Which programming languages are supported?

The skill provides specialized commands and optimization patterns for Node.js, TypeScript, Go, and SQL, but the general algorithmic workflow can be applied to any language.

How does it ensure optimizations don't break my code?

The workflow mandates a strict verification step where all existing tests must pass and output correctness is validated against the baseline before an optimization is considered complete.

How does the Performance Optimizer identify bottlenecks?

It uses language-specific profiling tools like Node.js CPU profiles and Go pprof, combined with targeted code search, to locate 'hotspots' where execution time or memory usage is highest.

Does this skill support database optimization?

Yes, it includes specific workflows for identifying N+1 queries, adding missing indexes, and refactoring inefficient SQL selection patterns into batch operations.

Analytics & Monitoring

Analyzes code bottlenecks and implements systematic performance optimizations using data-driven profiling and optimization workflows.

The Performance Optimizer skill provides a structured framework for identifying, measuring, and resolving execution delays and resource inefficiencies in software projects. It guides Claude through a rigorous six-step process: establishing baseline metrics, profiling hotspots in Node.js or Go, identifying common antipatterns like N+1 queries, applying targeted algorithmic or I/O improvements, and verifying results with regression testing. This ensures that speed enhancements are quantifiable and do not compromise the correctness of the application.
