freeze — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited freeze (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Toggle a project-local edit lock so Claude can only modify the files you intend during a focused task (debugging, a tight refactor, a review pass). Enforced by the freeze-gate.sh PreToolUse hook, which denies Edit/Write/NotebookEdit outside the allow-list. No sentinel = no lock; the hook stays dormant.
The lock lives in .claude/.freeze — one allowed path prefix per line, project-relative. Empty file = freeze everything.
/phx:freeze [args] — resolve $ARGUMENTS and run the matching Bash branch.
| Invocation | Effect |
|---|---|
/phx:freeze | Freeze ALL edits — read-only investigation mode |
/phx:freeze lib/app_web priv/repo | Allow edits only under these dirs |
/phx:freeze status | Show current lock state |
/phx:freeze off | Lift the lock (delete the sentinel) |

lib/foo allowslib/foo and everything under it; it does NOT allow lib/foobar.
surfaces clearly instead of failing silently.
/phx:investigate (freeze all while root-causing) and /phx:work(scope to the plan's dirs). The lock is advisory tooling, not a security boundary — anyone can run /phx:freeze off.
