Use when implementing, fixing, or reviewing asynchronous or long-lived behavior involving background tasks, thread pools, scheduled jobs, message-queue consumers such as Kafka, terminal sessions, subprocesses, retries, cancellation, timeouts, shutdown, or resource cleanup. Establish explicit ownership and state transitions, make retry and disposal safe, and verify failure and restart paths instead of only the successful call.

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

# Rumo Lifecycle Safety

Make every long-lived operation answer who owns it, when it becomes visible, how it stops, and what remains after failure. Apply `rumo-coding-guidelines` before changing code and use `rumo-review` for a review-only request.

## Establish Authority

Trace the production path from creation through publication, use, cancellation, completion, and disposal. Identify:

- the authoritative state and every derived cache, UI status, Redis key, database row, queue message, or in-memory registry;
- the component that creates the work and the component responsible for stopping and releasing it;
- the stable operation or task identity used across retries, reconnects, and process restarts;
- the thread, executor, scheduler, event loop, process, or remote service on which each transition occurs;
- the observable state that means ready, completed, failed, cancelled, timed out, or abandoned.

Do not infer readiness from service presence, object construction, a submitted future, an HTTP success status, or a process identifier alone. Use the event or state owned by the mechanism being awaited.

## Define The State Machine

How to install

The exact contents, by fingerprint
mdr add rumoii/rumo-engineering-skills/rumo-lifecycle-safety@sha256:0a910f54fcdaa064

The line at the top of this page pins the label git:20261026.bef6e05, 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.
