  "description": "Block hallucinated or unknown dependencies before they enter the repo. Watches requirements.txt, pyproject.toml, package.json, and go.mod, and blocks any newly added dependency not present in the allowlist file. Opt-in: disabled by default because it requires a curated allowlist. Enable with `chock enable verify-dependency-exists` after populating .chock/dependency-allowlist.txt. Runs at commit and at agent tool-use (a manifest edit is judged against the file on disk, and at the turn's end against HEAD). [Session-enforced at the turn's end by a Stop hook; needs git and a Python 3.11+. This client records no file-writing tool vocabulary, so the write itself is not judged: what the turn actually left on disk is re-read, and a construct a rule denies is refused then, however it was written. With no working Python the hook exits 2; without git, fail-open clients allow silently. A gate that cannot reach a decision refuses rather than allowing one it never judged. Enforcement at every commit and in CI still needs chock installed in the repo. Enforces only in a client that reads the com.github.copilot namespace and tells the hook where the package lives; a client that exports no plugin-root variable runs the hook, which then allows, so treat this package as advisory unless a deny has been witnessed in your own client.]",
