Near the budget or at the last allowed call, it removes the tools so the model must return structured findings; jumping to `end` would return none. + - `TraceMiddleware` records the real tool calls as a `ReactTrace`. +- **Reflection** (`app/agents/reflection.py`): + - Returns keep/drop/merge *decisions*; `apply_decisions()` applies them in code, so attribution survives. + - Line numbers are cleared unless they fall on commentable diff lines. + - The same node, given the judge's feedback, is `revise`. +- **Judge:** `app/eval/judge.py`, native `json_schema` structured output. +- **`human_gate`:** computes `gate_reasons`. Its behaviour depends on the graph mode: + - `report` (default: tests, MCP, eval) and `action`: never pause. + - `local`: `interrupt()`, which needs a checkpointer. +- **`publish`:** calls `deps.publisher` if one is set. +- **State reducers:** the parallel reviewers write `draft_findings` and `traces` (`operator.add`) and `budget_limited` (`operator.or_`). `ReviewService._merge_delta` mirrors these using `ADDITIVE_KEYS`/`OR_KEYS` from `state.py`. Only the three reviewers may append to `traces`; tests assert this, and reflection's trace goes in `reflection_trace`. +- **Dependencies:** `make_deps(client, workspace, settings, cfg=, publisher=)` builds `EngineDeps` (`app/agents/deps.py`). `ReviewConfig` (`app/review_config.py`) merges a repo's `.codesage.yml` over env settings; `prepare_diff()` applies the ignore globs and `max_files`. +- **Where graphs are built:** `app/action/__main__.py`, `ReviewService`, `app/mcp/server.py` and `app/eval/harness.py`. + +**Workspace and diff** (`app/workspace/`, `app/diff/`): +- **Tools:** `read_file`, `search_code` (`git grep`), `list_dir`, `git_log`, `git_blame`, `get_diff`, `run_tests` and `semantic_search`. They are LangChain tools, and errors come back as `"error: …"` strings, not exceptions. + - Paths are resolved, symlinks included, and must stay inside the root. + - `.git` is refused, case-insensitively. + - Output is capped at 12,000 chars. +- **`run_tests`:** runs only when `.codesage.yml` sets `tests.command`, and is offered only to the correctness reviewer. It gets a scrubbed environment (no tokens or keys) and a process-group timeout (`app/workspace/proc.py`). +- **Three workspace shapes:** + - `Workspace(root, diff)`: the Action's checkout. + - `Workspace.clone_at(...)`: local PR mode, a blobless temporary clone; the token is passed via `GIT_CONFIG_*` env, never written to `.git/config`. + - `Workspace.diff_only(...)`: local diff mode. +- **`Diff.is_commentable(path, line)`:** true for added or context lines on the RIGHT side. These are the only lines GitHub accepts for inline comments. + +**GitHub Action** (`action.yml`, `app/action/`, `app/publish/`): +- **Steps:** setup-python@v7 → `pip install` the engine into a venv → `codesage-action resolve` → checkout@v7 at the head SHA (full history, `persist-credentials: false`) → `codesage-action review`. + - It is a console script, **not** `python -m app.action`: `-m` would put the reviewed repo first on `sys.path`, so a repo with its own `app/` package would be imported. +- **Triggers** (`app/action/rules.py`, mirrored in `examples/codesage-workflow.yml`): + - PR opened (not a draft) or marked ready for review + - the `codesage:review` label, which is removed afterwards + - a `/codesage review` comment from OWNER/MEMBER/COLLABORATOR + + Forks are skipped. +- **Publishing:** `GitHubPublisher` posts one `COMMENT` review with up to 30 inline comments (retrying body-only on a 422) and the `CodeSage` check run. The check conclusion is error > failure > neutral (budget-limited only) > success. +- **Exit codes:** 0 when the review is published, whether the gate passed or tripped; 1 on an engine or publishing error. The check run is always completed. + +**Local mode** (`app/services/`, `app/api/`, `app/main.py`): +- **Lifespan:** opens LangGraph's `AsyncPostgresSaver` (psycopg v3, using `settings.checkpoint_dsn`, which is `DATABASE_URL` without `+asyncpg`) and marks rows stuck in `running` as `failed`. Without a checkpointer, reviews run in `report` mode and the gate can't pause. +- **`POST /reviews/async`:** `JobManager` runs `ReviewService.run_review_streamed` with `thread_id` = review id. A tripped gate interrupts the run and sets status `awaiting_approval`. PR mode means a PR number, no diff, and `GITHUB_TOKEN` set: the agents review a clone at the head, and the review can be posted. +- **`POST /reviews/{id}/decision`:** the `awaiting_approval → running` transition is atomic (409 otherwise). The review then resumes with `Command(resume=…)`. + - Approve posts to the PR. Posting is