From 7ef42d88a5fb90d583f4161b287b710d9a6c27a5 Mon Sep 17 00:00:00 2001 From: Coding Agent Date: Sun, 1 Mar 2026 09:45:32 +0000 Subject: [PATCH 1/5] feat: Add model and thread_id metadata to commits and PRs This change introduces metadata to git commits and pull request descriptions to improve traceability of the agent's actions. - The `AgentState` now includes a `thread_id`. - The `GitRepo.commit_all` and `GitRepo.create_pull_request` methods now accept `model` and `thread_id` parameters and append them to the commit message and PR body respectively. - The `AgentLoop` now generates a `thread_id` and adds it to the initial agent state. - Tests have been added to verify that the metadata is correctly formatted in commits and PRs. --- src/agent/loop.py | 20 +++++++------- src/agent/state.py | 3 ++- src/git_ops/repo.py | 30 +++++++++++++++++---- tests/test_git_repo.py | 61 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 99 insertions(+), 15 deletions(-) diff --git a/src/agent/loop.py b/src/agent/loop.py index d1dcf78..05f3071 100644 --- a/src/agent/loop.py +++ b/src/agent/loop.py @@ -54,14 +54,6 @@ async def run(self) -> str: logger.info("State store ready") graph = build_graph(checkpointer=checkpointer) - initial_state = { - "task": self.task, - "settings": self.settings, - "repo_config": self.repo_config, - } - if self.branch: - initial_state["branch"] = self.branch - # Deterministic thread_id for checkpoint resumability. # When a branch is given we use it directly; otherwise we derive # a stable id from repo+task so re-runs of the same task resume. @@ -70,6 +62,16 @@ async def run(self) -> str: else: key = f"{self.repo_config.name}/{self.task}" thread_id = hashlib.sha256(key.encode()).hexdigest()[:16] + + initial_state = { + "task": self.task, + "settings": self.settings, + "repo_config": self.repo_config, + "thread_id": thread_id, + } + if self.branch: + initial_state["branch"] = self.branch + config: dict = {"configurable": {"thread_id": thread_id}} if self.settings.tracing.enabled: config["tags"] = [ @@ -98,4 +100,4 @@ async def run(self) -> str: input_tokens, output_tokens, cost, ) - return final_state.get("result", "No result") + return final_state.get("result", "No result") \ No newline at end of file diff --git a/src/agent/state.py b/src/agent/state.py index a497f49..fb40ea9 100644 --- a/src/agent/state.py +++ b/src/agent/state.py @@ -22,6 +22,7 @@ class AgentState(TypedDict, total=False): settings: Annotated[Settings, UntrackedValue] repo_config: Annotated[RepoConfig, UntrackedValue] branch: Annotated[str | None, UntrackedValue] + thread_id: Annotated[str, UntrackedValue] # Initialised in clone_and_branch, reused across nodes — not checkpointed readme_preamble: Annotated[str, UntrackedValue] @@ -56,4 +57,4 @@ class AgentState(TypedDict, total=False): token_usage: dict[str, int] # Final output - result: str + result: str \ No newline at end of file diff --git a/src/git_ops/repo.py b/src/git_ops/repo.py index e04cffc..78211f2 100644 --- a/src/git_ops/repo.py +++ b/src/git_ops/repo.py @@ -267,14 +267,20 @@ def checkout_or_create_branch(self, branch_name: str) -> str: return branch_name - def commit_all(self, message: str) -> bool: + def commit_all(self, message: str, model: str, thread_id: str) -> bool: """Stage all changes and commit.
