Birkin Mnemosyne: local Markdown memory with multilingual lexical recall. A Nodecode rewrite of ashmoonori-afk/birkin-mnemosyne by ashmoonori-afk.

Notes are ordinary Markdown files under this home. There is no service, no API key and no telemetry: the model writes a note, searches it by the words it shares with the vault, reads one back, and archives one it no longer needs. Nothing is deleted — archiving moves a note under _archive and restoring moves it back, previewed first.

Get it

Tell the agent "add the birkin cell", or run nodecode add nc://birkin.

Set it up

Nothing is required. /birkin shows the vault it is on. In /settings, or the birkin section of config.jsonc:

{
  "birkin": {
    "vault": null,          // a folder; a birkin folder under this home unless answered
    "max_results": 8,       // how many notes one search or the digest returns
    "prefetch": true        // put the newest notes on each turn's first request
  }
}

An existing Hermes vault can be pointed at with vault: the notes are the same Markdown with a title: frontmatter line, so a vault written by the original plugin is read as it stands.

Use it

Five tools, all exact:

• birkin_remember — title and body; an existing title is refused, never overwritten.
• birkin_search — query, optional limit (1 to 20) and labels (namespace:value, matched with AND). Lexical, in any script: a Korean or Chinese note is found by the words a query shares with it.
• birkin_get_note — title, the whole body.
• birkin_forget — note, an optional reason, and confirm; preview by default, and only confirm=true moves the file under _archive.
• birkin_restore — note, optional zone (default inbox), confirm; brings an archived note back unchanged.

/birkin with a query searches the vault, without one it shows where the vault is, how many notes it holds and how many are archived. With prefetch on, the newest notes ride the first request of each turn as a digest, framed as data, not instructions. The manual is (help :birkin).
