celery SKILL.md skillA

celery from codeatcode/oss-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add codeatcode/oss-ai-skills/celery@v2.0.0

Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Use when running background tasks with Celery - worker and broker configuration (Redis, RabbitMQ), task routing by name vs queue, chains/groups/chords, retry patterns (autoretry_for, retry_backoff), acks_late semantics, failure detection, and monitoring with Flower.

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

> **Objective:** Use this skill to prevent silent task failures, duplicate executions, and worker crashes in distributed task queues by enforcing idempotency, proper routing, and retry semantics.

# Celery

Distributed task processing with focus on routing, composition, and failure handling.

## When Not to Use Celery

Before adopting Celery, check if you actually need it:

| Scenario | Better Alternative |
|----------|-------------------|
| Short-lived fan-out (5-10 parallel HTTP calls) | Simple thread pool or `asyncio.gather` |
| Single-server Django app with moderate load | Django 6.0+ built-in task queue |
| Work dominated by long IO (10+ min tasks) | Task-per-request model or job queue (dramatiq, huey) |
| Operational overhead unacceptable | django-tasks, RQ, or simple database polling |

**Check before adopting:**
- Do you need multiple workers across machines? (If no → simpler queue)
- Do you have 100+ tasks/minute sustained? (If no → overkill)
- Can you tolerate operational cost (broker + worker fleet + monitoring)? (If no → huey/dramatiq)

## Task Routing and Queue Configuration

### Routing by Task Name (Recommended)

```python
# settings.py or celery.py
…

How to install

The exact contents, by fingerprint
mdr add codeatcode/oss-ai-skills/celery@sha256:f953413c9012d396

The line at the top of this page pins the label v2.0.0, 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.
