The only PERSISTENT output is the review file (the helper-derived `review_path` in `~/.claude/plans/` — its filename carries a canonical-path digest). The workflow also uses invocation-scoped TEMPORARY files, which are allowed: the ingress/scratch files under `$(git rev-parse --git-path plan-review)` (inside `.git/`, never project content) and the helper-managed snapshot/state/meta/body files under `~/.claude/plans/.snapshots/` (the helper deletes them on persist and on abort). -- **Advisory-only**: Provide feedback and recommendations. Do not implement fixes. -- **No code changes**: Do not modify any source code, test files, or documentation. -- Use the Read tool for files and the Glob/Grep tools for searching. Do not use Edit, NotebookEdit, or file-modifying Bash commands on project files. The Write tool and `mkdir -p` may target only `~/.claude/plans/` and the two temporary locations above. -- The `gh api` calls used with `--pr` are read-only API requests, consistent with the project-files read-only constraint. - -## Instructions - -### Step 1: Take an Immutable Snapshot of the Plan - -**The review must certify exactly the bytes it examined.** The whole -snapshot/verify/persist protocol lives in the tested helper -`.claude/scripts/plan_snapshot.py` (see `tests/test_plan_snapshot.py`) — the -raw plan path is UNTRUSTED and never touches a shell; it reaches the helper -via a file written with the Write tool: - -1. Derive the scratch dir (one Bash call; deterministic, worktree-correct): - ```bash - SCRATCH="$(git rev-parse --git-path plan-review)" - mkdir -p "$SCRATCH" && echo "$SCRATCH" - ``` -2. **Write the raw plan path** (exactly as supplied, `~` and all) to - `/plan-path.txt` with the Write tool — never `echo`/heredoc. -3. **Run the helper** (re-derive `SCRATCH` in this call): - ```bash - SCRATCH="$(git rev-parse --git-path plan-review)" - python3 .claude/scripts/plan_snapshot.py snapshot --plan-path-file "$SCRATCH/plan-path.txt" - ``` - It normalizes the path as data (`~` expansion, canonical realpath — any - absolute path is accepted; the path never touches a shell), reads the plan - bytes ONCE, - writes an invocation-unique immutable snapshot + state token, and prints - JSON: `state_path`, `snapshot_path`, `meta_path`, `body_path`, `plan_path`, - `plan_sha256`, `review_path`. Non-zero exit = invalid/unreadable path — - report its message and stop. **Confirm the printed `plan_path` is the plan - you supplied** (a concurrent session overwriting the ingress file is - thereby detected — if it differs, re-run from step 2). -4. **Read the SNAPSHOT file** (Read tool, the printed `snapshot_path`) — it is - the ONLY text this review examines. The state token keys the rest of the - protocol; Step 6's persist certifies the RECORDED snapshot digest only - after re-verifying the live plan against it. **If the review aborts for any - reason before persisting** (error, user cancellation), clean up the - invocation: `python3 .claude/scripts/plan_snapshot.py abort --state-file - ""` — temporary snapshot files must not accumulate. - -### Step 1b: Handle Re-Review (if `--updated`) - -If the `--updated` flag is present, this is a re-review of a revised plan. - -**You MUST perform a complete fresh review** — do not skip or abbreviate any steps. Treat the plan file contents as the authoritative source, not your memory of a prior version. - -After completing the standard 8-dimension review in Step 4, add a **Delta Assessment** section to the output (see Step 5 template for format). This section compares the revised plan against the prior review's feedback: -- Which previously-raised issues have been addressed? -- Which previously-raised issues remain unresolved? -- Are there any new issues introduced by the revisions? - -Additionally, check for a prior review via the Step 1 snapshot output: its `review_path` is the canonical location (review filenames carry a canonical-path digest — never derive them from the basename). If a file exists there, read it as a supplementary source of prior review context. When conversation context has been compressed between rounds, use the review file's content for delta assessment instead. If both conversation context and the review file are available, prefer whichever source is more detailed. - -If no prior review is available from either source (conversation context or review file), still include the Delta Assessment section but fill each subsection with: "Delta assessment