What is tree-sitter-language-pack?

A plugin that uses tree-sitter, a code parser, to read the structure of programs in 371 programming languages.

Use it for code intelligence, static analysis, extracting program structure, and dividing code into syntax-aware chunks.

It helps coding tools understand imports, symbols, syntax, and code sections instead of treating source files as plain text.

Security

Grade A, and why

tree-sitter-language-pack 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 2d 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.
