Tastemaker gives coding agents a persistent design system before they generate UI
The author built Tastemaker, an open-source MIT-licensed skill for coding agents that aims to keep frontend output visually consistent across long sessions.
It saves project-level design decisions before the agent writes UI, including:
- design tokens and valid color combinations
- typography, hierarchy, layout, and spacing rules
- icon and illustration direction
- logo and favicon assets
- accessibility constraints
- motion and interaction behavior
It can also inspect a reference image, extract colors from pixels, validate contrast, and turn the results into reusable project tokens.
The key idea is persistence: instead of relying on a vague prompt remembered at the start of a chat, the agent can refer back to concrete files and rules throughout the project. The author asks for feedback on how to keep subjective visual choices stable across long agent workflows and what checks should run before a frontend task is considered done.
