Stop pasting context. Point agents at the brain.

ReadmeDB is the shared markdown brain your agents read and update — across Cursor, Claude Code, and Windsurf. Not another chat memory. Versioned files your tools keep writing so you never spend ten minutes re-explaining the repo.

Why “memory” products miss it

Vector memory and chat summaries help one agent in one session. They don’t give Cursor and Claude the same durable project truth — decisions, open tasks, preferences — that both can edit.

Local CLAUDE.md / Cursor rules help on one machine. Switch tools or machines and you’re pasting again.

What a project brain looks like

• decisions.md — why we chose Postgres, not “ask me again”
• open-tasks.md — what the last agent left unfinished
• preferences.md — style, stack, “never touch X”
• team notes — shared namespace so every agent sees the same files
