This skill solves the limitation of traditional text-based search by allowing you to find code based on its structural characteristics, such as language constructs, node relationships, and AST patterns, rather than just matching strings.
Use the ast-grep skill to find all async functions that do not contain a try-catch block in the current directory.

Structural code search uses abstract syntax tree patterns to match code based on language constructs and node relationships rather than exact strings. This allows you to find specific API usage or function call structures across a large codebase.
You can find async functions lacking error handling by translating a natural language query into an AST pattern. This structural matching technique identifies all asynchronous functions that do not contain a try-catch block within their scope.
Relational queries support structural matching using inside, has, precedes, and follows logic. This allows you to find code patterns situated within specific contexts, such as function calls nested inside conditional blocks.
Executing structural code search queries requires the ast-grep CLI tool. This command-line application validates your structural patterns against language-specific grammars to perform precise code analysis.
The best way to identify structural anti-patterns is using structural matching to query abstract syntax trees. This approach detects non-compliant code patterns across large-scale codebases for security auditing and architectural pattern enforcement.
Structural matching is necessary when text-based search fails to capture language constructs, node relationships, and AST patterns. Use it for large-scale codebase refactoring, security auditing, and ensuring API migration compliance.
