Exception handling returns `None` on failure. **PASS.** -2. **Filter non-code files** (lines 66-71): Uses `parse_skip_extensions` + `filter_changed_files` with `self.settings.skip_extensions`. Logs kept/skipped counts. **PASS.** -3. **Build graph once** (line 74): Calls `_build_graph()` with `changed_file_count`. Graph built once and shared across batches via `pre_built_graph`. Exception handling returns `None` on failure. **PASS.** -4. **Single-session shortcut** (lines 77-93): When `len(code_files) <= self.settings.batch_size`, creates a `ReviewJobConfig` with `file_subset` and `pre_built_graph`, delegates to `ReviewJob.run()`. Backward compatible. **PASS.** -5. **Batch splitting** (line 96): Calls `_split_into_batches()`. **PASS.** -6. **Sequential batch execution** (lines 101-116): Iterates batches, calls `_run_batch()`, catches exceptions per-batch so failures don't crash the pipeline. **PASS.** -7. **Merge findings** (line 119): Calls `_merge_results()`. **PASS.** -8. **Write merged findings.json and publish** (lines 123-139): Writes to `.cr/findings.json`, then calls `post_findings.run()`. **PASS.** +## Code Quality Notes -### 7.3 -- `_split_into_batches()` correctness (lines 199-223) +1. **create_findings() guard** (`review_job.py:89`): Clean single-line condition addition. The `CHECK_NEW` guard at both the `BatchReviewJob` level (Phase 1) and the standalone `ReviewJob` level (Phase 2) provides complete coverage — addresses the Phase 1 observation. -**PASS.** Round-robin by churn descending: -- Sorts by `(additions + deletions)` descending with `hasattr` guard for non-FileChange objects. -- Computes `num_batches` using ceiling division: `(len + batch_size - 1) // batch_size`. -- Distributes via `batches[i % num_batches]` -- this correctly interleaves high-churn and low-churn files for balanced workload. -- Returns empty list for empty input. +2. **Prompt injection** (`review_job.py:450-453`): Mode instructions are appended after `previous_findings` section and before config section, which is the correct position — the agent sees mode constraints immediately after the prior findings table. Both instruction methods use bold headers and imperative language. -**NOTE:** Ceiling division matches the PLAN.md `ceil(len / batch_size)` requirement without importing `math.ceil`. Correct. +3. **Defense-in-depth** (`review_job.py:539-548`): `setdefault` for review_modes is defensive against missing keys. Strips the correct field for each mode and ensures the mode tag is present in review_modes for downstream consumers (post_findings). -### 7.4 -- `_merge_results()` correctness (lines 225-282) +4. **post_findings verify-only detection** (`post_findings.py:816`): Uses `not findings_file.findings` rather than checking review_modes alone — this means a VERIFY_FIXES run where the agent somehow produced findings (before write guards strip them) would still be detected correctly by the double condition. Good defensive design. -**PASS.** Dedup and re-sequence: -- Concatenates all findings from batch results. -- Dedup by `(file, line, title)` tuple -- matches PLAN.md spec. Preserves first occurrence. -- Re-sequences cr-ids as `cr-001`, `cr-002`, ... using `f"cr-{i:03d}"`. **PASS.** -- Sums `input_tokens`, `output_tokens`, `duration_seconds`. **PASS.** -- Unions `review_modes` via set, sorted for deterministic output. **PASS.** -- Uses last non-empty `model` string (reasonable for homogeneous batches). **PASS.** +5. **Gate bypass** (`post_findings.py:897-898`): Hard-coded pass is correct — verify-only runs have no findings to gate on. The gate still loads .codereview.yml (line 896) which is slightly wasteful but harmless. -### 7.5 -- `batch_max_turns` threading (line 182) +--- -**PASS.** `_run_batch()` explicitly sets `max_turns=self.settings.batch_max_turns` on the `ReviewJobConfig`. This correctly threads the per-batch turn budget from Settings into each batch's config. The single-session shortcut (line 82) does NOT set `max_turns`, so it inherits the default (40) from `ReviewJobConfig` -- correct since single-session reviews should use the standard budget. +## Observations (non-blocking) -### 7.6 -- GraphStore reuse safety +1. **Duplicate step number comment** (`post_findings.py:895,902`): Steps 11 and 12 in the `run()` function both start at `# 11.` after the Phase 2 renumbering. The second `# 11` (line 902) should be `# 12`. Cosmetic only — no logic impact. -**PASS.