state-mutation-locking SKILL.md skillA
state-mutation-locking from baphuongna/pi-crew is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add baphuongna/pi-crew/state-mutation-locking@git:20260911.c97bc57Pins git:20260911.c97bc57 in mdr.lock. Pin the fingerprint instead.

Durable state mutation and locking workflow. When NOT to use: read-only inspection (use runtime-state-reader); single-process non-concurrent edits.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# state-mutation-locking Use this skill before modifying pi-crew run state. ## Source patterns distilled - `src/state/locks.ts` — run-level sync/async locks - `src/state/state-store.ts` — manifest/tasks persistence - `src/state/contracts.ts` — allowed status transitions - `src/state/mailbox.ts`, `src/state/task-claims.ts`, `src/state/atomic-write.ts` - `src/runtime/crash-recovery.ts`, `src/runtime/stale-reconciler.ts`, `src/runtime/team-runner.ts` ## Rules - Mutations to a run's `manifest.json`, `tasks.json`, mailbox delivery state, claims, or recovery status must be protected by a run lock when concurrent actions are possible. - Re-read manifest/tasks inside the lock before making a decision; pre-lock reads are only for locating the run. - Persist with atomic write helpers (`atomicWriteJson`, async variants, or state-store helpers). Do not partially write JSON files. - Respect status contracts. Do not transition terminal tasks/runs unless the action explicitly supports force semantics. - Separate analysis from persistence: pure reconcilers should return intended repaired state; locked callers should persist it. …

How to install
mdr add baphuongna/pi-crew/state-mutation-locking@sha256:d1b9bb6ea8526e9aThe line at the top of this page pins the label git:20260911.c97bc57, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
