. Already built. + +**Relationship to other capabilities:** C6 (AuthBridge IS the credential isolation implementation), C5 (proxy decides WHERE, AuthBridge decides WITH WHAT IDENTITY), C13 (same ext_proc does both token exchange and OTEL). + +--- + +### C13: Observability (AuthBridge OTEL) + +Understanding what an agent did is essential for debugging, auditing, and cost management. AuthBridge creates distributed traces at the mesh level with zero agent code changes. + +**How it works:** AuthBridge ext_proc intercepts inbound A2A requests, parses the body, and creates a root OTEL span `invoke_agent {name}` with GenAI semantic conventions (MLflow and OpenInference compatible). A `traceparent` header is injected so that auto-instrumented agent spans (LangChain, OpenAI SDK) become children of this root span. This is Approach A — the default on OpenShift. Alternative Approach B requires ~50 lines of agent boilerplate. + +**What we use:** AuthBridge ext_proc with OTEL SDK, MLflow. Already built. + +**Relationship to other capabilities:** C12 (same ext_proc handles both token exchange and trace creation), C6 (same infrastructure). + +--- + +### C14: Execution Approval + +When a tool call falls outside allow/deny rules, the agent must pause and ask a human. This is the escalation mechanism that turns static policy (C7) into a live decision point. + +**How it works:** The sandbox runtime classifies the operation as `requires_approval`. LangGraph calls `interrupt()`, suspending the graph and persisting state. The A2A task transitions to `input_required`. The approval request is delivered through C18's multi-channel system. The agent remains frozen until the human responds. Critically, the kernel-level sandbox (C3: nono) remains active throughout — unlike OpenClaw's approval system, Kagenti's enforcement cannot be disabled by any userspace process. + +**What we use:** LangGraph `interrupt()` + A2A `input_required` + settings.json HITL. Already built; needs extension for autonomous mode. + +**Relationship to other capabilities:** C7 (policy rules determine when approval is needed), C18 (delivers the request to humans), C3 (nono guarantees sandbox holds even if approval system were bypassed). + +--- + +### C15: Config Trust (TOFU) + +Agent configs directly control what the agent can do. A silently modified config could grant capabilities the operator never intended. + +**How it works:** On first load, the sandbox controller hashes each trust-sensitive file (SHA-256) and stores fingerprints in a ConfigMap. On subsequent sandbox creations, it re-hashes and compares. If any hash differs, the sandbox is not created — the controller emits a `ConfigTrustViolation` event and requires explicit re-approval. Pattern from ai-shell's `loader.go`. + +**What we use:** SHA-256 hashing + Kubernetes ConfigMap trust store. Replicate the concept independently (ai-shell has no license). + +**Relationship to other capabilities:** C4 (TOFU is simpler than Sigstore attestation — first-use trust vs cryptographic verification), C9 (runs after git clone, before agent loads configs), C10 (skills loading proceeds only after TOFU passes). + +--- + +### C16: Container Hardening Defaults + +Every sandbox pod must start from a secure baseline. Without enforced defaults, a single misconfigured template could expose the host kernel. + +**How it works:** The SandboxTemplate controller injects non-negotiable settings: read-only root filesystem, all capabilities dropped, non-root user, no service account token auto-mount, default-deny NetworkPolicy. Defined in Helm `values.yaml` under `sandboxDefaults`. Individual templates can add permissions but cannot weaken the baseline. + +**What we use:** Kubernetes SecurityContext + NetworkPolicy + PodSecurity admission, configured as SandboxTemplate defaults. Pattern from agent-sandbox and [Anthropic secure deployment guide](https://platform.claude.com/docs/en/agent-sdk/secure-deployment). + +**Relationship to other capabilities:** C1 (SandboxTemplate carries these defaults), C2 (gVisor/Kata adds kernel isolation above), C3 (nono adds syscall enforcement below), C5 (NetworkPolicy refined with per-agent egress rules). + +--- + +### C17: Autonomous Triggers + +Agents become substantially more useful when invoked automatically in response to events rather than only through manual interaction. + +**How it works:** The Kagenti backend exposes FastAPI endpoints for trigger registrations. A trigger binds an event source (cron expression, webhook URL, PagerDuty alert filter, A2A message pattern) to a SandboxTemplate and parameters. When an event arrives, the backend creates a `SandboxClaim` CRD via kubernetes-client. The agent-sandbox controller provisions the pod, clones the repo (C9), validates config trust (C15), and starts the agent. + +**What we use:** New Kagenti backend feature — FastAPI trigger endpoints + SandboxClaim CRD. To be built. + +**Relationship to other capabilities:** C1 (SandboxClaim is the API for programmatic creation), C18 (triggers spawn sandboxes, HITL is how the sandbox talks back to humans), C9 (each trigger clones the relevant repo/branch). + +--- + +### C18 Deep-Dive: Multi-Source Conversational HITL for Autonomous Agents + +This goes beyond simple approve/deny. An autonomous agent working on a GitHub PR, an incident, or a scheduled task needs the ability to have a **multi-turn conversation** with humans through contextual channels — asking clarifying questions, presenting options, receiving design input — all tied to the relevant external resource (PR, Issue, incident) and routed to the right session. + +#### The Problem + +When an autonomous agent encounters something it cannot resolve alone — an ambiguous requirement, a design decision, a risky operation — it needs to: + +1. **Ask a question** (not just request a binary approval) +2. **In the right context** (the PR thread, the Slack channel, the incident timeline) +3. **To the right person** (the PR author, the on-call engineer, the team lead) +4. **And get the answer back** into the same agent session (same `contextId`) +5. **Securely** — only authorized humans can inject input into the agent session + +#### Context Binding: `contextId` ↔ External Resource + +Every agent session has an A2A `contextId`.

Kagenti's Approval Backend is a multi-channel `WebhookApproval` that routes to GitHub/Slack/UI/PagerDuty. + +2. **A2A protocol's [`input_required` state](https://a2a-protocol.org/latest/tutorials/python/7-streaming-and-multiturn/)** — the agent pauses and waits for the next `message/send` with the same `contextId`. The Kagenti backend acts as a bridge: it receives human input from any channel and forwards it as an A2A message to the sandbox. + +The lesson from [OpenClaw's CVE-2026-25253](https://thehackernews.com/2026/02/openclaw-bug-enables-one-click-remote.html): their control API could disable the sandbox from outside. In Kagenti's design, the human input channel can only **send messages** to the agent — it cannot reconfigure the sandbox, disable permissions, or change the execution host. Those controls are enforced at the kernel level (nono Landlock) and cannot be modified via any API. + +### C19: Multi-Conversation Isolation + +When a sandbox agent handles multiple concurrent conversations — different users or different A2A callers hitting the same pod — each conversation's workspace, memory, and credentials must be isolated. Without this, one user's data could leak into another user's session. + +**How it works:** Two modes based on security requirements: + +*Pod-per-conversation (autonomous mode):* The agent-sandbox controller creates a separate Sandbox (and pod) for each conversation. This provides process-level, filesystem-level, and network-level isolation between conversations. Higher resource cost, but the only safe option for autonomous agents handling untrusted input. + +```yaml +# Each conversation gets its own SandboxClaim +apiVersion: agents.x-k8s.io/v1alpha1 +kind: SandboxClaim +metadata: + name: conv-abc123 + labels: + kagenti.io/conversation-id: abc123 + kagenti.io/user: alice +spec: + sandboxTemplateName: coding-agent +``` + +*Shared pod with per-context directories (interactive mode):* A single pod handles multiple conversations, each in a separate workspace directory under the shared PVC. The `WorkspaceManager` creates `/workspace/ctx-/` directories with separate `.context.json` metadata. Acceptable when a human is watching (interactive mode), because the human provides the trust boundary. + +``` +/workspace/ +├── ctx-abc123/ # Alice's conversation +│ ├── .context.json # {user: alice, created_at: ..., ttl_days: 7} +│ ├── repo/ # Cloned code +│ └── .cache/ # Conversation-specific cache +├── ctx-def456/ # Bob's conversation +│ ├── .context.json # {user: bob, created_at: ..., ttl_days: 7} +│ └── repo/ +``` + +*Memory isolation:* For pod-per-conversation, each pod has its own `MemorySaver` — no shared state. For shared-pod mode, the checkpointer uses conversation-scoped keys: `thread_id = f"ctx-{context_id}"` so that LangGraph's state graph never crosses conversation boundaries. + +*Credential isolation:* AuthBridge handles this at the request level — each inbound A2A request carries the caller's JWT, and ext_proc exchanges it for a scoped token tied to that caller's identity. Different conversations get different scoped tokens automatically. + +**What we use:** Kubernetes SandboxClaim (autonomous) + WorkspaceManager per-context dirs (interactive). AuthBridge for credential scoping. + +**Relationship to other capabilities:** C1 (SandboxClaim creates pods per conversation), C6 (AuthBridge scopes credentials per caller), C14 (HITL approval is per-conversation), C18 (context registry binds contextId to external resources). + +--- + +### C20: Sub-Agent Spawning via LangGraph + +Complex tasks require the parent agent to delegate work to specialized sub-agents — similar to how Claude Code uses `Task` with `subagent_type=Explore` for research. The sandbox must support spawning sub-agents at two isolation levels. + +**How it works:** Two spawning modes: + +*In-process sub-agents (fast, same pod):* LangGraph `StateGraph` composition — the parent graph has tool nodes that invoke child graphs as asyncio tasks within the same Python process. Each sub-agent gets a scoped tool set (e.g., explore sub-agent gets only read tools, no write/execute). Good for research, analysis, and codebase exploration. + +```python +from langgraph.graph import StateGraph + +@tool +async def explore(query: str) -> str: + """Spawn an explore sub-agent for codebase research.""" + sub_graph = create_explore_graph( + workspace="/workspace/repo", + tools=["grep", "read_file", "glob"], # Scoped: no write, no execute + max_iterations=15, + ) + result = await sub_graph.ainvoke({"query": query}) + return result["summary"] + +@tool +async def analyze(file_path: str, question: str) -> str: + """Spawn an analysis sub-agent for code review.""" + sub_graph = create_analysis_graph( + workspace="/workspace/repo", + tools=["read_file"], # Read-only + max_iterations=10, + ) + result = await sub_graph.ainvoke({"file": file_path, "question": question}) + return result["analysis"] +``` + +*Out-of-process sub-agents (isolated, separate pods):* The parent agent creates a `SandboxClaim` with the sub-task description and waits for the result via A2A polling. Each sub-agent gets its own sandbox pod with full isolation. Good for untrusted or long-running tasks. + +```python +@tool +async def delegate(task: str, skill: str) -> str: + """Spawn a sandbox sub-agent for a delegated task.""" + trigger = SandboxTrigger(namespace="team1") + claim_name = trigger.create_from_webhook( + event_type="a2a_delegation", + repo="kagenti/kagenti", + branch="main", + skill=skill, # Sub-agent loads this skill as primary workflow + ) + # Poll A2A endpoint until task completes + return await poll_sandbox_result(claim_name, timeout=300) +``` + +*Skill-driven sub-agent selection:* The parent agent reads the skills index from `CLAUDE.md` / `.claude/skills/` and uses the LLM to decide which skill to invoke and whether to use in-process or out-of-process spawning: + +| Task Type | Spawning Mode | Example | +|-----------|---------------|---------| +| Codebase research | In-process (asyncio) | "Find all API endpoints" | +| Code analysis | In-process (asyncio) | "Review this function for bugs" | +| Test writing | Out-of-process (A2A) | "Write E2E tests for /users endpoint" | +| CI debugging | Out-of-process (A2A) | "Run /rca:ci on failing pipeline" | +| Multi-repo changes | Out-of-process (A2A) | "Update extensions repo to match" | + +**What we use:** LangGraph StateGraph composition (in-process), SandboxClaim + A2A (out-of-process), SkillsLoader for sub-agent skill selection. + +**Relationship to other capabilities:** C1 (SandboxClaim for out-of-process sub-agents), C10 (skills determine which sub-agent type), C19 (each sub-agent conversation is isolated), C11 (sub-agents can use different LLM models via litellm). + +--- + +### C21: A2A-Generic Session Persistence + +Session data must be available to the Kagenti UI regardless of which agent framework produced it. Rather than building framework-specific persistence (e.g., LangGraph AsyncPostgresSaver), the A2A SDK's DatabaseTaskStore persists tasks, messages, artifacts, and contextId at the protocol level. + +**How it works:** The A2A SDK's `DatabaseTaskStore` replaces `InMemoryTaskStore` in the agent's server configuration. It uses SQLAlchemy async with PostgreSQL (asyncpg driver). Every `message/send` and task state change is persisted automatically. The Kagenti backend reads from the same database to power the session UI. + +**Two-layer persistence:** +- **A2A TaskStore (all agents):** Tasks, messages, artifacts, contextId. Framework-agnostic. Read by UI. +- **Framework checkpointer (optional):** LangGraph AsyncPostgresSaver for graph pause/resume. Internal to Sandbox Legion. + +**Agent variant: Sandbox Legion** — the flagship LangGraph-based multi-sub-agent orchestrator that uses both layers. Future agents (CrewAI, AG2) use only the A2A TaskStore. + +**What we use:** [a2a-sdk[postgresql]](https://github.com/a2aproject/a2a-python) `DatabaseTaskStore`, per-namespace PostgreSQL (postgres-sessions StatefulSet). + +**Relationship to other capabilities:** C19 (contextId links conversations to workspaces), C20 (sub-agent results stored as nested tasks), C14 (HITL state persisted as task state transitions). + +--- + +### Capability Overlaps and Alignment + +Several capabilities share infrastructure or address the same threat from different angles. Understanding these relationships prevents redundant work and ensures defense-in-depth. + +**AuthBridge cluster (C6 + C12 + C13):** These three capabilities are implemented by the same component — AuthBridge ext_proc in the Envoy mesh. Token exchange (C12), credential isolation (C6), and observability (C13) all happen in a single request interception path. This is an architectural strength: one component, one interception point, minimal latency overhead. + +**Permission stack (C3 + C7 + C14):** Three layers of execution control at different levels. nono (C3) operates at the kernel level — it cannot be disabled. settings.json (C7) operates at the application level — it defines policy. Execution approval (C14) is the escalation mechanism when C7 encounters an ambiguous operation. If C14's approval system were somehow bypassed, C3's kernel enforcement still holds. This layering is what prevented OpenClaw-style sandbox escapes. + +**Trust verification chain (C4 + C15 + C9):** Three capabilities that verify content integrity at different stages. C9 (git clone) brings the code into the sandbox. C15 (TOFU) checks that config files haven't changed since the last trusted load. C4 (attestation) provides cryptographic proof of provenance. They form a pipeline: clone → hash check → signature verification → load. + +**Network control stack (C5 + C6 + C16):** Three capabilities controlling network access at different layers. C16 (NetworkPolicy) restricts at L3/L4 (IP/port). C5 (Squid proxy) restricts at L7 (domain names). C6 (AuthBridge) controls the identity used for authenticated connections. A compromised agent must bypass all three to exfiltrate data. + +**Agent context chain (C9 → C15 → C4 → C10 → C11):** Sequential dependencies for loading and using skills. Repo is cloned (C9), configs are hash-checked (C15), instruction files are signature-verified (C4), skills are parsed into context (C10), and context is sent to any LLM (C11). Breaking any link in this chain prevents the agent from loading poisoned instructions. + +**Trigger-to-response cycle (C17 → C1 → C14 → C18):** The full autonomous lifecycle. A trigger creates a SandboxClaim (C17), the controller provisions a pod (C1), the agent runs until it hits a HITL operation (C14), the approval request is delivered to a human (C18), and the response is routed back to the sandbox. This cycle can repeat multiple times within a single sandbox session. + +--- + +### Projects: Use Directly vs. Replicate Concepts + +**Use directly as dependencies (Apache-2.0 compatible):** + +| Project | License | What to adopt | Why direct adoption | +|---------|---------|---------------|---------------------| +| [kubernetes-sigs/agent-sandbox](https://github.com/kubernetes-sigs/agent-sandbox) | Apache-2.0 | Sandbox CRD, controller, warm pools | K8s-native standard; no reason to rebuild | +| [always-further/nono](https://github.com/always-further/nono) | Apache-2.0 | Kernel sandbox (Landlock/Seatbelt), Python bindings | Kernel-enforced isolation cannot be replicated at application level | +| [litellm](https://github.com/BerriAI/litellm) | MIT | Multi-LLM API abstraction | 100+ providers, battle-tested, no reason to rebuild | + +**Replicate concepts (build Kagenti-native implementations inspired by):** + +| Project | License | Concept to replicate | Why replicate instead of adopt | +|---------|---------|---------------------|-------------------------------| +| [bbrowning/paude](https://github.com/bbrowning/paude) | MIT | Squid proxy sidecar for network filtering | Paude is Claude-specific; we need a generic proxy sidecar | +| [cgwalters/devaipod](https://github.com/cgwalters/devaipod) | MIT/Apache-2.0 | Credential isolation via scoped MCP proxy | Devaipod uses Podman; we map this to Keycloak token exchange | +| [HKUDS/nanobot](https://github.com/HKUDS/nanobot) | MIT | Context builder from bootstrap files (SOUL.md → CLAUDE.md) | Nanobot is a full agent framework; we only need the loader pattern | +| [openclaw/openclaw](https://github.com/openclaw/openclaw) | MIT | **Cautionary example** — exec approval concepts, but platform has had [512 vulnerabilities](https://www.kaspersky.com/blog/openclaw-vulnerabilities-exposed/55263/), [312K exposed instances](https://www.infosecurity-magazine.com/news/researchers-40000-exposed-openclaw/), and [1-click RCE via sandbox bypass](https://thehackernews.com/2026/02/openclaw-bug-enables-one-click-remote.html) | Study the failure modes, do not adopt the implementation | +| [arewm/ai-shell](https://github.com/arewm/ai-shell) | **No license** | TOFU config trust, per-project volume isolation | ⚠️ Cannot use directly — no license file.

