# Startup Design A structured, multi-phase skill that takes a startup idea from raw concept to validated design. It produces a complete set of markdown documents organized by domain, with built-in progress tracking so work survives session interruptions. ## How It Works The process has 8 phases executed sequentially. Each phase produces output files and updates the progress tracker. If a session is interrupted, resume from the last completed checkpoint. ``` INTAKE → BRAINSTORM → RESEARCH → STRATEGY → BRAND → PRODUCT → FINANCIAL → VALIDATION ``` ### Modes **Full Mode (default):** Execute all 8 phases in order. Best for thoroughly designing a startup from scratch. **Fast Track Mode:** When the user says they want a "quick validation," "rapid assessment," or similar, or when time/budget is clearly limited, run a compressed version: 1. Phase 1 (Intake) — shortened to 1 round of questions 2. Phase 2 (Brainstorm) — 3 variations instead of 5-8 3. Phase 3 (Research) — Wave 1 + Wave 2 only (skip customer voice and distribution deep-dives) 4. Phase 4 (Strategy) — Lean Canvas only 5. Skip Phase 5 (Brand) and Phase 6 (Product) 6. Phase 7 (Financial) — Revenue model only, no full projections 7. Phase 8 (Validation) — Scorecard + top 3 experiments only Fast Track produces fewer files but still gives the founder a clear go/no-go signal with evidence. Note in PROGRESS.md that Fast Track mode was used, so a future session can expand to full mode if the idea passes validation. ### Lan...
