Librarian: memory for your agents

Claude Code and Codex find past decisions themselves instead of starting every session from zero. Runs on your machine.

What is included

01The Librarian source code: the same memory pattern my own agents run on
02Claude Code and Codex log adapters that turn a finished session into a short factual digest
03PostgreSQL with pgvector for search by meaning, not just keywords
04Four MCP tools: search, digest, session list and “remember this” on your explicit request
05Docker Compose for macOS, Linux and your own server
06A synthetic end-to-end check that proves the install before any real logs are used

A ZIP archive with source code and documentation, all in English. Start with START_HERE.md: hand it to your agent and it installs Librarian step by step. The kit's own licence (LICENSE inside the archive) also applies.

A good fit if

You work in Claude Code or Codex every day, and every new session starts from zero: the agent rediscovers what you already decided yesterday. You want past decisions to surface on their own.

Not a fit if

If you do not work with terminal agents yet, start with a simpler step. This is not a hosted service or an app with buttons: it runs on your machine and needs Docker and a little patience.

How it works

1Download the archive and give START_HERE.md to your agent.
2Enter your own Gemini API key; the agent sets up the database and MCP.
3Pass the synthetic check, and only then connect your real sessions.

Good to know first

Requires Claude Code or Codex, plus Docker on your computer or server.
Digests and search use the Gemini API: you need your own Google key, and requests may cost money.
No automatic capture: sessions are ingested by command, and “remember this” runs only when you ask.
Runs locally or over an SSH tunnel. Never expose the server to the internet; there is no multi-user access and no backup.
Digests are model-generated and can miss details. Check important decisions against the original session.
Secret redaction is heuristic and cannot guarantee removal. Check what you ingest.
Licensed to one buyer or one company: no resale or publication.

Questions

Is this the same system you run?

The same pattern and the same memory core, without my personal extras such as the UI, graph or CRM. Only what agents need.

Does my data leave my machine?

The database stays with you. Session text and chunks are sent to the Gemini API under your own key. On the free tier Google may use them and show them to human reviewers, so use a paid project for work or confidential data. PRIVACY.md explains it in detail.

Can my company use it?

Yes. The licence lets one buyer or one company use and modify the kit for its own work, including commercial work.

What if it is not right for me?

Email me within 14 days for a refund. You do not need to explain why.
