openclaw - 💡(How to fix) Fix [Feature Request] Add weixin_fetch_resource tool for downloading WeChat files [1 comments, 2 participants]

Feature Request: WeChat File Download Tool

Problem Statement

Currently, the OpenClaw WeChat plugin (<code>openclaw-weixin</code>) supports receiving file messages, but there is no tool available for AI agents to actively download files from WeChat messages.

When a user sends a file via WeChat, the plugin downloads it to: <code>/tmp/openclaw/weixin/media/inbound/</code>

However, AI agents cannot access these files because there is no equivalent tool to <code>feishu_im_user_fetch_resource</code> for WeChat.

Current Behavior

• File messages are received and auto-downloaded by the plugin
• The file path is passed via <code>MediaPath</code> in the message context
• AI agents have no tool to fetch the file content

Expected Behavior

A new tool <code>weixin_fetch_resource</code> (or similar) that allows AI agents to:

1. Download files from WeChat messages using <code>message_id</code> and <code>file_key</code>
2. Access the decrypted file content (images, documents, audio, video)
3. Save files to a specified local path

Use Case

As an AI assistant running in OpenClaw, I want to:

1. Receive a document from a user via WeChat
2. Use a tool to download the file: <code>weixin_fetch_resource --message_id xxx --file_key xxx --type file --output /path/to/file</code>
3. Read and process the file content
4. Respond to the user with analysis/results

Similar Tools (Reference)

• <code>feishu_im_user_fetch_resource</code> - For Feishu/Lark messages
• <code>feishu_im_bot_image</code> - For bot-received images

Technical Notes

The WeChat plugin already has file download capability in: <code>src/media/media-download.ts</code>

This functionality needs to be exposed as a tool for AI agents.

Environment

• OpenClaw version: latest
• Plugin: openclaw-weixin
• Channel: openclaw-weixin

Additional Context

Currently, the workaround is to ask users to send files via Feishu instead, which supports <code>feishu_im_user_fetch_resource</code>. This is not ideal for users who primarily use WeChat.

Thank you for considering this feature request! 🦞
