  "description": "Refuses agent-memory writes that hold what memory must never hold: pasted git history (diff headers, hunk headers, commit and index lines), a fenced code block longer than 20 lines, a line that duplicates another, and secrets (scan-secrets' pattern). Judges only memory files -- MEMORY.md at any depth, CLAUDE.local.md, .claude/memory/**, memory/**/*.md, and at agent tool-use the agent's own stores outside the repository (~/.claude/projects/*/memory/**, ~/.claude/CLAUDE.md, /memories/**) -- and only what the change adds. No waiver exists. Mechanised slice of memory-discipline's never_persist and chock-mise's never(store): secrets. Structural checks only. [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.]",
