What upstash-qstash does

This skill gives Claude working knowledge of QStash — publishing messages, scheduling calls, recurring cron tasks, deduplication and callbacks. It ships as patterns plus a table of sharp edges: signature checks, URL groups, error handling inside the endpoint.

The idea behind it is simple. HTTP goes in, HTTP goes out, and QStash handles the reliability in between. That is why signature verification with both keys gets its own section, and why the endpoint should acknowledge fast — a slow response breaks delivery. Turn on deduplication for operations you cannot repeat, and set retries per message type instead of accepting the default.

One hard limit: QStash cannot reach private or localhost endpoints. Your handler has to be publicly reachable. Sending a reference beats stuffing a large payload into the message body.

What it helps with

  • schedule an HTTP call for later without running your own worker
  • set up a recurring cron task in a serverless project
  • verify the signature on an incoming QStash webhook
  • stop the same message from being processed twice
  • debug why an endpoint never receives its messages

Example prompts for the agent

  • Schedule a webhook delivery through QStash 10 minutes from now
  • Add QStash signature verification to my api/webhook/route.ts handler
  • Create a QStash cron job that hits my endpoint once an hour

How do I install upstash-qstash in Claude Code?

Use the templates CLI: npx claude-code-templates@latest --skill web-development/upstash-qstash. Or run npx skills add davila7/claude-code-templates --skill upstash-qstash -a claude-code. The skill file then lives at ~/.claude/skills/upstash-qstash/SKILL.md.

What does the upstash-qstash skill do?

It teaches the agent QStash: message publishing, delayed HTTP calls, serverless cron, webhook delivery, deduplication and callbacks. It also covers mistakes like skipping signature verification.

Can QStash reach a local server during development?

No. Private and localhost addresses are out of reach, so testing needs a publicly available endpoint.
