Durable memory and context compression for Hermes Agent with local SQLite or flat-file storage.

## Good to know before installing

Replaces the memory provider (memory.provider: nachos) and, only when context.engine: nachos is set, the context engine; the provider injects a system-prompt block telling the agent to use the nachos_memory_* tools and keep built-in memory disabled; opt-in semantic ranking either runs a separately installed nachos-embeddings CLI or sends the turn query plus memory titles/summaries to api.openai.com with OPENAI_API_KEY; all storage is local under $HERMES_HOME/nachos/.

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 nachos
```

2. Said no? Turn it on later:

```bash
hermes plugins enable nachos
```

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
