    API Evolution & Compatibility Toolkit

    Design, extend, document, repair, and retire APIs while preserving compatibility for existing clients. This bundle covers endpoint creation, REST design, documentation, pagination contracts, rate-limit contracts, GraphQL nullability, webhook signatures, and safe API retirement. Use it when APIs evolve across multiple clients and seemingly small contract changes can break integrations, SDKs, automation, or customer workflows.

    You say

    We need to retire our v1 REST API by December. We have 400 active integrations. The v2 uses OAuth2 instead of API keys. Help me plan the migration and identify risks.

    Your agent does

    API Retirement Decision: Proceed. Risk Score: 7. Summary: High risk due to auth change for 400 consumers. Breaking Change: API Keys to OAuth2 requires customer code updates. Status: Ready for waves.
