# videos_generate Generate a short video (5-10s) from a text prompt using BytePlus Seedance. Optionally accepts up to 12 image file IDs from the user's attached files (visible in the [ATTACHMENTS] block) as reference_file_ids for style and composition. Returns immediately with a job_id; the video is delivered back via continuation when the job completes (~30-90s for fast model, ~2-5min for pro). Reference images are temporarily re-hosted on a third-party CDN (imgbb) for the duration of generation and deleted on completion — don't submit confidential references.

It is not destructive or financial, but it executes an external process and exfiltrates data to a third-party service, placing it firmly in Execute. From the tool's own definition: "'Generate a short video from a text prompt using BytePlus Seedance' — triggers an external AI video generation job; 'Returns immediately with a job_id; the video is delivered back via continuation when the job completes'; 'reference images are temporarily…" Risk signals: High parameter count (12 properties) ## Use case AI agents invoke videos_generate to trigger actions in Dialogbrain. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
