BetterDB long-term memory provider — semantic recall on Valkey / valkey-search via the betterdb-agent-memory SDK. Completed turns are embedded and stored in a vector index; the next turn recalls the most relevant memories with a composite similarity/recency/importance score. Explicit betterdb_remember / betterdb_recall / betterdb_forget tools.

## Good to know before installing

Turn text and tool-stored facts are embedded through an OpenAI-compatible embeddings endpoint you configure (embeddings_base_url, default api.openai.com) and written to the Valkey instance you point it at; plaintext http:// to a remote host is refused. Opt-in, off by default: a discovery marker (set discovery=true to let BetterDB Monitor enumerate the tier) and SDK usage analytics (set telemetry=true).

From the plugin's catalog listing.

## 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 betterdb
```

2. Said no? Turn it on later:

```bash
hermes plugins enable betterdb
```

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
