Build a mental models framework with a multi-agent dev team with Claude
A solo founder used Claude, ChatGPT, Windsurf and Cursor as role-based team members to design, test and deploy a 120-model mental-models framework and MCP server.
Done with Cursor
What they did
A solo founder treated Claude, ChatGPT, Windsurf and Cursor as team members with defined roles, coordinated through a SITREP protocol and running four in parallel. They used the framework's own mental models to architect, validate and deploy it, with a 5-question wickedness rubric to set problem tiers. Stack: React, Cloudflare Workers, D1, TypeScript.
How it went
The result was 120 models with a 9.2/10 quality score, 140 chaos tests all passing, and an MCP server for Claude Desktop. The whole effort took 22 months.

Try it yourself with Cursor
Help me build a [number]-item framework of [mental models or other reference content] as structured files, plus a small MCP server that lets an AI look up entries by name or situation. Start with a data format, write [number] sample entries, then build the server and tests. Finished means I can query the server from my AI client and get a correct entry back. Ask before deploying anything publicly.
