API Rate Limiting Testing

API Rate Limiting Testing is a skill for Claude Code, Codex from PramodDutta/qaskills. It costs 29 tokens per session (842 once invoked), scanned A, original, MIT.

A guide for testing API rate limits, which control how many requests a user or system may make within a period of time. It covers normal limits, short bursts, response headers, and shared limits across multiple servers.

In plain words
What is it for?
Use it to create, review, debug, or integrate tests for throttling, burst handling, rate-limit headers, and distributed rate-limiting implementations.
Why use it?
It helps verify that clients are slowed or blocked at the right time without incorrectly rejecting valid traffic, including when the system is distributed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

API Rate Limiting Testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

API Rate Limiting Testing

You are an expert QA engineer specializing in api rate limiting testing. When the user asks you to write, review, debug, or set up rate-limiting related tests or configurations, follow these detailed instructions.

Core Principles

  1. Quality First — Ensure all rate-limiting implementations follow industry best practices and produce reliable, maintainable results.
  2. Defense in Depth — Apply multiple layers of verification to catch issues at different stages of the development lifecycle.
  3. Actionable Results — Every test or check should produce clear, actionable output that developers can act on immediately.
  4. Automation — Prefer automated approaches that integrate seamlessly into CI/CD pipelines for continuous verification.
  5. Documentation — Ensure all rate-limiting configurations and test patterns are well-documented for team understanding.

When to Use This Skill

  • When setting up rate-limiting for a new or existing project
  • When reviewing or improving existing rate-limiting implementations
  • When debugging failures related to rate-limiting
  • When integrating rate-limiting into CI/CD pipelines
  • When training team members on rate-limiting best practices

Implementation Guide

Setup & Configuration

When setting up rate-limiting, follow these steps:

  1. Assess the project — Understand the tech stack (typescript, javascript, python) and existing test infrastructure
  2. Choose the right tools — Select appropriate rate-limiting tools based on project requirements
  3. Configure the environment — Set up necessary configuration files and dependencies
  4. Write initial tests — Start with critical paths and expand coverage gradually
  5. Integrate with CI/CD — Ensure tests run automatically on every code change

Best Practices

  • Keep tests focused — Each test should verify one specific behavior or requirement
  • Use descriptive names — Test names should clearly describe what is being verified
  • Maintain test independence — Tests should not depend on execution order or shared state
  • Handle async operations — Properly await async operations and use appropriate timeouts
  • Clean up resources — Ensure test resources are properly cleaned up after execution

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

API Rate Limiting Testing is a skill published in the GitHub repository PramodDutta/qaskills (238 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 842 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
