The tool uses repo-relative paths but the graph +stores IDs as `::`. When the MCP server serves a combined +`synapses-os` root index, the file-path strip logic doesn't handle the project +subdirectory prefix correctly. +**Fix:** Normalise incoming file paths against the graph's repo prefix before +matching. Try `::` → strip `/` from incoming path. + +#### BUG-S02 — get_impact returns `tiers: null` instead of empty array +**Severity:** Low +**Observed:** Querying `get_impact` on `Server.handleGetContext` (a tool handler +registered by function pointer, not called by Go code) returns `tiers: null`. +Callers should get `tiers: []` for a clearly empty result, not null, which +breaks JSON consumers that do `tiers.length`. +**Fix:** Initialise `tiers` to `[]` (empty slice) before returning, never nil. + +#### BUG-S03 — MCP server does not pick up synapses.json changes without restart +**Severity:** Medium +**Observed:** After adding `brain.url` + `scout.url` to `synapses.json`, the +running MCP server (managed by Claude Code) continued with no brain/scout +client. Config is read once at startup. +**Fix:** Add a SIGHUP handler or `config.Watch()` loop that re-reads +`synapses.json` every 60s and calls `server.SetBrainClient()` / +`server.SetScoutClient()` if the URL has changed. Alternatively add a +`session_reload_config` MCP tool. + +#### BUG-S04 — Brain/scout not configured by default — silent failure in get_context +**Severity:** Medium +**Observed:** A freshly-installed `synapses` binary has no `synapses.json`. +`get_context` returns graph-only results with zero indication that brain +enrichment is missing. No `brain_unavailable: true` field or warning. +**Fix:** In `handleGetContext`, if `getBrainClient()` returns nil, add a +`"brain": "not configured — add brain.url to synapses.json"` hint to the +response JSON. Same for scout tools returning "scout unavailable". + +--- + +### USABILITY ISSUES + +#### UX-S01 — get_impact requires exact method syntax (`Server.X`), find_entity accepts substrings +**Observed:** `get_impact("handleGetContext")` → "entity not found". +`find_entity("handleGetContext")` → finds it. Two tools, two lookup behaviours. +**Improvement:** `get_impact` should fall back to `Graph.FindByName` (same +fuzzy lookup as `find_entity`) when the exact ID isn't found. Return a "did you +mean: Server.handleGetContext?" hint if zero results. + +#### UX-S02 — create_plan auto-links nodes with poor relevance +**Observed:** Creating a plan titled "Test synapses core MCP tools" auto-linked +`synapses-scout/src/scout/server.py::search` — completely irrelevant. The +auto-linker used BM25 on task title/description and picked the wrong project. +**Improvement:** Auto-linking should be scoped to the repo the MCP server is +serving. Cross-project node links should require explicit `linked_nodes` from +the caller. Add a `confidence` threshold (e.g. ≥0.7) below which auto-links +are dropped. + +#### UX-S03 — `search(mode="semantic")` is misleading — it's BM25, not vector +**Observed:** `search("rate limiting throttle concurrency")` returns 0 results +with hint "try broader terms". No semantic/embedding expansion occurs. The mode +name suggests vector similarity but the implementation is FTS BM25. +**Improvement:** Either: + a. Rename to `mode="fts"` and `mode="keyword"`. + b. Or implement actual embedding-based search using a local model + (sentence-transformers/nomic-embed) for true semantic retrieval. + c. At minimum, document clearly what "semantic" means in the tool description. + +#### UX-S04 — get_file_context("server.go") returns mixed entities from all files with that name +**Observed:** The combined `synapses-os` root index has three `server.go` files +(synapses/mcp, synapses-intelligence/server, synapses-scout/server.py). All +entities are returned mixed together with no file-path grouping or attribution. +**Improvement:** Show the file path for each entity in `get_file_context` +output, and group results by file when multiple files match the suffix. Allow +full-path overrides (e.g. `get_file_context("internal/mcp/server.go")`). + +#### UX-S05 — get_working_state ignores config/JSON file changes +**Observed:** After creating `synapses.json` and editing `settings.json`, both +returned zero recent changes. The watcher watches source files only (.go, .py, +.ts etc.) and ignores config files. +**Improvement:** Include `*.json`, `*.yaml`, `*.toml`, `Makefile`, +`Dockerfile` changes in `get_working_state`. These are often the most +significant indicator of configuration changes relevant to the agent. + +--- + +### ARCHITECTURE GAPS + +#### ARCH-S01 — No federation: cross-project graph edges don't exist +**Observed:** The `synapses-core` MCP server (serving `synapses/`) has no graph +edges into `synapses-intelligence/` or `synapses-scout/`. The call from +`brain/client.go` to `localhost:11435` is an HTTP boundary the static analyser +cannot cross. +**Future:** Add a `federation` mode where HTTP calls matching known sidecar URLs +(brain, scout) generate synthetic `CALLS_REMOTE` edges. This would let +`get_call_chain("cmdStart", "Enricher.Enrich")` work end-to-end across +projects. Tracked under `is_federated: false` in `get_project_identity`. + +#### ARCH-S02 — `session_init` tool exists but is not in CLAUDE.md startup ritual +**Observed:** `handleSessionInit` consolidates `get_pending_tasks` + +`get_project_identity` + `get_working_state` into one call. But CLAUDE.md +still lists the three-step ritual. Agents are paying 3× round-trips at startup. +**Fix:** Update CLAUDE.md to: `session_init() ← FIRST: single-call bootstrap`. +Remove the three-step ritual. Reduces session start from ~3 MCP calls to 1. + +#### ARCH-S03 — No MCP tool for reading a stored brain summary by name (only by node_id) +**Observed:** `GET /v1/summary/{nodeId}` requires the exact stored `node_id` +(e.g. `synapses::cmdStart`). There is no `GET /v1/summary?name=cmdStart` fuzzy +lookup. Agents that don't know the node_id cannot retrieve summaries from the +graph context. +**Improvement:** Add a `search_summary` MCP tool or query param that accepts a +name/fuzzy string, looks up matching node IDs in brain.sqlite, and returns +summaries for all matches. + +#### ARCH-S04 — No config hot-reload; synapses.json changes require MCP server restart +See BUG-S03. In a production setup, the MCP server is a long-lived process +managed by Claude Code. There is currently no way to reconfigure brain/scout +URLs without restarting the entire Claude Code session. + +--- + +### PERFORMANCE NOTES + +- **Index time:** `synapses index` on 90 files took ~2s — acceptable. +- **get_context latency:** <50ms on warm cache — excellent. +- **get_project_identity:** ~20ms — excellent. +- **search(keyword):** ~5ms — excellent. +- **search(semantic):** ~10ms — excellent (BM25, not vector). +- **Concern:** Adding vector embeddings (ARCH gap above) would add ~100-500ms + per query unless pre-computed and stored in SQLite. diff --git a/internal/brain/client.go b/internal/brain/client.go index 4996f9c..33a1954 100644 --- a/internal/brain/client.go +++ b/internal/brain/client.go @@ -172,6 +172,68 @@ func (c *Client) SetPhase(ctx context.Context, req SetPhaseRequest) (*SDLCConfig return &out, nil } +// UpsertADR calls POST /v1/adr to create or update an ADR. +func (c *Client) UpsertADR(ctx context.Context, req ADRRequest) (*ADR, error) { + var out ADR + if err := c.post(ctx, "/v1/adr", req, &out); err != nil { + return nil, err + } + return &out, nil +} + +// GetADR calls GET /v1/adr/{id} to retrieve an ADR by ID. +func (c *Client) GetADR(ctx context.Context, id string) (*ADR, error) { + httpReq, err := http.NewRequestWithContext(ctx, http.MethodGet, c.baseURL+"/v1/adr/"+url.PathEscape(id), nil) + if err != nil { + return nil, err + } + resp, err := c.cli.Do(httpReq) + if err != nil { + return nil, err + } + defer resp.Body.Close() + if resp.StatusCode == http.StatusNotFound { + return nil, fmt.Errorf("ADR %q not found", id) + } + if resp.StatusCode < 200 || resp.StatusCode >= 300 { + body, _ := io.ReadAll(io.LimitReader(resp.Body, 512)) + return nil, fmt.Errorf("HTTP %d: %s", resp.StatusCode, string(body)) + } + var out ADR + if err := json.NewDecoder(resp.Body).Decode(&out); err != nil { + return nil, err + } + return &out, nil +} + +// GetADRs calls GET /v1/adr (optionally with ?file=path) to retrieve ADRs. +func (c *Client) GetADRs(ctx context.Context, fileFilter string) ([]ADR, error) { + u := c.baseURL + "/v1/adr" + if fileFilter != "" { + u += "?file=" + url.QueryEscape(fileFilter) + } + httpReq, err := http.NewRequestWithContext(ctx, http.MethodGet, u, nil) + if err != nil { + return nil, err + } + resp, err := c.cli.Do(httpReq) + if err != nil { + return nil, err + } + defer resp.Body.Close() + if resp.StatusCode < 200 || resp.StatusCode >= 300 { + body, _ := io.ReadAll(io.LimitReader(resp.Body, 512)) + return nil, fmt.Errorf("HTTP %d: %s", resp.StatusCode, string(body)) + } + var out struct { + ADRs []ADR `json:"adrs"` + } + if err := json.NewDecoder(resp.Body).Decode(&out); err != nil { + return nil, err + } + return out.ADRs, nil +} + // post marshals body as JSON, POSTs to the endpoint, and decodes the response // into out (if out is non-nil).
