SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Translate natural language queries into ast-grep rules to enable structural code search across large codebases.

Core Features & Use Cases

  • Convert NL questions into ast-grep patterns for code search with structural accuracy.
  • Provide workflow steps, example rules, and testing guidance in the references to locate language constructs.
  • Use for rapid discovery, refactoring previews, and targeted code audits.

Quick Start

Ask the AI to generate an ast-grep rule for your query and test it on a sample project.

Frequently Asked Questions about ast-grep

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I search for specific code patterns across a large codebase using abstract syntax tree matching?▼

Structural code search using ast-grep pattern matching matches code constructs based on syntax structure rather than plain text. It uses an abstract syntax tree DSL with metavariables to locate language constructs with high precision across large codebases.

Can I convert natural language questions into ast-grep rules for code analysis?▼

Yes, you can convert natural language questions into ast-grep rules for code analysis. The Skill translates NL queries into ast-grep patterns using the DSL with metavariables and stopBy semantics, enabling structural code search with high precision.

What's the best way to generate ast-grep rules for locating specific language constructs?▼

The best way to generate ast-grep rules for locating language constructs is to ask the AI to translate your natural language query into an ast-grep pattern. You then test the generated rule, which uses metavariables and stopBy semantics, on a sample project to verify accuracy.

Does structural code search with ast-grep support refactoring previews and code audits?▼

Yes, structural code search with ast-grep supports refactoring previews and targeted code audits. By translating NL queries into ast-grep rules, you can apply pattern matching across codebases to locate specific language constructs for rapid discovery and structural code reviews.

Do I need to learn the ast-grep DSL and metavariables to use natural language to rule translation?▼

You do not need to manually write the ast-grep DSL to use natural language to rule translation, but understanding metavariables and stopBy semantics helps. The Skill generates the ast-grep rule from your NL query, while references provide example rules and testing guidance.
