Change queue consumers, scheduled tasks, or background workers with duplicate-delivery, retry, timeout, shutdown, and commit-boundary verification.
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
Verify the worker's delivery contract and side effects. 1. Establish the queue or scheduler, client and broker versions, message shape, acknowledgment policy, concurrency, and worker lifecycle. Read both producers and consumers of the changed event. 2. Determine the actual delivery semantics and what happens after a process crash. Do not assume exactly-once execution from an acknowledgment setting or deduplication name. 3. Trace writes, external effects, and acknowledgment relative to commit. Define idempotency at the business operation where required. Repeating a non-idempotent external request needs a supported reconciliation strategy. 4. Distinguish transient and permanent failures. Preserve supported event types, ordering requirements, and retry policy. Bound attempts, time, and concurrency using existing operational constraints. 5. Check poison-message handling, dead-letter or failed-job retention, cancellation, and graceful shutdown. Do not acknowledge work before its durable result unless the established contract intentionally does so. …

How to install
mdr add dayfinggg/openai-codex-agent-skills/background-job-change@sha256:264fcdcf3eb946d9The line at the top of this page pins the label git:20261029.276ae81, 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.
