OUR TAKE
Pick Impeccable for front-end developers and designers who let an agent write UI and want a review and polish pass built in. The hook runs outside model approval. In Claude Code, installed command hooks run even when the model's own commands are denied, and the first edit can download the engine binary. Review the hook before unattended runs.

Watch out
The hook runs outside model approval. In Claude Code, installed command hooks run even when the model's own commands are denied, and the first edit can download the engine binary. Review the hook before unattended runs.
Instead, try
Anthropic Frontend Design if you want only the short official brief Impeccable started from, in one SKILL.md file; Taste Skill if you want art direction and a browser pass for a distinct look, more than an audit

The hook runs outside model approval. In Claude Code, installed command hooks run even when the model's own commands are denied, and the first edit can download the engine binary. Review the hook before unattended runs.
- 02
Source files get pattern rules only. Contrast and tiny-text rules need a rendered page, so point detect at a dev-server URL for those.
- 03
A new design fetches visual directions from impeccable.style. Per the README's Telemetry note, turning telemetry off (npx impeccable telemetry off, DO_NOT_TRACK=1, or "telemetry": false in .impeccable/config.json) stops the anonymous record of which directions were shown and picked, not the fetch itself. Project name, files, code and PRODUCT.md are never sent.
- 04
It is a large skill. 24 commands and reference files are more to learn than a single-file brief.