The implementation covers container-level isolation (CRDs + controller), network filtering (Squid proxy), kernel sandboxing (nono Landlock), skills loading, TOFU verification, autonomous triggers, and HITL scaffolding. gVisor runtime isolation is deferred due to SELinux incompatibility on RHCOS (see C2 section).

The LLM can trivially wrap any denied command in an allowed interpreter. | Critical | Squid proxy blocks `curl` at the network level (domain allowlist). nono Landlock blocks filesystem access. NetworkPolicy blocks direct IP connections. **Three layers prevent actual exfiltration even if the permission check is bypassed.** | Add recursive argument inspection in `_match_shell()` for interpreter commands (detect `-c` flags, pipe chains, subprocess spawning). Or: remove blanket `shell(bash:*)` / `shell(python:*)` from allow rules and whitelist specific scripts instead. | 🔄 Pending | +| 2 | **HITL has no `interrupt()` call** — `HitlRequired` exception is caught and converted to a string (`"APPROVAL_REQUIRED: ..."`), returned to the LLM. No LangGraph `interrupt()` is called, so the graph continues and the LLM can ignore or work around the approval request. | Critical | Phase 8 HITLManager provides the proper approval backend infrastructure (ContextRegistry, channel adapters, ApprovalRequest/Decision model). **The infrastructure is ready; the agent code just needs to call `interrupt()` instead of returning a string.** | Replace `except HitlRequired` handler with LangGraph `interrupt()` that pauses graph execution. Agent resumes only after explicit human approval via the HITLManager channel. | 🔄 Pending | +| 3 | **No TTL / workspace cleanup** — `ttl_days` is accepted and stored in `.context.json` but never enforced. No cleanup job, no eviction, no disk quota enforcement. Workspaces accumulate indefinitely on shared PVC. | Medium | SandboxClaim has `shutdownTime` + `Delete` policy (Phase 1, C1). **The Sandbox controller handles pod lifecycle and PVC cleanup.** However, within a shared pod (interactive mode, C19), per-context dirs are not cleaned up. | Add `cleanup_expired()` method to `WorkspaceManager`, wire into CronJob or startup hook. Or: document `ttl_days` as advisory and defer enforcement to Sandbox controller lifecycle. | 🔄 Pending | +| 4 | **Package/remote blocking not wired** — `is_package_blocked()`, `is_git_remote_allowed()`, `is_package_manager_enabled()` exist in `sources.py` but are never called from the executor. `pip install ` succeeds if `shell(pip install:*)` is in the allow list. | Medium | Phase 5 RepoManager enforces `sources.json` `allowed_remotes` for `git clone` operations. Squid proxy blocks access to unlisted package registries at the network level. **Infrastructure enforcement partially covers this, but the app-level check provides defense in depth.** | Wire `is_package_blocked()` and `is_git_remote_allowed()` into executor pre-hooks. Before executing any `pip install`, `git clone`, or `npm install` command, check against `sources.json`. | 🔄 Pending | + +**Defense-in-depth analysis:** The infrastructure layers (Phases 1-9) mitigate the real-world impact of all 4 findings. Even if the application-level permission checker is bypassed (Finding 1), the Squid proxy blocks unauthorized network access, nono Landlock blocks unauthorized filesystem access, and NetworkPolicy prevents direct IP connections. However, the application-level fixes are still important for: (a) defense in depth, (b) providing clear feedback to the LLM about why an operation was denied, and (c) preventing the LLM from wasting tokens on operations that will ultimately fail at the infrastructure level. + +--- + +## 5.

Install agent-sandbox controller on lpvc cluster +2. Create `SandboxTemplate` with: gVisor RuntimeClass, read-only root, all caps dropped, non-root, no SA auto-mount, default-deny NetworkPolicy +3. Create a test `Sandbox` from the template — verify pod starts with gVisor +4. Verify headless Service + stable DNS + +**Key files:** `.worktrees/sandbox_research/agent-sandbox/k8s/` + +**OPEN ISSUE — gVisor + SELinux incompatibility (2026-02-24):** + +gVisor (runsc) rejects any SELinux label. On OpenShift, CRI-O always applies SELinux process labels (`container_t`), causing `CreateContainerError`. This is fundamental — gVisor intercepts syscalls in user-space and does not implement SELinux MAC. + +**Current approach: gVisor is optional, deferred to end.** Sandbox works with runc + SecurityContext hardening (C16) + nono Landlock (C3). gVisor adds C2 runtime isolation when the SELinux issue is resolved. + +**What we lose disabling SELinux for sandbox pods:** +- **Mandatory Access Control (MAC)** — SELinux prevents processes from accessing files/ports/resources outside their assigned type, even if DAC (Unix permissions) would allow it +- **Container breakout prevention** — SELinux `container_t` type prevents a compromised container from accessing host files, other containers' filesystems, or sensitive kernel interfaces +- **Inter-container isolation** — MCS (Multi-Category Security) labels (`s0:c27,c24`) ensure containers in the same pod can't read each other's files + +**What gVisor provides instead (stronger in many areas):** +- **Complete syscall interception** — gVisor implements its own kernel (Sentry) that intercepts ALL ~350 Linux syscalls. A compromised process can only make syscalls that gVisor explicitly implements (~70% coverage). SELinux only restricts file/network/IPC access, not arbitrary syscalls. +- **Kernel vulnerability isolation** — host kernel CVEs don't affect gVisor-sandboxed containers because they never touch the real kernel. SELinux runs on the shared kernel. +- **Reduced attack surface** — gVisor's Sentry has ~200K lines of Go vs Linux kernel's ~28M lines of C. Smaller codebase = fewer exploitable bugs. +- **Filesystem isolation** — gVisor's Gofer process mediates all filesystem access (overlay, tmpfs, bind mounts). No direct kernel VFS access. + +**Why Kata Containers is the long-term solution (label: later):** +Kata provides VM-level isolation (each pod = lightweight VM with its own kernel) AND supports SELinux on the host. It's Red Hat's officially supported sandbox runtime via the OpenShift Sandboxed Containers operator. Trade-offs: +- Requires `/dev/kvm` on nodes (bare metal or metal instances on AWS) or "peer pods" mode (separate EC2 instance per sandbox, higher cost) +- 100-500ms boot overhead per pod (vs gVisor ~100ms) +- Higher memory footprint per pod (~128MB VM overhead) +- Strongest isolation of all options — full kernel boundary + SELinux + seccomp + +**Recommendation:** Ship with runc + C16 + C3 now. Add gVisor (with SELinux wrapper) or Kata as optional RuntimeClass upgrades. Do NOT disable SELinux cluster-wide. + +### Phase 2: Network + Auth (C5, C6, C12) + +**Goal:** Add Squid proxy sidecar and verify AuthBridge token exchange works in sandbox pods. + +1. Build Squid proxy sidecar container image (from paude pattern) +2. Add proxy sidecar to SandboxTemplate +3. Verify AuthBridge ext_proc works with sandbox pods (namespace label) +4. Test: agent makes GitHub API call → AuthBridge exchanges SVID → scoped token → Squid allows domain +5. Test: agent tries curl to evil.com → Squid blocks + +**Key files:** `paude/containers/proxy/squid.conf`, `charts/kagenti/templates/agent-namespaces.yaml` + +### Phase 3: Kernel Sandbox (C3) + +**Goal:** Add nono Landlock enforcement inside the agent container. + +1. Install nono Python bindings (`pip install nono-py`) +2. Wrap agent startup: `nono.sandbox()` → apply CapabilitySet → then start agent +3. Configure: allow `/workspace/**` RW, deny `~/.ssh`, `~/.kube`, `~/.aws`, `/etc/shadow` +4. Test: agent can read/write workspace; cannot read `~/.ssh` + +**Key files:** `.worktrees/sandbox_research/nono/crates/nono/src/capability.rs` + +### Phase 4: Skills Loading + Multi-LLM (C9, C10, C11) + +**Goal:** Clone primary repo at init, load CLAUDE.md + skills, plug any LLM via litellm. + +1. Add init container to SandboxTemplate: `git clone /workspace` +2. Build SkillsLoader: parse CLAUDE.md → system prompt, .claude/skills/ → workflow index +3. Integrate litellm: environment-variable-driven model selection +4. Test: sandbox starts, loads skills, answers questions using the repo's CLAUDE.md context +5. Test: switch LLM_MODEL env var → same skills work with different model + +### Phase 5: Multi-Repo + Git Auth (C9 dynamic) + +**Goal:** Agent can clone additional repos at runtime via AuthBridge. + +1. Configure sources.json `allowed_remotes`: `https://github.com/kagenti/*` +2. Test: agent runs `git clone https://github.com/kagenti/kagenti-extensions` → AuthBridge injects token → clone succeeds +3. Test: agent tries to clone a repo NOT in allowed_remotes → blocked by sources.json +4. Test: agent pushes draft PR to both repos + +### Phase 6: Trust Verification (C4, C15) + +**Goal:** TOFU for config files, optional Sigstore attestation for instruction files. + +1. Implement TOFU: hash CLAUDE.md + settings.json + sources.json on first load, store in ConfigMap +2. On subsequent sandbox creation, verify hashes match → block if changed +3. (Optional) Add Sigstore verification for CLAUDE.md in production mode + +### Phase 7: Autonomous Triggers (C17) + +**Goal:** Kagenti backend creates SandboxClaims from cron/webhook/alert events. + +1. Add FastAPI endpoint: `POST /api/v1/sandbox/trigger` → creates SandboxClaim +2. Add cron trigger support: register schedule → backend creates SandboxClaim on tick +3. Add GitHub webhook trigger: `PR opened` → backend creates SandboxClaim with PR branch +4. Test: nightly cron → sandbox runs `/rca:ci` → pushes draft PR with findings + +### Phase 8: HITL Delivery (C14, C18) + +**Goal:** Multi-channel approval/conversation routing for autonomous agents. + +1. Build Approval Backend in Kagenti backend (Context Registry + channel adapters) +2. Add GitHub adapter: agent posts to PR comment, human replies, routed back to contextId +3. Add Slack adapter: interactive messages with approve/deny buttons +4. Add Kagenti UI adapter: approval queue with WebSocket push +5. Test: agent hits HITL → posts to PR → human approves → agent resumes + +### Phase 9: Observability (C13) + +**Goal:** Verify AuthBridge OTEL root spans work with sandbox pods + MLflow. + +1. Verify ext_proc creates root span with GenAI/MLflow attributes for sandbox agent +2. Verify agent's LangChain auto-instrumented spans are children of root span +3. Verify traces appear in MLflow UI +4.

