Optimize Skill

Performance analysis and optimization.

When to Activate

This skill is relevant when:

• Performance improvements needed
• Bottlenecks identified
• Load time too slow
• Bundle size too large
• Query performance poor
• Resource usage high

Core Principles

Milliseconds Matter

• Every millisecond saved is a win
• Users notice speed differences
• Performance impacts UX
• Optimize critical paths
• Measure everything

Efficiency

• O(n) is acceptable
• O(n^2) is a crime
• Choose right algorithms
• Minimize iterations
• Cache strategically

Resource Usage

• Minimize memory footprint
• Reduce CPU cycles
• Optimize network calls
• Lazy load resources
• Bundle size matters

Measure First

• Baseline before optimizing
• Benchmark current state
• Identify bottlenecks
• Verify improvements
• Compare before/after

Quick Checks

For performance optimization, verify:

• Application is functional
• Baseline metrics captured
• Load time measured
• Execution time measured
• Bundle size measured
• Bottlenecks identified
• Database queries analyzed
• N+1 queries found
• Unnecessary re-renders found
• Large assets identified
• Optimizations applied
• Benchmarks re-run
• Improvements verified
• Before/after comparison documented
• No regressions introduced

Optimization Targets

Database

• Add missing indexes
• Optimize query structure
• Reduce query count
• Implement caching
• Avoid N+1 queries
• Use connection pooling

Frontend

• Implement memoization
• Add lazy loading
• Optimize images
• Reduce re-renders
• Code splitting
• Virtual scrolling

Backend

• Optimize algorithms
• Implement caching
• Reduce API calls
• Batch operations
• Async processing
• Resource pooling

Bundle

• Tree-shake unused code
• Split code chunks
• Lazy load routes
• Optimize dependencies
• Remove duplicates
• Compress assets

Performance Metrics

Load Time

• Initial page load
• Time to interactive
• First contentful paint
• Largest contentful paint

Execution Time

• API response time
• Query execution time
• Function execution time
• Render time

Resource Usage

• Memory consumption
• CPU utilization
• Network bandwidth
• Bundle size
• Asset sizes

Benchmarking

Baseline

Measure current performance state

Bottlenecks

Identify slowest operations

Optimizations

Apply targeted improvements

Verification

Confirm improvements with metrics
