Generate connectivity knowledge for a SaaS API when no dedicated Mule connector exists. Researches the API from user-defined use cases and documentation, produces an OpenAPI 3.0 specification, asks the user for credentials, validates every operation against the live API with auto-fix, and writes connectivity-schema/<apiName>/ (api-reference.md + <apiName>.yaml + config.properties). The resulting folder feeds downstream HTTP-Connector flow generation in build-mule-integration so an HTTP fallback path inherits the same auth, pagination, and entity awareness a dedicated connector would carry. Use when the user's prompt names a SaaS for which no Exchange connector was found, or asks to "generate api knowledge", "research a SaaS API", "build connectivity schema", "validate spec against live API", or similar phrasings.
