Baseline immediately proposed a 10-feature roadmap (time tracking, multi-currency, mobile app, tech stack) for a freelancer-invoicing idea with no target user narrowed down; the skill version forced 8 sequential questions and produced a brief that explicitly excludes all of that scope creep and defers stack choice to a later pipeline stage, matching its own 'do not add features beyond the stated goal' quality bar.

What MVP Idea Brief does

Asks eight sequential clarifying questions -- target user, pain, current workaround, smallest useful outcome, platform, exclusions, budget -- then writes docs/IdeaBrief-[AppName].md. Triggers when a user has a vague app idea and needs scope narrowed before PRD or research work; the skill explicitly forbids adding features beyond the user's stated goal.
