Use `self.settings.skip_extensions`. Store the skipped count locally for the summary line — no need to thread it through config. (2) Remove `MAX_FILES = 100` cap in `_build_changed_files_section()` (line 212) — show ALL code files. Add a summary line for skipped non-code files count (passed as a parameter from `create_findings()`).

Add new instructions: "Review ALL files in your assigned batch — do not skip files. The orchestrator has already filtered non-code files and split the PR into manageable batches." and "When get_file_diff returns is_summary=true, the diff was too large to return in full.

(2) In `src/tools/workspace_tools.py`: raise search_code output truncation from 15000 to 25000 (line 104); raise read_local_file default max_lines from 500 to 1000 (line 148).

(2) Filter non-code files via `file_filter.filter_changed_files`. (3) Build graph once via `graph_builder.build_graph`. (4) If code files <= `settings.batch_size`, delegate to single-session `ReviewJob` (backward compatible shortcut). (5) Split into batches via `_split_into_batches()` using round-robin by churn descending. (6) Run each batch sequentially via `ReviewJob` with `file_subset`, `pre_built_graph`, `batch_index`, `batch_total`, and `max_turns=self.settings.batch_max_turns` set on `ReviewJobConfig` (this explicitly threads the per-batch turn budget from Settings into each batch's config). (7) Merge findings via `_merge_results()`: concatenate all findings, dedup by `(file, line, title)`, re-sequence cr-ids as `cr-001`, `cr-002`, ..., sum usage stats (input_tokens, output_tokens, duration), union review_modes. (8) Write merged `findings.json`. (9) If any batch fails, catch exception, log error, continue with remaining batches. - - `_split_into_batches(code_files, batch_size)`: sort by `additions + deletions` descending, round-robin distribute. - - `_merge_results(batch_results)`: dedup, re-sequence, sum usage. -- **Files:** `src/batch_review_job.py` (new) -- **Tier:** premium -- **Done when:** `BatchReviewJob` importable; `_split_into_batches` produces balanced batches; `_merge_results` re-sequences cr-ids and deduplicates; single-session shortcut works for <= batch_size files; failed batch handling doesn't crash; full `run()` method works end-to-end with mocked dependencies. -- **Blockers:** Tasks 2, 5 (file_filter + batch-aware ReviewJob). Risk: GraphStore reuse across batches. - -#### Task 8: Update run_agent.py, review prompt, and post_findings caps -- **Change:** (1) Modify `src/run_agent.py`: import `BatchReviewJob` from `batch_review_job`; construct it with CLI args instead of direct `ReviewJobConfig`/`ReviewJob`; call `batch_job.run(dry_run, commit_id)`. BatchReviewJob auto-delegates to single ReviewJob for small PRs — backward compatible. (2) Update `commands/review-pr-core.md`: In Step 4 T4/T5 rows, replace "Focus on highest-risk paths only" with "Review ALL files in your batch"; add note "Non-code files have been pre-filtered. You will only see code files."; add in Step 5: "When get_file_diff returns is_summary, drill into suspicious hunks with start_line/end_line." (3) In `src/post_findings.py`: replace module-level `MAX_TOTAL_FINDINGS = 30` → read from `get_settings().max_total_findings` (default 50); replace `MAX_PER_FILE = 5` → read from `get_settings().max_per_file_findings` (default 5). Update `cap_findings()` calls and `_build_summary_markdown` reference to use the dynamic values. -- **Files:** `src/run_agent.py`, `commands/review-pr-core.md`, `src/post_findings.py` -- **Tier:** standard -- **Done when:** `run_agent.py` uses `BatchReviewJob`; prompt no longer says "highest-risk paths only" for T4/T5; prompt includes smart diff drill-in guidance; `post_findings.py` reads caps from settings; existing tests pass. -- **Blockers:** Task 1 (Settings fields for `max_total_findings`/`max_per_file_findings`), Task 7 (BatchReviewJob must exist) - -#### VERIFY: Phase 3 — Orchestrator -- Run `pytest tests/` — all existing tests pass -- Verify `run_agent.py` imports and uses `BatchReviewJob` -- Verify `post_findings.py` reads caps from settings -- Verify review prompt updated with batch and smart diff guidance -- Report: tests passing, any regressions, any issues found - ---- - -### Phase 4: Tests (Depends on Phase 3) - -#### Task 9: Unit tests for file_filter and smart_diff -- **Change:** Create `tests/unit/test_file_filter.py`: test `parse_skip_extensions` with standard CSV, leading-dot normalization, mixed case, whitespace, empty string; test `filter_changed_files` keeps .py/.cs/.ts/.css, skips .md/.json/.yaml/.lock/.png, skips deleted files regardless of extension, handles empty list, handles all-skipped scenario.

