A prompt to start from
Use Tesseract. Create an eight-second silent Tesseract mask-expansion study. Reveal moving water footage through a fixed 500 px circular guide at right of a Cloud canvas. Grow the actual path-mask expansion from 0 to 105 px over 3.4 seconds, beginning at 0.8 seconds; never scale or rewrite the guide geometry. At left use Exposure[-30] “Make / room.” and two small Denim lines “One guide. / More room.” Keep the center and media fixed so the expanded visible area is unmistakable. Demonstrate positive growth only; negative shrink is unsupported in the installed renderer.

How do I try this with my agent?
Copy the prompt into your supported local agent with Tesseract installed. Review the preview, then ask for the changes you want. The composition stays editable as you refine it.
Where does the video render?
Tesseract previews and renders locally on macOS, Windows, or Linux. The local engine is free; your agent’s subscription or usage costs are separate.

Set up Tesseract by Mirage so you can create editable designs, edit videos, and make motion graphics in this agent’s environment. Read https://github.com/mirage-hq/Tesseract and check the requirements for this local or hosted environment. If it is supported, follow the official plugin or skills installation guide, use its required runtime version, verify the download checksum, and confirm a short preview renders correctly. Then ask what I want to make and which brand references or source assets I have. Keep the editable project and source assets with the finished render.
