# Tree-sitter Skill ## Overview Expert skill for creating tree-sitter grammars for incremental parsing and syntax highlighting. ## Capabilities - Write tree-sitter grammar.js files - Handle tree-sitter external scanners - Design queries for syntax highlighting - Implement incremental parsing support - Handle tree-sitter error recovery - Generate bindings for various languages - Integrate with editors (VS Code, Neovim, Helix) - Test grammars with corpus files ## Target Processes - language-grammar-design.js - lexer-implementation.js - parser-development.js - lsp-server-implementation.js ## Dependencies - tree-sitter CLI - tree-sitter crates/npm packages ## Usage Guidelines 1. **Grammar.js**: Follow tree-sitter grammar.js conventions 2. **External Scanners**: Use external scanners for context-sensitive lexing 3. **Queries**: Write highlight.scm and other query files for editor integration 4. **Testing**: Build comprehensive corpus test files 5. **Error Recovery**: Design grammar with error recovery in mind ## Output Schema ```json { "type": "object", "properties": { "grammarName": { "type": "string" }, "nodeTypes": { "type": "array", "items": { "type": "string" } }, "queries": { "type": "array", "items": { "type": "string", "enum": ["highlights", "injections", "locals", "tags", "folds"] } }, "bindings": { "type": "array", "items": { "type": "string" } }, "generatedFiles": {...
