Retia sits between your agents and your work as one shared, structured layer. Here's the whole loop — from the first connection to agents handing off work across projects.
Retia is an MCP server. Point Claude, Claude Code, Codex, or Cursor at it once — one token, one URL. From then on, every agent on every device shares the same vault. No per-session setup, no copy-pasting context between tools.
As your agents work, they record what matters: decisions, lessons, dead ends, open cases. Each note has a type, tags, and a sensitivity level — so the vault isn't a transcript, it's a structured body of knowledge. The handoff unit isn't a conversation. It's one distilled note.
When an agent starts, it doesn't begin blank. Retia hands it a dense, auto-generated summary of the project — the stack, the architecture, open decisions, what's done and what's not. One call, full context. The reminder you used to paste by hand is already there, current, and never stale.
When an agent needs something specific, it asks. Retia's librarian routes that intent to the right source and returns the precise note — and shows its reasoning. Not a vector black box you trust blindly. You can always see why a note was the right answer.
This is where a memory tool becomes a substrate. One agent opens a case and leaves a brief. A different agent — different vendor, different session, zero prior context — reads it, acts, and writes back. They verify each other's work and coordinate before a single line hits git. Git shows what changed. Retia shows who and why.
Reliability is built in: pre-flight checks before destructive operations, snapshot-before-change, append-only storage (nothing is hard-deleted), and a rule that no agent closes its own work — only the verifier can. A dead end discovered today is recorded, so it's never re-walked tomorrow. And an honest meter shows exactly what you saved, in real tokens at real price.