idempotent: a marker `` is checked via `list_reviews`. + - Reject posts nothing. + - A passing gate posts automatically. +- **Statuses:** `running`, `awaiting_approval`, `completed`, `rejected`, `failed`. +- **SSE** (`GET /reviews/{id}/stream`, backed by the in-process `ReviewBroker`, so a single Uvicorn worker only): + - Unknown or malformed ids return 404. + - Streams end on completed, failed or awaiting. + - A finished or paused review that's no longer buffered gets its final event rebuilt from the DB. + - `broker.reopen()` lets a resumed review continue the same stream, and buffers are evicted 10 minutes after the end. +- **Concurrency:** the reviewers run in parallel, so `semantic_search` (`app/rag/search.py`) opens its own session per call. Never share one `AsyncSession` across graph nodes. + +**Stage names live in five places.** If you add, rename or reorder graph nodes, update all of them: +- `STAGES` in `app/agents/graph.py`; `ReviewService.STAGE_ORDER` derives from it +- `STAGES` in `web/src/lib/format.ts` +- `STAGE_DEPS`/`STAGE_LABEL`/`OPTIONAL_STAGES` in `web/src/lib/useReviewStream.ts` +- `StageName` in `web/src/lib/types.ts` +- `ICONS` in `web/src/components/StageTimeline.tsx` + +The stream only reports completions, so the console derives running, pending, skipped and awaiting from the dependency map. + +**Security model:** +- **Auth:** `/api/v1` routes sit on `router` (`app/api/routes.py`) with `require_api_key` (`app/api/auth.py`, keys from `CODESAGE_API_KEYS`; it fails closed with 503). Only `/meta` is on `public_router`. New routes belong on `router`, and `tests/test_security.py` lists every protected route. +- **Console:** sends the key from localStorage and reads SSE via `fetch`. +- **Other limits:** API ingest is limited to `CODESAGE_INGEST_ROOTS`, and API eval datasets to `eval/datasets/`. Repo names go through `validate_repo` before any token-bearing call. +- **Logging:** goes to **stderr**, because stdout belongs to the MCP stdio transport. + +**Telemetry:** `BudgetGuard.record` prices each call from LangChain `usage_metadata`. Here `input_tokens` includes cached tokens, and cache writes appear either as `cache_creation` or as the `ephemeral_5m`/`ephemeral_1h` keys. It records into the review's `CostTracker` (`app/llm/telemetry.py`), which is persisted as `usage_events` rows plus the review's `telemetry` column. + +**Database schema has two sources of truth:** `migrations/*.sql` (idempotent, applied by `scripts/migrate.py` or on first boot) and the SQLAlchemy models in `app/db/models.py`.

Each runs a `create_agent` loop: Claude calls tools, observes the results, and finishes with a structured `Findings` object. The budget middleware tracks spend after every model call. +4. **Reflect.** The reflection agent sees all the draft findings (each with an `id` and a `reviewer`) and returns decisions. Code applies them, so attribution can't be lost, and findings are checked against the diff model. +5. **Judge.** Opus 5 scores the consolidated review. If the score is below the threshold and enough budget remains, the graph goes through `revise` (reflection again, given the judge's rationale) and back to the judge. This happens at most once. +6. **Gate.** The gate trips when any finding is critical or high, or when the score is below the threshold. In the Action this sets the check-run conclusion. Locally it calls `interrupt()` and waits for a decision. +7. **Publish.** One GitHub review with validated inline comments, plus the check run (Action) or a DB update and SSE event (local), plus a cost summary. + +## State + +The outer graph state (`app/agents/state.py`) keeps the current keys and adds: + +- `pr` (the `PRContext` dict), `budget_limited: bool`, `revision_count: int` +- `gate_tripped: bool`, `gate_reasons: list[str]`, `decision: "approved" | "rejected" | None`, `decision_note: str | None` (local mode, set on resume) +- `github_review_url: str | None` +- **Additive reducers:** `draft_findings`, `traces`. `_merge_delta` in `review_service.py` must list the same keys. +- Findings carry `id`, `reviewer`, `category`, `severity`, `confidence`, `path`, `line`, `end_line`, `title`, `rationale`, `suggestion` and `evidence`. + +Each reviewer's own message history lives inside its `create_agent` subgraph and isn't copied to the outer state; only its structured findings and trace are. + +## Cross-cutting rules + +- **Budget.** The $0.50 total is enforced by `BudgetGuard`, as set out in [design/01-agent-engine.md](design/01-agent-engine.md#budget). +- **Stub mode.** With no `ANTHROPIC_API_KEY`, reviewer, reflection and judge nodes use `app/llm/stub.py` and emit scripted traces.

