What it does

Qstash JS is an agent skill from upstash/qstash-js, published by the product's own GitHub organization. Work with the QStash JavaScript/TypeScript SDK for serverless messaging, scheduling. Use when publishing messages to HTTP endpoints, creating schedules, managing queues, verifying incoming messages in serverless environments.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files (for example `advanced/callbacks.md`, `advanced/deduplication.md` and `advanced/dlq.md`).

It sits in Backend & APIs, covering Serverless. It works with Upstash, JavaScript, TypeScript and Next.js. The repository describes itself as: Message queue for serverless. The licence is MIT.

When your agent uses it

Publishing messages to HTTP endpoints
Creating schedules
Managing queues
Verifying incoming messages in serverless environments

Example prompts

“/qstash-js”

Requirements

Node.js
A credential in QSTASH_TOKEN

What it can do on your machine

Read from SKILL.md and the folder at commit 140e979. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (TypeScript), which the agent can run.
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- QSTASH_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Qstash JS loads about 746 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~59
When it runs · the whole SKILL.md, loaded when a task matches: ~746

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

QStash JavaScript SDK

QStash is an HTTP-based messaging and scheduling solution for serverless and edge runtimes. This skill helps you use the QStash JS SDK effectively.

When to use this skill

Use this skill when:

Publishing HTTP messages to endpoints or URL groups
Creating scheduled or delayed message delivery
Managing FIFO queues with configurable parallelism
Verifying incoming webhook signatures from QStash
Implementing callbacks, DLQ handling, or message deduplication

Quick Start

Installing the SDK

bash

npm install @upstash/qstash

Basic Publishing

typescript

import { Client } from "@upstash/qstash";

const client = new Client({
  token: process.env.QSTASH_TOKEN!,
});

const result = await client.publishJSON({
  url: "https://my-api.example.com/webhook",
  body: { event: "user.created", userId: "123" },
});

Core Concepts

For fundamental QStash operations, see:

For verifying incoming messages:

Receiver Verification - Core signature verification with the Receiver class
Platform-Specific Verifiers:
- Next.js - App Router, Pages Router, and Edge Runtime

For advanced features:

Callbacks
Dead Letter Queue (DLQ)
Message Deduplication
Region migration & multi-region support
- If needed, multi-region env variable setup verification script. Can be run without arguments

Platform Support

QStash JS SDK works across various platforms:

Next.js (App Router and Pages Router)
Cloudflare Workers
Deno
Node.js (v18+)
Vercel Edge Runtime
SvelteKit, Nuxt, SolidJS, and other frameworks

Note on Workflow SDK: For building complex durable workflows that chain multiple QStash messages together, consider using the separate QStash Workflow SDK (@upstash/workflow). The Workflow SDK empowers you to orchestrate multi-step processes with automatic state management, retries, and fault tolerance. This Skills file focuses on the core QStash messaging SDK.

Best Practices

Always verify incoming QStash messages using the Receiver class
Use environment variables for tokens and signing keys
Set appropriate retry counts and timeouts for your use case
Use queues for ordered processing with controlled parallelism
Implement DLQ handling for failed message recovery
