+# Group Messages
+
+This documentation covers WhatsApp group chat functionality for Clawd, enabling the agent to participate in groups while remaining dormant until activated.
+
+## Key Features
+
+### Activation Modes
+
+The system supports two modes:
+- `mention` (default): requires @-ping to respond
+- `always`: responds to every message
+
+### Group Policy Control
+
+Access is managed through `groupPolicy` settings with three options:
+- `open`
+- `disabled`
+- `allowlist` (default)
+
+The default `allowlist` blocks messages until senders are explicitly permitted.
+
+### Separate Sessions
+
+Each group maintains its own session context independent from direct messages. Session keys look like `agent:<agentId>:whatsapp:group:<jid>` to keep group and DM conversations isolated.
+
+### Context Injection
+
+Unread group messages (up to 50 by default) are automatically included in prompts, labeled as "[Chat messages since your last reply - for context]" with the current message marked separately.
+
+### Sender Attribution
+
+Each message batch includes `[from: Sender Name (+E164)]` so the agent knows who is speaking.
+
+## Configuration
+
+The setup requires adding mention patterns and group settings to `openclaw.json`, including regex patterns for display-name recognition and numerical fallbacks.
+
+```json5
+{
+  agents: {
+    list: [
+      {
+        id: "main",
+        groupChat: {
+          mentionPatterns: ["@openclaw", "openclaw", "\\+15555550123"],
+          historyLimit: 50,
+        },
+      },
+    ],
+  },
+}
+```
+
+## Usage
+
+Simply @-mention the bot in a group (using `@openclaw` or the phone number), and only allowlisted senders can trigger responses unless open policy is enabled. Group-specific commands like `/verbose on` apply only to that session.
