skill-concept
A composable skill for generating concept variations. /mb-site calls this after the brief is locked, before the first publish.
Inputs
The locked brief (path provided in the user message)
N localhost-runnable HTML variations, each in its own subdir of the project repo (e.g., concepts/v1/, concepts/v2/)
A short comparison summary for the operator: hero artifact, palette, voice variant for each
Operator picks one; that variation is promoted to the project root
Flow
Spawn N foreground subagents (default 2). Each gets the same brief + reference URLs but is asked to make different decisions.
Each subagent writes its variation. Foreground only — background writes are known to silently fail.
Validate each variation: footer present, OG.svg under 1200×630, no AI tells in the copy.
Render preview.python3 -m http.server from each subdir; open in browser.
Operator picks. One concept → promoted to repo root; others archived under concepts/.
Foreground rule
Subagents MUST be foreground. The known background-subagent file-write bug means files appear written but don't persist. Foreground only. See references/concept-variations.md for the spawn pattern.
