# Mental models framework built with agents

A solo founder gave Claude, ChatGPT, Windsurf, and Cursor defined roles to build and deploy a 120-model mental models framework.

Result: The author shipped 120 models, an MCP server for Claude Desktop, and 140 chaos tests with a 100% pass rate over 22 months.

## How it was set up

Four AI tools given defined roles with a SITREP coordination protocol, running four tasks in parallel. Stack: React, Cloudflare Workers, D1, TypeScript.

## Worth knowing

The 9.2/10 quality score is self-reported. The project took 22 months, and the agents' share of the work is not broken out.

## Evidence note

Author's own case study in a repo, plus live site and npm package; self-reported metrics
