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.

Load references/brief.md for the brief format before proceeding.

Step 1: Detect existing brief

Check whether .ui-craft/brief.md exists. Use Read or ls on .ui-craft/.

If it exists: load its contents. If $ARGUMENTS names a specific update ("update principles", "shift target user", "add out of scope"), focus the session there and skip unchanged sections. Otherwise summarize what's in the brief and ask: "What do you want to change?"

If it doesn't exist: proceed to Step 2. Also check the repo root for a DESIGN.md or design-tokens.json (an ecosystem convention some teams already maintain) — if present, read it and pre-fill the brief's answers from it instead of re-asking; note the source. The brief complements an existing design contract, never contradicts it.

Step 2: Draft a new brief (absent case)

Walk the user through the five required sections in a single pass. Ask ONE compact question per section. Do not open five separate prompts unless the user asks for depth.
