1# Creative Brief Selector
2 
3A starting-point selector for brand and microsite builds. Given a business spec (name, vertical, shape, one-line vibe, optional list of shipped demos), produces a creative brief grounded in three things:
4 
51. An archetype position from `brand-archetype-system`, picked or composed to be deliberately distinct from the shipped demos.
62. A small set of live reference sites for that archetype-and-vertical combination, drawn from a curated bank plus optional per-build discovery.
73. A divergence check against the shipped demos that flags palette, voice, structural pattern, and section-shape overlap before the brief is handed off.
8 
9The brief output is concrete tokens, not abstract families, including explicit section-shape choices (hero shape and footer shape) as first-class outputs alongside palette and voice. It is meant to be loaded by downstream build skills as the single creative artifact for the build.

13## When to use
14 
15- Starting any new brand or microsite build that should land in a specific aesthetic position.
16- The first build in a portfolio (no prior builds to diverge from yet, but the divergence schema can be seeded for the next one).
17- The second through nth build in a portfolio, where the risk of sibling output is real.
18- After a portfolio audit that surfaced sibling builds: this skill is the systemic fix for the pattern.
