Review Pr

CDP PR Review

You are reviewing a pull request against the CDP (Community Data Platform) architecture standards and project conventions. Walk through each phase in order.

The review is backed by these living sources of truth — always pull current contents rather than relying on memory:

• .claude/rules/*.md — all project rules
• .claude/hooks/guard-protected-files.sh — the authoritative protected-files list
• CLAUDE.md — project conventions, patterns in transition

Phase 1: Input & Context Gathering

Parse arguments

The args string follows this format: <PR number> [extra instructions].

• First token is the PR number if numeric.
• Everything after it is extra instructions (e.g. "focus on backend", "check that previous comments were addressed").
• If no PR number is provided, use AskUserQuestion to ask for one.

Determine repository

gh repo view --json nameWithOwner --jq '.nameWithOwner'

Fetch PR metadata (parallel)

Run all of the following in a single turn:

# PR details
gh pr view <N> --json title,body,headRefName,baseRefName,author,files,additions,deletions,state,number

# Full diff
gh pr diff <N>

# Previous inline review comments
gh api repos/{owner}/{repo}/pulls/{N}/comments --paginate

# Previous review summaries
gh api repos/{owner}/{repo}/pulls/{N}/reviews --paginate

# Commit messages
gh api repos/{owner}/{repo}/pulls/{N}/commits --paginate --jq '.[].commit.message'

# Fetch both branches for merge-base check
git fetch origin <baseRefName> <headRefName>

If the diff is too large, save it to /tmp/pr-<N>.diff and read only changed .ts, .vue, .sql, .md files with Read.

Load all project rules (dynamic — do not hardcode)

Glob .claude/rules/*.md and read every rule file. New rules added in the future must be picked up automatically; never maintain a hand-kept list here. At time of writing this includes:

• commit-workflow.md — PR title format, branch naming, JIRA key, signing
• adr-format.md — ADR template enforcement (scoped to docs/adr/)
• skill-guidance.md — skill routing table

Load the protected-files hook

Read .claude/hooks/guard-protected-files.sh. Parse its case statements and if conditions to build the authoritative protected-files list. Never maintain it by hand — parse the hook so it stays in sync.

Phase 2: Launch Code Enforcer (background)

Spawn a background Agent subagent (code-standards-enforcer) with run_in_background: true. Proceed to Phase 3 immediately while it runs in parallel.

Prompt for the agent:

You are a code-standards enforcer for the CDP (Community Data Platform) codebase. Your job is to read every changed file on the PR branch and flag violations of project conventions.

Branch: origin/<headRefName> Changed files: (include the full list from Phase 1)

For each file, read it with git show origin/<headRefName>:<path> and check against:

1. .claude/rules/*.md — glob and read all rule files
2. CLAUDE.md — project conventions and patterns-in-transition
3. Domain checklists:
   • Backend files (backend/**) → .claude/skills/review-pr/references/backend-checklist.md
   • Frontend files (frontend/**) → .claude/skills/review-pr/references/frontend-checklist.md
   • Service files (services/apps/**, services/libs/**) → .claude/skills/review-pr/references/services-checklist.md
   • SQL / migrations (backend/src/database/migrations/**, any .sql) → .claude/skills/review-pr/references/sql-checklist.md

Also read .claude/hooks/guard-protected-files.sh and parse its case/if patterns. For every changed file matching a protected pattern, emit a NIT finding with the hook's warning reason.

Severity calibration:

• CRITICAL — runtime bugs, security issues, new Sequelize usage in non-legacy files, new public endpoint without validateOrThrow/Zod schema, multi-tenant logic beyond DEFAULT_TENANT_ID, secrets hardcoded
• SHOULD_FIX — documented style/structure violations (new class-based service/repo, any types in new code, DAL function added without checking for existing equivalents, missing license headers)
• NIT — minor improvements, naming, protected-file awareness

Return findings as JSON: [{ "file": "...", "line": N, "severity": "CRITICAL|SHOULD_FIX|NIT", "rule": "<source>:<section>", "message": "...", "suggestion": "..." }]

If you cannot quote the rule from a loaded rule file, checklist, or CLAUDE.md, drop the finding. Hallucinated rules are worse than missed ones.

Phase 3: Verify Previous Review Comments

Check whether previously raised review comments were actually addressed in code. Do NOT trust "resolved" status — read the actual code.

1. Gather all inline comments and review bodies from Phase 1.
2. Skip trivial comments: nits, "+1", bot auto-comments, purely informational remarks.
3. For every CRITICAL or SHOULD FIX comment:
   1. Read the file on the PR branch: git show origin/<headRefName>:<file>
   2. Compare current code against what the comment requested.
   3. Classify: FIXED / NOT FIXED / PARTIALLY FIXED / N/A
4. Build a markdown table:

| #   | Comment Summary                    | File                                     | Status    | Evidence                              |
| --- | ---------------------------------- | ---------------------------------------- | --------- | ------------------------------------- |
| 1   | Use queryExecutor not Sequelize    | services/libs/data-access-layer/foo.ts   | FIXED     | Line 12 now uses queryExecutor        |
| 2   | Missing validateOrThrow on endpoint | backend/src/api/members.ts              | NOT FIXED | Route still has no Zod schema         |

If no previous review comments, note "No previous review comments found" and move on.