unavailable — no prior review found in conversation context or review file. Full fresh review performed." - -### Step 2: Read CLAUDE.md for Project Context - -Read the project's `CLAUDE.md` file to understand: -- Key design patterns (sklearn-like API, formula interface, results objects, etc.) -- Estimator inheritance map -- Testing conventions -- Key reference file pointers (methodology registry, etc.) - -Also read `CONTRIBUTING.md` for documentation requirements, test writing -guidelines, and implementation guidelines. - -If the plan modifies estimator math, standard error formulas, inference logic, or edge-case handling, also read `docs/methodology/REGISTRY.md` to understand the academic foundations and reference implementations for the affected estimator(s). - -### Step 2b: Parse Comment URL and Verify Branch (if `--pr`) - -Only perform this step when `--pr ` was provided. Otherwise skip to Step 3. - -**Parse the URL:** -- Strip query parameters from the URL before parsing: remove the query string (the `?...` portion) while preserving the `#` fragment. For example, `https://github.com/o/r/pull/1?notification_referrer_id=abc#issuecomment-123` becomes `https://github.com/o/r/pull/1#issuecomment-123`. If the fragment itself contains `?` (e.g., `#discussion_r123?foo=bar`), strip the `?` and everything after it from the fragment before pattern matching, since GitHub fragments never contain `?` as meaningful data. -- Only `github.com` URLs are supported. If the URL host is not `github.com`, report an error and stop. -- Extract `owner`, `repo`, `pr_number` from the URL path. The `pr_number` is always the path segment immediately after `/pull/`. -- Extract comment type and ID from the fragment: - -| Fragment | Type | `gh api` endpoint | -|---|---|---| -| `#issuecomment-{id}` | Issue comment | `repos/{owner}/{repo}/issues/comments/{id}` | -| `#discussion_r{id}` | Inline review comment | `repos/{owner}/{repo}/pulls/comments/{id}` | -| `#pullrequestreview-{id}` | PR review | `repos/{owner}/{repo}/pulls/{pr_number}/reviews/{id}` | - -If the URL doesn't match any fragment pattern (including bare PR URLs without a fragment), report: -``` -Error: Unrecognized PR comment URL format. Expected a GitHub PR comment URL like: - https://github.com/owner/repo/pull/123#issuecomment-456 -The URL must point to a specific comment, not a PR page. -``` - -**Verify `gh` CLI availability:** - -Run `gh auth status 2>/dev/null` (suppress output on success). If it fails, report a hard error: -``` -Error: The --pr flag requires the GitHub CLI (gh) to be installed and authenticated. -Run `gh auth login` to authenticate, then retry. -``` - -**Verify branch state:** - -```bash -gh pr view --repo / --json headRefName,baseRefName,title --jq '.' -``` - -Compare `headRefName` against `git branch --show-current`: -- **Match**: Note "Branch verified" in output. -- **Mismatch**: Emit a warning in the output and note under Dimension 2 (Codebase Correctness) that code references may be inaccurate. Recommend the user checkout the PR branch first (`git checkout `), but do not block the review. - -### Step 2c: Fetch the Specific Comment (if `--pr`) - -Only perform this step when `--pr` was provided. Otherwise skip to Step 3. - -Fetch the comment using the `gh api` endpoint from the table in Step 2b. - -**For `pullrequestreview-` URLs**, fetch BOTH the review body AND its inline comments: -```bash -# Review body -gh api repos/{owner}/{repo}/pulls/{pr_number}/reviews/{id} --jq '{body: .body, user: .user.login, state: .state}' - -# All inline comments belonging to this review -gh api repos/{owner}/{repo}/pulls/{pr_number}/reviews/{id}/comments --paginate --jq '.[] | {body: .body, path: .path, line: .line, diff_hunk: .diff_hunk}' -``` - -**For other comment types**, fetch the single comment: - -**Issue comment:** -```bash -gh api repos/{owner}/{repo}/issues/comments/{id} --jq '{body: .body, user: .user.login, created_at: .created_at}' -``` - -**Inline review comment:** -```bash -gh api repos/{owner}/{repo}/pulls/comments/{id} --jq '{body: .body, user: .user.login, path: .path, line: .line, diff_hunk: .diff_hunk}' -``` - -**Error handling:** -- **404**: `Error: Comment not found at . It may have been deleted or the URL may be incorrect.` -- **403 / other API errors**: `Error: GitHub API returned . You may not have access to this repository, or you may be rate-limited. Check 'gh auth status' and try again.