Today, we’re open-sourcing the draft specification for DESIGN.md, so it can be used across any tool or platform. We’re also adding new capabilities.
DESIGN.md lets you easily export and import your design rules from project to project. Instead of guessing intent, agents know exactly what a color is for and can even validate their choices against WCAG accessibility rules.

🎭 Head tilts. Pauses. Cadences. Micro-expressions.
➡️ A single image → a video that feels real, not rendered.
Rolling out to all users now.
