Self-owned long-term memory backed by the agent-memory-es service (Elasticsearch). Three agent tools — recall, retain, reflect — over episodic/ semantic/procedural tiers with hybrid BM25+kNN recall and server-enforced private/team/common visibility. Requires a running agent-memory-es instance.

## Good to know before installing

Each user prompt (as a recall query), each user message and Hermes memory writes are sent to the agent-memory-es service at AMES_SERVICE_URL (default localhost:8123) with AMES_SERVICE_KEY; the model may store facts in shared team/common visibility tiers.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `AMES_SERVICE_URL`, `AMES_SERVICE_KEY`), then asks whether to turn it on.

```bash
hermes plugins install agent_memory_es
```

2. Said no? Turn it on later:

```bash
hermes plugins enable agent_memory_es
```

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