` -- **Empty comment body** (and no inline comments for review types): report and skip Dimension 9: - ``` - Note: No feedback text found in the comment at . - Skipping PR Feedback Coverage (Dimension 9). Reviewing plan without PR context. - ``` - -The response includes: `body` (comment text), `user.login` (author), `created_at`, and for inline comments: `path` (file), `line` (line number in the file — use `line`, not `position` which is the diff offset, and not `original_line` which is the base branch line), `diff_hunk` (surrounding diff context). - -**Extract discrete feedback items** from the comment body: -- For AI review comments (structured markdown with P0/P1/P2/P3 or Critical/Medium/Minor sections): parse each severity section and extract individual items with their labeled severity -- For human comments with numbered/bulleted lists: each list item is one feedback item -- For human comments that are a single paragraph or conversational: the entire comment is one feedback item -- For inline review comments: each comment is one item, with `path` and `line` as its file/line reference -- **Default severity**: when a feedback item has no severity label, treat it as Medium -- Process all feedback items regardless of count - -Each feedback item tracks: severity (labeled or default Medium), description, file path (if available), and line reference (if available). - -### Step 3: Read Referenced Files - -Identify all files the plan references (file paths, module names, class names). When `--pr` was provided, also include files referenced in the feedback comment — inline comment `path` fields and file paths mentioned in the comment body (e.g., `path/to/file.py:L123`). Then read them to validate the plan's assumptions: - -**Priority order for reading files:** -1. **Files the plan proposes to modify** — read ALL of these first -2. **Files referenced for context** (imports, call sites, existing patterns) — read selectively to verify specific claims - -**Scope restriction:** -- Only read files that are within the project repository (the working directory tree). -- The plan file itself (the `$ARGUMENTS` input) is exempt — it can be anywhere (e.g., `~/.claude/plans/`). -- If the plan references paths outside the repo (home directory configs, SSH keys, `/etc/` files, etc.), do NOT read them. Instead, note in the review output under Dimension 2 (Codebase Correctness) that those external paths were not verified. - -**What to verify:** -- File paths exist -- Class names, function signatures, and method names match what the plan describes -- Line numbers (if referenced) are accurate -- The plan's description of existing code matches reality - -If the plan references more than ~15 files, use judgment: read all files slated for modification, then spot-check context files as needed rather than reading every one. - -### Step 4: Evaluate Across 8 Dimensions - -#### Dimension 1: Completeness & Executability - -Could a fresh Claude Code session — with no access to the conversation history that produced this plan — execute it without asking clarifying questions? - -Check for: -- Are all file paths explicit? (No "the relevant file" or "the test file") -- Are code changes described concretely? (Function signatures, parameter names, not just "add a method") -- Are decision points resolved, not deferred? ("We'll figure out the API later" is a red flag) -- Are there implicit assumptions that require conversation context to understand? - -#### Dimension 2: Codebase Correctness - -Do file paths, class names, function signatures, and line-number references in the plan match the actual codebase? - -Use your findings from Step 3. Flag: -- File paths that don't exist -- Function/class names that are misspelled or don't exist -- Line numbers that point to the wrong code -- Descriptions of existing behavior that don't match reality - -#### Dimension 3: Scope - -Is the scope right — not too much, not too little? - -Check for **missing related changes**: -- Tests for new/changed functionality -- `__init__.py` export updates -- `get_params()` / `set_params()` updates for new parameters -- Documentation updates (`diff_diff/guides/llms.txt` for new public-API surfaces, `docs/api/*.rst`, `docs/references.rst` for new citations, tutorials, CONTRIBUTING.md, CLAUDE.md if design patterns change). README updates only if the change affects the landing page (new estimator catalog one-liner, hero/badges/tagline, top-level capability paragraph) - per CONTRIBUTING.md, README