Skill: Brainstorm Design

Purpose

Transform rough ideas into validated, production-grade designs through systematic collaborative dialogue. Prevent premature implementation by exploring context, clarifying requirements, proposing alternatives with trade-offs, and obtaining explicit approval before any code is written.

Core Objective

Primary Goal: Produce a validated design document that serves as the single source of truth for implementation.

Success Criteria (ALL must be met):

1. ✅ Design document exists: Written to docs/design-decisions/YYYY-MM-DD-<topic>.md and committed to version control
2. ✅ User explicitly approved: User said "approved", "looks good", "proceed", or equivalent confirmation
3. ✅ Alternatives documented: At least 2-3 approaches considered with trade-offs analysis
4. ✅ YAGNI applied: Design focuses on minimum viable solution, unnecessary features removed
5. ✅ DRY applied: Design references existing patterns/components rather than reinventing
