.agents/skills/cli/SKILL.md

cli is a skill for Claude Code, Codex from xberg-io/tree-sitter-language-pack. It costs 12 tokens per session (263 once invoked), scanned A, original, MIT.

A command-line reference for tree-sitter-language-pack, a tool that parses source code and extracts information about its structure.

In plain words
What is it for?
Use it when running or documenting commands such as listing languages, parsing files, processing code, or starting its MCP server.
Why use it?
It gives agents the commands needed to inspect languages, download parsers, parse files, and run the code-intelligence pipeline.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is xberg-io/tree-sitter-language-pack's own configuration. It tells Claude Code and Codex how to work on tree-sitter-language-pack itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything tree-sitter-language-pack configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
