Storyboard Grid Writer

Use When

• A controller needs a storyboard grid, beat panel plan, contact sheet, or panel prompt pack.
• Hook logic must become visible frame-by-frame action before image or video generation.
• The output should hand off to image-generation or video-request-architect.

Do Not Use When

• The final provider request is already approved. Use the runner.
• Reference meaning or copy boundaries are unresolved. Use reference-decode or reference-contract-builder.
• The user wants plain prose, a script only, or execution submission.

Core Rule

Common prompt should be short. Storyboard panels should be detailed.
