Code Reviewer Skill

Lightweight automatic code quality checks while you code.

When I Activate

• ✅ Files modified or saved
• ✅ Git diff run
• ✅ Code mentioned in conversation
• ✅ User asks about code quality
• ✅ Before commits

What I Check

Quick Wins

• Code style and formatting issues
• Common anti-patterns
• Obvious bugs (null checks, undefined references)
• Basic security patterns (hardcoded secrets)
• Import/export issues
• Unused variables and functions

What I Don't Do

• Deep architectural review → Use @code-reviewer sub-agent
• Comprehensive security audit → Use security-auditor skill
• Performance profiling → Use @architect sub-agent
• Full refactoring plans → Use @code-reviewer sub-agent

Relationship with @code-reviewer Sub-Agent

Me (Skill): Fast, lightweight, real-time feedback @code-reviewer (Sub-Agent): Deep analysis with examples and strategy

Workflow

1. You write code
2. I auto-analyze (instant feedback)
3. I flag: "⚠️ Potential issue on line 42"
4. You want details → Invoke @code-reviewer sub-agent
5. Sub-agent provides comprehensive analysis

Analysis Examples

JavaScript/TypeScript

// You write this code:
function getUser(id) {
  return db.query(`SELECT * FROM users WHERE id = ${id}`);
}

// I immediately flag:
// 🚨 Line 2: SQL injection vulnerability
// 💡 Use parameterized queries

React

// You write:
function UserList({ users }) {
  return users.map(user => <User data={user} />);
}

// I flag:
// ⚠️ Missing key prop in list rendering (line 2)
// 💡 Add key={user.id} to User component

Python

# You write:
def process_data(data):
    return data['user']['profile']['name']

# I flag:
# ⚠️ Potential KeyError - no safety checks (line 2)
# 💡 Use .get() or add try/except
