Local Markdown memory provider with multilingual lexical recall and profile-local durable notes. Create-only writes are limited to primary agent contexts. Uses published birkin-mnemosyne 0.7.2 with compatible updates below 1.0; no API key, network service or telemetry. Session handoff capture is opt-in. Native Hermes memory files remain separate.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install birkin-mnemosyne
```

2. Said no? Turn it on later:

```bash
hermes plugins enable birkin-mnemosyne
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