Each conversation must be isolated — one conversation's workspace, context, and state must not leak to another. + +**Current POC approach:** `WorkspaceManager` creates per-context directories under a shared PVC: +``` +/workspace/ +├── ctx-abc123/ # Conversation 1's workspace +│ ├── .context.json +│ └── repo/ +├── ctx-def456/ # Conversation 2's workspace +│ ├── .context.json +│ └── repo/ +``` + +**Design questions for next session:** +1. **Process-level isolation:** Should each conversation run in a separate process (fork/exec) with its own nono Landlock sandbox? This would prevent one conversation's compromised process from accessing another's workspace. +2. **Pod-per-conversation vs shared pod:** The agent-sandbox controller creates one pod per Sandbox. Should we create one Sandbox per conversation (strongest isolation, higher resource cost) or multiplex conversations on one pod (lower cost, weaker isolation)? +3. **Memory isolation:** LangGraph's `MemorySaver` is in-process. Multi-conversation needs either separate checkpointers per conversation or a shared store with strict key isolation. +4. **Credential isolation:** Each conversation may need different scoped tokens (e.g., one user's GitHub token vs another's). AuthBridge handles this at the request level, but the agent process needs to track which credentials belong to which conversation. + +**Recommended approach:** One Sandbox pod per conversation for security-critical workloads (autonomous mode). Shared pod with per-context workspace isolation for interactive mode (lower cost, acceptable risk since the human is watching). + +### C20: Sub-Agent Spawning via LangGraph + +**Problem:** A sandbox agent needs to spawn sub-agents for parallel work — similar to how Claude Code uses the `Task` tool with `subagent_type=Explore` to delegate research. The sandbox should support: +1. Spawning sub-agents within the same LangGraph graph (asyncio tasks) +2. Spawning sub-agents in separate sandbox pods (A2A delegation) +3. Loading different skills for different sub-agents + +**Current patterns:** +- **Claude Code Explore agent:** Spawns a sub-process with limited tools (Grep, Read, Glob) for codebase research. Returns a summary. +- **LangGraph sub-graphs:** A parent graph can invoke child graphs as tools. Each sub-graph runs as an asyncio task in the same process. +- **A2A delegation:** A planning agent sends an A2A message to spawn a separate sandbox agent with its own task. + +**Design for next session:** +1. **In-process sub-agents (fast, same pod):** Use LangGraph's `StateGraph` composition — parent graph has tool nodes that invoke child graphs. Child graphs run as asyncio tasks sharing the same Python process.

VSO runs one controller per cluster rather than one sidecar per pod, reducing total resource consumption significantly. + +### 1.3 HA vs Single-Node + +| Mode | When to Use | Vault Pods | Storage | +|------|------------|------------|---------| +| **Dev mode** (`server.dev.enabled: true`) | Local testing, demos | 1 | In-memory (data lost on restart) | +| **Standalone** (`server.standalone.enabled: true`) | Dev/test clusters, CI | 1 | 1Gi PVC (Raft or file) | +| **HA Raft** (`server.ha.enabled: true, server.ha.raft.enabled: true`) | Production | 3-5 | 25Gi+ PVC per node | + +For Kagenti dev/test on HyperShift clusters, **standalone mode** is the right choice. It persists data across restarts but avoids the overhead of a 3-5 node Raft cluster. + +### 1.4 Raft Integrated Storage vs Consul Backend + +| Feature | Integrated Storage (Raft) | Consul Backend | +|---------|--------------------------|----------------| +| **Status** | **Recommended** (current default) | Supported (legacy) | +| **Data persistence** | On-disk (disk I/O bound) | In-memory (RAM bound) | +| **Infrastructure** | Self-contained (Vault only) | Requires separate Consul cluster | +| **Total pods (HA)** | 3-5 Vault pods | 3 Vault + 5 Consul pods (8 total) | +| **Operational complexity** | Lower | Higher (two clusters to manage) | +| **Backup frequency** | Less frequent (data on disk) | Frequent (data in memory) | + +**Verdict:** Use Raft integrated storage. It eliminates the need for a Consul cluster and is HashiCorp's current recommendation. For Kagenti, this means deploying only the Vault Helm chart, not Consul. + +--- + +## 2. Integration with Kagenti + +### 2.1 Replace Kubernetes Secrets with Vault Dynamic Secrets + +Currently, Kagenti stores credentials (GitHub PATs, LLM API keys, OAuth client secrets) as Kubernetes Secrets in agent namespaces. Vault replaces this with: + +| Current Pattern | Vault Pattern | +|----------------|---------------| +| `kubectl create secret generic openai-key --from-literal=key=sk-...` | Vault KV or dynamic secrets engine | +| Secret mounted as env var or file in agent pod | VSO syncs to K8s Secret, or Agent Injector writes to `/vault/secrets/` | +| Manual rotation (delete + recreate secret) | Automatic rotation via TTL or `rotation_period` | +| Visible in `kubectl get secrets` (base64 encoded) | Encrypted at rest in Vault, audit-logged | + +**Migration path for Kagenti:** + +1. Deploy Vault in `vault` namespace (standalone, Raft storage) +2. Install VSO from OperatorHub +3. Store existing secrets in Vault KV v2 (`secret/kagenti/team1/openai-key`) +4. Create `VaultStaticSecret` CRs in agent namespaces to sync secrets +5. Gradually move to dynamic secrets engines for credentials that support it + +Example `VaultStaticSecret` for an agent namespace: +```yaml +apiVersion: secrets.hashicorp.com/v1beta1 +kind: VaultStaticSecret +metadata: + name: openai-key + namespace: team1 +spec: + vaultAuthRef: vault-auth + mount: secret + path: kagenti/team1/openai-key + type: kv-v2 + refreshAfter: 60s + destination: + name: openai-key # K8s Secret name + create: true +``` + +### 2.2 Agent Credential Rotation + +#### GitHub PATs / Installation Tokens + +**Problem:** Sandbox agents need GitHub access for cloning repos, creating branches, and opening PRs. Long-lived PATs are a security risk. + +**Solution: vault-plugin-secrets-github** (community plugin by Martin Baillie) + +This plugin uses a GitHub App to generate ephemeral, scoped installation tokens: + +1. Register a GitHub App with the required permissions (contents:write, pull_requests:write) +2. Configure the plugin with the App's private key +3. Agents request tokens scoped to specific repos +4. Tokens expire after 1 hour (GitHub's maximum for installation tokens) + +```bash +# Configure the GitHub secrets engine +vault write github/config \ + app_id=123456 \ + prv_key=@github-app-private-key.pem + +# Agent requests a scoped token +vault read github/token \ + installation_id=789 \ + repositories=org/repo1,org/repo2 \ + permissions=contents:write,pull_requests:write +``` + +**Integration with AuthBridge:** AuthBridge's `ext_proc` can request tokens from Vault instead of directly from GitHub, using Vault's Kubernetes auth to authenticate. + +#### LLM API Keys (OpenAI, Anthropic) + +**Option A: Vault KV with Auto-Rotation (simple)** +- Store API keys in Vault KV v2 +- Use VSO to sync to K8s Secrets with `refreshAfter: 60s` +- Manual rotation: update in Vault, VSO propagates to all agent pods + +**Option B: Vault OpenAI Dynamic Secrets Plugin (advanced)** +- Community plugin: `vault-plugin-secrets-openai` +- Generates ephemeral OpenAI API keys with TTL (e.g., 1 hour) +- Keys auto-expire; no manual cleanup +- Currently supports OpenAI only; Anthropic would need a custom plugin or KV approach + +```bash +# Configure OpenAI secrets engine +vault write openai/config \ + admin_api_key="sk-admin-..." \ + organization_id="org-123456" \ + rotation_period=604800 + +# Create a role with 1h TTL +vault write openai/roles/sandbox-agent \ + ttl=1h max_ttl=24h + +# Agent requests credentials +vault read openai/creds/sandbox-agent +# Returns: api_key, lease_id, lease_duration +``` + +#### Slack / Webhook Tokens + +Store in Vault KV v2 with periodic rotation. Use VSO `VaultStaticSecret` to sync. + +### 2.3 Integration with SPIRE (Vault Auth via SPIFFE SVIDs) + +Kagenti already runs SPIRE for workload identity. Vault supports SPIFFE as a native auth method (Vault Enterprise 1.21+) or via OIDC federation (open source). + +#### Option A: Native SPIFFE Auth (Vault Enterprise 1.21+) + +```bash +# Enable SPIFFE auth +vault auth enable spiffe + +# Configure trust domain from SPIRE +vault write auth/spiffe/config \ + trust_domain="kagenti" \ + trust_bundle_url="https://spire-server.spire-system.svc:8443/bundle" + +# Create a role mapping SPIFFE IDs to Vault policies +vault write auth/spiffe/roles/sandbox-agent \ + workload_id_patterns="ns/team1/sa/*,ns/team2/sa/*" \ + token_policies="sandbox-agent-policy" +``` + +Agent pods authenticate to Vault using their SPIFFE SVID (X.509 or JWT) -- no service account tokens or app-role credentials needed. + +#### Option B: SPIRE OIDC Federation with Vault JWT Auth (Open Source) + +For Vault open-source / community edition: + +1. Configure SPIRE to expose an OIDC Discovery endpoint +2. Configure Vault's JWT auth method to trust SPIRE as an OIDC provider +3. Agents present their JWT-SVID to Vault and receive a Vault token + +```bash +# Enable JWT auth +vault auth enable jwt + +# Configure SPIRE as OIDC provider +vault write auth/jwt/config \ + oidc_discovery_url="https://spire-oidc.spire-system.svc" \ + default_role="sandbox-agent" + +# Create role +vault write auth/jwt/role/sandbox-agent \ + role_type="jwt" \ + bound_audiences="vault" \ + user_claim="sub" \ + bound_subject="spiffe://kagenti/ns/team1/sa/sandbox-agent" \ + token_policies="sandbox-agent-policy" \ + token_ttl=1h +``` + +#### Option C: Kubernetes Auth (Simplest, No SPIRE Dependency) + +If SPIRE integration is not required for Vault auth specifically: + +```bash +vault auth enable kubernetes + +vault write auth/kubernetes/config \ + kubernetes_host="https://kubernetes.default.svc" + +vault write auth/kubernetes/role/sandbox-agent \ + bound_service_account_names="sandbox-agent,sandbox-legion" \ + bound_service_account_namespaces="team1,team2" \ + policies="sandbox-agent-policy" \ + ttl=1h +``` + +**Recommendation for Kagenti:** Start with Kubernetes auth (Option C) for simplicity. Add SPIRE OIDC federation (Option B) when you want zero-secret auth. Option A requires Vault Enterprise. + +### 2.4 Integration with AuthBridge (Vault as Credential Backend) + +Currently, AuthBridge reads credentials from Kubernetes Secrets. With Vault: + +``` +Agent pod ──SPIFFE SVID──> AuthBridge ext_proc ──Vault API──> Dynamic Credential + │ + ├── Vault Kubernetes auth (SA token) + ├── vault read github/token (scoped GitHub token) + ├── vault read openai/creds/role (dynamic LLM key) + └── Injects credential into outbound request +``` + +**Changes needed in AuthBridge:** +1. Add a Vault client (e.g., `hvac` Python library or Vault HTTP API) +2. On startup, authenticate to Vault using Kubernetes SA token +3. For each outbound request, look up the `SandboxTokenPolicy` CRD +4. Request the appropriate credential from Vault (GitHub token, LLM key, etc.) +5. Inject the credential into the Authorization header +6. Vault handles TTL, rotation, and audit logging + +This replaces the current pattern where AuthBridge reads from Kubernetes Secrets and manually manages credential lifecycles. + +--- + +## 3.

