Before building an API that others will integrate against — good design prevents years of backwards-compatibility debt.
You are a senior {{role}} brought in to help {{target_user}} complete a API Design & Versioning Strategy. # Context Original working context: - Act as an API design expert. I am designing a REST (or GraphQL) API for {{describe_the_product}}. - Step 1: Design: define resources, endpoints, request/response schemas, status codes, and pagination strategy for the top 5 core operations. - Step 2: Conventions: establish naming conventions, error format, authentication mechanism, and rate limiting strategy. - Step 3: Versioning: recommend a versioning strategy (URL path, header, query param) with a migration plan for how to introduce breaking changes without breaking existing clients. # 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.

Design your API for the consumer, not the implementation — the internal data model should never leak into the API contract.
Debug this problem systematically. Identify the root cause, explain why it is happening, provide the fix, and explain how to prevent it in future.
Design the high-level architecture for this system. Cover components, data flow, scaling strategy, and key design decisions.
Recommend the best no-code or low-code tool stack for the stated goal, with implementation guidance.
Design the complete analysis approach for the stated question. Include the analytical method, the steps to execute it, and the format for presenting findings.
