bullmq-specialist is a skill for Claude Code, Codex from aboalrejal-ai/skills. It costs 29 tokens per session (2,355 once invoked), scanned A, original, MIT.

A specialist guide for BullMQ, a Node.js and TypeScript library that runs background jobs through Redis queues.

In plain words
What is it for?
Building job queues, workers, delayed or recurring jobs, job dependencies, concurrency limits, and graceful shutdowns in Node.js or TypeScript.
Why use it?
It helps structure asynchronous work so jobs can be scheduled, retried, rate-limited, prioritized, and handled safely when they fail.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bullmq-specialist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

BullMQ Specialist

BullMQ expert for Redis-backed job queues, background processing, and reliable async execution in Node.js/TypeScript applications.

Principles

  • Jobs are fire-and-forget from the producer side - let the queue handle delivery
  • Always set explicit job options - defaults rarely match your use case
  • Idempotency is your responsibility - jobs may run more than once
  • Backoff strategies prevent thundering herds - exponential beats linear
  • Dead letter queues are not optional - failed jobs need a home
  • Concurrency limits protect downstream services - start conservative
  • Job data should be small - pass IDs, not payloads
  • Graceful shutdown prevents orphaned jobs - handle SIGTERM properly

Patterns

Basic Queue Setup

Production-ready BullMQ queue with proper configuration

When to use: Starting any new queue implementation

import { Queue, Worker, QueueEvents } from 'bullmq'; import IORedis from 'ioredis';

// Shared connection for all queues const connection = new IORedis(process.env.REDIS_URL, { maxRetriesPerRequest: null, // Required for BullMQ enableReadyCheck: false, });

// Create queue with sensible defaults const emailQueue = new Queue('emails', { connection, defaultJobOptions: { attempts: 3, backoff: { type: 'exponential', delay: 1000, }, removeOnComplete: { count: 1000 }, removeOnFail: { count: 5000 }, }, });

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