Today, a human operator manually writes passover documents and starts new sessions. This is brittle: context rots silently, state leaks between unrelated conversations, and there is no structured way to pause for human review at meaningful checkpoints. + +This design introduces **session orchestration** -- a system for managing session lifecycles, hierarchies, automated handoffs, and human-in-the-loop gates. The goals are: + +1. **Isolation**: Each chat sticks to one `context_id`. No state leaks between sessions. +2. **Hierarchy**: Parent-child session relationships are tracked and visible in the UI. +3. **Automated passover**: When a session's context grows too large, the agent creates a new session with a structured summary, without human intervention. +4. **HITL milestones**: The agent pauses at defined milestones for human review before proceeding. +5. **Auto-approve**: Humans can pre-approve N upcoming passovers or milestones, letting the agent run unattended for a bounded stretch. + +--- + +## 1. Session Data Model + +### 1.1 Current State + +The A2A SDK's `tasks` table stores all session data: + +``` +tasks + id SERIAL PRIMARY KEY + context_id VARCHAR(36) + kind VARCHAR(20) -- "task" + status JSON -- {state, message, timestamp} + metadata JSON -- {agent_name, title, ref, parent_context_id, ...} + artifacts JSON -- [{parts: [{kind, text}]}] + history JSON -- [{role, parts, messageId}] +``` + +The `metadata` JSON column is the extension point. It already has `agent_name`, `title`, and `ref`. The field `parent_context_id` is read by the frontend (`SessionSidebar.tsx` checks it in `isRoot()` and `subSessionCount()`) but is **never populated** by any agent or backend code today. + +### 1.2 New Metadata Fields + +All new session orchestration state lives in `metadata`. No schema migration is needed -- `metadata` is a JSON column. + +| Field | Type | When Set | Description | +|-------|------|----------|-------------| +| `parent_context_id` | `string` | Child creation | Context ID of the parent session. `null` for root sessions. | +| `session_type` | `enum` | Session creation | One of: `"root"`, `"child"`, `"passover"`. Default `"root"`. | +| `passover_from` | `string` | Passover creation | Context ID of the predecessor session (the one being replaced). Only set when `session_type = "passover"`. | +| `passover_to` | `string` | Passover execution | Context ID of the successor session. Set on the old session when passover completes. Forms a forward pointer in the linked list. | +| `passover_summary` | `object` | Passover creation | Structured summary carried to the new session. See Section 3.3. | +| `milestone` | `string` | Milestone reached | Name of the current/last milestone (e.g., `"tests-passing"`, `"pr-ready"`). | +| `auto_approve_remaining` | `integer` | User action | Number of remaining auto-approved passovers/milestones. Decremented on each auto-approval. When `0` or absent, HITL is required. | + +### 1.3 Context ID Generation + +Context IDs are generated as truncated UUIDs (`uuid4().hex[:36]`), matching the A2A SDK's `VARCHAR(36)` constraint. The generation happens: + +- **Root sessions**: Generated by the frontend (`SandboxPage.tsx`) or the backend chat proxy (`sandbox.py`) when `session_id` is not provided. +- **Child sessions**: Generated by the agent when it spawns a sub-agent via the delegate tool. +- **Passover sessions**: Generated by the agent (or backend) during the passover process. + +### 1.4 Session Lifecycle States + +Sessions use the existing `status.state` field from the A2A SDK: + +``` +submitted -> working -> completed + -> failed + -> canceled + -> input_required (HITL pause) +``` + +The new state relevant to orchestration is `input_required`, which the A2A spec already defines. When an agent hits a milestone and requires human approval, it sets `status.state = "input_required"` with a structured message. + +--- + +## 2. Parent-Child Session Creation + +### 2.1 When Children Are Created + +A child session is created when: + +1. **Main agent delegates to a sub-agent** via the `delegate` tool (out-of-process, separate A2A session) +2. **Main agent spawns an explore sub-agent** that needs its own persistent context (rare -- most explore tasks are ephemeral) + +In-process sub-agents (LangGraph sub-graphs running as asyncio tasks in the same pod) do **not** create child sessions. They share the parent's `context_id` and checkpoint. + +### 2.2 Agent-Side: Delegate Tool + +The `delegate` tool (currently a placeholder in the codebase) will be updated to: + +1. Generate a new `context_id` for the child session +2. Include `parent_context_id` and `session_type` in the A2A message metadata +3. Send the A2A `message/send` request to the target agent + +The A2A message metadata flows through the SDK into the `tasks` table automatically: + +``` +A2A message params: + message: + contextId: + metadata: + parent_context_id: + session_type: "child" + agent_name: "sandbox-legion" + title: "Sub-task: analyze test failures" +``` + +The A2A SDK's `DatabaseTaskStore` stores whatever metadata the message carries. No backend changes are needed -- the SDK already persists `metadata` as-is. + +### 2.3 Hierarchy Depth + +The design supports arbitrary depth (root -> child -> grandchild) but the first iteration limits display to **two levels** (root + children). Deeper hierarchies are flattened in the sidebar -- grandchildren appear as children of the root. + +This avoids UI complexity while still tracking the full lineage in the data model. + +### 2.4 Frontend: Sidebar Tree View + +The `SessionSidebar.tsx` component already has the building blocks: + +- `isRoot()` checks `!meta?.parent_context_id` -- works as-is +- `subSessionCount()` counts children by `parent_context_id` -- works as-is +- `rootOnly` toggle filters to root sessions -- works as-is + +Changes needed for tree view: + +1. **Indent child sessions** under their parent (16px left padding per level) +2. **Collapse/expand** toggle on parent sessions with children +3. **Sort children** by creation timestamp under their parent +4. **Session type badge**: Small icon or label distinguishing "child" from "passover" sessions + +The sidebar currently shows a flat list filtered by `rootOnly`. The tree view groups children under their parent when `rootOnly` is off, or hides them entirely when `rootOnly` is on (current behavior, no change needed). + +--- + +## 3. Automated Session Passover + +### 3.1 The Problem: Context Rot + +LLM context windows have a fixed size. As a session grows (tool call outputs, conversation history, checkpoint state), the model's ability to reason degrades. Today, the human operator detects this manually and writes a passover document. This is unsustainable for autonomous operation. + +### 3.2 Passover Trigger + +The agent monitors its own context consumption. The trigger is **token count exceeding a threshold** (configurable, default 80% of the model's context window). + +Where the check runs: + +- **Agent-side** (preferred): The agent's graph runner counts tokens in the LangGraph checkpoint after each turn. If the count exceeds the threshold, the agent initiates passover before processing the next user message. +- **Backend-side** (fallback): The backend chat proxy could estimate token count from the `history` JSON length, but this is less accurate and harder to act on. + +The first iteration uses the agent-side approach. The agent adds a `context_monitor` node to its LangGraph graph that runs after each tool invocation cycle: + +``` +check tokens in checkpoint + -> if below threshold: continue normally + -> if above threshold: generate passover summary, create new session, interrupt +``` + +### 3.3 Passover Summary Format + +The passover summary is a structured object stored in the new session's `metadata.passover_summary`: + +```json +{ + "generated_at": "2026-02-27T14:30:00Z", + "source_context_id": "abc123def456", + "token_count_at_passover": 185000, + "what_was_done": [ + "Cloned kagenti/kagenti repo and set up workspace", + "Fixed failing test in test_sandbox_legion.py (missing import)", + "Created PR #751 with the fix" + ], + "current_state": { + "working_directory": "/workspace/ctx-abc123/repos/kagenti", + "branch": "fix/test-import", + "open_files": [], + "pr_number": 751 + }, + "open_questions": [ + "PR CI is still running -- need to check results" + ], + "next_tasks": [ + "Check PR #751 CI status", + "If CI passes, request review from maintainers", + "If CI fails, investigate and fix" + ], + "key_decisions": [ + "Used uuid4 for session IDs instead of sequential integers" + ] +} +``` + +This mirrors the structure of the manual passover documents in `docs/plans/*passover*.md` but in machine-readable JSON. + +### 3.4 Passover Process + +Step-by-step: + +1. **Agent detects threshold**: The `context_monitor` node fires after a tool cycle and finds tokens > 80% of context window. + +2. **Agent generates summary**: The agent uses an LLM call to summarize the current session into the passover format (Section 3.3). This call uses a fresh, minimal context -- just the last N messages and the current state -- to avoid the very context rot problem we are solving. + +3. **Agent creates new session**: The agent (or backend, via an API call) creates a new task in the `tasks` table with: + - A new `context_id` + - `metadata.session_type = "passover"` + - `metadata.passover_from = ` + - `metadata.passover_summary = ` + - `metadata.parent_context_id = ` (preserves hierarchy -- a passover of a child is still a child) + - `metadata.agent_name` and `metadata.title` carried forward + +4. **Old session updated**: The old session's metadata gets: + - `metadata.passover_to = ` + - `status.state = "completed"` + - `status.message` includes a text note: "Session passed over to " + +5. **New session seeded**: The new session's first message (in `history`) is the passover summary rendered as markdown. The agent then continues working from where it left off, but with a clean context window. + +6. **Workspace preserved**: The new session uses the **same workspace directory** on the PVC (same `/workspace/ctx-/` path). The `context_id` changes for LangGraph checkpointing purposes, but the filesystem workspace is keyed to the original root context. This avoids re-cloning repos or re-installing packages. + +### 3.5 Passover Chain + +Passovers form a singly-linked list via `passover_from` and `passover_to`: + +``` +Session A (root) + passover_to: B + status: completed + +Session B (passover) + passover_from: A + passover_to: C + status: completed + +Session C (passover) + passover_from: B + passover_to: null + status: working <-- current active session +``` + +The chain is traversable in both directions: +- Forward: follow `passover_to` from any session +- Backward: follow `passover_from` from any session + +### 3.6 Manual Passover + +In addition to the automated trigger, users can manually request a passover via: + +- **UI button**: "Passover Session" in the session actions menu +- **API endpoint**: `POST /{namespace}/sessions/{context_id}/passover` + +This sends a special A2A message to the agent instructing it to generate a passover summary and create a new session immediately, regardless of context window usage. + +--- + +## 4. HITL Milestones + +### 4.1 Concept + +A milestone is a meaningful checkpoint in an agent's work where human review adds value. Examples: + +| Milestone | When | Why pause | +|-----------|------|-----------| +| `deploy-complete` | Agent finished deploying to a cluster | Human verifies deployment looks correct | +| `tests-passing` | All E2E tests pass | Human reviews test output before proceeding | +| `pr-ready` | Agent created a PR | Human reviews PR before merge | +| `destructive-action` | Agent wants to run a destructive operation | Human approves specific dangerous action | +| `cost-threshold` | Agent's LLM usage exceeds a dollar threshold | Human decides whether to continue spending | + +### 4.2 Milestone Definition + +Milestones are defined in the agent's configuration, not hardcoded. The agent's system prompt or a `milestones.json` config file lists the milestones: + +```json +{ + "milestones": [ + { + "name": "tests-passing", + "description": "All E2E tests pass", + "pause": true + }, + { + "name": "pr-ready", + "description": "Pull request created and ready for review", + "pause": true + }, + { + "name": "deploy-complete", + "description": "Deployment to target cluster completed", + "pause": false + } + ] +} +``` + +Milestones with `pause: true` trigger HITL. Milestones with `pause: false` are recorded in metadata for tracking but do not interrupt the agent. + +### 4.3 Agent-Side: Reaching a Milestone + +When the agent determines it has reached a milestone (via its own reasoning or explicit tool output), it: + +1. Updates the task's `metadata.milestone` to the milestone name +2. Sets `status.state = "input_required"` (A2A spec) +3. Sets `status.message` to a structured message describing the milestone: + +```json +{ + "role": "agent", + "parts": [ + { + "kind": "data", + "type": "milestone", + "name": "tests-passing", + "description": "All 47 E2E tests pass. Ready to proceed to PR creation.", + "options": ["approve", "deny", "skip-to-pr"], + "details": { + "test_count": 47, + "pass_count": 47, + "fail_count": 0, + "log_path": "/tmp/kagenti/tdd/test-run.log" + } + } + ] +} +``` + +In LangGraph terms, the agent calls `interrupt()` which suspends the graph. The graph can only be resumed when the human sends a response message. + +### 4.4 Integration with Existing HITL Module + +The `deployments/sandbox/hitl.py` module already defines `ApprovalRequest`, `ApprovalDecision`, `ContextRegistry`, and channel adapters (GitHub, Slack, Kagenti UI). Milestones integrate with this system: + +- A milestone triggers an `ApprovalRequest` with `risk_level` derived from the milestone type +- The `KagentiUIAdapter` posts the request to the UI via the existing status update SSE stream +- The human's response flows back as an `ApprovalDecision` +- The agent's `interrupt()` resumes with the decision + +The key difference from ad-hoc HITL requests is that milestones are **predefined and predictable**. The UI can show a milestone progress bar, and auto-approve can be applied to them. + +### 4.5 Frontend: Milestone Cards + +When the SSE stream delivers a status update with `state: "input_required"` and a milestone data part, the chat UI renders a **milestone card**: + +``` ++--------------------------------------------------+ +| MILESTONE: Tests Passing | +| | +| All 47 E2E tests pass. Ready to proceed to PR. | +| | +| [ Approve ] [ Deny ] [ Skip to PR ] | ++--------------------------------------------------+ +``` + +Clicking a button sends a message back to the agent's A2A endpoint with the chosen option. The backend's chat proxy (`sandbox.py`) forwards this as a regular A2A `message/send`, which resumes the LangGraph interrupt. + +--- + +## 5. Auto-Approve + +### 5.1 Concept + +Auto-approve lets the human pre-authorize the agent to pass through the next N milestones or passovers without stopping. This is useful for: + +- Overnight runs where the human wants the agent to make progress but not run indefinitely +- Known-good sequences (e.g., "the next 3 milestones are routine, approve them all") +- Passover chains where the human trusts the agent to manage its own context window + +### 5.2 Mechanism + +The `auto_approve_remaining` field in session metadata is a simple counter: + +1. **Human sets counter**: Via API or UI, the human sets `auto_approve_remaining: N` on the current session. + +2. **Agent reaches milestone or passover**: Instead of setting `status.state = "input_required"`, the agent checks the counter: + - If `auto_approve_remaining > 0`: decrement the counter, log the auto-approval, continue working. + - If `auto_approve_remaining == 0` or absent: pause for HITL as normal. + +3. **Counter carries across passovers**: When a passover creates a new session, the remaining counter transfers to the new session's metadata (decremented by 1 for the passover itself). + +4. **Counter is per-session**: Each session tracks its own counter. Setting auto-approve on a parent does not affect children. + +### 5.3 Safety Rails + +- **Maximum cap**: `auto_approve_remaining` cannot exceed 20 (server-side validation). This prevents runaway autonomous operation. +- **Destructive milestones bypass auto-approve**: Milestones with `risk_level: "critical"` (e.g., `destructive-action`) always require human approval regardless of the counter. +- **Cost ceiling**: If the agent's cumulative LLM cost exceeds a configured threshold, auto-approve is suspended and HITL is required. +- **Audit trail**: Every auto-approved milestone or passover is logged in the session history with `"auto_approved": true`, so the human can review what was skipped. + +### 5.4 Frontend: Auto-Approve Controls + +The session configuration panel (accessible from the session sidebar or chat header) shows: + +- **Auto-approve toggle**: On/off switch +- **Remaining count**: Editable number field (1-20) +- **Badge in sidebar**: When auto-approve is active, the session shows a small badge: "Auto (3 remaining)" + +### 5.5 API + +``` +PUT /{namespace}/sessions/{context_id}/auto-approve +Body: { "count": 5 } +Response: { "auto_approve_remaining": 5 } +``` + +Validation: +- `count` must be between 0 and 20 +- Setting `count: 0` disables auto-approve +- Returns 404 if session does not exist + +--- + +## 6.

Agent-Side Changes + +### 8.1 Context Monitor Node + +A new LangGraph node added to the agent's graph that runs after each tool invocation cycle: + +``` +graph flow: + user_input -> agent_reasoning -> tool_execution -> context_monitor -> agent_reasoning + ^ | + | (if under | + | threshold) | + +------------------+ + + (if over threshold) -> passover_node -> END +``` + +The `context_monitor` node: +1. Counts tokens in the current checkpoint (messages + tool outputs) +2. Compares against the configured threshold (default: 80% of model context window) +3. If under threshold: routes back to `agent_reasoning` (normal flow) +4. If over threshold: routes to `passover_node` + +### 8.2 Passover Node + +The `passover_node`: +1. Calls the LLM with a focused prompt to generate the passover summary +2. Creates a new A2A task via the backend API (or directly in the DB if co-located) +3.

Continuing in new session ." + +### 8.3 Milestone Node + +When the agent detects a milestone condition (via tool output analysis or explicit milestone tool), it: +1. Checks `auto_approve_remaining` in its current task metadata +2. If auto-approve available: decrements counter, logs, continues +3. If no auto-approve: calls LangGraph `interrupt()` with milestone data + +### 8.4 Delegate Tool Update + +The `make_delegate_tool()` function (currently a placeholder) will be implemented to: +1.

