Nextcloud Talk platform adapter for Hermes Agent, in two modes behind one plugin: a webhook bot (Nextcloud Talk Bot API, HMAC-SHA256 signed, with an explicit body-size cap and a nonce-replay cache ahead of payload parsing) and a real Nextcloud user account (app password, long-polling the Chat REST API, with federation-invite support, per-room mention/watch/free modes, and an agent-to-agent loop guard plus active-listening context for multi-agent rooms). Mode is picked automatically by which credential is configured. No extra SDKs -- aiohttp for bot mode, httpx for user mode, both already Hermes dependencies.

## Good to know before installing

Connects to your Nextcloud server either as a Talk bot (HMAC-verified webhook listener, 127.0.0.1:18797 by default) or as a real Nextcloud user with an app password (long-polls the Chat API and auto-accepts federation invites only from NEXTCLOUD_TALK_ALLOWED_INVITERS); in user mode, unanswered room messages from allowed senders (up to 40 per room by default) and, for rooms listed in NEXTCLOUD_TALK_ROOM_MODES or with room_rules_all_rooms on, the room description are added to the agent's next turn in that room.

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 nextcloud-talk-platform
```

2. Said no? Turn it on later:

```bash
hermes plugins enable nextcloud-talk-platform
```

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
