This Skill helps translate natural language queries into ast-grep rules for structural code search. It enables searching code by its structure rather than text, allowing precise matches across large codebases.
Use the ast-grep skill to craft a rule that matches a specific code structure, then test it against a sample file to verify matches.

AST-based search finds code by its syntactic structure rather than literal text matches. This allows precise pattern matching across large codebases—for example, locating all async functions without error handling or identifying specific language constructs where grep or text search would miss context-dependent variations.
Translate natural language descriptions of code patterns into ast-grep rules using atomic operators (pattern, kind, regex), relational operators (inside, has, precedes, follows), and composite logic (all, any, not). Test rules against sample files to verify matches before applying them across your codebase.
Yes. AST-based rules work cross-language because they match code structure, not syntax. A single rule can find equivalent patterns in JavaScript, Python, Go, and other supported languages, provided each language's AST parser is available.
Text search matches character sequences and is vulnerable to whitespace, formatting, and naming variations. Structural search matches code by its AST shape, capturing semantically equivalent patterns regardless of how they're written, making it far more reliable for finding specific constructs.
No. This Skill translates natural language descriptions into ast-grep rule syntax. You describe what code pattern you're looking for in plain terms, and the rules are generated with support for pattern matching, conditionals, and relationships—no prior AST knowledge required.
AST rules detect patterns ranging from simple (specific function calls) to complex (functions meeting multiple structural conditions—for instance, async functions inside class methods with no try-catch blocks). Rules support negation, precedence, nesting, and composite logic to express precise structural requirements.
