## The Hook

Impeccable is a design skill + command set for AI coding harnesses: PRODUCT.md truth, 24 /impeccable commands, and 61 deterministic detectors so agents stop shipping Inter-and-purple defaults.

## What's Good

Apache-2.0 (pbakaus/impeccable). One skill covers craft/init/audit/polish and more; CLI and browser extension run deterministic rules with no LLM key. Installs into Claude Code, Cursor, Codex, Grok, Hermes, and peers via `npx impeccable install`; docs at impeccable.style.

## The Catch

Vs Superpowers and agent-skills packs: Impeccable is a design-language/skills layer for UI quality, not a coding agent and not a general agent-skills monorepo. Node ≥22.18 for the npx installer path; star count is extreme (~70k) — treat momentum as discovery noise until the skill actually changes your harness output.

## Verdict

Apache design skill when your coding agent ships samey SaaS UI and you want PRODUCT.md + detectors in-loop; not a substitute for an agent runtime.
