<!-- HARNESS MIRROR — do not edit here. Canonical source: skills/ or commands/. After editing source, copy into cli/assets/<harness>/ and repo-root harness mirrors. --> **Context:** this sub-skill is one lens of the broader `ui-craft` skill. If the `ui-craft` skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below. Polish the UI at `$ARGUMENTS`. Load the `ui-craft` skill. **Source of truth:** read `references/review.md` → **Polish Pass (Compound Details)** section. Apply every item on that list to the target. Do not re-derive the list here — `review.md` owns it. **Then the signature detail**: surfaces built via `/craft` already carry exactly one signature bet, chosen in the Craft Read and built in the first pass (`references/craft-intent.md`). Polish **verifies it survived and strengthens it** — never stacks a second. Only if the surface predates craft-intent (no signature anywhere) do you propose and add one: a subtle motif, an asymmetric layout break, a custom list marker, a distinctive hover — one thing someone would remember. **Knob gating (CRAFT_LEVEL):** - `≤ 4` → skip the Polish Pass. Ask the user first before running it. - `5-7` → apply everything on the list, leave the signature as-built unless asked. - `8+` → apply everything + verify/strengthen the signature detail (add one only if the surface has none). **Output**: edit the code directly (polish is implementation, not critique).
