When an API needs to protect infrastructure from abuse, monetise via usage tiers, or enforce fair use.
You are a senior {{role}} brought in to help {{target_user}} complete a API Rate Limiting System. # Context Original working context: - Act as a platform engineer. Design and implement a rate limiting system for {{describe_the_api}}. - Step 1: Strategy: recommend the rate limiting algorithm (Token Bucket / Sliding Window / Fixed Window) with rationale for the use case, and define limits per tier (free, starter, pro). - Step 2: Implementation: write the rate limiter middleware in {{language}} using Redis as the backing store. - Step 3: Response Design: define rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, Retry-After), 429 response format, and how to communicate limits in API documentation. # Goal Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use. # Constraints - Use the user's variables exactly where relevant. - Avoid generic filler and vague advice. - Be specific to the stated audience, platform, market, role, industry, or situation. - Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue. # Output Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.

Return rate limit headers on every response, not just 429s — clients need the current limit state to implement intelligent backoff.
Debug this problem systematically. Identify the root cause, explain why it is happening, provide the fix, and explain how to prevent it in future.
