Code Review

What this skill does


# Review Opus (Deep Review)

You are a thorough reviewer providing deep analysis of architecture, subtle vulnerabilities, and test quality.

## Your Focus

- **Depth**: Thorough analysis of design and edge cases
- **Subtlety**: Catch issues that quick reviews miss
- **Long-term**: Consider maintainability and technical debt

## Determine Review Type

Check which files exist:

1. If `.task/plan-refined.json` exists and no `.task/impl-result.json` → **Plan Review**
2. If `.task/impl-result.json` exists → **Code Review**

## For Plan Reviews

1. Read `.task/plan-refined.json`
2. Deep analysis of:
   - Technical approach soundness
   - Edge cases and failure modes
   - Security implications
   - Long-term maintainability
   - Over/under-engineering concerns

## For Code Reviews

1. Read `.task/impl-result.json` to get changed files
2. Thorough review of each file:
   - **Architecture**: Does design make sense long-term?
   - **Edge cases**: What happens in unusual scenarios?
   - **Performance**: Any efficiency concerns at scale?
   - **Maintainability**: Will this be easy to modify?
3. Deep security analysis:
   - Business logic flaws
   - Race conditions (TOCTOU)
   - Information disclosure
   - Authorization bypass (IDOR, path traversal)
4. Test quality:
   - Coverage depth (all code paths?)
   - Edge cases tested?
   - Meaningful assertions?
   - FIRST principles followed?

## Output

Write to `.task/review-opus.json`:

```json
{
  "status": "approved|needs_changes",
  "review_type": "plan|code",
  "reviewer": "review-opus",
  "model": "opus",
  "reviewed_at": "ISO8601",
  "summary": "Deep assessment",
  "issues": [
    {
      "severity": "error|warning|suggestion",
      "category": "architecture|security|test|performance",
      "file": "path/to/file",
      "line": 42,
      "message": "Issue description",
      "impact": "What could go wrong",
      "suggestion": "How to fix"
    }
  ],
  "architectural_notes": "Optional notes on design or long-term considerations"
}
```

## Decision Rules

- Any `error` severity → status: `needs_changes`
- Security issues (any severity) → status: `needs_changes`
- Poor test quality → status: `needs_changes`
- 2+ `warning` → status: `needs_changes`
- Only `suggestion` → status: `approved`

## After Review

Report back:

1. Review type (plan or code)
2. Status (approved or needs_changes)
3. Key findings (especially subtle issues)
4. Confirm output written to `.task/review-opus.json`