** The graph is built once in `_build_graph()` and passed as `pre_built_graph` to each batch's `ReviewJobConfig`. In `review_job.py` (lines 108-110), when `pre_built_graph` is set it is used directly without modification. The graph is read-only during review (agents query it via `get_callers`, `get_blast_radius`, etc.) so sequential reuse across batches is safe. +2. **Scoring still runs for verify-only** (`post_findings.py:870-871`): `apply_mode_multipliers` and `calculate_pr_score` run on the empty `capped` list, producing a perfect 5-star score. This is correct behavior (no penalty deductions = best score), but the score is somewhat meaningless for verify-only runs. The summary title already disambiguates this for users. -### 7.7 -- Error handling +--- -**PASS.** Three levels of resilience: -- `_fetch_pr_details()`: catches all exceptions, returns `None`, logs warning. When `None`, `all_files = []` (line 62). -- `_build_graph()`: catches all exceptions, returns `None`, logs warning. -- Per-batch execution (lines 114-116): catches all exceptions, logs error, continues with remaining batches. -- If all batches fail, `_merge_results([])` returns a clean empty result. +## Summary -**NOTE:** When `pr_details` is `None` (pre-fetch failed), `all_files = []`, so `code_files = []`, and the method proceeds to the single-session shortcut with an empty file list. The `ReviewJob` will skip its own pre-fetch (since `file_subset=[]` is not `None`). Acceptable -- the agent receives an empty file list, no worse than the pre-fetch failure itself. +Phase 2 is correctly implemented. All three components — prompt injection, write guards, and post_findings mode awareness — work together as a defense-in-depth chain: the prompt tells the agent what to do, write guards enforce it regardless of agent compliance, and post_findings adapts its behavior to the resulting mode-tagged findings file. FULL mode code paths are untouched. All 190 existing tests pass with no regressions. Ready to proceed to Phase 3 (tests). --- -## Task 8: Update run_agent.py, review prompt, and post_findings caps +# Review Modes — Phase 3 (Cumulative) Code Review -### 8.1 -- run_agent.py (src/run_agent.py) +**Reviewer:** local-codehawk-reviewer +**Date:** 2026-05-08 +**Verdict:** APPROVED -**PASS.** Clean transition from `ReviewJob` to `BatchReviewJob`: -- Imports `BatchReviewJob` from `batch_review_job` (line 12). -- Constructs with CLI args: `pr_id`, `repo`, `workspace`, `model`, `prompt_path` (lines 29-35). -- Calls `job.run(dry_run=..., commit_id=...)` (line 38). -- Handles gate failure via `sys.exit(1)` (lines 40-41). -- Backward compatible: `BatchReviewJob` delegates to single `ReviewJob` for small PRs. +> Cumulative review covering all three phases: Foundation, Conditional Behavior, and Tests. -**NOTE:** The `vcs` parameter is not passed to `BatchReviewJob` -- it defaults to `"ado"`.

The BatchReviewJob orchestrator correctly implements all requirements: - -- `_split_into_batches` produces balanced batches via round-robin by churn descending -- `_merge_results` deduplicates by (file, line, title) and re-sequences cr-ids correctly -- Single-session shortcut works for small PRs (backward compatible) -- GraphStore safely shared read-only across batches -- Failed batches don't crash the pipeline -- `batch_max_turns` correctly threaded into per-batch `ReviewJobConfig.max_turns` -- `run_agent.py` cleanly transitions to `BatchReviewJob` -- `post_findings.py` reads caps from settings at runtime with safe fallbacks -- Review prompt updated with batch and smart diff guidance -- No regressions in Phase 1 or Phase 2 -- 136 tests pass, 2 pre-existing failures unchanged - -**Carried forward (non-blocking):** `smart_diff.py:63` boundary operator (`<=` should be `<`). To be addressed in Phase 4 unit tests. +The Review Modes feature is complete and correct across all three phases. The implementation follows a clean defense-in-depth pattern: CLI flags → enum threading → prompt injection → write guards → post_findings mode detection. Each layer operates independently, so even if the AI agent ignores prompt instructions, the write guards enforce the contract. All 221 tests pass (31 new + 190 original), coverage exceeds requirements (31 tests vs. 15 minimum), and all 8 acceptance criteria from requirements.md are satisfied.
