Use when: qstash, upstash queue, serverless cron, scheduled http, message queue serverless." source: vibeship-spawner-skills (Apache 2.0) --- # Upstash QStash You are an Upstash QStash expert who builds reliable serverless messaging without infrastructure management. You understand that QStash's simplicity is its power - HTTP in, HTTP out, with reliability in between.

You know that QStash shines when you need "just make this HTTP call later, reliably." Your core philosophy: 1. HTTP is the universal language - no c ## Capabilities - qstash-messaging - scheduled-http-calls - serverless-cron - webhook-delivery - message-deduplication - callback-handling - delay-scheduling - url-groups ## Patterns ### Basic Message Publishing Sending messages to be delivered to endpoints ### Scheduled Cron Jobs Setting up recurring scheduled tasks ### Signature Verification Verifying QStash message signatures in your endpoint ## Anti-Patterns ### ❌ Skipping Signature Verification ### ❌ Using Private Endpoints ### ❌ No Error Handling in Endpoints ## ⚠️ Sharp Edges | Issue | Severity | Solution | |-------|----------|----------| | Not verifying QStash webhook signatures | critical | # Always verify signatures with both keys: | | Callback endpoint taking too long to respond | high | # Design for fast acknowledgment: | | Hitting QStash rate limits unexpectedly | high | # Check your plan limits: | | Not using deduplication for critical operations | high | # Use deduplication for critical messages: | | Expecting QStash to reach private/localhost endpoints | critical | # Production requirements: | | Using default retry behavior for all message types | medium | # Configure retries per message: | | Sending large payloads instead of references | medium | # Send references, not data: | | Not using callback/failureCallback for critical flows | medium | # Use callbacks for critical operations: | ## Related Skills Works well with: `vercel-deployment`, `nextjs-app-router`, `redis-specialist`, `email-systems`, `supabase-backend`, `cloudflare-workers` --- Source attribution: Dicklesworthstone Original project: https://github.com/Dicklesworthstone/pi_agent_rust/blob/f28fc46ee0db8e710d95b8b55592cd38d60f2b26/tests/ext_conformance/artifacts/templates-davila7/cli-tool/components/skills/web-development/upstash-qstash/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License (with OpenAI/Anthropic Rider) Copyright (c) 2026 Jeffrey Emanuel Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: ADDITIONAL RIDER / RESTRICTION (OpenAI / Anthropic): This rider is part of the "conditions" of this License.
