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

`--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.
