Impeccable
Impeccable gives coding agents persistent product/design context, a shared design vocabulary, and deterministic anti-slop checks instead of relying on one giant aesthetic prompt.
Routing Summary
Start with Kevin's installed routes: taste, design-engineering-polish, frontend-design, and web-design-engineer. Use Impeccable when a project would benefit from its PRODUCT.md / DESIGN.md setup, command vocabulary, browser/live iteration, or deterministic detector layer. It is currently a reviewed external source, not a silently installed global default. Source: Impeccable README, reviewed 2026-07-14
Why It Matters
Impeccable turns “make it look better” into named operations such as shape, critique, audit, polish, bolder, quieter, distill, harden, animate, typeset, and layout. Its initialization flow records audience, product/brand lane, voice, anti-references, colors, type, and components so later agent passes share the same design model. The project also advertises 46 deterministic detector rules alongside LLM critique checks. Source: Impeccable README, reviewed 2026-07-14
Adoption Boundary
| Situation | Route |
|---|---|
| One-off local polish | Existing Kevin design skills first |
| Project needs durable design context | Evaluate /impeccable init and generated design files |
| Repeatable anti-pattern enforcement | Evaluate deterministic detectors and hooks |
| Third-party install requested | Inspect source, run skill/security audit, then choose project-local before global |