is not the place for usage examples or per-estimator sections. -- For bug fixes: did the plan grep for ALL occurrences of the pattern, or just the one reported? - -Check for **unnecessary additions**: -- Docstrings/comments/type annotations for untouched code -- Premature abstractions or over-engineering -- Feature flags or backward-compatibility shims when the code can just be changed - -#### Dimension 4: Edge Cases & Failure Modes - -For methodology-critical code: -- NaN propagation through ALL inference fields (SE, t-stat, p-value, CI) -- Empty inputs / empty result sets -- Boundary conditions (single observation, single group, etc.) -- **Registry cross-check** (for plans modifying estimator math/SE/inference): - - Read the relevant estimator section in `docs/methodology/REGISTRY.md` - - For each equation the plan implements: verify it matches the Registry, or the plan documents the deviation - - For each edge case in the Registry's "Edge cases" section: verify the plan handles it or explicitly defers it - - CRITICAL if plan contradicts a Registry equation without documented deviation - - MEDIUM if plan doesn't handle a documented Registry edge case - - LOW if plan adds new edge case handling not yet in Registry (suggest updating it) - -For all code: -- Error handling paths — are they tested with behavioral assertions (not just "runs without exception")? -- What happens when the feature interacts with other parameters/modes? - -#### Dimension 5: Architecture & Patterns - -Check against CLAUDE.md conventions: -- Does it respect the estimator inheritance map? (Adding a param to `DifferenceInDifferences` auto-propagates to `TwoWayFixedEffects` and `MultiPeriodDiD`; standalone estimators need individual updates) -- Does it use `linalg.py` for OLS/variance instead of reimplementing? -- Does it follow the sklearn-like `fit()` / results-object pattern? -- Is there a simpler alternative that avoids new abstraction? -- Does it match existing code patterns in the codebase? - -#### Dimension 6: Plan Execution Risks - -Plan-specific failure modes that wouldn't show up in a code review: - -- **Ordering issues**: Does the plan propose changes in an order that would break things mid-implementation? (e.g., changing an import before the module it imports from exists, deleting a function before updating its callers) -- **Ambiguous decision points**: Does the plan defer decisions that should be made now? Vague phrases like "choose an appropriate approach" or "handle edge cases" without specifying which ones -- **Missing rollback path**: For risky changes (public API modifications, data format changes), does the plan consider what happens if something goes wrong? -- **Implicit dependencies**: Does step N assume step M was completed, but this ordering isn't stated? - -#### Dimension 7: Backward Compatibility & API Risk - -- Does the plan add, remove, or rename public API surface (parameters, methods, classes)? -- If so, does it acknowledge the breaking change and state the versioning decision (deprecation period vs clean removal)? -- Downstream effects on: - - Convenience functions - - Re-exports in `__init__.py` - - Existing tutorials and documentation - - User code that may depend on the current API - -#### Dimension 8: Testing Strategy - -- Are tests included in the plan? Do they cover the happy path AND the edge cases from Dimension 4? -- Are test assertions behavioral (checking outcomes) rather than just "runs without exception"? -- For bug fixes: does the plan fix all pattern instances and test all of them? -- Are there missing test scenarios? (Parameter interactions, error paths, boundary conditions) - -#### Dimension 9: PR Feedback Coverage (only if `--pr` provided with non-empty comment) - -Only evaluate this dimension when `--pr` was provided and a non-empty comment was fetched in Step 2c. For each feedback item extracted in Step 2c, assess: - -- **Addressed**: Plan explicitly mentions the issue AND proposes a concrete fix -- **Partially addressed**: Plan touches the area but doesn't fully resolve the feedback -- **Not addressed**: Plan makes no mention of this feedback item -- **Dismissed with justification**: Plan acknowledges the feedback but explains why it won't be acted on (acceptable for Low/P3; flag for Critical/P0) - -Use judgment, not just substring matching — the plan may use different words to describe the same fix. - -**Assessment impact:** -- Unaddressed P0/P1/Critical items -> results