gsp-brand-brief

Works two ways:

1. Routed — /gsp-start detects "new brand" intent and invokes this skill
2. Direct — user runs /gsp-brand-brief directly

This skill handles new brands only. For existing brands (evolve mode), /gsp-start routes to /gsp-brand-audit directly.

Input: Brand name (from args or asked) Output: .design/branding/{name}/ with BRIEF.md, STATE.md, config.json, ROADMAP.md Next: /gsp-brand-research

<questioning_principles> One decision per question. Every question must be its own AskUserQuestion call. Ask one thing, wait for the answer, use it to inform the next question.

Never re-ask what the user already answered. If you need to validate, confirm: "I see X from earlier — still accurate?"

Inference over interrogation. Don't ask what you can infer. "Fintech for Gen Z" → mobile-first, modern, trustworthy. State inferences, let them correct.

Concrete options over open-ended. "More like Stripe's clean approach or Duolingo's playful style?" beats "What style do you want?" Use AskUserQuestion with 2-3 options when the option space is known.

Adapt and skip. If an early answer reveals enough, skip later questions. Follow up on surprises before moving on. The sequence is a guide, not a script.

Know when you have enough. A brand brief is complete when you can answer:

• Who is this for and what do they need?
• What does the brand feel like?
• What are the hard constraints? </questioning_principles>

Check if a brand name was passed via invocation args. If not, ask:

1. Ask for brand name (kebab-case, e.g., "acme-corp") — AskUserQuestion

Validate: lowercase alphanumeric + hyphens only. Check .design/branding/{name}/ doesn't already exist. If it does, use AskUserQuestion: Overwrite / Pick a different name.

Accept an optional e2e flag from the invoking skill. Default to false.

Create directory structure:

mkdir -p .design/branding/{name}/{discover,strategy,identity,patterns}
