An agentic skills framework & software development methodology that works.
Design judgment skill for agent builders
Impeccable Lite is a single-agent skill for frontend design work. It keeps the judgment layer from Impeccable and leaves out plugins, hooks, CLI tooling, live editing, and release machinery. It is meant to be copied into a skills folder or into project instructions when an agent does not support skills.
Builders who want their coding agent to make cleaner UI decisions and avoid generic interface patterns.
You can steer your agent toward more coherent, accessible, and intentional UI work without adding a full plugin system.
What it does
Design modes
Covers marketing pages, product UI, editorial work, and showcase-style interfaces.
Visual judgment guidance
Gives direction for typography, color, layout, interaction, and motion choices.
Anti-generic UI guardrails
Pushes back on the usual AI-generated interface patterns.
Accessibility and responsiveness
Includes requirements for accessible behavior, responsive layouts, performance, and edge cases.
Bounded workflow
Keeps the build and verification loop narrow instead of adding live editing or detector tooling.

Impeccable Lite
One skill. No plugin, hooks, CLI, or live mode. Just design judgment.
Impeccable Lite is a distilled, independent derivative of Impeccable. It keeps the frontend design guidance and removes the surrounding product ecosystem.
Why this exists
The original Impeccable combines design guidance with commands, deterministic detectors, lifecycle hooks, live browser editing, provider adapters, subagents, installers, and release tooling.
This feature set can be useful, but it can also feel bloated when all you want is better interface decisions.
Impeccable Lite keeps the judgment layer:
- strong, coherent visual direction
- design modes for marketing, product UI, editorial work, and showcases
- practical typography, color, layout, interaction, and motion guidance
- resistance to generic AI-generated interface patterns
- accessibility, responsive behavior, performance, and edge-case requirements
- a bounded build and verification workflow
If you need deterministic design linting or live browser editing, use full Impeccable.
Install
- Choose a skills directory from the table below.
- Create an
impeccable-litefolder inside it. - Save SKILL.md in that folder.
| Platform | Project | Personal or global |
|---|---|---|
| Claude Code | .claude/skills | ~/.claude/skills |
| Codex | .agents/skills | ~/.agents/skills |
| Cursor | .cursor/skills | ~/.cursor/skills |
| Gemini CLI | .gemini/skills | ~/.gemini/skills |
| GitHub Copilot | .github/skills | ~/.copilot/skills |
| Kiro | .kiro/skills | ~/.kiro/skills |
| OpenCode | .opencode/skills | ~/.config/opencode/skills |
| Pi | .pi/skills | ~/.pi/agent/skills |
| Qoder | .qoder/skills | ~/.qoder/skills |
| Rovo Dev | .rovodev/skills | ~/.rovodev/skills |
| Mistral Vibe | .vibe/skills | ~/.vibe/skills |
| Grok Build | .grok/skills | ~/.grok/skills |
| Antigravity IDE | .agents/skills | ~/.gemini/config/skills |
| Antigravity CLI | .agents/skills | ~/.gemini/antigravity-cli/skills |
| Trae International | .trae/skills | ~/.trae/skills |
| Trae China | .trae-cn/skills | ~/.trae-cn/skills |
Several platforms also recognize .agents/skills as a compatibility path. The table uses each platform's native directory so the installation does not depend on an alias.
Load the skill
Start a new agent session after installation. Codex can select the skill automatically for frontend design work or be invoked explicitly with $impeccable-lite. Claude Code notices changes inside existing skill directories automatically, but should be restarted if the top-level skills directory was created during the session. Gemini CLI can reload with /skills reload, Pi with /reload, and Qoder requires a restart.
If an agent does not support Agent Skills, copy the contents of SKILL.md into its project instructions. That fallback makes the design guidance always-on instead of loading it only for relevant UI work.
