impeccable
Design skills, commands and anti-pattern detection for AI coding agents. The design hook fires on direct edits to UI files and pushes its findings straight back into the agent's flow — not into a report you read afterwards. It ships `palette.mjs` (an OKLCH seed built from 129 curated colours) and `concept-seed.mjs`, which forces the agent away from its own favourite answer.

- Proof
- “59 deterministic detector rules for AI-generated frontend design” — README, read at the source on 31 July 2026.
- Can't do
- It only checks what someone wrote down as a rule. Whether the design direction is any good, it will not tell you — which is why it sits late in the stack, after the direction is set.
Playbook — how to actually use it
A skill without instructions is a download, not a capability. This is the part we wrote: what the commands do, which one to reach for, and how to phrase the request so it lands.
Or hand it straight to your agent
Drops the same guide next to the skill as PLAYBOOK.md — plain markdown, so the agent reads it along with the skill.
