    Sample input

    My UserProfile component is sluggish. p95 latency is 840ms, and I need it under 200ms. Help me find the bottleneck and fix it using the 5-phase framework.

    Sample output

    Performance Optimization Report Baseline: p95 latency 840ms Target: <200ms Bottleneck: N+1 query in UserProfile component Root Cause: Nested map() calling db.findUnique() Optimization: Implemented batch loading with DataLoader Verified Result: p95 latency 142ms (83% improvement)

    About This Skill

    Solve Performance Issues at the Root

    Stop guessing which lines of code are slow. This skill provides a systematic, 5-phase engineering framework for diagnosing bottlenecks and implementing verified optimizations. It moves your agent beyond superficial suggestions into data-driven performance engineering.

    What it does

    The skill guides your agent through a rigorous process: establishing baselines, selecting the right profiling tools (CPU, RAM, DB), conducting root cause analysis, and implementing targeted fixes. It emphasizes the 80/20 rule to ensure you focus on high-impact wins rather than micro-optimizations in cold code paths.

    Supported Workflows & Tools

    • Profiling: Integrates with language-specific profilers and database explain plans.
    • Regression Protection: Generates performance tests and monitoring alerts to ensure your speed wins don't disappear in the next PR.
    • Framework Agnostic: Works across Node.js, Python, SQL, Prisma, and more.

    Why developers use this

    Unlike a standard prompt, this skill enforces "hard stops." Your agent won't be allowed to change a single line of code until it has documented a measurable baseline and defined success criteria. This prevents "optimization churn" and ensures every change is a documented improvement.

    Use Cases

    • Identify and fix P95 latency spikes in production APIs
    • Eliminate N+1 query problems and inefficient database access patterns
    • Generate performance regression tests to lock in speed improvements
    • Conduct systematic memory leak analysis and resolution
    • Optimize resource-heavy background jobs for better throughput
