Capabilities
| Feature | Description |

Quick Start
1. Install
bash "$CLAUDE_SKILL_DIR/scripts/install.sh"The script will:
- Install Python dependencies (
dingtalk_stream,websockets) - Prompt for your DingTalk App Key & Secret (or read from env)
- Generate
config.json - Create
data/directory for conversation state - Optionally create a macOS LaunchAgent for 24/7 operation
2. Configure
Set credentials via environment variables (recommended):
export DINGTALK_APP_KEY="your_app_key"
export DINGTALK_APP_SECRET="your_app_secret"
export DINGTALK_WORKDIR="/path/to/your/project" # optionalOr edit config.json in the skill directory (see config.example.json).
3. Get Conversation ID
The bot needs a conversation ID to send messages. Two ways:
Auto (recommended): Start the Stream bot, then @mention it in a DingTalk group. The conv ID is saved automatically.
Manual: If you already have the openConversationId and robotCode:
mkdir -p "$CLAUDE_SKILL_DIR/data"
echo '{"openConversationId":"YOUR_ID","robotCode":"YOUR_ROBOT_CODE"}' > "$CLAUDE_SKILL_DIR/data/conv.json"Commands
Send a message
# Markdown (default)
python3 "$CLAUDE_SKILL_DIR/src/send.py" "**Bold** message with markdown"
# With custom title
python3 "$CLAUDE_SKILL_DIR/src/send.py" --title "Alert" "Server is down!"
# Plain text
python3 "$CLAUDE_SKILL_DIR/src/send.py" --text "Plain text message"Start the Stream Bot
python3 "$CLAUDE_SKILL_DIR/src/stream_bot.py"The bot will:
- Connect to DingTalk via Stream protocol
- Listen for all @mentions in groups where the bot is added
- Execute the message content via
claude -p "<message>" --continue - Reply with the result as a markdown message