in "Significant issues found" -- Unaddressed P2/Medium items count as Medium issues -- Unaddressed P3/Low items count as Low issues - -### Step 4b: Display Plan Content - -Before presenting the review, display the full plan content so the user can cross-reference the review findings against what was actually written: - -``` -## Plan Content: - - - ---- -``` - -This ensures the user can read the plan immediately before reading the review findings. Display the full plan content as-is from the file. - -Note: The plan content is displayed in the terminal only — it is NOT included in the `.review.md` file (Step 6), which contains only the review output. The plan is already persisted as its own file. - -### Step 5: Present Structured Feedback - -Present the review in the following format. Number each issue sequentially within its severity section (e.g., CRITICAL #1, CRITICAL #2, MEDIUM #1) to enable cross-referencing with `/revise-plan`. Do NOT skip any section — if a section has no findings, write "None." for that section. The Delta Assessment section is only included when the `--updated` flag was provided (see Step 1b). The PR Context and PR Feedback Coverage sections are only included when `--pr` was provided with a non-empty comment. - -``` -## Overall Assessment - -[2-3 sentences: what the plan does, the reviewer's key observations, and the biggest concern if any] - ---- - -## PR Context (only include if `--pr` was provided with non-empty comment) - -**PR**: # - (<owner>/<repo>) -**Branch**: <headRefName> -> <baseRefName> -**Comment**: <comment-url> -**Comment author**: <user.login> -**Feedback items extracted**: N -**Branch match**: Yes / No (warning: recommend `git checkout <headRefName>`) - ---- - -## Issues - -### CRITICAL -[Issues that would cause implementation failure, incorrect results, or breaking changes if not addressed.

If they disagree, or there are no findings AND no parseable table, the +report is malformed — do NOT persist a guessed assessment: `abort` (plain — the +state still exists; it also removes the `work_dir`) and report the malformed +output. Otherwise derive the label from the line counts **by this deterministic +rule** (so identical findings always persist the same label): + +- any **P0 or P1** → `Significant issues found` +- else any **P2** → `Minor revisions recommended` +- else (only P3, or no findings) → `Ready to implement` + +Then write the meta JSON to `meta_path`: + +```json +{"reviewed_at": "<ISO-8601 UTC>", "assessment": "<Ready to implement | Minor revisions recommended | Significant issues found>", "critical_count": <P0>, "medium_count": <P1+P2>, "low_count": <P3>, "flags": []} +``` + +Then `python3 .claude/scripts/plan_snapshot.py persist --state-file "<state_path>"` +(exit 0 = stamped + cleaned up, `work_dir` included; exit 3 = plan changed +mid-review → re-review; other non-zero → report). **Do NOT abort after persist** +— `persist` self-cleans the entire invocation (snapshot + `work_dir` + sidecars) +on ANY failure, so post-persist there is nothing left to release, and a +follow-up abort could only ever hit a wrong/stale token. There is no separate +`rm -rf` at any point — persist and abort both remove the `work_dir`. Display the +review in the conversation. + +### 8. Surface the verified findings (advisory — do NOT edit the plan here) + +The review is now persisted and stamps the CURRENT plan bytes, so the approval +gate is satisfied for the plan as-is. **Editing the plan now would invalidate +that stamp and re-deny `ExitPlanMode`** (the hook compares `plan_sha256` to the +live bytes). So this step only PRESENTS the merged review to the user and +changes nothing on disk. + +Acting on the findings is the **Revise phase** (below): it applies edits and +re-reviews, which re-stamps the hash. Carry the triage directive there — when +the user opts to revise, each verified finding is either a **mechanical fix +applied directly** (a stale path, a missing test, a signature the plan can just +adopt) or a **genuine trade-off surfaced with options + a recommendation**, +never a judgment call silently written into the plan. + +--- + +## Revise phase + +Consumes the review artifact and applies revisions, then re-reviews. The +re-review re-runs the **Review phase in the SAME engine mode the existing review +used** — read from the review's `<!