Building a Shared Brain for My AI Agents — and Everything That Broke Along the Way

Meet Passport 🧳 — a shared memory layer for your AI coding agents.

I have three AI coding agents open right now. Claude Code in one terminal, Cursor in a window, Codex in another. And every single one of them is an amnesiac.

I'll spend ten minutes explaining my stack to Claude Code — we use pytest, the DB is Postgres, auth is JWT, don't touch the legacy billing module. It nails the task. Then I switch to Cursor for something else, and I'm back to square one. Same explanation. Different tool. Blank stare. By the third time I typed "we use pytest, not unittest" into a fresh chat, something in me snapped.

These tools are brilliant.

They're also goldfish.
