Upstash QStash — Serverless Message Queues

What it does

This skill turns an agent into an Upstash QStash specialist: it provides patterns, anti-patterns, best-practice guidance for scheduling HTTP-based jobs, reliable webhook delivery, message deduplication, and signature verification. It documents common architectures and operational guidance for durable serverless messaging without owning queue infrastructure.

When to use it

Use when implementing or debugging QStash-based flows: scheduled cron jobs, delayed HTTP callbacks, webhook receivers that must verify signatures, designing deduplication/retry behavior, or integrating QStash with serverless frameworks (Vercel, Cloudflare Workers, Supabase). It is helpful for developers building reliable delivery systems and ops engineers hardening webhook endpoints.

What's included

• Scripts: none bundled.
• References: none bundled in this package, though the repo links related skills and usage examples.
• Instructions: practical patterns for message publishing, scheduling recurring tasks, signature verification, rate-limit and retry considerations, and anti-patterns to avoid.

Compatible agents

Better for developer-assistant agents (Claude/GPT-style) that provide code snippets, architecture advice, and integration patterns. Useful when generating endpoint verification code, deployment checklists, or operational runbooks.
