tree-sitting
AST-powered code navigation via tree-sitter.
Going through the checklist
What it does
AST-powered code navigation using tree-sitter. Each invocation auto-scans the codebase (~700ms for 250 files), then runs queries at sub-millisecond speed.
Use when exploring unfamiliar repos, navigating code, or needing fast symbol lookup
You don’t need to name it. Ask for the job in your own words — your AI loads the skill when the request matches.
What it can touch
Includes 11 scripts
Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.
How we know
Found in the skill’s folder: scripts/build_grammars.py, scripts/engine.py, scripts/server.py, scripts/treesit.py…; binary files: parsers/libtree_sitter_c.dylib, parsers/libtree_sitter_c.so, parsers/libtree_sitter_go.dylib, parsers/libtree_sitter_go.so, parsers/libtree_sitter_html.dylib.
Installs other software
Following it will install packages (npm, pip, brew or similar). Those come from their own publishers, not from this skill.
How we know
The SKILL.md contains package-install commands.
Partly checked
Launch7’s check could not read everything in this skill: 24 compiled program files it cannot read. Nothing is known about the parts it skipped.
How we know
14 text files read; skipped files are listed by name only. Read 2026-10-05, commit 559a6cd.
Recently maintained
Its repository has had changes recently.
How we know
Last push to oaustegard/claude-skills: 2026-10-02 (3 days before the scan).
Read automatically from the skill’s own files on GitHub on 5 Oct 2026. Launch7 does not run or manually review skills: this lists what the check saw, and nothing here means “safe”. How we check
Add it to your AI
Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.
Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.
In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.
Make sure code execution is switched on (Settings → Capabilities). Skills need it.
Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.
This skill ships 11 scripts beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.
