Code Anti-patterns Analysis

Expert knowledge for systematic detection and analysis of anti-patterns, code smells, and quality issues across codebases using ast-grep and parallel agent delegation.

Analysis Philosophy

This skill emphasizes parallel delegation for comprehensive analysis. Rather than sequentially scanning for issues, launch multiple specialized agents to examine different categories simultaneously, then consolidate findings.
