ast-grep Skill

ast-grep is a structural code search and rewriting tool. Use it when you need to find or modify code based on its AST structure rather than text patterns.

When to Use ast-grep

Use ast-grep when:

• Searching for code patterns (function calls, imports, specific constructs)
• Refactoring code systematically
• Finding deprecated patterns or anti-patterns
• The pattern involves code structure, not just text

Use grep/ripgrep when:

• Searching for literal strings, comments, or documentation
• Simple text matching is sufficient
