SKILL.md

ast-grep uses tree-sitter to parse code into AST, enabling precise pattern matching. Rules are defined in YAML for linting, searching, and rewriting code.

Note: ast-grep scan command requires sgconfig.yml, while ast-grep run -p can be used standalone.

| Single node | $VAR | console.log($MSG) | | Multiple nodes | $$$ARGS | fn($$$ARGS) | | Same content | Use same name | $A == $A | | Non-capturing | $VAR | $FN($FN) |

Write AST-based code search and rewrite rules using ast-grep YAML. Create linting rules, code modernizations, and API migrations with auto-fix. Use when the user mentions ast-grep, tree-sitter patterns, code search rules, lint rules with YAML, AST matching, or code refactoring patterns. Source: heyvhuang/ship-faster.
