Build and test interfaces beyond the happy path.
What it does
Designs, builds, and audits user interfaces, providing implemented UI or evidence-backed findings and fixes.
When to use it
Use for building UI, documenting existing design systems, improving responsiveness or dark mode, auditing components, and testing worst-case data.
How to use it
Give it a UI request and a project; it builds or updates the interface, or returns findings when the request asks for review only.
What you provide
- An existing project
