impeccable

what it is

A design skill for coding agents, installed with npx skills add pbakaus/impeccable. It works in Claude Code, Cursor, Gemini CLI and Codex CLI. The thesis is “great design prompts require design language,” so it hands the agent designer vocabulary and named commands, which lets you ask for more than “make it better.” Licensed Apache 2.0.

Some of the commands:

• shape plans the UX before any code
• critique runs a UX review with heuristic scoring
• audit checks accessibility, performance and responsive behavior
• polish is the final pass before shipping
• harden covers error states, i18n and edge cases
• bolder, quieter and distill push a design louder, calmer or simpler
• animate adds purposeful motion

how I use it

Installed as a Claude Code skill (v4.1.1 when I wrote this). I call it as /impeccable <command> <target>.

what I found

• The April demo showed separate slash commands chained together, like /critique /harden checkout. The current version folds them into one skill with sub-commands.
• Before acting it loads project context from PRODUCT.md and DESIGN.md if they exist.

compared to

• Taste Skill covers the same category more broadly. Emil Kowalski Skill is animation only.
• gstack has its own /design-review and /design-shotgun.
