CortexLayer memory provider — page-linked long-term memory with link-expansion retrieval, wired into Hermes' automatic per-turn recall (prefetch) and persistence (sync_turn), plus a pre-compress checkpoint so evidence Hermes' own context compaction would otherwise drop is saved first. Platform mode only: each turn's query and conversational content is sent to the hosted api.cortexlayer.net (HTTPS, API-key authenticated) for storage/retrieval — no local/offline mode. Requires a free CortexLayer account and API key.

## How to install

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

```bash
hermes plugins install cortexlayer
```

2. Said no? Turn it on later:

```bash
hermes plugins enable cortexlayer
```

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
