Background Jobs & Queues

What it does

Designs reliable background jobs and queues: retries, idempotency, ordering, dead-letter handling, recovery.

When to use it

Use for asynchronous processing, scheduled work, or recovering safely from a partial job failure.

Problems it prevents

Stops a retried job silently double-processing the same request because it was never made idempotent.

Typical workflow

1. Define the job's contract and guarantees
2. Handle concurrency and failure safely
3. Build operator controls and dead-letter handling
4. Verify recovery from partial failure

Example output

A retried background job that provably processes the same request exactly once, with a dead-letter path for the rest.

What's included

1. 01
   The complete prompt

   The full manual as a ready-to-save SKILL.md file, matched exactly to what ships in the T7 library.

2. 02
   Install walkthrough

   Personal (~/.claude/skills/) and project (.claude/skills/) folder instructions, whichever fits how you work.

3. 03
   Use notes

   How Claude invokes it, what a good result looks like, and what to check before you trust the output.

Works well with

• SystemObservability & Incident Response

  Designs production telemetry, alerting, runbooks and incident command so problems are caught and handled fast.

• FocusedOffline & Reconnection

  Implements resilient offline, retry and reconnection behaviour so a dropped connection never loses work.

• SystemTransactional Email Deliverability

  Designs secure, reliable transactional email: sender setup, idempotent triggers, bounce and suppression handling.
