Interface design, critique and quality checks for AI coding agents.
Impeccable helps AI coding agents design and improve websites, applications and other interfaces. Its commands cover UI planning, UX critique, technical audits, polish, responsive adaptation and design-system documentation. It also provides deterministic design checks and live browser iteration for local development.
Invoke impeccable with a target: for example, ask for audit to check quality, critique to review the experience, or polish for a final design pass. init gathers product context in PRODUCT.md; document records a DESIGN.md. Live mode is for local projects and should not be injected into deployed websites.
On first use, the launcher may download and verify a pinned upstream engine, requiring network access. Some features contact upstream services and may send telemetry; set DO_NOT_TRACK=1 or use the upstream configuration to disable telemetry. The Windows launcher was verified; other platforms and live browser iteration were not verified.
