ast-grep

Structural code search using Abstract Syntax Tree patterns for precise codebase queries. This skill helps translate natural language queries into ast-grep rules for structural code search. ast-grep uses Abstract Syntax Tree (AST) patterns to match code based on its structure rather than just text, enabling powerful and precise code search across large codebases. Use this skill when users: Follow this process to help users write effective ast-grep rules: Clearly understand what the user wants to find. Ask clarifying questions if needed: Write a simple code snippet that represents what the user wants to match. Save this to a temporary file for testing. Example: If searching for "async functions that use await", create a test file: Translate the pattern into an ast-grep rule. Start simple and add complexity as needed. Key principles: Example rule file (test_rule.yml): See references/rule_reference.md for comprehensive rule documentation.