Phase 4: PR Metadata Validation

Validates PR metadata against commit-workflow.md.

Checks

1. PR title format — must follow Conventional Commits format: type: description (CM-XXX). The JIRA key goes in parentheses at the end. CI validates the presence of any JIRA key pattern (/\b[A-Z]+-\d+\b/).

   • Valid types: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert

2. JIRA key present — PR title must contain a JIRA key (checked by CI at .github/workflows/pr-title-jira-key-lint.yml). Extract with grep -oE '[A-Z]+-[0-9]+'. If none, flag CRITICAL.

3. Branch name format — should match type/CM-<number> (e.g. feat/CM-1164-github-discussions). Flag as NIT if non-conforming but otherwise well-formed.

4. Branch rebased on main:

   git merge-base --is-ancestor origin/main origin/<headRefName>
   

   If non-zero exit code, flag SHOULD FIX: branch needs a rebase.

5. PR size — if additions > 1000, note per commit-workflow.md's 1000-line target.

6. Commit signing — at least one commit should have Signed-off-by: trailer (DCO).

Build a findings table:

| Check           | Status | Detail                                          |
| --------------- | ------ | ----------------------------------------------- |
| PR title format | PASS   | `feat: add github discussions source (CM-1164)` |
| JIRA key        | PASS   | Found CM-1164                                   |
| Branch name     | PASS   | `feat/CM-1164-github-discussions`               |
| Branch rebased  | PASS   | origin/main is an ancestor                      |
| PR size         | PASS   | 342 additions                                   |
| DCO sign-off    | PASS   | All commits signed                              |

Phase 5: Compile Context

Wait for the Phase 2 enforcer Agent to complete. Then compile all findings.

Apply false-positive filter

Before surfacing any finding, drop it if:

• The rule field cannot be matched by string search in the loaded rule files, checklists, or CLAUDE.md
• It relates to patterns from other codebases (Angular, Nuxt, Go-specific rules, etc.)
• It flags legacy Sequelize/class usage in files that are clearly already legacy (backend/src/database/repositories/, backend/src/services/) — only flag NEW usage

Assemble the context block

1. Previous comment verification — Phase 3 table (or "No previous review comments found")
2. PR metadata validation — Phase 4 table
3. Protected files touched — list any matching .claude/hooks/guard-protected-files.sh, with the hook's warning reason
4. Code enforcer findings — filtered JSON results from Phase 2
5. Domain checklists applied — note which checklists were used
6. Extra user instructions — any additional instructions from the args

Phase 6: Present Draft Review for Approval (NEVER auto-post)

You MUST NOT post inline comments, submit a review, or request changes without the user's explicit approval. Always present the draft first and wait for a clear go-ahead. This applies every time, with no exceptions.

Step 1 — Show the draft

Print the compiled context as a draft review summary:

1. PR summary — number, title, author, size, branch
2. Phase 3 table — previous comments and whether they were addressed
3. Phase 4 table — PR metadata validation
4. Protected files touched — list with hook reasons
5. Proposed inline comments — one block per finding: file:line, severity, rule citation, message, suggested fix. Number them so the user can reference individual items.
6. Proposed review body — summary text for the top of the review
7. Proposed review verdict — COMMENT / APPROVE / REQUEST_CHANGES, with reasoning

Step 2 — Ask for approval

Use AskUserQuestion with options:

• "Post all comments as drafted"
• "Post with changes — I'll tell you which comments to drop or edit"
• "Don't post — just keep the summary here"

Do NOT proceed until the user explicitly picks an option. Treat silence or ambiguous replies as "don't post".

Step 3 — Only after approval: invoke /review

Once the user approves (with or without edits), apply their edits and use the Skill tool to invoke review with the PR number and compiled context:

<PR number> -- <compiled context from Phase 5, with user's edits applied>

If the user said "don't post", stop here — do not invoke /review or any PR-mutating gh command.

Additional Rules

PR size check

If additions > 1000, include in the review body:

Note: This PR has {additions} additions, which exceeds the recommended 1000-line target per commit-workflow.md. Consider splitting into smaller, independently reviewable PRs.

New contributor awareness

gh pr list --author <author> --state merged --limit 5 --json number | jq 'length'

If the author has fewer than 5 merged PRs to this repo, be more educational in inline comments — explain the why behind each rule, not just the what.

Extra instructions

If the user passed extra instructions after the PR number, prioritize those areas but still execute the full review pipeline.
