+# Feishu Reaction Tool
+
+The Feishu reaction tool allows agents to add, remove, and list emoji reactions on messages.
+
+## Setup
+
+Enable the reaction tool in your Feishu config:
+
+```json
+{
+  "channels": {
+    "feishu": {
+      "tools": {
+        "reaction": true
+      }
+    }
+  }
+}
+```
+
+## Usage
+
+### Add a reaction
+
+```json
+{
+  "action": "add",
+  "message_id": "msg_xxxxxx",
+  "emoji_type": "THUMBSUP"
+}
+```
+
+### Remove a reaction
+
+```json
+{
+  "action": "remove",
+  "message_id": "msg_xxxxxx",
+  "reaction_id": "react_xxxxxx"
+}
+```
+
+### List reactions
+
+```json
+{
+  "action": "list",
+  "message_id": "msg_xxxxxx"
+}
+```
+
+### List reactions with specific emoji
+
+```json
+{
+  "action": "list",
+  "message_id": "msg_xxxxxx",
+  "emoji_type": "HEART"
+}
+```
+
+## Available Emoji Types
+
+Common emoji types:
+
+- `THUMBSUP` 👍
+- `THUMBSDOWN` 👎
+- `HEART` ❤️
+- `SMILE` 😊
+- `GRINNING` 😀
+- `LAUGHING` 😂
+- `CRY` 😢
+- `ANGRY` 😠
+- `SURPRISED` 😲
+- `THINKING` 🤔
+- `CLAP` 👏
+- `OK` 👌
+- `FIST` ✊
+- `PRAY` 🙏
+- `FIRE` 🔥
+- `PARTY` 🎉
+- `CHECK` ✅
+- `CROSS` ❌
+- `QUESTION` ❓
+- `EXCLAMATION` ❗
+
+For a complete list, see the [Feishu emoji documentation](https://open.feishu.cn/document/server-docs/im-v1/message-reaction/emojis-introduce).
+
+## Examples
+
+### React to a message with thumbs up
+
+```typescript
+await feishu_reaction({
+  action: "add",
+  message_id: "msg_123",
+  emoji_type: "THUMBSUP"
+});
+```
+
+### Check all reactions on a message
+
+```typescript
+const result = await feishu_reaction({
+  action: "list",
+  message_id: "msg_123"
+});
+// Returns: { reactions: [{ reactionId, emojiType, operatorType, operatorId }] }
+```
+
+### Remove a specific reaction
+
+```typescript
+await feishu_reaction({
+  action: "remove",
+  message_id: "msg_123",
+  reaction_id: "react_456"
+});
+```
+
+## Error Handling
+
+The tool returns errors in the following cases:
+
+- Missing required `emoji_type` for add action
+- Missing required `reaction_id` for remove action
+- Invalid action type
+- API failures (network, auth, etc.)
+
+Example error response:
+
+```json
+{
+  "error": "emoji_type is required for add action"
+}
+```
