WeChat Sender Pro

Problem

When you are away from your computer, you may still need to send a local image, spreadsheet, or file to a WeChat contact. WeChat does not provide an easy official sending API, and a naïve automation script often fails against the logged-in PC client, especially when the window is minimized, obscured, contaminated with leftover search text, or pointed at the wrong contact.

How It Works

The skill drives the Windows WeChat UI through GUI automation and closes the loop of finding a contact, confirming the target, pasting content, and sending it. Core capabilities include:

• Use send_message.py for text, send_image.py for images, and send_file.py for files.
• Use find_file.py with --name, --dirs, --ext, and --limit to locate local files before sending.
• Prefer batch_send.py to chain search, confirmation, and sending into one workflow.
• Use the wechat_sender.py library for window discovery, foreground switching, input cleanup, and message delivery.

The workflow follows “search, confirm, then send”: press Ctrl+F, type the contact name, press Enter twice to enter the chat, click the input area, then run Ctrl+A, Delete, and Ctrl+A to remove residual search text before pasting the payload. Images are converted to BMP/DIB so WeChat can paste them reliably, while window activation uses AttachThreadInput, keybd_event(Alt), and SetForegroundWindow to avoid selecting hidden auxiliary windows when WeChat is minimized or backgrounded.

Boundaries and Notes

This approach requires Windows, Python 3.x, a logged-in WeChat PC client, and a contact that can be found through WeChat search. It is GUI automation rather than an official WeChat API, so it is better suited to low-volume, human-verified workflows than high-concurrency, audited messaging. Add delays when sending batches and validate the flow on a test account first.