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. - -### 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. - -**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. +| Item | Status | Notes | +|------|--------|-------| +| ReviewMode enum has FULL, VERIFY_FIXES, CHECK_NEW | PASS | `ReviewMode(str, Enum)` with correct values `"full"`, `"verify_fixes"`, `"check_new"` | +| review_mode threaded through ReviewJobConfig | PASS | `review_mode: ReviewMode = ReviewMode.FULL` field present, default correct | +| review_mode threaded through BatchReviewJob.__init__ | PASS | Accepted as kwarg, stored as `self.review_mode` | +| CLI flags mutually exclusive via argparse | PASS | `add_mutually_exclusive_group()` used; passing both flags raises argparse error | +| CHECK_NEW mode skips _fetch_previous_findings() | PASS | `batch_review_job.py:88-90` — conditional skip with log message | +| review_mode passed to ALL ReviewJobConfig constructors | PASS | Both single-session path (line 117) and batched path (line 252) include `review_mode=self.review_mode` | +| No regressions in existing behavior | PASS | 190 tests pass, 13 skipped (same as baseline) | +| Code quality consistent with existing patterns | PASS | See notes below | --- -## Task 8: Update run_agent.py, review prompt, and post_findings caps - -### 8.1 -- run_agent.py (src/run_agent.py) - -**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. - -**NOTE:** The `vcs` parameter is not passed to `BatchReviewJob` -- it defaults to `"ado"`.

Added note: "Non-code files have been pre-filtered by the orchestrator." **PASS.** -2. **Step 5 strategy table updated**: T4 and T5 rows now say "Review ALL files in your batch" with graph priority guidance. **PASS.** -3. **Smart diff drill-in guidance** (Step 5a): Added paragraph explaining `is_summary: true` response and how to use `start_line`/`end_line` to drill in. **PASS.** +3. **BatchReviewJob** (`src/batch_review_job.py:46`): `review_mode` parameter follows the same default pattern. The CHECK_NEW conditional (lines 88-93) is clear and correctly placed before `_fetch_previous_findings()`. -### 8.3 -- post_findings.py caps from settings +4. **CLI** (`src/run_agent.py:31-43`): `add_mutually_exclusive_group()` is the correct argparse pattern. Flag-to-enum resolution (lines 46-52) is straightforward. The `review_mode` is correctly passed to the `BatchReviewJob` constructor. -**PASS.** All changes correct: - -1. **Module-level defaults updated** (lines 31-32): `MAX_TOTAL_FINDINGS` changed from 30 to 50 (matching `settings.max_total_findings` default). `MAX_PER_FILE` stays at 5. Both annotated with comments explaining runtime override. **PASS.** -2. **Runtime settings read** (lines 700-702): `max_total = settings.max_total_findings if settings else MAX_TOTAL_FINDINGS` and same pattern for `max_per_file`. Clean fallback when settings unavailable. **PASS.** -3. **`cap_findings()` call** (line 702): Passes dynamic `max_total` and `max_per_file`. **PASS.** -4. **`_build_summary_markdown` updated** (line 518): Accepts `max_total_findings` parameter, uses it in the "Total posted: X / Y max" summary line. Caller passes `max_total`. **PASS.** - -**NOTE:** The `cap_findings()` function signature still has module-level constant defaults. These are only triggered if called without arguments (e.g., from tests). The `run()` function always passes explicit values. Correct and safe. **PASS.** +5. **Consistency**: Both `ReviewJobConfig` constructors in `BatchReviewJob` (single-session at line 105 and batched at line 237) correctly pass `review_mode=self.review_mode`. --- -## Test Results - -``` -136 passed, 2 failed, 13 skipped, 42 warnings in 4.69s -``` +## Observations (non-blocking) -- **2 pre-existing failures** (confirmed on main): - - `test_prints_diagnostic_on_failure` in `test_graph_builder.py` -- expects `print()` but code uses `logger.warning()` - - `test_still_present_not_resolved_ado` in `test_post_findings.py` -- `activities` module import path issue -- **No new failures introduced.** **PASS.** +- The standalone `create_findings()` path in `ReviewJob` (lines 715-726) still fetches previous findings when `previous_findings is None`, regardless of `review_mode`. This is acceptable for Phase 1 since the CHECK_NEW guard is in `BatchReviewJob.run()` which is the primary entry point. Phase 2 (Task 3) will add the mode-conditional guard inside `ReviewJob.create_findings()` as specified in the plan. --- ## Summary -Phase 3 (Tasks 7 and 8) is **APPROVED**. 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. +Phase 1 is correctly implemented. The `ReviewMode` enum is well-structured, properly threaded through config and CLI, flags are mutually exclusive, and CHECK_NEW mode correctly skips previous findings fetch in the batch orchestrator. All 190 existing tests pass with no regressions. Ready to proceed to Phase 2.

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. + +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. + +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). + +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. + +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. + +--- + +## Observations (non-blocking) + +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. + +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. + +--- + +## Summary + +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).

The `ReviewMode` enum is well-structured, prop ## Summary 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.

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. No regressions, no security issues, no blocking findings. **APPROVED for merge.**
