Plan and validate a data-backed service

How these skills work together

Map the user task to the service, database and deployment boundaries. Review schema and query decisions with the PostgreSQL reference. If the runtime is Cloudflare Workers, inspect its actual bindings, compatibility settings and failure behavior. Validate the complete request path after publication. These sources cover adjacent responsibilities; using the kit does not imply every project needs Cloudflare or that the components were tested together by this catalog.

Validation and boundaries

Test representative data, allowed and denied access, service failures, migration recovery and the public response. Keep secrets in the platform's established storage and use the project's approved release process. A passing query or successful build alone is not the complete acceptance result.
