Ln 653 Runtime Performance Auditor

levnikolaevich/claude-code-skills
371 installs533 stars
Summary

This auditor catches runtime performance killers in async codebases: blocking IO calls inside async functions, time.sleep instead of asyncio.sleep, string concatenation in loops, and unnecessary list allocations where generators would work. It scans your code with two-layer detection (candidate then verification), assigns severity based on whether violations hit hot paths like API handlers, and outputs a scored markdown report with specific file locations and effort estimates. Built for the L3 audit worker framework, so it integrates with hex-graph MCP tools when available but falls back to grep and bash if needed. The scoring penalizes HIGH findings harder than MEDIUM or LOW, giving you a compliance score out of 10 for the runtime performance category.
