upstash-qstash
Upstash QStash expert for serverless message queues, scheduled jobs, and reliable HTTP-based task delivery without managing infrastructure.
Profile →npx skills add sickn33/agentic-awesome-skills --skill upstash-qstash --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
What it does
Guides an agent to implement and manage Upstash QStash-based workflows, including sending messages, scheduling, webhook verification, delivery callbacks, URL group fan-out, deduplication, and handling common edge cases. Emphasizes reliability, signatures verification, and observability through callbacks and status updates.
How it works
- Provides examples and patterns for:
- Basic message publishing with optional delay
- Scheduled cron-like jobs via QStash schedules
- Signature verification for incoming webhooks using Receiver with current and next signing keys
- Callbacks and failure callbacks to receive delivery status
- URL groups to broadcast to multiple endpoints
- Message deduplication using deduplicationId and contentBasedDeduplication
- Shows configuration and runtime usage via the qstash-sdk in several frameworks and environments (Next.js, Cloudflare Workers, Vercel, AWS Lambda, Netlify Functions)
- Demonstrates defensive and operational patterns:
- Fast webhook responses to avoid timeouts
- Offloading heavy work to subsequent messages or queues
- Handling rate limits, retries, and batch publishing
- Ensuring endpoints are public and HTTPS is used
- Includes Notable edge-cases and mitigations for:
- Verifying signatures with two keys during rotation
- Avoiding localhost or private endpoints for public QStash reachability
- Managing large payloads by sending references instead of full documents
- Configuring per-message retries and backoff strategies
When to use it
- When you need reliable, serverless HTTP-based task delivery without managing infrastructure
- When initial integration requires scheduled or delayed tasks, webhook delivery, and deduplication for idempotent processing
- When you must verify inbound webhook signatures and track delivery outcomes via callbacks
- When sending to multiple endpoints or requiring URL groups and structured retry logic
What it can touch
- Interacts with Upstash QStash via the qstash-sdk
- Uses public HTTP(S) endpoints for delivery
- May require environment variables for QStash tokens and signing keys
Caveats
- Declared risk: critical
- Notable risk areas include not verifying QStash webhook signatures, potential heavy processing in callbacks causing timeouts, and rate-limit handling requirements
- Requires endpoints to be publicly accessible over HTTPS; localhost or private IPs are not reachable by QStash
- Large payloads should be avoided; prefer sending references and fetching data in the handler
# Upstash QStash Upstash QStash expert for serverless message queues, scheduled jobs, and reliable HTTP-based task delivery without managing infrastructure. ## Principles - HTTP is the interface - if it speaks HTTPS, it speaks QStash - Endpoints must be public - QStash calls your URLs from the cloud - Verify signatures always - never trust unverified webhooks - Schedules are fire-and-forget - QStash handles the cron - Retries are built-in - but configure them for your use case - Delays are free - schedule seconds to days in the future - Callbacks complete the loop - know when delivery succeeds or fails - Deduplication prevents double-processing - use message IDs ## Capabilities - qstash-messaging - scheduled-http-calls - serverless-cron - webhook-delivery - message-deduplication - callback-handling - delay-scheduling - url-groups ## Scope - complex-workflows -> inngest - redis-queues -> bullmq-specialist - event-sourcing -> event-architect - workflow-orchestration -> temporal-craftsman ## Tooling ### Core - qstash-sdk - upstash-console ### Frameworks - nextjs - cloudflare-workers - vercel-functions - aws-lambda - netlify-functions ### Patterns - scheduled-jobs - delayed-messages -

What does the upstash-qstash skill do?
Upstash QStash expert for serverless message queues, scheduled jobs, and reliable HTTP-based task delivery without managing infrastructure.
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill upstash-qstash --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
