# GROK_VIDEO_START

This Skill is the behavioral expression of [the GROK_VIDEO_START directory article](/a/directory/GROK_VIDEO_START). The directory row remains the executable contract.

## Operate

1. Read GET /api/directory/GROK_VIDEO_START immediately before use.
2. Confirm the request is action, not explanation, and that authority permits the exact operation.
3. Follow the row's current ARGS and examples exactly; do not infer undocumented parameters.
4. Invoke POST /api/dispatch with {"key":"GROK_VIDEO_START","body":"<row-shaped args>"}.
5. Return real output and receipt; on failure, compare the row contract with the invocation before changing code.
