The quality claim comes from the developer alone

The agent checks its own output before returning it, rather than recreating an interface from a text description alone.
01
Generate
Agent builds the UI output
→
02
Record
Output is captured as footage
→
03
Examine
Agent reviews the footage for problems
→
04
Fix
Problems are corrected before return
Developer's claim
Self-review produces better results than prompting without the skill
Starter kit and example projects offer working templates
Built in React to fit common front-end workflows
Open questions
How well the self-check handles complex or highly customized designs
How much compute and time the loop costs
How reliably an agent can judge its own footage
Availability, licensing and pricing were not disclosed
