What is it?

Every model was trained on the same SaaS templates, so you get the same tells on every project: Inter for everything, purple-to-blue gradients, cards nested in cards. Impeccable grew out of Anthropic's frontend-design skill and goes much further.

It gives Claude a shared design vocabulary through 24 commands such as polish, audit, critique, animate, bolder and quieter, plus 61 detector rules that catch generic design without needing an AI at all. A browser extension lets you iterate on the live page.

The /impeccable init step writes a PRODUCT.md that records your audience, purpose and voice, so later commands make decisions that fit your product instead of a generic one.

Install in Claude Code

From your project folder run npx impeccable install, then inside Claude Code run /impeccable init to record what the product is and who it is for. Alternatively run /plugin marketplace add pbakaus/impeccable and pick Impeccable from /plugin.