Poll for completion or stream results back + +--- + +## 9. Implementation Plan + +### Phase 1: Parent-Child Hierarchy (P0) + +**Goal**: Child sessions appear under parents in the sidebar. + +1. Update `delegate` tool to populate `parent_context_id` and `session_type` in A2A messages +2. Update `SessionSidebar.tsx` to indent child sessions under parents +3. Add collapse/expand toggle for parent sessions +4. Verify `isRoot()` and `subSessionCount()` work correctly (they should, no changes needed) + +**Effort**: ~2 days +**Testing**: Deploy agent, create a delegation, verify sidebar shows tree structure. + +### Phase 2: Automated Passover (P0) + +**Goal**: Agent autonomously creates new sessions when context grows large. + +1. Add `context_monitor` node to agent's LangGraph graph +2. Implement `passover_node` with summary generation +3. Add `POST /{namespace}/sessions/{context_id}/passover` backend endpoint +4. Add `GET /{namespace}/sessions/{context_id}/chain` backend endpoint +5. Add passover notice banner in `SandboxPage.tsx` +6. Add passover chain view + +**Effort**: ~4 days +**Testing**: Send enough messages to trigger passover, verify new session is created with summary, verify chain API returns correct data. + +### Phase 3: HITL Milestones (P1) + +**Goal**: Agent pauses at milestones for human approval. + +1. Add milestone node to agent's LangGraph graph +2. Integrate with existing `hitl.py` module +3. Add milestone card rendering in `SandboxPage.tsx` +4. Handle milestone response (approve/deny) via A2A message flow + +**Effort**: ~3 days +**Testing**: Configure milestone, trigger it, verify UI shows approval card, approve and verify agent continues. + +### Phase 4: Auto-Approve (P2) + +**Goal**: Humans can pre-approve N passovers/milestones. + +1. Add `PUT /{namespace}/sessions/{context_id}/auto-approve` endpoint +2. Add auto-approve check in agent's milestone and passover nodes +3. Add auto-approve controls in UI session config +4. Add auto-approve badge in sidebar + +**Effort**: ~2 days +**Testing**: Set auto-approve to 3, trigger 4 milestones, verify first 3 auto-approved and 4th pauses. + +--- + +## 10. What This Design Does NOT Cover + +These are explicitly out of scope for the first iteration: + +- **Cross-agent session orchestration**: This design covers single-agent session management. Multi-agent orchestration (agent A delegates to agent B which delegates to agent C) is a separate concern. +- **Session forking**: Creating two child sessions from the same parent that run in parallel. The data model supports this but the UI and agent logic do not. +- **Session merging**: Combining results from multiple child sessions back into a parent. This requires a separate aggregation design. +- **Persistent workspace migration**: When a passover happens, the workspace stays on the same PVC path. Cross-cluster or cross-namespace passover is not supported. +- **Token counting accuracy**: The first iteration uses a heuristic (character count / 4) for token estimation. Accurate tokenizer-based counting can be added later. +- **Passover across agent types**: Passing over from a LangGraph agent to a CrewAI agent. Both ends must speak the same A2A protocol, but checkpoint format differs. + +--- + +## 11. Key Design Decisions + +| Decision | Rationale | +|----------|-----------| +| All orchestration state in `metadata` JSON | No schema migration needed. The A2A SDK stores `metadata` as opaque JSON. Adding fields is a non-breaking change. | +| Agent-side passover trigger (not backend) | The agent has direct access to LangGraph checkpoint token counts. The backend would need to estimate from history JSON, which is less accurate. | +| Passover creates a new `context_id` but keeps the same workspace | LangGraph checkpoints are keyed by `thread_id` (= `context_id`). A new context gets a fresh checkpoint (clean context window) while the workspace files persist. | +| Auto-approve counter, not time-based | A counter is deterministic and auditable. "Auto-approve for the next 2 hours" is ambiguous -- does it include milestones at hour 1:59 that take 30 minutes to complete? | +| Maximum 20 auto-approves | Safety cap. An agent with 20 auto-approved milestones can run unattended for a long time but not indefinitely. Critical milestones always require human approval. | +| Two-level display in sidebar | Deeply nested trees are hard to navigate in a 280px sidebar. Grandchildren appear as children of the root, which is sufficient for the delegation patterns we support. | + +--- + +## 12.

Legacy types +(`llm_response` reused for all nodes) are still emitted for backward +compatibility but the frontend SSE handler deduplicates: when a typed event +is received, any legacy event with the same `loop_id` and content is skipped. + +### Historical Reconstruction + +Agent loop events are persisted for history reload: + +1. **Persistence:** The `loop_events` list is stored in task metadata via an + atomic write in a `finally` block, ensuring events are saved even on error. + +2. **History endpoint:** The backend history endpoint returns the `loop_events` + array from task metadata alongside the existing message history. + +3. **Frontend reconstruction:** On session reload, the frontend iterates through + `loop_events` and reconstructs `AgentLoop` objects using the same state + reducer that the SSE handler uses. This ensures historical and live views + produce identical UI state. + +### Known Issue: Streaming vs Historical Consistency + +A consistency test validates that the `AgentLoop` objects produced by the SSE +streaming handler match those reconstructed from persisted `loop_events`. Any +mismatch indicates a bug in either the serializer or the reconstruction logic. + +The reconstruction loop and the SSE handler **must** produce identical +`AgentLoop` objects. Divergence causes visual inconsistencies between live +sessions and reloaded history (e.g., missing steps, wrong token counts, or +status stuck on "executing"). + +### Model Switcher + +A cog icon in the session header opens a popover with a model dropdown. The +selected model is stored as `sessionModelOverride` state in `SandboxPage.tsx`. +When set, the override is sent with each chat request to the backend, which +proxies available models from the LiteLLM `/models` endpoint. + +The model list is fetched once on session load and cached. The current model +is displayed in the `ModelBadge` component in the summary bar. + +### HITL Approval Card + +`HitlApprovalCard.tsx` replaces the raw text rendering of HITL checkpoint +events. It displays: + +- Progress summary (e.g., "Completed 3/5 plan steps") +- Budget consumption (tokens, iterations, wall clock) +- **Approve** button — resumes the graph +- **Deny** button — routes to reporter with partial results + +The card appears inline in the chat flow and disables its buttons once a +decision is made (or after the 5-minute auto-continue timeout). + +### Sub-sessions Tab + +`SubSessionsPanel.tsx` renders a tab showing child sessions created by the +`delegate` tool (Legion variant). Each child session row shows: + +- Task description +- Status (running / done / failed) +- Model used +- Token count + +Rows are clickable and navigate to the child session's chat view. + +### Compact Sidecar Panel + +For sidecar deployment mode, the agent loop renders as an accordion with +compact rows instead of the full `AgentLoopCard`. The `Looper` component +shows iteration progress as `2/5` with a mini progress bar, providing +at-a-glance status without consuming full chat panel width. diff --git a/docs/plans/2026-03-03-sandbox-reasoning-loop-design.md b/docs/plans/2026-03-03-sandbox-reasoning-loop-design.md new file mode 100644 index 000000000..f2885d14b --- /dev/null +++ b/docs/plans/2026-03-03-sandbox-reasoning-loop-design.md @@ -0,0 +1,404 @@ +# Sandbox Agent Reasoning Loop Design + +> **Date:** 2026-03-03 +> **Author:** Session G +> **Status:** Approved +> **Depends on:** Section 9 of sandbox-platform-design.md (Legion delegation) + +## Current State (as of Session G) + +The sandbox agent container image ALREADY has a LangGraph graph +(`/app/src/sandbox_agent/graph.py`) with: +- ✅ 6 tools (shell, file_read, file_write, web_fetch, explore, delegate) +- ✅ Tool binding via `llm.bind_tools(tools)` + `ToolNode` + `tools_condition` +- ✅ State: `SandboxState(MessagesState)` with context_id, workspace, final_answer +- ✅ HITL via `interrupt()` in shell tool +- ✅ PostgreSQL checkpointer for state persistence +- ✅ Streaming via `graph.astream(stream_mode="updates")` + +The `deployments/sandbox/agent_server.py` file is a SEPARATE simpler server +that uses raw `litellm.completion()` — it's NOT the A2A agent.

The frontend uses per-step token counts for the step headers +and aggregates them for the summary bar. + +### request_id Capture + +The agent captures the LiteLLM `request_id` from each completion response and +stores it in task metadata as `llm_request_ids` (an append-only list): + +```python +request_id = response.response_metadata.get("request_id") +if request_id: + task_metadata["llm_request_ids"].append(request_id) +``` + +This enables end-to-end tracing from UI event back to the LLM provider request. + +### Budget Update + +Session S tightened the budget defaults: + +| Parameter | Old value | New value | Reason | +|-----------|-----------|-----------|--------| +| `max_outer_iterations` | 10 | **6** | Prevents runaway loops; reflector forces `done` when exceeded | + +When the reflector detects `iteration >= max_iterations`, it sets +`decision = "done"` regardless of task completion status and the reporter +generates a partial report with results gathered so far. + +### Known Issue: "continue" as Final Answer + +When the budget forces termination, the reflector's decision string (e.g., +`"continue"`) can leak into the reporter's input, causing the final answer to +contain the literal word "continue" instead of a synthesized report. This happens +because the reflector emits its decision to the message history before the +budget check overrides it to `"done"`. The reporter then sees both the decision +message and the override. + +**Workaround:** Not yet resolved. Requires the budget-forced `done` path to +strip or replace the reflector's last message before invoking the reporter. diff --git a/docs/plans/2026-03-04-platform-agent-runtime-design.md b/docs/plans/2026-03-04-platform-agent-runtime-design.md new file mode 100644 index 000000000..64459f70d --- /dev/null +++ b/docs/plans/2026-03-04-platform-agent-runtime-design.md @@ -0,0 +1,1088 @@ +# Platform-Owned Agent Runtime — Design & Architecture + +> **Date:** 2026-03-04 (design), 2026-03-09 (current) +> **Status:** Implemented (core), In Progress (sidecars, historical consistency) +> **PR:** #758 (feat/sandbox-agent) + +## 1.

