Review PR

Overview

Perform a read-only review and produce both human and machine-readable outputs.

Inputs

• Ask for PR number or URL.
• If missing, always ask.

Safety

• Never push, merge, or modify code intended to keep.
• Work only in .worktrees/pr-<PR>.
• Wrapper commands are cwd-agnostic; you can run them from repo root or inside the PR worktree.

Execution Contract

1. Run wrapper setup:

scripts/pr-review <PR>

1. Use explicit branch mode switches:

• Main baseline mode: scripts/pr review-checkout-main <PR>
• PR-head mode: scripts/pr review-checkout-pr <PR>

1. Before writing review outputs, run branch guard:

scripts/pr review-guard <PR>

1. Write both outputs:

• .local/review.md with sections A through J.
• .local/review.json with structured findings.

1. Validate artifacts semantically:

scripts/pr review-validate-artifacts <PR>

Steps

1. Setup and metadata

scripts/pr-review <PR>
ls -la .local/pr-meta.json .local/pr-meta.env .local/review-context.env .local/review-mode.env

1. Existing implementation check on main

scripts/pr review-checkout-main <PR>
rg -n "<keyword>" -S src extensions apps || true
git log --oneline --all --grep "<keyword>" | head -20

1. Claim PR

gh_user=$(gh api user --jq .login)
gh pr edit <PR> --add-assignee "$gh_user" || echo "Could not assign reviewer, continuing"

1. Read PR description and diff

scripts/pr review-checkout-pr <PR>
gh pr diff <PR>

source .local/review-context.env
git diff --stat "$MERGE_BASE"..pr-<PR>
git diff "$MERGE_BASE"..pr-<PR>

1. Optional local tests

Use the wrapper for target validation and executed-test verification:

scripts/pr review-tests <PR> <test-file> [<test-file> ...]

1. Initialize review artifact templates

scripts/pr review-artifacts-init <PR>

1. Produce review outputs

• Fill .local/review.md sections A through J.
• Fill .local/review.json.

Minimum JSON shape:

{
  "recommendation": "READY FOR /prepare-pr",
  "findings": [
    {
      "id": "F1",
      "severity": "IMPORTANT",
      "title": "...",
      "area": "path/or/component",
      "fix": "Actionable fix"
    }
  ],
  "tests": {
    "ran": [],
    "gaps": [],
    "result": "pass"
  },
  "docs": "up_to_date|missing|not_applicable",
  "changelog": "required"
}

1. Guard + validate before final output

scripts/pr review-guard <PR>
scripts/pr review-validate-artifacts <PR>

Guardrails

• Keep review read-only.
• Do not delete worktree.
• Use merge-base scoped diff for local context to avoid stale branch drift.
