## Best for

Frontend developers whose agents ship working UI that still looks generic or inconsistent.

## Why it deserves attention

Impeccable installs into Codex CLI, Claude Code, GitHub Copilot, Cursor, Gemini CLI, OpenCode, and other agents, then adds commands such as /polish, /bolder, /critique, and /audit that steer typography, spacing, hierarchy, and color against a rule set built to catch AI-generated interface clichés. It is Apache-2.0 with more than 100,000 GitHub stars and ships docs, examples, and a Slop gallery of before-and-after screens. It is opinionated and depends on the agent actually following instructions, so treat its output as a strong first pass rather than final design review.
