Mental Models OS
Cooking judgment into your second brain.
You reached out about the Mental Models OS. Here it is. Plus what to do next if you want more, or less.
The Mental Models OS
I've cooked every first principle and mental model I use into these files. My decision-making went up 10x.
80 mental models packaged as executable skills, plus 7 pre-built chains for the calls that come up most.
Type /think "[your hardest call right now]" and it picks the right 5 models, chains them in sequence, returns a decision brief with confidence level and where the models conflict.
- 11 categories: general thinking, systems, economics, business strategy, physics, psychology, startup, math, networks, learning, art
- 7 pre-built chains: pricing, hiring, market entry, "should i quit", product launch, investment, life decisions
- One command. No signup. Drop it in your terminal and go.
The world's most complete GTM x AI Second Brain
By the way, I've cooked the Mental Models OS into my Second Brain. The thinking layer plus everything else I run my business with.
Install it. Adapt it. Grow your company.
Not a chatbot. Not a prompt library. Not a fancy CLAUDE.md file. A ready-to-use GTM x AI operating system, packed with 100+ playbooks, 100+ automated skills, and 100+ agents that talk to each other.
Every playbook was extracted from real client work. Every skill was built because I needed it. Every framework was tested across multiple companies before it went in. This is my daily driver, and now it's yours.
Four layers compound. Playbooks give you the strategy. Agents do the work. Skills are the commands you type. Workflows chain them into pipelines.
- 100+ skills (positioning, ICP, competitor research, SEO, GEO content, outbound, sales enablement, analytics, voice calibration)
- 100+ playbooks for B2B and B2C, battle-tested in real client work, new ones drop every week
- 100+ agents running in parallel, with persistent memory that compounds session to session
- Connectors to your real tools: Notion, Slack, Stripe, PostHog, Google, Linear, more
