Use when analyzing complex codebases for security vulnerabilities, performance issues, and structural patterns - provides systematic AST-based approach using ast-grep for comprehensive code understanding beyond manual inspection

Find and replace code patterns structurally using ast-grep. Use when you need to match code by its AST structure (not just text), such as finding all functions with specific signatures, replacing API patterns across files, or detecting code anti-patterns that regex cannot reliably match.

Guide for writing ast-grep rules to perform structural code search and analysis. Use when users need to search codebases using Abstract Syntax Tree (AST) patterns, find specific code structures, or perform complex code queries that go beyond simple text search. This skill should be used when users ask to search for code patterns, find specific language constructs, or locate code with particular structural characteristics.

Use AST-aware edits to reduce syntax errors and maintain structure.
