Covers websites, landing pages, dashboards, product UI, app shells, components, forms, settings, onboarding, and empty states. Handles UX review, visual hierarchy, information architecture, cognitive load, accessibility, performance, responsive behavior, theming, anti-patterns, typography, fonts, spacing, layout, alignment, color, motion, micro-interactions, UX copy, error states, edge cases, i18n, and reusable design systems or tokens. Also use for bland designs that need to become bolder or more delightful, loud designs that should become quieter, live browser iteration on UI elements, or ambitious visual effects that should feel technically extraordinary. Not for backend-only or non-UI tasks." license: Apache 2.0. Based on Anthropic's frontend-design skill. See impeccable/NOTICE.md for attribution.

Impeccable

This file is the top-level entry point so the skill auto-discovers via the standard SKILL.md convention. The canonical skill body lives at skill/SKILL.md (frontmatter + design laws + the 23-command router table).

How to invoke

The factory's pipeline agents (sop-qa-agent, design-fidelity-qa-agent, 14-template-builder, 09-build, 11-uplift) reference impeccable via specific reference files under skill/reference/:

• skill/reference/audit.md, the 5-dimension audit framework (a11y,

performance, theming, responsive, anti-patterns)

• skill/reference/critique.md, design critique methodology
• skill/reference/polish.md, surface-polishing commands
• skill/reference/harden.md, accessibility + hardening standards
• skill/reference/ux-writing.md, UI copy quality standards
• skill/reference/typography.md, typography rules
• skill/reference/color-and-contrast.md, palette + WCAG contrast

Plus 16+ other per-command reference files at skill/reference/.

The skill carries 23 user-invocable commands (/impeccable audit, /impeccable polish, /impeccable critique, etc.). Each command's reference loads on demand.

Where the project-level overrides live

CLAUDE.md in this directory carries the repo's project-level instructions for impeccable (post-update-cleanup overrides, register defaults, etc.). Treat CLAUDE.md as the local override layer; skill/SKILL.md is the upstream canonical source.

Factory pipeline integration

Read the specific reference file the stage needs, not the whole skill, to keep the context budget tight.
