<!-- 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. Run the spec-driven design pipeline for `$ARGUMENTS`. Load the `ui-craft` skill. --- ## ORCHESTRATE-ONLY RULE This command **sequences existing phase commands**. It MUST NOT re-implement or duplicate any logic from them. Every composition rule, wireframe algorithm, craft rule, and convergence engine lives in the phase commands. This command contributes only: 1. Gate detection (does the artifact exist?) 2. Offer prompts (run phase X or skip?) 3. Progress reporting (the checklist) 4. Degraded-mode honesty (what was skipped and what that costs) When in doubt: call the phase command, don't inline its steps. --- ## Progress Checklist Print this at the start and update it after each gate resolves: ``` [ ] brief [ ] tokens [ ] shape (spec) [ ] craft (build) [ ] converge [ ] ship ``` Use `[✓]` for completed/skipped-with-artifact, `[>]` for the current gate, `[–]` for skipped-without-artifact (degraded). --- ## Pipeline Gates ### Gate 1 — Brief Check: does `.ui-craft/brief.md` exist? **If yes:** mark `[✓] brief`. Note that brief §6 learned constraints and the a11y/correctness floo...
