Report #97269

[architecture] ChatGPT rejects my OpenAPI schema or says 'No operations found' when adding an Action

Use OpenAPI 3.1.0, set a single absolute HTTPS \`servers.url\`, give every operation a unique \`operationId\`, keep \`summary\` under ~100 characters, and declare security schemes explicitly. Operation descriptions are the prompt the model sees, so write them as imperative instructions.

Journey Context:
OpenAI's action parser is stricter than a generic validator. Relative server URLs, missing operationIds, or 3.0.x specs often fail silently. Descriptions and summaries become the model's tool-use instructions, so vague copy causes poor invocation. Many developers treat the OpenAPI doc as API documentation; for agents it is the system prompt for tool selection.
