# Tree-sitter Patterns Skill Universal patterns for working with tree-sitter in any project. Covers AST parsing, query patterns, visitors, and language plugin development. ## Design Principle This skill is **framework-generic**. It provides universal tree-sitter patterns: - NOT tailored to Code-Index-MCP, treesitter-chunker, or any specific project - Covers common patterns applicable across all tree-sitter projects - Project-specific queries go in project-specific skills ## Variables | Variable | Default | Description | |----------|---------|-------------| | TREE_SITTER_DIR | tree_sitter | Directory for language parsers | | QUERY_DIR | queries | Directory for .scm query files | | LANGUAGES | auto | Auto-detect or list of languages | ## Instructions **MANDATORY** - Follow the Workflow steps below in order. 1. Identify languages to parse 2. Install appropriate language parsers 3. Write queries for extraction needs 4. Handle edge cases and errors ## Red Flags - STOP and Reconsider If you're about to: - Parse without error handling (syntax errors are common) - Assume all files parse successfully - Write queries without testing on sample code - Ignore performance for large files **STOP** -> Add error handling -> Test on edge cases -> Then proceed ## Cookbook ### Language Plugin Development - IF: Creating a new language parser - THEN: Read and execute `./cookbook/language-plugin.md` ### AST Visitor Patterns - IF: Walking the AST to extract information - THEN: Read and
