1. Always verify environment first — run check_env.py before any other operation to catch missing dependencies or credentials early. 2. Auto-detect workspace_id — always fetch workspaces via list-workspaces; default to the first result, but present a selection list when the user explicitly asks to choose. 3. Use default OSS settings — unless the user specifies a particular bucket, let the script auto-detect the bucket and generate the oss object key. 4. Display partial results during polling — when task status is RUNNING, show available results (title, captions) to give the user real-time feedback. 5. Save complete result for summary — when status becomes SUCCESSED, use the full result payload directly for Step 6 without re-calling the API. 6. Respect URL expiration — temporary OSS URLs expire after expireSeconds (default 14400s); ensure the task is submitted before the URL expires. 7. Handle permission errors gracefully — follow the Permission Failure Handling process in the RAM Policy section; never improvise credential fixes.