The next call, carrying the thinking, tool-use and tool-result history, returned a valid `Findings` with the correct path and line. A full, unforced multi-step run wasn't paid for; Phase 4's manual run covers it. | +| 2 | Budget middleware strips tools (`request.override(tools=[])` plus a "finish now" message) → structured final answer | **Pass.** 2 calls: a tool call, then `end_turn` with a valid `structured_response`. The recipe is `awrap_model_call`: price `resp.result`'s `AIMessage.usage_metadata` after `handler()`; once over the allowance, override `tools=[]` before calling it. | +| 3 | `usage_metadata` token fields | **Pass, with a caveat.** `input_tokens` includes cached tokens. `input_token_details` has `cache_read`, `cache_creation`, `ephemeral_5m_input_tokens` and `ephemeral_1h_input_tokens`. When the TTL keys are present, langchain sets `cache_creation` to **0** and the writes are in the TTL keys, so pricing must use `cache_creation or (5m + 1h)`. 1h writes cost 2× input, 5m writes cost 1.25×. `output_token_details.reasoning` is also reported. Removing the tools changes the cached prefix, so the forced final call doesn't hit the cache. | +| 4 | Refusals | **Answered from source:** `ChatAnthropic` doesn't raise. `stop_reason` is in `response_metadata`, and `ProviderStrategy` parsing of a refusal raises `StructuredOutputValidationError`. The reviewer node checks `stop_reason == "refusal"` and raises a clear error. | +| 5 | `AsyncPostgresSaver` + `interrupt()` + `Command(resume=…)` across processes | **Pass** (pgvector container on port 5544). Process A stopped at the interrupt, and `__interrupt__` appeared in the `updates` stream with the payload. Process B resumed: the gate node re-ran from its start, then `publish` ran. Process C resumed the finished thread and got no updates; nothing re-ran. | + +**Dependency note:** unpinned, `langchain-anthropic` resolves `anthropic` 1.8.0 (1.x is out). The +approved pin `anthropic>=0.120,<1` resolves 0.125.0, which satisfies langchain-anthropic, so +the 1.x SDK upgrade stays out of scope for this round. + +## Open items for the Phase 1 spike (original list) + + +These have to pass against the live API before Phase 3 starts. If one fails, the +owner chooses the fallback. + +1. `create_agent` + `ChatAnthropic("claude-sonnet-5")` + tools + adaptive thinking + + `ProviderStrategy(Findings)` returns a valid `structured_response`. + **Fallback:** `ToolStrategy` with a final `submit_findings` tool, or a separate structured call after the loop. +2. `BudgetMiddleware` removing the tools in `wrap_model_call` produces a structured + final answer on the next call. **Fallback:** end the loop, then make one + structured "summarize your findings" call with the transcript. +3. `usage_metadata` gives the token fields listed above, so cost can be computed per call. +4. How `ChatAnthropic` surfaces `stop_reason == "refusal"`. +5. `AsyncPostgresSaver` + `interrupt()` + `Command(resume=…)` survives a process + restart with the upgraded `langgraph`. + +## Phase 4 verification (2026-09-24) + +The owner approved one paid run: the $0.02-budget case, on a throwaway clone with a planted +`os.system(input())` commit. It cost **$0.057** over 6 calls. + +- All three reviewers ran real tool loops: `read_file` and `search_code`. +- Each reviewer was forced to finish by the budget and still returned structured `Findings`. +- Every finding has the correct `reviewer` and is anchored at `app/api/debug.py:10`. +- Reflection and the judge were skipped for budget. `budget_limited` was set, and the gate reason + "budget-limited: not judged" was recorded. +- **Minimum cost per reviewer:** about $0.02, because it needs one investigation call plus the + forced final answer.
