Treesitter Skill

Parse code files or snippets using tree-sitter to extract symbols (functions, classes, methods).

Quick Start

# Extract symbols from a file
.agents/skills/treesitter/run.sh symbols /path/to/file.py --json

# Extract with full source code
.agents/skills/treesitter/run.sh symbols /path/to/file.py --content --json

# Scan a directory
.agents/skills/treesitter/run.sh scan /path/to/dir --json

# Parse a code snippet (writes to temp file)
.agents/skills/treesitter/run.sh parse --language python --code "def foo(): pass" --json

Commands

Command	Description
symbols <path>	Extract functions/classes from a file
scan <dir>	Walk directory, summarize symbols per file
parse --code "..." --language <lang>	Parse a code snippet

Options

Option	Description
--content, -c	Include full source code of symbols
--language	Override auto-detected language
--json	Output JSON format
--max-chunk-size	Max chars for content chunks

Auto-Install

This skill uses uvx to automatically install treesitter-tools from git. No pre-installation required.

Integration with Distill

The distill skill can use treesitter to properly extract and parameterize code blocks from documents, storing them with their language and structure.

Supported Languages

Python, JavaScript, TypeScript, Go, Rust, Java, C, C++, Ruby, and more. Language is auto-detected from file extension or can be specified with --language.
