As AI coding becomes part of the design-to-code workflow, I think there is a new type of information that belongs in Figma:
Implementation annotations.
Today, annotations can only be added by people with edit access to the design file.
This works well for design explanations, but not for implementation guidance.
Imagine this workflow:
A designer finishes the UI.
Later, a developer reviews the design before implementation and notices several places where additional implementation context would help an AI coding agent generate much better code.
For example:
- This Frame should be implemented as a scrollable list.
- This component should use virtualization.
- This area should stay fixed while the content scrolls.
- This value comes from the current device model.
- This text should truncate after two lines.
- This image should preserve its aspect ratio.
- This section should use the shared DeviceCard component.
- This layout should become two columns on larger screens.
None of these change the visual design.
They are implementation details.
Today, the only options are:
- Ask the designer to add annotations.
- Write long prompts every time an AI coding agent is used.
- Maintain separate implementation documentation.
None of these scale well.
I think developers should be able to contribute implementation annotations without modifying the design itself.
These annotations could become part of the Figma MCP context, allowing AI coding agents to automatically understand implementation intent.
Instead of writing prompts like:
"Treat this Frame as a list. Read this value from the current device model. Keep this area sticky..."
the developer could annotate the relevant layers once inside Figma, and every future coding session would automatically inherit those instructions.
This would make AI-assisted implementation much more accurate while keeping implementation knowledge close to the design.
I imagine something like:
Implementation Annotation
- Editable by developers (Dev Mode or developer role)
- Attached to any layer
- Separate from visual design
- Included in Figma MCP responses
- Invisible during normal design work unless enabled
This would make Figma not only the source of truth for design, but also the source of truth for AI implementation.
