Memory from the coding sessions already on this machine — Claude Code, Codex, Cursor, Hermes and the other agents deja reads, including history from before it was installed. No model, no API key, no server.

## Good to know before installing

Runs the separately installed, unpinned deja binary (brew install deja-vu) as a subprocess; deja reads Claude Code, Codex, Cursor, Hermes and other agents' local transcript files, keeps its index under ~/.cache/deja, and recalled text from those agents is injected into Hermes turns; nothing leaves the machine.

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 deja-memory
```

2. Said no? Turn it on later:

```bash
hermes plugins enable deja-memory
```

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
