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
# Oban Background Jobs Reference
Quick reference for Elixir Oban patterns.
## Oban Pro Detection
**Before applying patterns, check for Oban Pro:**
```bash
grep -E "oban_pro|oban_web" mix.exs
grep -r "use Oban.Pro.Worker" lib/
grep -r "Oban.Pro.Engines.Smart" config/
```
**If Oban Pro detected**, use Pro patterns for ALL new workers:
| Standard Oban | Oban Pro |
|---------------|----------|
| `use Oban.Worker` | `use Oban.Pro.Worker` |
| `def perform(%Job{})` | `def process(%Job{})` |
| `Oban.Testing` | `Oban.Pro.Testing` |
| Advisory lock engine | `Oban.Pro.Engines.Smart` |
**Pro features** (all optional): `args_schema` (typed args), Workflows, Batches, Chunks,
Relay, hooks, encryption, deadlines, chaining, Smart Engine (global concurrency + rate limiting).
Pro plugins (DynamicCron, DynamicLifeline, DynamicPruner) **enhance** OSS equivalents — swap module, don't run both.
See `references/oban-pro-basics.md` for all patterns and migration guide.

## Iron Laws — Never Violate These
1. **JOBS MUST BE IDEMPOTENT** — Safe to retry. Use idempotency keys for payments
2. **JOBS MUST STORE IDs, NOT STRUCTS** — JSON serialization. `%{user_id: 1}` not `%{user: %User{}}`

How to install
mdr add oliver-kriska/claude-elixir-phoenix/oban@sha256:71a68701758e0fbfThe line at the top of this page pins the label git:20260929.c08ad14, 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.
