Does this skill automatically modify my code?

No, this skill is designed for analysis only. It identifies issues and suggests optimizations but does not make any changes to your source files.

Does it work with any programming language?

The skill performs a technology discovery phase to adapt its patterns to your specific stack, covering major backend, frontend, and database technologies.

Can I scan specific commits or pull requests?

Yes, you can target specific PR numbers, commit SHAs, or specific scopes like 'database' or 'frontend' to focus the analysis.

How does it handle false positives?

It follows strict anti-hallucination guidelines, requiring verified pattern matches and context analysis (hot path vs. cold path) before reporting an issue.

分析と監視

Conducts deep performance audits across database queries, algorithms, frontend assets, and system resources to identify bottlenecks.

The Performance Reviewer skill empowers Claude to act as a dedicated performance engineer, scanning codebases or pull requests to uncover hidden inefficiencies. By deploying four specialized parallel agents, it systematically analyzes database query patterns, algorithmic complexity, frontend rendering issues, and potential resource leaks. Each audit produces a comprehensive, prioritized report with severity rankings and actionable optimization strategies, making it an essential tool for pre-deployment checks and technical debt reduction without the risk of unintended code modifications.

主な機能

01Identifies N+1 database queries and missing indexes across SQL and NoSQL stacks.

02Detects frontend performance issues including bundle bloat and rendering thrashing.

03Performs Big O analysis to detect algorithmic complexity and computational bottlenecks.

04Uncovers resource leaks such as unclosed file handles and memory mismanagement.

052 GitHub stars

06Generates detailed Markdown reports with prioritized findings and optimization examples.

ユースケース

01Identifying the root cause of latent database latency in legacy backend services.

02Evaluating frontend code for Core Web Vitals compliance and rendering efficiency.

03Auditing Pull Requests for performance regressions before they reach production.
