API Rate Limit Handler

Overview

A skill for implementing production-grade rate limiting, exponential backoff, and retry strategies when integrating with external APIs. Prevents cascading failures, respects upstream quotas, and keeps your application resilient under load.

When to Use This Skill

• Use when calling external APIs that enforce rate limits (OpenAI, Stripe, GitHub, etc.)
• Use when you receive 429 Too Many Requests or 5xx errors and need graceful recovery
• Use when building a client that must respect Retry-After headers
• Use when designing a system that fans out to multiple API providers
• Use when the user says "handle rate limits", "add retry logic", "backoff strategy", or "don't get throttled"

How It Works

Step 1: Classify the response

Determine whether a failed request is retryable or terminal.
