Design a provider-side outbound webhook platform - event taxonomy and catalog, payload envelope and schema versioning, an HMAC signing scheme (Standard Webhooks), at-least-once delivery with retry/backoff and dead-letter policy, subscription lifecycle states, and the developer-facing debugging surface (delivery logs, replay, test-event triggering). Use whenever the user mentions webhooks, event callbacks, push events to customer endpoints, webhook signatures, delivery retries, or a webhook consumer portal - even if they never say "webhook platform". Provider side only. Do NOT use for consumer-side retry mechanics - use samber/developer-platform-skills@api-idempotency-retry instead.
Decide which integration surfaces a platform offers external developers and AI agents - REST, GraphQL, gRPC, SQL access, bulk data sharing, webhooks, SDKs, CLI, MCP, embedded components - and in what build order, sequenced by reversal cost and audience rather than novelty. Use whenever the user mentions which API to build first, adding a GraphQL or MCP layer, an integration-surface roadmap, API-first vs embedded-first, or a missing surface blocking deals - even if they never say "integration surface". Umbrella strategy only - once a surface is chosen, per-surface design belongs to siblings such as samber/developer-platform-skills@webhook-platform-design and samber/developer-platform-skills@sdk-portfolio-strategy.
Design idempotency-key support and client retry guidance for a public API so integrators retry safely - key derivation and per-caller scoping, storage TTL and replay windows, atomic claim mechanisms (DB unique constraint, SERIALIZABLE row lock, conditional writes), payload-mismatch rejection, in-flight duplicate handling, exponential backoff with jitter, retry budgets, timeout propagation, and SDK retry defaults. Use whenever the user mentions an Idempotency-Key header, duplicate or double-submitted requests, safe POST retries, backoff, or jitter - even if they never say "idempotency". Do NOT use for what the error response signals (samber/developer-platform-skills@api-error-design) or webhook delivery retries (samber/developer-platform-skills@webhook-platform-design).
