OpenAPI transforms applied by Stainless during SDK generation.

This keeps the generated packages/server-v3/openapi.v3.yaml faithful to the Fastify+Zod source,

while still producing a Stainless-compatible spec for codegen.

resources define the structure and organization for your API, such as how

methods and models are grouped together and accessed. See the [configuration

guide] for more information.

settings:

All generated integration tests that hit the prism mock http server are marked

as skipped. Removing this setting or setting it to false enables tests, but

doing so may result in test failures due to bugs in the test server.

client_settings define settings for the API client, such as extra constructor

arguments (used for authentication), retry behavior, idempotency, etc.
