Performance Optimizer

Trigger

Use when:

• User says /optimize
• User reports slowness or high resource usage
• User asks for performance improvements

Do NOT use when:

• User asks for readability improvements (use /simplify)
• User asks for security audit (use /security-review)

Steps

Step 1: Profile (if applicable)

If user provides runtime data or if profiling is straightforward:

# Examples by platform/language
/usr/bin/time -v ./script.sh        # Linux
python -m cProfile -s cumtime script.py
node --prof script.js

If no runtime data, skip to Step 2 with static analysis.

Step 2: Identify Bottlenecks

Analyze for:

• Algorithmic complexity (O(n²) → O(n log n))
• Synchronous I/O in loops
• N+1 query patterns
• Missing database indexes
• Unbounded memory growth
• Repeated expensive computations without caching

Step 3: Generate Report

Use the output format below.

Output Format

## Performance Review

### Bottlenecks Found

#### 🔴 [Severity] [Category]
**File**: `path:line`
**Issue**: [Description]
**Impact**: [Quantify if possible]
**Fix**: [Recommendation]

#### 🟠 ...

### Recommendations (Priority Order)
1. [Highest impact fix]
2. [Next fix]

Constraints

• Do NOT optimize without profiling data unless obvious algorithmic issue
• Focus on the 20% causing 80% of slowdown (Pareto)
• Verify each suggestion is measurable
• Do NOT auto-apply changes
