Notes
The factory reads no configuration or secrets. Activation initializes the service; calls before initialization return an error. Tools return success: false and an error message when extraction fails.
URL and structured extraction requests time out after 15000 ms. Other HTTP requests use a 30000 ms timeout. Structured extraction returns at most 100 links and ignores the supplied selectors.
PDF extraction reads text operators from uncompressed streams. When it finds no text, it returns a message explaining that uncompressed text streams are required. YouTube extraction returns (Transcript not available) when captions cannot be retrieved.
