## What it is

Open source set of commands and rules that helps coding agents produce better interfaces and detect generic patterns of AI-made design.

## What it’s for

For reviewing and adjusting screens generated by agents: adding boldness, polishing typography, auditing accessibility or iterating live in the browser.

## Benefits

- 24 direction commands, such as bolder, quieter, polish and typeset
- critique gives a scored UX review; audit lists issues from P0 to P3
- 62 deterministic rules detect generic patterns, with no LLM or API key
- Live mode: select elements on the dev server, try variants and write the chosen one into the code

## Caveats

- Apache 2.0 license; the page doesn't state a price.
- The detector runs as a hook, a CLI (npx impeccable detect) or a Chrome extension.
