IMPORTANT ASYNCHRONOUS TASK WORKFLOW
- Call this MCP generation tool once and read taskId from structuredContent.
- Do not call generation again while pending or running.
- Query nexscope_media_task_result with this skill slug, the exact taskId, and the same bearer credential using progressive backoff.

Asynchronous task workflow
- 1. Create once
Keep the returned taskId.
- 2. Query with backoff
Use nexscope_media_task_result after 5 seconds, then 10, 20, and 30 seconds.
- 3. Use final result
Stop at success, failure, or timeout.
