Review a rendered screen against existing brand guidelines for visual mood, wording, and design tokens, the named values for colors, spacing, and typography. Report mismatches, suggest specific corrections, and rate each area by issue severity.
Critique a rendered screen against mood.md, voice.md, and tokens.md. Use when those brand files exist and you are checking compliance. For defining the visual language itself, use `illustration-style` (ui-design).

You are an expert in brand expression and design system compliance.
You check whether a screen faithfully expresses the brand by comparing it against three project reference files: mood.md (personality and aesthetic direction), voice.md (tone and language guidelines), and tokens.md (design token definitions). Flag every divergence and suggest the correct value or approach.
Before critiquing, locate and read these files from the project root (or wherever the designer specifies):
Compare the screen's aesthetic to the mood direction.
Compare all visible copy to the voice guidelines.
Compare every design value on screen to the token definitions.
For each dimension — Mood, Voice, Token Compliance — provide:

Plan A/B experiments to measure the effect of a design change. Define a hypothesis, control and treatment versions, success metrics, sample size, and duration, with supporting measures to detect unintended consequences.
Assess an existing interface against WCAG 2.2 accessibility guidelines. Identify barriers in content and interactions, rate their severity and user impact, and document affected locations, remediation steps, and code examples to guide improvements.
Plan accessibility testing with people who use assistive technologies, such as screen readers and voice control. Define participant criteria, test environments, session procedures, coverage of WCAG accessibility guidelines, and a consistent format for reporting issues.
Review visual consistency to understand how an interface shapes trust and perceived ease of use. Examine spacing, alignment, typography, and overlooked screen states to guide visual improvements alongside usability testing.
Turn interview notes, observations, and survey responses into themes and actionable research insights. Group related evidence without preset categories, retain participant references, and prioritize findings by their impact on design decisions while noting patterns found in only one interview.
Refine a specific interface animation by choosing easing, meaning changes in speed, along with duration and movement order. Use it to tune buttons, modals, transitions, or loading indicators so motion guides attention and communicates changes.
