ChatGPT app developers can generate chatgpt-app-submission.json even when their MCP tools omit optional outputSchema fields, but those missing schemas make tool results less structured for models that consume them. Update the chatgpt-app-submission skill so it records tools whose descriptors or source definitions omit outputSchema or set it to null, then reports a concise final-response warning with the MCP tool spec link. The warning is intentionally non-blocking and stays out of the generated submission JSON. Bump the chatgpt-apps plugin version because the packaged skill content changed.

Why
ChatGPT app developers can generate
chatgpt-app-submission.jsoneven when their MCP tools omit the optionaloutputSchemafield. That should stay non-blocking, but the generated handoff should still point out missing output schemas because they give models more structure for using tool results.What changed
The
chatgpt-app-submissionskill now records tools whose descriptors or source definitions omitoutputSchemaor set it tonull. The generated JSON remains unchanged, and the skill reports a concise final-response warning with the affected tool names and a link to the MCP tool spec.The
chatgpt-appsplugin manifest version is bumped from0.1.0to0.1.1because the packaged skill content changed.