The deployment +name is self-documenting and reflects active layers +(e.g., `sandbox-legion-secctx-landlock-proxy`). + +## 10. MAAS Model Compatibility + +Tested 2026-03-03 on Red Hat AI Services: + +| Model | tool_choice=auto | Recommended For | +|-------|:----------------:|-----------------| +| **Llama 4 Scout 17B-16E** (109B MoE) | 10/10 | Tool-calling agents (default) | +| Mistral Small 3.1 24B | 0/10 | Chat-only (no structured tool_calls with auto) | +| DeepSeek R1 Qwen 14B | No | Reasoning tasks (no tool support) | +| Llama 3.2 3B | No | Too small for function calling | + +All clusters use **Llama 4 Scout** for sandbox agents, routed through +LiteLLM proxy. + +## 11. Streaming and Chat Architecture + +The platform uses a hybrid streaming architecture: real-time SSE during active +requests, with polling fallback for idle sessions. + +### SSE Streaming (active requests) + +The `POST /chat/stream` endpoint opens a request-scoped SSE connection that +remains active for the duration of the agent's A2A response. The backend SSE +proxy (`_proxy_agent_sse` in `sandbox.py`) performs several transformations: + +1. **Parses JSON lines** from the agent's raw SSE stream +2. **Detects `loop_id`** fields and wraps events in `loop_event` envelopes +3. **Forwards events** to the frontend in real-time +4. **Captures loop events** for persistence (new-type events only, excluding + legacy `llm_response` duplicates) + +The SSE connection closes when the agent completes or errors. There is no +persistent SSE connection per session. + +### Polling Fallback (idle sessions) + +A 5-second `setInterval` in `SandboxPage.tsx` polls +`GET /sessions/{id}/history` with `limit: 5` when: +- A `contextId` is set (session is active) +- `isStreaming` is false (no active SSE connection) + +Polling deduplicates messages by their `_index` field. + +### Historical Load + +`GET /sessions/{id}/history` supports pagination via `limit` and `offset` +parameters. It returns message history from the tasks table alongside +`loop_events` from task metadata, enabling full frontend reconstruction +of AgentLoopCard components on session reload. + +### Loop Event Persistence + +Loop events are persisted to task metadata in a `finally` block within the +SSE proxy generator. This atomic write ensures events are saved even if the +stream is interrupted. The persistence combines agent name metadata and +loop events into a single DB update to avoid race conditions. + +### Frontend Reconstruction + +On session reload, the frontend iterates persisted `loop_events` from the +history response and reconstructs `AgentLoop` objects using the same state +reducer as the live SSE handler. This enables AgentLoopCard rendering for +historical sessions. + +### Future: WebSocket Upgrade + +A WebSocket design exists for multi-user session updates and delegation +callbacks. See [WebSocket / SSE Session Updates Design](2026-03-06-websocket-session-updates-design.md). + +## 12. Event Pipeline + +The agent event pipeline provides typed, structured events from graph nodes +through to the frontend. + +### Pipeline stages + +``` +Agent graph node (planner, executor, reflector, reporter) + -> event_serializer.py (LangGraphSerializer) + -> Backend SSE proxy (sandbox.py: _proxy_agent_sse) + -> Frontend SSE handler (SandboxPage.tsx) + -> AgentLoop state reducer + -> AgentLoopCard render +``` + +### Event types + +The `LangGraphSerializer` emits distinct event types per graph node: + +| Graph Node | Event Type(s) | Content | +|------------|---------------|---------| +| `planner` | `plan` | Plan steps array, iteration number, reasoning text | +| `executor` | `plan_step`, `tool_call`, `tool_result` | Step index, tool invocations, tool outputs | +| `reflector` | `reflection` | Done flag, current step, assessment text | +| `reporter` | `llm_response` (with `loop_id`) | Final answer text | +| (any node) | `budget_update` | Token usage, wall clock time | +| (HITL) | `hitl_request` | Command needing approval, reason | + +### Legacy compatibility + +Legacy event types (`llm_response` for all nodes) are still emitted for backward +compatibility. The frontend deduplicates: when typed events with `loop_id` are +present, flat events are suppressed entirely via the `session_has_loops` flag +in the SSE proxy. + +### Backend SSE proxy behavior + +The proxy in `sandbox.py` performs line-by-line JSON parsing of the agent's +status messages. For each parsed event: +- If it contains a `loop_id`, it wraps the event in a `loop_event` envelope +- New-type events (non-legacy) are accumulated in a `loop_events` list +- Legacy types (`llm_response`, `tool_call`, `tool_result` without `loop_id`) + are passed through only if no loop events have been seen in the session + +### Persistence + +Only new-type events are persisted to task metadata. The `loop_events` list +is written via an atomic `UPDATE tasks SET metadata = ...` in the SSE proxy's +`finally` block, merged with existing metadata (agent name, visibility) to +prevent overwrites. + +## 13. Sidecar Agents + +Sidecar agents are **in-process asyncio tasks** (not separate Kubernetes pods) +that run alongside sandbox sessions. They observe parent session events and +can intervene when problems are detected. + +### Architecture + +The `SidecarManager` (singleton in `kagenti/backend/app/services/sidecar_manager.py`) +manages sidecar lifecycle: + +- **Registry:** `Dict[parent_context_id, Dict[SidecarType, SidecarHandle]]` +- **Event queues:** Per-session `asyncio.Queue` (maxsize 1000), filled by `fan_out_event()` +- **Lifecycle:** `enable()` spawns an `asyncio.Task`, `disable()` cancels it, `cleanup_session()` tears down all sidecars for a session + +### Sidecar types + +| Sidecar | Analyzer | Behavior | +|---------|----------|----------| +| **Looper** | `LooperAnalyzer` | Auto-continue kicker. Drains event queue, checks if agent turn completed, sends "continue" via A2A. Respects configurable counter limit; when limit reached, emits HITL observation or auto-resets (if `auto_approve` is true). | +| **Hallucination Observer** | `HallucinationAnalyzer` | SSE-driven. Validates file paths and API references in agent output against the workspace filesystem. Emits observations when suspect paths are detected. | +| **Context Guardian** | `ContextGuardianAnalyzer` | SSE-driven. Tracks token usage trajectory against configurable thresholds (`warn_threshold_pct`, `critical_threshold_pct`). Emits warning/critical observations and can trigger HITL approval for intervention. | + +### Looper auto-continue mechanism + +When the looper decides to auto-continue, it creates a **child session** via +A2A `message/send` with a new `context_id` and `parent_context_id` in metadata. +This keeps iterations visible in the sub-sessions panel without polluting the +parent session's context. The looper retries metadata writes (up to 5 attempts) +because the task row may not exist immediately after the A2A call. + +### REST API + +The sidecar REST API (`/sandbox/{namespace}/sessions/{context_id}/sidecars/...`) +provides endpoints for: +- `GET .../sidecars` -- list all sidecars for a session +- `POST .../sidecars/{type}/enable` -- spawn sidecar task +- `POST .../sidecars/{type}/disable` -- cancel sidecar task +- `PUT .../sidecars/{type}/config` -- hot-reload config +- `POST .../sidecars/{type}/reset` -- disable + re-enable (fresh analyzer) +- `GET .../sidecars/{type}/observations` -- SSE stream of observations +- `POST .../sidecars/{type}/approve/{msg_id}` -- approve HITL intervention +- `POST .../sidecars/{type}/deny/{msg_id}` -- deny HITL intervention + +### UI + +Compact accordion panel with per-sidecar tabs, enable/disable toggles, +auto-approve/HITL switches, and observation streams. The looper shows +iteration progress as `2/5` with a mini progress bar. + +### Known issues + +- Looper auto-continue is non-functional: SSE observations endpoint returns + 401 (auth not forwarded to sidecar SSE endpoint), and `fan_out_event` is + not reliably triggering the looper's event queue +- A2A message injection (corrective messages into parent session) is stubbed + (`approve_intervention` logs but does not inject) +- Heartbeat observations needed for test verification + +## 14. Agent Loop UI + +The agent loop UI renders structured reasoning events as expandable cards +instead of flat chat bubbles. + +### AgentLoopCard + +Each agent response renders as a single `AgentLoopCard`: +- **Final answer** (markdown) always visible at top +- **"Show reasoning" toggle** expands `LoopSummaryBar` + `LoopDetail` +- During streaming: auto-expanded (live progress). After completion: auto-collapsed. +- On history reload: all collapsed. + +### LoopSummaryBar + +Single-row summary displaying: +- Status icon (spinner during execution, check/cross on completion) +- Tool count, token count (formatted as "1.2k"), status text +- `ModelBadge` showing the LLM model used +- Duration in seconds +- Expand/collapse toggle + +### Node type styling + +Steps within the `LoopDetail` carry visual badges by event type: + +| Event Type | Node | Color | +|------------|------|-------| +| `planner_output` | Planner | Blue | +| `executor_step` | Executor | Green | +| `reflector_decision` | Reflector | Orange | +| `reporter_output` | Reporter | Purple | + +### Per-step token display + +Each `AgentLoopStep` carries `tokens: { prompt, completion }` for per-step +token accounting. The `LoopSummaryBar` sums tokens across all steps and +displays the total alongside a `ModelBadge`. + +### HITL approval + +When the agent emits a `hitl_request` event, the `HitlApprovalCard` component +renders an interactive card with the command needing approval, the reason, and +Approve/Deny buttons. Once actioned, buttons are replaced with a status label. + +## 15. Session Management + +### Agent name resolution + +`_resolve_agent_name()` in `sandbox.py` is the **single source of truth** for +determining which agent owns a session. For new sessions (no existing +`session_id`), it uses the `request_agent` field. For existing sessions, it +queries the tasks table for the DB-bound agent name, ensuring sessions remain +pinned to their original agent even if the request specifies a different one. + +### Metadata merge + +Session metadata is written atomically via a JSON merge pattern: the SSE proxy's +`finally` block reads existing metadata, merges in new fields (`agent_name`, +`visibility`, `loop_events`), and writes back in a single `UPDATE`. This prevents +race conditions between `_set_owner_metadata()` and loop event persistence. + +### Sub-sessions + +Delegation and looper auto-continue create child sessions with +`parent_context_id` in their task metadata. The `SubSessionsPanel` component +queries for child sessions via `getChildSessions(namespace, contextId)` and +renders them with status badges (green=completed, blue=working, red=failed). +Clicking a child session navigates to it. + +## 16. LiteLLM Integration + +LiteLLM proxy serves as the model routing layer for all sandbox agents. + +### Model proxy + +`GET /api/v1/models` (in `models.py`) proxies the LiteLLM `/models` endpoint +with a 5-minute in-memory cache. Returns an OpenAI-compatible list of available +model IDs. + +### Token usage + +`GET /api/v1/token-usage/sessions/{id}` (in `token_usage.py`) queries LiteLLM's +`/spend/logs` endpoint by `request_id`. Request IDs are stored in session task +metadata as `llm_request_ids`. The endpoint aggregates spend per model and +returns prompt/completion token counts and cost. + +`GET /api/v1/token-usage/sessions/{id}/tree` extends this to session trees: +it queries child sessions (by `parent_context_id` in metadata) and merges +their usage into an aggregate. + +### Model switcher + +The `ModelSwitcher` component renders as a cog icon popover in the session +header. It fetches available models from the models API, displays them in a +`Select` dropdown, and fires `onModelChange` to apply a per-session model +override. + +### Helm configuration + +The backend reads `LITELLM_API_KEY` from a Kubernetes secret: +```yaml +- name: LITELLM_API_KEY + valueFrom: + secretKeyRef: + name: litellm-proxy-secret + key: master-key + optional: true +``` + +`LITELLM_BASE_URL` defaults to `http://litellm-proxy.kagenti-system.svc:4000`. + +## 17. Testing Architecture + +### E2E test suites + +The platform has 10 core E2E tests across 5 suites, executed in parallel with +4 Playwright workers (~1.5 minutes total): + +| Test File | Tests | Coverage | +|-----------|-------|----------| +| `sandbox-sessions.spec.ts` | 3 | Session isolation, state leak prevention, persistence across reload | +| `sandbox-walkthrough.spec.ts` | 1 | Full user journey (create, chat, tools, file browser) | +| `sandbox-variants.spec.ts` | 4 | Multi-turn with tool calls across all 4 agent variants (legion, hardened, basic, restricted) | +| `agent-rca-workflow.spec.ts` | 1 | RCA agent end-to-end with skill invocation and loop verification | +| `sandbox-delegation.spec.ts` | 1 | Delegate tool spawns child session, renders in sidebar | + +### Additional test suites + +| Test File | Purpose | Status | +|-----------|---------|--------| +| `agent-loop-consistency.spec.ts` | Validates streaming vs historical reconstruction match | In progress (known divergence on step 5 of root cause chain) | +| `agent-resilience.spec.ts` | Validates recovery after agent pod restart mid-request | Implemented | +| `sandbox-sidecars.spec.ts` | Sidecar agent lifecycle and observations | Implemented | +| `sandbox-hitl.spec.ts` | HITL approval workflow | Implemented | + +### Unit tests + +94 unit tests across the `deployments/sandbox/` directory cover sandbox profile +generation, skill pack loading, repo management, agent server, triggers, nono +launcher, TOFU verification, and entrypoint loading. + +### PatternFly testing workarounds + +Two patterns address PatternFly component limitations in Playwright: +- **`pressSequentially`** for `TextInput`: PatternFly's controlled inputs + require character-by-character input instead of `fill()` to trigger + React's change handlers correctly +- **`Promise.race`** for hangs: Some PatternFly interactions (particularly + dropdowns and popovers) can cause Playwright to hang waiting for + navigation; `Promise.race` with a timeout prevents test deadlocks + +## 18.

Known Failure Modes + +### 4.1 Format Error Crashes Agent (FIXED) + +**Symptom:** "Error: Replacement index 0 out of range for positional args tuple" +**Cause:** Executor prompt template contained literal `{...}` interpreted by `.format()`. +**Fix:** Escaped braces + `_safe_format()` wrapper. Fixed in build 47. + +### 4.2 Metadata Duplication Across Tasks (FIXED) + +**Symptom:** All tasks in a multi-turn session share the same `loop_events`. +**Cause:** `finally` block merged metadata from ALL task rows into the latest one. +**Fix:** `stream_task_id` tracks each stream's own DB row. Writes target `WHERE id = $2`. + +### 4.3 "Respond to the user" as Plan + +**Symptom:** Planner step shows trivial plan instead of real multi-step plan. +**Root causes (multiple):** +1. Agent's planner outputs single-step plan for simple requests (by design) +2. Last replan was overwriting `loop.plan` (fixed: now preserved as `replans`) +3. History reconstruction may process events in wrong order +4. `planner_output.steps` might contain different data than expected + +**Needs:** Logging at Stage 1 to see what `steps` the planner actually produces. + +### 4.4 Flat Text Instead of AgentLoopCards + +**Symptom:** Session shows raw text blocks instead of structured loop cards. +**Root causes (multiple):** +1. Backend's `_extract_text_from_parts()` returns text without `loop_id` +2. Agent emits plain text (not JSON lines) for some graph events +3. The JSON line doesn't parse correctly (truncated, malformed) +4. `status_message` contains non-JSON content mixed with JSON lines + +**Needs:** Logging at Stage 3 to see the raw `status_message` before parsing. + +### 4.5 Historical Loop Cards Missing Events + +**Symptom:** After reload, loop cards show fewer steps than during streaming. +**Cause:** Legacy types forwarded during streaming but not persisted. +**Fix:** Filter legacy at backend before forwarding (see Section 8). + +### 4.6 SSE Timeout Drops Events (FIXED) + +**Symptom:** RCA agent sessions lose events mid-stream. +**Cause:** Nginx `proxy_read_timeout 300s` kills idle connections. +**Fix:** 15s keepalive pings + event recovery from agent task store. + +--- + +## 5. Logging Strategy + +To diagnose rendering parity issues, add structured logging at every stage boundary.

Design Principles + +### P1: Single Source of Truth + +The `loop_events` array persisted in `task.metadata` IS the source of truth. Both streaming and history must produce the same `AgentLoop` state from the same events. + +**Rule:** If an event affects rendering, it MUST be in `loop_events`. No rendering logic should depend on transient SSE-only data. + +### P2: Idempotent Reconstruction + +`applyLoopEvent(loop, event) -> loop` must be a pure function. Given the same events, it produces the same `AgentLoop` regardless of incremental (streaming) or batch (history) application. + +**Rule:** Extract the loop-building logic into a shared function used by BOTH paths. + +### P3: No Legacy Types in Pipeline + +Legacy event types (`plan`, `plan_step`, `reflection`, `llm_response`) should be: +- Still emitted by serializer (backward compat with older frontends) +- Filtered OUT at the backend before forwarding (not just at persistence) +- Never processed by the current frontend + +**Rule:** Filter legacy types at the EARLIEST point (backend), not at every downstream stage. + +### P4: Per-Task Isolation + +Each user message creates one A2A task. Each task has its own `loop_events`. No cross-task merging. + +**Rule:** `stream_task_id` identifies this stream's DB row. All writes go to `WHERE id = stream_task_id`. + +### P5: Observable Pipeline + +Every stage transformation must be logged with `session_id` + `loop_id` for end-to-end correlation. + +**Rule:** A test failure should be diagnosable from logs alone, without reproducing. + +--- + +## 7.

