/business-brainstorm — Pressure-test a business idea

Takes a vague idea, runs it through the user's filter, and outputs a structured viability brief. Composes with deep-research (for market) and /domain (for naming).

Step 1 — Capture the idea

Get from the user:

• The idea in 1–2 sentences (the what)
• The reason it's on their mind (the why now)
• Any starting context (a chat where this came up, a tweet that inspired it, a problem they've hit)

If they point at a past chat / doc, load it first. Memory has project_*.md files for in-flight projects — check there before assuming the idea is brand-new.

If the idea is too vague to score, ask 1–2 clarifying questions and stop. Don't pad the brief with assumptions.

Step 2 — Load the framework + personal overlay

Read references/framework.md — the user's filter. Apply each dimension in order.
