impeccable vs ui-ux-pro-max-skill
Two of the top projects in Skills, plugins and prompts, side by side: who leads on each score part and who each one suits, then setup, license, activity and what each review found.
impeccable
Design skill with 24 slash commands for AI coding agents' frontend output
ui-ux-pro-max-skill
Design-system skill for AI coding assistants, with searchable styles, palettes and fonts
Verdict
impeccable ranks higher, 96 to 93. Of the 4 score parts we measure for both, impeccable leads on 2, ui-ux-pro-max-skill on 1 and 1 is even.
- Adoptionui-ux-pro-max-skill leads by 2 points, 98 to 96: close to even.
- FreshnessEven at 100.
- Maintenanceimpeccable leads by 3 points, 96 to 93: close to even.
- Agent-readyimpeccable leads by 30 points, 85 to 55: a wide gap.
Pick impeccable if you are
Developers using AI coding agents who want better frontend design output
- Installs into many agents: Claude Code, Cursor, Codex, Gemini CLI, Copilot, Grok Build, Hermes and more
- 61 detector rules run in the CLI and browser extension with no LLM or API key
Pick ui-ux-pro-max-skill if you are
Developers using AI coding assistants who want consistent UI/UX output
- Installs into 20+ assistants via the uipro CLI, or as a Claude Code plugin
- Search script uses only the Python standard library and makes no network calls

impeccable
Impeccable installs a single `/impeccable` skill into coding agents such as Claude Code, Cursor, Codex CLI, Gemini CLI and GitHub Copilot. It adds 24 commands (audit, critique, polish, typeset, layout and others), a live browser variant mode, and 61 deterministic detector rules for common AI-generated design tells. `/impeccable init` writes a PRODUCT.md that later commands use as context.
Who it is for: Developers using AI coding agents who want better frontend design output
Strengths
- Installs into many agents: Claude Code, Cursor, Codex, Gemini CLI, Copilot, Grok Build, Hermes and more
- 61 detector rules run in the CLI and browser extension with no LLM or API key
- Edit hooks surface detector findings back to the agent on Claude Code, Copilot, Codex, Cursor and Grok
- Apache-2.0, with npx, git submodule, plugin and manual copy install options
Weaknesses
- Skill runs through a separate binary downloaded on first run into ~/.impeccable/bin/
- Design roll requests go to impeccable.style and telemetry is on unless you opt out
- Hooks need per-harness trust approval, and Hermes and Veto get no edit hook
- Writes many working files under .impeccable/ that need a manual .gitignore block
- no GPU
- Needs Node.js (only for the npx installer), An AI coding tool such as Claude Code, Cursor or Codex CLI, impeccable.style roll API (telemetry can be disabled)
ui-ux-pro-max-skill
Installs as a skill or plugin for coding assistants such as Claude Code, Cursor, Windsurf, Codex CLI and Gemini CLI. A Python script using BM25 search and 192 reasoning rules returns a design system for a given product type: landing pattern, style, colors, typography, effects, anti-patterns and a pre-delivery checklist. The data covers 79 UI styles (50 active), 192 palettes, 74 font pairings and guidelines for 22 stacks.
Who it is for: Developers using AI coding assistants who want consistent UI/UX output
Strengths
- Installs into 20+ assistants via the uipro CLI, or as a Claude Code plugin
- Search script uses only the Python standard library and makes no network calls
- Output includes anti-patterns and an accessibility-oriented checklist, not only palettes and fonts
- Covers 22 stacks, from React and Vue to SwiftUI, Flutter and WPF
Weaknesses
- Requires Python 3 on the machine to run the search script
- Brand identity, logo and asset generation are in the paid premium version only
- Only 50 of 79 styles are active in default recommendations
- Output quality depends on the host assistant following the skill; no tests or benchmarks stated
- no GPU
- Needs Python 3, Node.js and npm (for the uipro CLI)
