Andreessen — Market-First Decision & Productivity Mode
Andreessen is a market-first decision and productivity skill that makes Claude operate like Marc Andreessen pressure-testing a pitch. It evaluates ventures, features, and career bets through Andreessen's frameworks—market dominates team and product, product/market fit is the only milestone, and bias to build—and delivers blunt, confidence-leveled verdicts. It also provides the 3x5 card + Anti-Todo personal productivity routine.
✨ What it does
- Runs a fixed anti-sycophancy operating prompt: leads with the strongest counterargument, never validates premises, uses
- Market-first evaluation with weighted scoring (market > team > product) and a hard kill gate for weak markets.
- Product/market fit signal scoring using the Sean Ellis 40% gate plus qualitative signals.
- Forcing-question interrogation (6 questions) before issuing a verdict.
- 3x5 card + Anti-Todo daily productivity system with a 3-5 must-do cap.
- Delivers verdicts: BUILD-POUR-FUEL, MARKET-FIRST-DERISK, or KILL-OR-REPICK-MARKET.
🎯 When to use it
- When you want a no-hedging, market-first verdict on whether an idea, venture, or feature is worth pursuing.
- When you need to check if you're at product/market fit (PMF) or want a PMF signal score.
- When you want to pressure-test a business idea or get a brutal, counterargument-first assessment.
- When you need a daily planning routine using the 3x5 card and Anti-Todo list.
🚀 How to use
Trigger the skill by saying 'andreessen', 'pmarca mode', 'should I build this', 'is there a market', 'pmf check', 'pressure-test this idea', or similar. It expects a description of the venture, idea, or feature, or a request for daily planning. For substantive bets, it will walk through forcing questions one at a time. Example prompts:
andreessen, should I build a new social media app for pet owners?
pmf check: we have 2000 users, 30% weekly retention, and some organic growth.
Plan my day with the 3x5 card.
📄 Output: A verdict (BUILD/DERISK/KILL) with confidence level, or a 3x5 card + Anti-Todo list for daily planning.

This skill is not for polite brainstorming; it is designed to be blunt and may deliver negative verdicts. It requires the user to engage with the forcing questions and provide honest answers.
❓ FAQ
What does the skill do if the market is weak?
A weak market is a hard kill gate—the verdict will be KILL-OR-REPICK-MARKET regardless of team or product strength.
How does the skill handle Andreessen quotes?
Every quote or date carries a confidence level (high/moderate/low/unknown), and it never invents citations; 'unknown' is acceptable.
Can I use the 3x5 card for daily planning?
Yes, the skill provides a 3x5 card system with a front capped at 3-5 must-dos and a back for the Anti-Todo accomplishment log.
