What it does

Upstash Ratelimit is an agent skill from sickn33/agentic-awesome-skills. Add rate limiting to API routes, middleware, and edge functions with @upstash/ratelimit: sliding window, fixed window, and token bucket backed by Upstash Redis.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Rate limiting and Serverless. It works with Upstash and Redis. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit b84d35a. 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
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- upstash.com
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- UPSTASH_REDIS_REST_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Upstash Ratelimit loads about 1.7k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 616 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~45
When it runs · the whole SKILL.md, loaded when a task matches: ~1.7k

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.

Upstash Ratelimit

Overview

@upstash/ratelimit implements distributed rate limiting on top of Upstash Redis. Because state lives in Redis, every instance of a serverless function or edge worker shares the same counters, which an in-memory limiter cannot do. It ships three algorithms (fixed window, sliding window, token bucket), per-identifier keys, optional in-memory blocking of already-limited identifiers, and optional analytics.

When to Use This Skill

Use when the user needs to limit requests per IP, user, API key, or tenant across multiple serverless instances or regions.
Use when protecting login, signup, form, webhook, or LLM endpoints from abuse and returning 429 Too Many Requests.
Use when choosing between fixed window, sliding window, and token bucket.
Do not use for client-side retry/backoff against a third-party API's limits; see api-rate-limit-handler.
Do not use for a single long-running process with no shared state; an in-memory limiter is simpler there.

How It Works

Step 1: Install and configure

bash

npm install @upstash/ratelimit @upstash/redis

Set UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN in the environment.

Step 2: Create the limiter once, outside the handler

typescript

import { Ratelimit } from "@upstash/ratelimit";
import { Redis } from "@upstash/redis";

export const ratelimit = new Ratelimit({
  redis: Redis.fromEnv(),
  limiter: Ratelimit.slidingWindow(10, "10 s"), // 10 requests per 10 seconds
  prefix: "rl:api",
  analytics: true,
});

Constructing the limiter at module scope lets the built-in ephemeral cache short-circuit blocked identifiers without a Redis call.

Step 3: Call `limit()` with a stable identifier

typescript

const { success, limit, remaining, reset, pending } = await ratelimit.limit(userId);

success is false when the identifier is over its limit. reset is a Unix timestamp in milliseconds. pending is a promise for background work (analytics, multi-region sync); await it or pass it to waitUntil on edge runtimes so the function is not frozen before it completes.

Examples

Example 1: Next.js middleware returning 429

typescript

import { Ratelimit } from "@upstash/ratelimit";
import { Redis } from "@upstash/redis";
import { NextResponse, type NextRequest } from "next/server";

const ratelimit = new Ratelimit({
  redis: Redis.fromEnv(),
  limiter: Ratelimit.slidingWindow(20, "1 m"),
});

export async function middleware(request: NextRequest) {
  const ip = request.headers.get("x-forwarded-for") ?? "anonymous";
  const { success, limit, remaining, reset } = await ratelimit.limit(ip);

  if (!success) {
    return new NextResponse("Too Many Requests", {
      status: 429,
      headers: {
        "X-RateLimit-Limit": String(limit),
        "X-RateLimit-Remaining": String(remaining),
        "X-RateLimit-Reset": String(reset),
        "Retry-After": String(Math.ceil((reset - Date.now()) / 1000)),
      },
    });
  }
  return NextResponse.next();
}

export const config = { matcher: "/api/:path*" };

Example 2: Token bucket with per-plan limits

typescript

const limiters = {
  free: new Ratelimit({
    redis: Redis.fromEnv(),
    prefix: "rl:free",
    limiter: Ratelimit.tokenBucket(5, "10 s", 10), // refill 5 per 10 s, burst 10
  }),
  pro: new Ratelimit({
    redis: Redis.fromEnv(),
    prefix: "rl:pro",
    limiter: Ratelimit.tokenBucket(50, "10 s", 100),
  }),
};

const { success } = await limiters[plan].limit(apiKey);

Best Practices

✅ Use a stable, low-cardinality identifier (user id, API key, tenant) where possible; fall back to IP only for anonymous traffic.
✅ Set a distinct prefix per endpoint or plan so limits do not collide.
✅ Return Retry-After and X-RateLimit-* headers with 429 responses.
✅ Prefer slidingWindow for most APIs; use tokenBucket when short bursts are acceptable; use fixedWindow when the lowest Redis cost matters.
❌ Don't construct a new Ratelimit inside the request handler.
❌ Don't rely on pending completing on its own in edge runtimes.
❌ Don't rate limit by x-forwarded-for without validating it is set by your proxy; clients can spoof it otherwise.

Limitations

Requires an Upstash Redis database; it does not work with other Redis servers or without network access.
Each limit() call is at least one HTTP round trip to Redis, so it adds latency to every request it guards.
Sliding window is an approximation that assumes an even spread of requests in the previous window; it is not an exact log.
MultiRegionRatelimit trades strict accuracy for lower latency and does not support the token bucket algorithm.
If Redis is unreachable, the default timeout (5 s) lets requests through (reason: "timeout"); this fails open, not closed.
This skill does not replace environment-specific validation, testing, or expert review.

Security & Safety Notes

Rate limiting is one layer of abuse protection, not authentication. Pair it with auth and input validation.
The Redis token grants full database access; keep it server-side.
Changing limits in production can lock out legitimate users. Confirm the numbers with the user before deploying stricter limits.

Common Pitfalls

Problem: Every request is allowed even after the limit. Solution: Each identifier must be the same string across requests; check that the identifier is not undefined or a fresh random value.
Problem: Analytics are empty on Vercel Edge or Cloudflare Workers. Solution: Pass pending to waitUntil (ctx.waitUntil(pending)) so the background request is not cancelled when the response is sent.

@upstash-redis - The client this package uses for storage.
@api-rate-limit-handler - Client-side backoff and retry when you are the one being rate limited.
@upstash-qstash - Queue and smooth traffic to downstream services instead of rejecting it.
