Three Man Team

AI tools are powerful. And undisciplined.

AI coding tools are powerful but undisciplined. They read entire codebases when they need one function. They add features nobody asked for. They drift mid-task. They burn tokens on every session doing work that didn’t need to happen.

“The solution isn’t a better prompt. It’s a process.”

Three Man Team gives you three agents with distinct jobs, clear handoffs, and rules that prevent the most expensive failure modes. The Architect plans and deploys. The Builder builds exactly what the brief says. The Reviewer doesn’t pass work that isn’t right.

Why Three Agents

Three is not arbitrary. Solo agents drift — there’s no one to catch a wrong turn. Large teams generate coordination overhead that eats the productivity gain. Three is the minimum for meaningful review and the maximum before the team starts managing itself instead of the work.

The roles map to how real software ships:

• Someone who understands the whole system and owns the deploy
• Someone who builds fast and clean
• Someone who catches what the builder missed

The Workflow

Every unit of work follows the same path. Architect plans and writes the brief. Builder reads it, shows a plan, builds, and hands off to Reviewer. Reviewer clears it or sends it back. Architect deploys with the Project Owner’s go-ahead. Nothing skips a step.

The Team

Three agents. Three distinct jobs. Built to work together.

Architect, Builder, Reviewer are the defaults. Rename them to anything. Arch will handle it during setup.
