Impeccable skill vs UI UX Pro Max for coding agents

Frontend design skill, and Taste Skill for Claude Code

The Impeccable skill is the primary comparison. A detector result is not an accessibility or visual-quality proof. That limit is on the Impeccable record. UI UX Pro Max writes a per-project MASTER.md, which the record says is not a single published design system. On 2026-10-24 the README and the uupm.cc page disagreed on style, palette, and stack counts. Neither count was audited, so this page does not repeat the numbers.

Taste Skill is a separate MIT skill. Its documented clients are Claude Code and Codex. The README did not document Cursor. UI Skills names no clients.