-- plan-review-engine: … -->` marker +(step 2). Never silently upgrade a deliberate-`single` review to dual, and never +fall back to a retired single-reviewer path. + +1. **Locate the review** via the helper (review filenames carry a canonical + path digest — never derive from the basename). Derive + print the scratch dir + (`SCRATCH="$(git rev-parse --git-path plan-review)"; mkdir -p "$SCRATCH"; echo + "$SCRATCH"`), then with the **Write tool** write the plan path to the printed + `<scratch>/plan-path.txt` (a literal, not a `$SCRATCH` token — Write does not + expand variables), then run (re-deriving the path inline) + `python3 .claude/scripts/plan_snapshot.py check --plan-path-file "$(git rev-parse --git-path plan-review)/plan-path.txt"` + → `plan_path`, `review_path`, `review_exists`, `fresh`. Confirm the printed + `plan_path` matches (shared ingress). + - `review_exists` false → run the **Review phase** first (nothing to revise + from). + - `review_exists` true but `fresh` false → the plan bytes already changed + since the review was stamped, so the review describes stale content. Do + NOT revise from it: re-run the **Review phase** over the current plan + first, then revise from that fresh review. +2. **Display** the plan + review in the conversation. **Parse** issues by + severity (CRITICAL/MEDIUM/LOW ↔ P0 / P1+P2 / P3) and checklist gaps, and read + the review's **engine mode** from its provenance marker + `<!-- plan-review-engine: … -->`: `single` ⇒ deliberate single; + `single-fallback` or `dual` ⇒ dual (a fallback re-review retries codex, which + is desired). Older reviews without the marker fall back to prose (a + deliberate-single note ⇒ single, otherwise dual). Use this for the re-review + in step 4. +3. **Apply revisions** to the plan file (triage rule from step 8). +4. **Re-review**: the plan bytes changed, so the stamped review is now stale — + re-run the **Review phase** over the revised plan **in the engine mode noted + in step 2** (a fresh review writes the new `plan_sha256`). If the user + declines the re-review, write an honest **Skipped** marker instead: snapshot, + then persist with meta + `{"reviewed_at": "<ISO 8601>", "assessment": "Skipped", "critical_count": 0, + "medium_count": 0, "low_count": 0, "flags": []}` and body `Review skipped by + user.` — never re-stamp the old review's hash onto unexamined content.

What survives all of that is the **sensitivity** result (dual +7/9 vs single 1/9, 0 regressions B→C), which is what selects dual as the +default. The engine shipped to `.claude/skills/plan-review/` is arm C **as run** +(candidate criteria + dual); a clean re-validation is a tracked follow-up.

All 4 hallucinations came from the dual +arms; every single arm was 0%. But the dual arm's 33 findings beyond +single-candidate B were **31 true, 2 false** — the extra volume is +overwhelmingly real. 3 of the 4 false findings were one systematic +overstatement (mis-citing a CONTRIBUTING.md tutorial requirement as a mandate). + +## Recommendation (exploratory — see Status) + +On the sensitivity signal, ship **arm C as run: candidate criteria + dual review +(Claude @ Opus 4.8 + codex-sol @ xhigh) + merge/verify**. Dual is a ~7× +sensitivity gain over any single reviewer at a ~3.4% hallucination cost — +favorable, since a false finding costs a dismissal while a missed defect costs a +bad plan. This is a directional pick from a NON-GATING campaign, not a validated +verdict: the candidate criteria carry the `trop-silent-drop` regression and the +FP axis on a genuinely-clean plan is unmeasured (both tracked). A clean +re-validation is the path to a gating result. + +## Methodology lesson — negative controls + +The 3 `s3_negative` plans were selected because their *implementations* passed +CI code review — but a plan-reviewer reads the plan *text* against the repo, +where stale line-anchors and already-merged-PR references at the pinned +base_sha are **real** defects. Verified: one plan's cited `REGISTRY.md:3506` +is actually at `:3594` at its base; another's base commit *is* its own +"PR-1." So the negatives were not clean, and the severity-thresholded FP gate +(any blocker on a "clean" plan = false positive) mislabeled true findings as +FPs. Precision was therefore re-measured as **hallucination rate** (true vs +false), which is the safety-critical axis and cleared. What remains +**unmeasured**: trivia-flooding on a *genuinely* clean plan — the corpus has +none. Closing that needs a small future run on constructed-clean negatives +(tracked follow-up), not a repeat of the 120-review matrix.