Looper Not Working (CRITICAL) + +**Problem:** The looper sidecar is enabled but doesn't auto-continue the agent. + +**Three sub-issues:** + +**2a. SSE observations return 401** +The sidecar observation SSE endpoint requires auth, but the `EventSource` in `SidecarTab.tsx` doesn't pass auth headers. EventSource doesn't support custom headers natively — need to use `fetch` + SSE parsing or pass token as query param. + +**2b. fan_out_event not triggering auto-continue** +The `fan_out_event` call in `_stream_sandbox_response` (line ~1484) forwards SSE events to the sidecar manager. But the looper's `ingest()` method may not be detecting the `COMPLETED` state from the forwarded events. Check: +- Is `fan_out_event` being called? (add logging) +- Is the event format correct for `LooperAnalyzer.ingest()`? +- Is `should_kick()` returning `True`? +- Is the kick actually sending a "continue" message? + +**2c. Looper should create sub-sessions** +Currently the looper sends "continue" to the same session. It should: +- Create a child session (with `parent_context_id`) +- Share the parent's workspace +- Be visible in the sub-sessions tab + +**Key code locations:** +- Sidecar manager: `kagenti/backend/app/services/sidecar_manager.py` +- Looper analyzer: `kagenti/backend/app/services/sidecars/looper.py` +- fan_out_event: `sandbox.py` ~line 1484 +- SidecarTab SSE: `kagenti/ui-v2/src/components/SidecarTab.tsx` + +### 3. "continue" as Final Answer + +**Problem:** When the agent's budget is exhausted (6/6 iterations), the reflector forces `done=True` but its text output is just "continue". The reporter receives this as input and outputs "continue" as the final answer. + +**Fix approaches:** +- **Agent-side (preferred):** In `reporter_node` (`reasoning.py`), detect when input is a bare decision keyword and generate a summary from `step_results` instead +- **Frontend-side (band-aid, already applied):** Filter `reporter_output` content matching `/^(continue|replan|done|hitl)\s*$/` → set `finalAnswer = ''` + +**Key code:** `reasoning.py` ~line 604 (`reporter_node`) + +### 4. Empty Blocks in Agent Loop + +**Problem:** Some `executor_step` events have empty `description` — the executor emits a step event before the LLM responds, then another after. The first one creates an empty block. + +**Fix:** In the frontend SSE handler, when an `executor_step` arrives with the same step index as an existing step, UPDATE the existing step instead of creating a new one. Currently: +```typescript +steps: [ + ...l.steps.filter((s) => s.index !== le.step), // Already filters! + { index: le.step, description: le.description || '', ... } +] +``` +The filter removes the old step — but if `description` is empty, the replacement is also empty.

RCA Agent — Flaky (A2A SDK CancelledError) — ROOT CAUSE FOUND + +**Problem:** The A2A SDK's event queue gets `CancelledError` during long-running multi-iteration agents, dropping SSE events. The agent continues processing (our fix) but the backend receives fewer events → incomplete loop_events → old format in UI. + +**Root cause chain:** +1.

Sidecar Auto-Continue — Design Issue + +**Problem:** Looper polls DB for parent session state. After first auto-continue creates a child session, the parent's state stays COMPLETED. Looper needs to track and poll child context_ids. + +**Design:** Message queuing (next phase) — looper queues "continue" messages, picks them up when current loop finishes. + +### 3. File Browser 404 for Some Agents + +**Problem:** `/files/{agent_name}/{context_id}` returns 404 for sandbox-basic but works for rca-agent. May be a workspace path resolution issue per agent deployment. + +### 4. Reflector Loops Without Progress — Needs Stall Detection + +**Problem:** Session `8a6d778a` shows 52 messages — the agent called tools in iterations 1-2, then looped 25+ times (planner→executor→reflector) without any tool calls or new output. The reflector keeps saying "replan" without detecting that nothing changed. + +**Evidence:** 52 history messages, only 2 tool_results at messages 3 and 8, then 40+ planner/executor/reflector cycles with zero tool calls. + +**Fix:** Add stall detection to the reflector: +- Track tool_call count per iteration +- If last 3 iterations had 0 tool calls → force `done` +- Or: compare executor output across iterations — if identical, force `done` +- Consider reducing default budget back to a reasonable number (20?) with stall detection + +**Code location:** `reasoning.py` reflector_node — needs access to iteration history + +### 5. Executor Still Writes Text Instead of Tool Calls (Sometimes) + +**Problem:** Despite `tool_choice="any"`, Llama 4 Scout occasionally writes text descriptions instead of using function calling API. The `parse_text_tool_calls()` catches some patterns (Llama format, legacy format) but not all. + +**Fix:** Proper skill unpacking — when executor output contains a slash command, load the skill, extract commands, re-feed to planner. Don't hack the parser. + +### 5. Budget Not Configurable Per Session + +**Problem:** Budget (100 iter, 10 tools/step, 1M tokens) is hardcoded as defaults. Should be configurable per agent (env vars) and overridable per session (UI/API). + +### 6. Sidecar State Not Persisted + +**Problem:** Sidecar handles (enabled/disabled, config, observations) are stored in-memory in `SidecarManager._handles`. Backend restart loses all state. UI shows no sidecars after restart. + +**Fix:** Persist sidecar state in session metadata or a separate DB table. On startup, restore handles for active sessions. + +### 7. Multi-Turn Loop Events — Per-Task Isolation + +**Problem:** The metadata merge in `finally` block was copying loop_events across tasks. Fixed by excluding `loop_events` from merge, but older sessions still have duplicated data. + +**Status:** Fixed for new sessions. Old sessions show deduplicated events (may lose some turns). + +--- + +## Architecture Reference + +### Event Pipeline (Working) +``` +Agent graph node + → event_serializer.py (typed JSON with type + loop_id) + → A2A SSE stream (status-update with message parts) + → Backend _stream_sandbox_response: + -

Planner/executor/reflector/reporter events are NOT emitted with `loop_id` — they arrive as flat A2A task updates. The backend's `LOOP_FWD` logging confirms: only 1 event per session (type=router). + +**Root cause**: The agent's event serializer (`event_serializer.py`) emits the `router` event with `loop_id` but subsequent graph nodes (planner_output, executor_step, etc.) are either: +- Not serialized with `loop_id` at all +- Emitted as A2A `TaskArtifactUpdate` instead of SSE loop events +- Lost in the LangGraph `astream_events` → A2A conversion + +**Fix**: Ensure `event_serializer.py` emits ALL node events with `loop_id` in the SSE stream. The `loop_id` must be consistent across all events in a single graph execution. + +**Impact**: Without this fix, session reload shows empty loops because the DB has only 1 event (router). The SSE stream itself works (UI renders correctly during streaming) but the data is lost for persistence. + +### 3. Per-Session UID Isolation +Currently all sessions share UID 1001 on the PVC. Need per-session UID mapping (from passover W item #5). + +### 4. tdd:ui-hypershift Skill Needs Genericization +Contains hardcoded worktree paths (`sandbox-agent`). Should use variables. + +### 5. Wizard Reconfigure Not Tested on Cluster +The reconfigure feature compiles and has all endpoints but wasn't deployed/tested on sbox42 yet. + +### 6. Agent Ends After Few Steps +The agent sometimes ends after 1-2 steps despite having more plan steps. May be related to how the executor handles the transition from tool results back to reasoning. Need to verify the graph topology fix resolved this. + +### 7. Budget Controls in Wizard + Session Detail +Add a "Budget" step to the wizard showing all configurable limits with defaults: +- `SANDBOX_MAX_ITERATIONS` (100), `SANDBOX_MAX_TOKENS` (1M) +- `SANDBOX_LLM_TIMEOUT` (300s), `SANDBOX_LLM_MAX_RETRIES` (3) +- `SANDBOX_MAX_TOOL_CALLS_PER_STEP` (10), `SANDBOX_HITL_INTERVAL` (50) +These are passed as env vars to the agent pod. The test can skip this step (defaults are fine). +Also show live budget consumption in the session Stats tab. + +### 8. Agent Redeploy E2E Test +New Playwright test that: +1. Deploys agent via wizard with specific security/config settings +2. Changes settings via reconfigure modal (e.g., toggle proxy, change model) +3. Asserts agent reaches Ready state on the agents page +4. Continues a session — verifies the agent remembers previous context +5. Tests workspace persistence (file created in session history is still readable after redeploy) + +### 9. Message Queue + Cancel Button +When the agent loop is running, any new messages sent should be **queued** (not sent immediately). The UI should show: +- A **cancel button** on the agent loop card (top right) to abort the running loop +- Queued messages shown as pending below the active loop +- After cancel or completion, queued messages are sent in order +- This prevents the double-send issue and gives users control over long-running loops + +### 10. LLM Usage Panel Broken +`[rca] LLM Usage panel visible: false` — the LlmUsagePanel reads from OTEL/Phoenix traces. Likely the OTEL collector or Phoenix isn't receiving traces after redeployments. Check OTEL endpoint config and Phoenix connectivity. + +### 11. Subsessions Panel Shows Nothing +The SubSessionsPanel only shows data when the agent uses the `delegate` tool to spawn child sessions. For RCA tasks without delegation, this is expected. Consider showing "No sub-sessions" message instead of empty panel. + +### 12. Kiali Graph Missing LiteLLM + Squid Proxy +LiteLLM proxy and Squid egress proxy don't appear in the Kiali graph. Both need to be enrolled in Istio ambient mesh: +- Add `istio.io/dataplane-mode: ambient` label to LiteLLM and Squid Deployment pod templates +- Or label their namespaces for ambient enrollment +- This enables Kiali to show traffic flows: agent → squid → internet, agent → litellm → vLLM + +### 13.

The agent's LLM calls take 30+ seconds (Llama 4 Scout via LiteLLM), and during that time only keepalive pings are sent. The planner/executor/reflector events are produced after the LLM responds but by then the backend's SSE stream may have ended (client navigated, nginx timeout, or test progression). + +**The `_recover_loop_events_from_agent` fallback function exists** (sandbox.py line 1984) but the logs show it's NOT running. Check: +1. Is `session_has_loops` True? (Should be — router event has loop_id) +2. Is `has_reporter` False? (Should be — no reporter event in 1 loop_event) +3. Is `loop_events_persisted` False?

Then extract loop_events from the task history.

Moved ALL persistence to background task `_persist_and_recover()` — immune to GeneratorExit. | +| **Recovery polling** | `_recover_loop_events_from_agent` now polls with exponential backoff (5s→60s, 10 retries) waiting for task COMPLETED/FAILED state. | +| **micro_reasoning events** | New event type emitted between executor tool calls. Each executor micro-step captures reasoning, prompt, tokens. | +| **PromptInspector overlay** | Fullscreen overlay (ESC/X to close) showing system prompt, input messages, LLM response, tokens for any node. | +| **Full prompt data** | Increased truncation: system_prompt 3K→10K, messages 500→5000 chars, 30→100 entries. Model name now populated. | +| **Token display** | micro-reasoning blocks show token usage and model name inline. | + +### NEW P0: Token Budget Not Enforced + +**CRITICAL**: `budget.add_tokens()` is NEVER called — token tracking is dead code. +- `AgentBudget.max_tokens = 1_000_000` exists but `tokens_used` is never incremented +- `tokens_exceeded` is never checked by any node +- Only `max_iterations` is enforced (in reflector only) +- Session `10f9e8471d034583a09f900c9c589617` consumed 1.49M tokens without stopping + +**Fix needed in `reasoning.py`:** +1. After each LLM call, call `budget.add_tokens(prompt_tokens + completion_tokens)` +2. In reflector AND executor, check `budget.tokens_exceeded` and force done +3. Emit a `budget_update` event after each node with current usage + +### NEW P0: Context Window Management + +**Problem**: LangGraph message history grows unbounded. Each LLM call includes ALL previous messages. When history exceeds the model's context window (131K for Llama 4 Scout), calls either fail or get truncated silently. + +**UI shows wrong number**: Stats tab shows "1,489,577 / 131,072 tokens (1136.5%)" — this compares CUMULATIVE tokens (all calls summed) to the PER-CALL context window. These are different metrics: +- **Cumulative usage**: total tokens consumed across all LLM calls (budget tracking) +- **Context window usage**: tokens in the CURRENT call vs model's max context + +**Needs:** +1. **Message trimming in graph**: Before each LLM call, trim history to fit within context window (e.g., keep system prompt + last N messages within 100K). Use LangGraph's `trim_messages` or custom trimmer. +2. **Per-call context tracking**: Emit `prompt_tokens` per node (already done), show it as "context: X/131K" in the UI. +3. **UI fix**: Don't show cumulative tokens as context window %. Show two separate metrics: + - "Total usage: 1.49M tokens" (cumulative, budget) + - "Last call: 45K/131K context" (per-call, window) + +### Remaining P0 items (from Session X) + +| # | Item | Notes | +|---|------|-------| +| 1 | ~~loop_events persistence~~ | FIXED — background task | +| 2 | **Budget controls in wizard + reconfigure** | Wizard step showing SANDBOX_MAX_ITERATIONS, SANDBOX_MAX_TOKENS, SANDBOX_MAX_TOOL_CALLS_PER_STEP as editable fields with defaults.

Budget values passed as env vars on deploy. | +| 3 | **RCA quality 3/5** | Reporter prompt formatting for Llama 4 Scout | +| 4 | ~~Agent ends after few steps~~ | Partially fixed — recovery polling fills gaps | +| 5 | **Message queue + cancel button** | Queue messages during loop, cancel button top right | +| 6 | **Visualizations tab** | Design doc at `2026-03-10-visualizations-design.md` | +| 7 | **Kiali ambient mesh** | LiteLLM + Squid need `istio.io/dataplane-mode: ambient` | +| 8 | **Agent redeploy E2E test** | Test reconfigure, session continuation, workspace persistence | +| 9 | **Per-session UID isolation** | fsGroup is stopgap, need per-session UIDs | +| 10 | **LLM usage panel** | OTEL/Phoenix trace export broken | +| 11 | **Subsessions panel** | Show "No sub-sessions" instead of empty | +| 12 | **Reflector prompt says "continue"** | Should say "execute" to match route name | +| 13 | **Loop failure reason not shown** | Failed agent loops should show the error reason next to the failure icon | +| 14 | **Agent writes outside workspace** | `mkdir ../../output` fails — skills/prompts reference paths outside `/workspace` | +| 15 | **Token budget enforcement** | NEW — `add_tokens()` never called, budget is dead code | +| 16 | **Context window management** | NEW — no message trimming, UI shows wrong metric | +| 17 | **DB metadata race condition** | CRITICAL: A2A SDK's `DatabaseTaskStore.save()` overwrites metadata column via `session.merge()`. Backend writes `{owner, agent_name, loop_events}`, A2A SDK replaces with `{}`. **Quick fix**: `ALTER TABLE tasks ADD COLUMN backend_meta jsonb DEFAULT '{}'::jsonb` — SDK won't touch it. Then change all backend reads/writes from `metadata` to `backend_meta`. **Design needed**: long-term storage architecture for sessions, metadata, loop_events, checkpoints. | +| 18 | **SSE stream closes at 30s — use tasks/resubscribe** | Agent's A2A SSE handler closes mid-stream. FIX: use A2A `tasks/resubscribe` method to reconnect to the running task's event stream instead of polling `tasks/get`. The SDK's `on_resubscribe_to_task()` taps into the existing EventQueue and returns a new SSE stream. Backend should: detect stream closure without [DONE], call `tasks/resubscribe` with the A2A task ID, continue forwarding events. This gives real-time events instead of post-hoc recovery polling. | +| 19 | **Double-send UI bug** | 3rd session created during tests.

