1. Parse the user's request to determine the message content, recipient, and message type (text, image, or file).
2. Load WeCom API configuration from `~/.openclaw/openclaw.json`, including proxy settings.
3. If sending an image or file, validate the file path and type, ensuring it meets WeCom's size and format requirements.
4. Execute the `scripts/send_wecom.py` script with the appropriate arguments (message content, file path, recipient).
5. Handle potential errors, such as exceeding the message length limit or file upload failures.
6. Report the outcome of the message sending operation to the user.
