Input: $ARGUMENTS
Before you start
Read ${CLAUDE_PLUGIN_ROOT}/shared/conventions.md and follow it.
- Reads:
founder/facts.md,founder/validate-idea.md,founder/persona-gen.md,founder/competitor-matrix.md - Needs: the idea in one sentence
- Saves to:
founder/product-brief.md
Instructions
-
Problem statement. What specific pain does this solve? Who feels it most? How do they deal with it today?
-
Target audience. Name the primary audience in one specific sentence. Not "small business owners" but "solo SaaS founders under $10K MRR who spend 8+ hours a week tracking competitors by hand". If
founder/persona-gen.mdexists, use its primary persona. Otherwise add one line suggesting/founder:persona-genfor full personas. -
Value proposition. One sentence that passes the "so what?" test. Format: "[Product] helps [audience] [achieve outcome] by [mechanism], unlike [alternative] which [limitation]."
-
Core features (MVP). Exactly 5-7 features. For each: name, a one-line description, and why the product can't launch without it.
-
Success metrics. 3-5 measurable KPIs with targets for the first 90 days. Include leading indicators, not just revenue.
-
Risks and assumptions. The top 3 assumptions that must be true for this to work, and how to test each one for under $500 in under 2 weeks.
-
Go-to-market snapshot. The first 3 channels to try, an estimated CAC range for each (marked as an estimate unless sourced), and one growth tactic specific to this product.
Rules
- Be specific and opinionated. Generic advice is useless.
- Use numbers, not words like "some" or "many".
- If the idea is vague, make reasonable assumptions and state them.
- Output clean markdown with headers and bullets.
- Keep total output under 1500 words.
