Give your coding agent real design judgment
A structured skill set that agents load to make typographic, layout, spacing, and color decisions with design intent rather than defaults.
Identifies recurring AI-generated UI clichés such as chip overload, card-in-card nesting, weak hierarchy, and vague calls to action.
Helps the agent stay consistent with the tokens, components, and conventions of your existing design system.
Bakes in contrast, focus, semantic structure, and responsive behavior so built interfaces hold up across devices and audiences.
The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.
Provides a full AI-native code editor experience, but requires manual prompt rules or extensions to enforce design discipline.
