+# Mistral Vibe
+
+T3 Code runs [Mistral Vibe](https://github.com/mistralai/mistral-vibe) as an agent through its ACP
+server, `vibe-acp`, using your own Mistral account and Vibe configuration.
+
+## Set Up Mistral Vibe
+
+1. Install Vibe on the machine running the T3 Code server:
+   `curl -LsSf https://mistral.ai/vibe/install.sh | bash`, or `uv tool install mistral-vibe`.
+2. Run `vibe --setup` once in a terminal. You can instead set `MISTRAL_API_KEY` in the Mistral Vibe
+   provider's **Mistral API key** field.
+3. Open **Settings → Providers**, add **Mistral Vibe**, and enable it.
+
+If `vibe-acp` is not on the server's `PATH`, set its **Binary path**. The installer usually puts it
+in `~/.local/bin`.
+
+## Models
+
+The model picker lists the models Vibe offers once it is signed in. **Default** keeps the model
+Vibe itself would start with. That model shows a **Thinking** setting with the levels Vibe offers
+for it; other models run at Vibe's own thinking setting.
+
+After changing your Vibe configuration or account, refresh provider status in **Settings →
+Providers** to reload the model list.
+
+## Permission Modes
+
+The permission mode picks the Vibe agent a thread runs as:
+
+- **Supervised** runs Vibe's `ask` agent. Commands and file changes wait for your approval; reads
+  and searches run without asking.
+- **Auto-accept edits** runs `accept-edits`: Vibe applies file edits itself and asks before
+  other tools.
+- **Full access** runs `auto-approve`, which runs every tool without asking.
+
+Vibe offers no **Auto** mode in T3 Code.
