VercelChecks a build against the published guidelines rather than a reviewer's taste, covering accessibility, interaction and the details that guidelines exist to settle.
In the author’s words
Review UI code for Web Interface Guidelines compliance. Use when asked to "review my UI", "check accessibility", "audit design", "review UX", or "check my site against best practices".

Goes well with
emil-design-eng
The design-engineering house style behind Sonner and Vaul.
Emil's main skill. Mostly animation, with the UI-polish and component judgement that surrounds it: what to build, how far to push it, and when to stop.

review-animations
Reviews your motion strictly, against Emil's rules.
A production-critical pass over animation quality, timing and consistency in a diff. Pairs with improve-animations, which does the same for a whole codebase.

improve-animations
Audits every animation in a codebase and hands back prioritised plans.
Read-only on source. Surveys the motion you already ship and produces self-contained implementation plans any agent can execute, ordered by what actually matters.
