Code Reviewer (Meta-Skill)

Purpose

Automatically routes code review requests to the most appropriate reviewer based on context and user preferences. This meta-skill provides a unified interface for accessing multiple code review implementations.

Available Reviewers

code-review-claude - Fast, native code review (< 30 seconds)
Best for: Quick validation checks during development
Strength: Speed and immediate feedback
code-review-gemini - Deep, external perspective review
Best for: Thorough reviews with alternative AI viewpoint
Strength: Different perspective, catches different issues

Trigger Phrases

When the user mentions any of these, activate this skill:
- "review"
- "code review"
- "review my code"
- "review the code"
- "check the code"
- "review changes"
- "review staged files"

Decision Logic

Step 1: Check User Preferences

Read from ~/.claude/CLAUDE.md section 9 (Notice) → Skill Preferences → Code Review:
- Default reviewer preference
- Fallback options
- Any context-specific overrides

Step 2: Analyze Context

Examine the current situation:

Factor	How to Check	Impact
File count	`git diff --cached --name-only \\| wc -l`	Many files → prefer thorough review
Line count	`git diff --cached --shortstat`	Few lines → quick review acceptable
User keywords	Check for "quick", "fast", "thorough", "checklist"	Override preferences
Complexity	File types, languages involved	Complex → prefer thorough review

Step 3: Apply Routing Rules

Execute routing logic in priority order:

Priority	Condition	Action	Reason
1	User says "quick" or "fast"	→ `code-review-claude`	Speed required
2	User says "thorough" or "deep" or "gemini"	→ `code-review-gemini`	Depth required
3	CLAUDE.md preference set	→ Use preferred reviewer	Respect user default
4	< 50 lines changed AND < 3 files	→ `code-review-claude`	Small change, quick check
5	Default (no preference set)	→ `code-review-gemini`	Best balance

Step 4: Execute and Report

Inform user: "Using {skill_name} for this review..."
Invoke skill: Use the Skill tool to call the selected reviewer
Pass through results: Return the review output to the user

Implementation

When this skill is triggered:

1. Parse user request for keywords (quick, thorough, checklist)
2. Check for staged changes: git diff --cached --shortstat
3. Read CLAUDE.md preferences (if they exist)
4. Apply routing rules (priority order above)
5. Report decision: "Using code-review-gemini for this review..."
6. Execute: Skill tool with selected reviewer
7. Return results to user

Examples

Example 1: Default Review (with preference)

User: "Review my code"
Assistant: [Checks CLAUDE.md, sees gemini is preferred]
Assistant: "Using code-review-gemini for this review..."
Assistant: [Calls Skill tool with skill="code-review-gemini"]

Example 2: Quick Review Override

User: "Quick review of my changes"
Assistant: [Detects "quick" keyword]
Assistant: "Using code-review-claude for fast feedback..."
Assistant: [Calls Skill tool with skill="code-review-claude"]

Example 3: Small Change Auto-Detection

User: "Review this"
Assistant: [Checks: 15 lines changed in 1 file, no preference set]
Assistant: "Small change detected. Using code-review-claude for quick check..."
Assistant: [Calls Skill tool with skill="code-review-claude"]

Example 4: Large Change Auto-Detection

User: "Review changes"
Assistant: [Checks: 250 lines changed across 8 files]
Assistant: "Substantial changes detected. Using code-review-gemini for thorough review..."
Assistant: [Calls Skill tool with skill="code-review-gemini"]

Configuration

Users can set preferences in ~/.claude/CLAUDE.md:

## 9. Notice

### Skill Preferences

#### Code Review
- **Default reviewer**: code-review-gemini
- **Quick review fallback**: code-review-claude
- **Rationale**: Gemini provides external perspective, Claude for speed

Direct Access

Users can still bypass this meta-skill and call specific reviewers directly:

/skill code-review-gemini     # Force gemini
/skill code-review-claude     # Force claude
/skill code-review-checklist  # Force checklist

This preserves user control while providing intelligent defaults.

Design Principles

Single Entry Point - Users remember one command: "review my code"
Transparent Decision - Always tell user which reviewer is being used
Respect Preferences - Honor user's CLAUDE.md settings
Context-Aware - Consider file count, line count, complexity
Override-Friendly - Keywords (quick, thorough) override defaults
Direct Access Preserved - Users can still call specific skills

Implementation Notes

This meta-skill does NOT contain review logic
It only performs routing and delegation
All actual review work is done by specialized skills
Decision logic is simple and rule-based (no complex AI needed)
Routing rules are listed in priority order for clarity
