Which frameworks does it support for bundle analysis?

The skill includes native detection and analysis for Webpack, Vite, and Next.js build configurations.

Can it detect inefficient code patterns automatically?

Yes, it performs algorithmic analysis to identify O(n^2) loops, nested collections, and unindexed database queries.

Does it work with non-JavaScript languages?

Absolutely. It features built-in support for benchmarking and profiling Rust (cargo), Go (go test), and Python (pytest) projects.

How are performance findings reported?

It generates a structured GitHub issue containing a scan metadata table, severity-ranked findings, and specific recommended actions.

分析与监控

Analyzes codebase performance metrics, identifies bottlenecks, and automates reporting through structured GitHub issues.

The Performance Analysis skill provides a comprehensive auditing suite for Claude Code, enabling it to detect bundle size regressions, algorithmic inefficiencies, and unoptimized database queries. It integrates seamlessly with popular build tools like Vite and Next.js, executes language-specific benchmarks for Rust, Go, and Python, and performs deep heuristic scans to find O(n^2) patterns or blocking synchronous code. By automating the discovery and classification of performance-sensitive areas, it helps developers maintain high-speed applications and documents findings directly into project management workflows.
