Review Plan Implementation

Goal

Given a .plan.md file, validate the implementation by following the plan's ## Reviewer Handoff instructions and reporting whether code changes align with the plan.

When to use

Use this skill when a user asks to review, verify, or audit work completed from a plan file in .cursor/plans/*.plan.md.

Minimal workflow

1. Load and validate the plan file

   • Read the provided .plan.md path.
   • Confirm YAML frontmatter exists and todos are present.
   • Confirm a ## Reviewer Handoff section exists.
   • If ## Reviewer Handoff is missing, stop and report that the plan cannot be reviewed with this skill until that section is added.

2. Extract handoff instructions

   • Parse the ## Reviewer Handoff section and identify:
     • Implementation summary claims
     • File-level changelog entries
     • UI manual verification checklist

3. Review plan alignment (code review mindset)

   • Compare completed todos in frontmatter to the claimed implementation in ## Reviewer Handoff.
   • Inspect changed files and verify claims are accurate.
   • Prioritize findings:
     • Bugs
     • Behavioral regressions
     • Missing or incorrect implementation versus the plan
     • Missing tests or verification gaps
   • If no issues are found, explicitly state that.

4. Execute or delegate UI verification

   • Use the UI checklist from ## Reviewer Handoff as the source of truth.
   • Assume the tester has no codebase context.
   • Ensure each UI step references a route/page and specific on-page area (section/panel/table).
   • If a step is ambiguous (for example component names only), rewrite it into actionable user-facing steps and call out that rewrite.

5. Report format

   • Present findings first, ordered by severity, with file references where applicable.
   • Then provide:
     • Open questions/assumptions
     • Plan alignment verdict (aligned, partially aligned, not aligned)
     • UI verification status and any blockers

Output template

Use this structure:

Review target: `<plan filepath>`

Findings:
1. [Severity] <title> — `<file path:line>`
1. [Severity] <title> — `<file path:line>`

Open questions / assumptions:
1. <question or assumption>

Plan alignment verdict: <aligned | partially aligned | not aligned>

UI verification:
1. <what was verified>
1. <what remains or is blocked>

Notes

• Do not modify the plan status while reviewing unless the user explicitly asks for updates.
• Treat ## Reviewer Handoff as the authoritative review scope unless the user expands scope.
• If the user asks for a strict sign-off decision, provide a clear yes/no with rationale.