Agent Reasoning Architecture + +Sandbox agents use a **plan-execute-reflect** loop implemented in LangGraph. +Each iteration plans work, executes tool calls, then reflects on progress. + +```mermaid +flowchart TD + Start([User message]) --> Planner + + subgraph Loop["Reasoning Loop (budget-bounded)"] + Planner["Planner LLM

Synthesizes final answer"] --> End([Response to user]) + + BudgetCheck["Budget check
(tokens, steps)"] -.->|"enforced at each node"| Loop +``` + +**Key design decisions:** + +- **Micro-reasoning:** After each tool call, the executor runs a lightweight LLM + call to interpret the result before deciding the next tool. This catches errors + early and reduces wasted tool calls. +- **Reflector decides termination:** No hardcoded stall detection. The reflector + LLM evaluates remaining plan steps and decides continue/replan/done. +- **Budget enforcement:** Token and step budgets are checked at every node + transition. Currently in-memory; moving to LLM proxy (see + [Section 7](#7-llm-budget-enforcement)). +- **Reporter always runs LLM:** Even for single-step results, the reporter + synthesizes through its own LLM call to avoid leaking reflector reasoning. + +See [Reasoning Loop Design](./2026-03-03-sandbox-reasoning-loop-design.md) for +full LangGraph graph structure, state schema, and prompt templates. + +--- + +## 5. Human-in-the-Loop Flow + +HITL gates allow users to approve or deny dangerous operations (shell commands, +file writes, network calls) before the agent executes them. + +```mermaid +sequenceDiagram + participant User + participant UI as Kagenti UI + participant Backend as FastAPI Backend + participant Agent as Sandbox Agent + participant Tool as Tool (shell, file, etc.) + + User->>UI: Send message + UI->>Backend: POST /chat (SSE) + Backend->>Agent: A2A send_message + Agent->>Agent: Plan + begin execution + + Note over Agent: Tool requires approval + Agent->>Backend: HITL event (tool_name, args, risk_level) + Backend->>UI: SSE hitl_request event + UI->>UI: Render Approve/Deny buttons + + alt Approved + User->>UI: Click Approve + UI->>Backend: POST /hitl/approve + Backend->>Agent: Resume with approval + Agent->>Tool: Execute tool + Tool-->>Agent: Result + Agent->>Backend: Tool result event + Backend->>UI: SSE tool_result event + else Denied + User->>UI: Click Deny + UI->>Backend: POST /hitl/deny + Backend->>Agent: Resume with denial + Agent->>Agent: Reflector handles denial, may replan + end + + Agent->>Backend: Final answer + Backend->>UI: SSE message event + UI->>UI: Render response +``` + +**Current status:** +- Approve/Deny buttons render in chat via `ToolCallStep` component +- Backend HITL endpoints exist and forward to agent +- Resume after approval is partially wired (works for shell commands) +- Sidecar agents can trigger HITL requests (planned) + +--- + +## 6. Database Architecture + +Each agent namespace has its own PostgreSQL StatefulSet. Database isolation uses +a **schema-per-agent** model to separate checkpoint data while sharing session +metadata within a team. + +```mermaid +erDiagram + TEAM_SCHEMA { + uuid id PK "task/session ID" + jsonb metadata "owner, visibility, agent_name" + text status "submitted, working, completed, failed" + timestamp created_at + timestamp updated_at + } + + TEAM_SCHEMA ||--o{ LLM_CALLS : "tracks token usage" + LLM_CALLS { + uuid id PK + uuid session_id FK + text model + int input_tokens + int output_tokens + float cost + text node_name "planner, executor, reflector, reporter" + timestamp created_at + } + + AGENT_SCHEMA { + text thread_id PK "LangGraph thread" + text checkpoint_ns + bytea checkpoint "serialized LangGraph state" + jsonb metadata + } + + AGENT_SCHEMA ||--o{ CHECKPOINT_WRITES : "incremental updates" + CHECKPOINT_WRITES { + text thread_id FK + text checkpoint_ns + text checkpoint_id + text task_id + int idx + bytea channel + bytea value + } +``` + +**Design decisions:** +- **Team schema** (`team1`): Holds `a2a_tasks` (session records) and `llm_calls` + (token tracking). Shared across all agents in the namespace. +- **Agent schema** (`sandbox_legion`, `sandbox_hardened`, ...): Holds LangGraph + checkpoint tables. One schema per agent deployment. The wizard creates/drops + schemas on agent deploy/undeploy. +- **Connection management:** Each agent gets a dedicated DB user with access only + to its own schema plus read access to the team schema. + +See [DB Multi-Tenancy Design](./2026-03-12-db-multi-tenancy-design.md) for +schema creation SQL, connection string templating, and wizard integration. + +--- + +## 7. LLM Budget Enforcement + +Budget enforcement prevents runaway token consumption. The current in-memory +approach is being replaced by a dedicated LLM budget proxy. + +```mermaid +flowchart LR + Agent["Sandbox Agent"] -->|"LLM request"| Proxy["LLM Budget Proxy

The agent emits a `budget_update` event, and the UI displays budget +status in the `LoopSummaryBar`. + +See [LLM Budget Proxy Design](./2026-03-12-llm-budget-proxy-design.md) for +proxy architecture, API contract, and phased implementation plan. See also +[Budget Limits Design](./2026-03-12-budget-limits-design.md) for naming +conventions (recursion vs cycles vs steps). + +--- + +## 8. Sidecar Agents + +Sidecar agents run alongside the primary sandbox agent and observe or augment +its behavior without modifying the agent code. + +| Sidecar | Purpose | Status | +|---------|---------|--------| +| **Looper** | Auto-continue: detects when agent paused mid-task and sends follow-up messages | Partial (exists, 0 observations -- debugging) | +| **Hallucination Observer** | Monitors tool call results for signs of hallucinated paths, APIs, or commands | Not built | +| **Context Guardian** | Tracks context window usage, triggers passover when approaching limits | Not built | + +Sidecar agents are managed by the backend's `SidecarManager`. They subscribe to +the same SSE event stream as the UI and can trigger HITL requests or inject +messages into the session. + +--- + +## 9. Event Pipeline + +The event pipeline streams reasoning loop events from agent to UI in real-time +and persists them for historical reconstruction. + +**Five-stage pipeline:** + +1. **LangGraph events** -- Agent emits typed events (plan, tool_call, reflection, + budget_update, hitl_request) during graph execution +2. **SSE forwarding** -- Backend receives A2A streaming events and forwards via + Server-Sent Events to the UI +3. **Loop event persistence** -- Background task writes events to `loop_events` + table (immune to GeneratorExit) +4. **Historical reconstruction** -- On session reload, backend queries persisted + events and replays them in the same format as live SSE +5. **Recovery polling** -- UI polls for missed events on reconnect, merging with + live stream + +See [Loop Event Pipeline Design](./2026-03-09-loop-event-pipeline-design.md) for +event schema, streaming vs history parity, and recovery protocol. + +--- + +## 10. Multi-Framework Agent Runtime + +The platform is **framework-neutral**. It owns infrastructure (A2A server, auth, +security, workspace, observability) while agents provide only business logic. +The A2A protocol is the composability boundary — any agent that speaks A2A +JSON-RPC 2.0 gets the full platform feature set for free. + +``` ++---------------------------------------------------------------+ +| Platform Layer (Kagenti-owned, transparent to agents) | +| | +| A2A Server AuthBridge Composable Security (L1-L8) | +| Workspace Skills Loader OTEL Instrumentation | +| Session DB LLM Budget Egress Proxy | ++---------------------------------------------------------------+ +| A2A JSON-RPC 2.0 + agent card + SSE events | ++---------------------------------------------------------------+ +| Agent Layer (pluggable, user-provided) | +| | +| LangGraph OpenCode Claude Agent SDK | +| OpenHands OpenClaw Custom HTTP service | ++---------------------------------------------------------------+ +``` + +Non-native agents use a thin **A2A wrapper** (~200 lines) that translates +between the agent's protocol and A2A JSON-RPC: + +| Framework | Language | Integration | Wrapper | +|-----------|----------|-------------|---------| +| **LangGraph** | Python | Native A2A, runs as graph inside platform base image | None needed | +| **OpenCode** | Go | `opencode serve` exposes HTTP API, wrapper translates events | `opencode_wrapper.py` | +| **Claude Agent SDK** | Python | `query()` calls wrapped in A2A executor | `claude_sdk_wrapper.py` | +| **OpenHands** | Python | Docker-based controller, wrapper proxies events | `openhands_wrapper.py` | +| **OpenClaw** | Python | HTTP API, wrapper translates events | `openclaw_wrapper.py` | +| **Custom** | Any | Any HTTP service exposing a streaming endpoint | Custom wrapper | + +**Key principle:** Adding AuthBridge, Squid proxy, Landlock, or any platform +feature requires **zero changes** to agent code.

Polling doesn't update loop events (ROOT CAUSE of stale UI) + +**Impact:** After streaming ends, the 5-second polling fetches history but only updates `messages`, ignoring `loop_events`. Reflector nodes, step progression, and final answers never appear after initial load. + +**Fix:** In the polling `useEffect` (SandboxPage.tsx ~line 1183), also check `histPage.loop_events` and merge new events into `agentLoops` using `applyLoopEvent`. Don't rebuild from scratch — only apply events not already in the loop. + +**File:** `kagenti/ui-v2/src/pages/SandboxPage.tsx` (polling useEffect) + +### 2. Active streaming session pulls user back when navigating away + +**Impact:** If you're viewing a streaming session and navigate to another page/session, the subscribe stream's state updates pull you back. + +**Fix:** The subscribe AbortController should also abort when the user navigates away from the sandbox page entirely (not just session switch). Add cleanup in the component unmount / route change. + +**File:** `kagenti/ui-v2/src/pages/SandboxPage.tsx` (_subscribeToSession, useEffect cleanup) + +### 3. Executor still runs multiple plan steps in one burst + +**Impact:** With `tool_choice="any"`, the executor MUST call a tool every response. It can never produce text-only to signal "step done". So it keeps calling tools across plan steps without returning to the reflector. The `max_tool_calls_per_step=20` is the only boundary. + +**Options:** +a. Lower `max_tool_calls_per_step` to 5 (simple but blunt) +b. Add a programmatic check in executor: after each tool result, check if the current plan step's description was achieved (heuristic) +c. The step_selector already sets `current_step` — the executor should check if its assigned step matches what it's actually doing + +**File:** `reasoning.py` executor_node, `graph.py` step_selector + +### 4. Step numbering gaps in UI + +**Impact:** Node visit counter shows [3], [4], [7], [9] — gaps where router/planner/reflector visits consume numbers but aren't shown as executor steps. The user expects sequential [1], [2], [3]. + +**Fix:** Use a separate counter for executor-only steps, or renumber steps in the UI based on render order rather than the raw node visit index. + +**File:** `loopBuilder.ts` (track executor step count separately) + +### 5. PVC test still fails (extra Next click might not be enough) + +**Impact:** The wizard deploy test times out or fails. May need more robust wizard navigation (click step labels instead of Next buttons). + +**File:** `e2e/agent-rca-workflow.spec.ts` + +## P1: Should Fix + +### 6. Page load jankiness (partially fixed) + +Loading overlay added but polling still causes re-renders. The polling should be gated until initial load completes. + +### 7. Backend OOM on large histories + +SQL-based extraction added but untested under load. The write-back mechanism should prevent repeated extraction. Monitor backend restarts. + +### 8. Planner prompt block not showing in UI + +Debug logging added but root cause not found. The data reaches the loopBuilder (`system_prompt` and `prompt_messages` present in events) but PromptBlock may not render for planner steps. Check browser console for `[PromptBlock]` logs. + +### 9. Context window management + +Executor windowing at 30K tokens helps but is approximate (chars/4). For Llama 4 Scout (131K context), a more precise tokenizer would be better. Also, the planner and reporter still send full history. + +### 10. Step 2a/2b retry naming + +When a plan step fails and is replanned, the new attempt should be labeled `Step 2a`, `Step 2b`, etc. Currently all retries show as `Step 2`. + +**File:** `loopBuilder.ts` (track replan count per plan step) + +### 11. Micro-reasoning context bloat + +Micro-reasoning (executor between tool calls) still sends growing context. After a `gh api` returns 10KB (truncated), every subsequent micro-reasoning includes it. The windowing helps but doesn't specifically target micro-reasoning. + +### 12. Agent uses `cd` as separate command + +The agent keeps trying `shell("cd repos/kagenti")` as a standalone command (which doesn't persist). Despite the prompt saying "chain commands with &&", Llama 4 Scout doesn't always follow. Consider: +- Intercepting `cd` commands and converting to `cwd` parameter +- Prepending `cd X &&` to subsequent commands automatically + +## P2: Nice to Have + +### 13. Budget display real-time (budget_update events) + +Budget section shows data from loop state but the agent's `budget_update` events aren't flowing to the UI (event_serializer emits them but the UI doesn't process the `budget` event type from SSE).

Other nodes (planner, reflector, reporter) can use the global counter for ordering but should NOT label their steps as "Step 29". + +The UI's `StepSection` header should show: +- Planner: "Plan (iteration N)" +- Executor: "Step N: {plan_step_description}" +- Reflector: "Reflection [continue/replan/done]" +- Reporter: "Final answer" + +NOT "Step 29: ..." for everything. + +### Files +- Agent: `event_serializer.py` — use `current_step` for executor events +- UI: `LoopDetail.tsx` StepSection — render step label based on nodeType + +## P0: Reflector Gets No Conversation Context + +### Problem +The reflector's prompt shows `system_prompt` (5000 chars) but `prompt_messages: 0`.

Step Re-selection Loop + +Steps keep going back to step 1 because the reflector/planner cycle resets +`current_step`.

Executor "Step completed" Without LLM Call + +When `_no_tool_count >= 2` (two consecutive responses with no tool calls), +the executor produces "Step completed" as text with 0 tokens. This fires +even when the step wasn't actually completed — the executor just couldn't +figure out what tool to call. + +### 5. "Step completed" Text from Dedup Path + +When the executor's tool calls are deduplicated (already executed), it +produces "Step completed" without running the LLM. The UI shows this as +a micro-reasoning event with 0 tokens.
