IMPORTANT ASYNCHRONOUS TASK WORKFLOW
- Call this MCP generation tool once and read taskId from structuredContent.
- Do not call the generation tool again while the task is PENDING or RUNNING.
- Wait at least 5 seconds, then call nexscope_media_task_result with skillSlug set to print-pattern-extraction, the exact taskId, and the same bearer API key. While the task remains PENDING or RUNNING, use 5, 10, 20, and 30-second progressive backoff. Never query more often than once every 5 seconds.
- Stop querying when the task succeeds or fails. On success, return the final Nexscope resource URLs and the returned count as the actual charged credits.
- Never invent a taskId and never expose internal provider names or provider resource URLs.

This capability uses a create-and-query flow. Creating the task and retrieving its final generated resources are two connected requests.
- 1. Create onceCall the MCP tool once and keep the returned
taskId. - 2. Query with backoffCall

Use final resultStop at a terminal status. Successful results contain Nexscope resource URLs and the actual charged-credit count.
