What Impeccable provides
Agent design commands
Slash flows such as polish, typeset, distill, audit, harden, onboard, and live mode steer the agent through concrete design jobs.
AI-slop detector
Dozens of checks flag defaults agents overuse—beige palettes, competing hierarchy, status-chip soup—and can run without an extra model API key.
DESIGN.md & PRODUCT.md
Document visual rules and user goals once so later features stay on-brand and task-focused.
Respects your system
Reads tokens, Tailwind theme, and component libraries so new screens feel like the same product.
Multi-tool installers
npx impeccable install, Claude Code marketplace plugin, skills.sh, and Copilot experimental paths—each build tailored to the tool.
Chrome & CI extras
Optional Chrome DevTools panel and CLI checks for PRs so findings can gate builds.
How to use Impeccable
Install for your coding tool
Run npx impeccable install, add the Claude Code marketplace plugin, or enable the Copilot path—match the installer to your agent.
Initialize project context
Run /impeccable init (or document/extract) so DESIGN.md and PRODUCT.md capture brand rules and users.
Describe the change
Ask for polish, typeset, distill, or a full page build while keeping existing corners, palette, and components.
Run the detector
Review AI-slop findings, fix P0 issues first, then re-check until findings clear.
Optional live mode
Point Live Mode at localhost, pick elements, and steer page-level refinements against production source.
Who Impeccable is for
Claude Code & Cursor users

Indie makers killing vibe-coded UI
Need a structured pass to remove AI tells before customer-facing launch pages.
Teams with an existing design system
