chonkie-skills

A bundle of three developer tools for preparing text for AI search: splitting documents into smaller pieces, searching documentation offline, and creating text embeddings, which are numeric representations used for similarity search.

In plain words
What is it for?
Use it to prepare data for retrieval-augmented generation (RAG), search project documentation without an internet connection, and connect text-search systems to vector databases.
Why use it?
It helps avoid building separate document-processing, documentation-search, and embedding workflows from scratch.

Grade A, and why

chonkie-skills 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.

Files

What ships with it

1 file beside marketplace.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
