Report #2266

[architecture] Why does my ChatGPT action fail to discover or call my API correctly?

Expose a public raw \`openapi.yaml\` \(not just Swagger UI HTML\) with explicit \`servers\`, concise operation summaries under ~120 characters, and security schemes named exactly as configured in the GPT action auth settings. Keep schema property names stable; renaming fields breaks existing user GPT action bindings. Version the spec path, e.g. \`/openapi/v1.yaml\`.

Journey Context:
Teams often serve Swagger UI and assume that satisfies ChatGPT. Actions consume the raw OpenAPI spec, not rendered HTML. Missing \`servers\` or relative URLs cause the model to hallucinate the base URL. Another common failure is changing a property name after users have saved their GPTs; stored bindings then fail silently. Treat the spec as a stable public contract.
