Canvas Design

Audit web applications for WCAG accessibility compliance. Use when asked to run accessibility checks, identify common violations, and provide remediation guidance.

Intelligent interaction performance analysis with automated workflows for INP debugging, scroll jank investigation, and main thread blocking. Includes decision trees that automatically run script attribution when long frames detected, break down input latency phases, and correlate layout shifts with interactions. Features workflows for complete interaction audit, third-party script impact analysis, and animation performance debugging. Cross-skill integration with Core Web Vitals (INP/CLS correlation) and Loading (script execution analysis). Use when the user asks about slow interactions, janky scrolling, unresponsive pages, or INP optimization. Compatible with Chrome DevTools MCP.

Designer role. Reads deck.md, generates a single HTML presentation file with CSS design system + JS slide engine + per-slide content. Accepts visual references (URLs, screenshots, design specs) and extracts design signals to inform the isomorphic mapping. Use whenever the user says "design slides", "generate deck", "generate the deck", "build slides", "visual style", "reference this style", "like this design", "design", "generate slides", "visual style", "reference this style", or wants to turn an outline into actual slides.

UX research and design toolkit covering persona generation, journey mapping, usability testing, and research synthesis. Use for user research, persona creation, journey mapping, or design validation.

Produce a single-file slide deck in the Atelier Zero visual language (warm-paper background, italic-serif emphasis spans, coral terminating dots, surreal collage plates) — Open Design's brand deck recipe. The deck uses **horizontal magazine-style swipe pagination** (←/→, wheel, swipe), a per-slide chrome strip with brand mark and slide counter, an ESC overview grid, a coral progress bar, and inherits the canonical stylesheet + 16-slot image library from the sister `open-design-landing` skill.

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".
