openclaw - 💡(How to fix) Fix [Feature] Auto-download parent message files in Feishu reply

Summary

Auto-download parent message files when bot receives a reply in Feishu group chat

Problem to solve

When a user in Feishu group chat:

1. Sends a file (e.g., xlsx)
2. Right-clicks the file message and selects "Reply"
3. @bot and describes their request

The bot only receives the reply text, cannot access the parent message (which contains the file).

This prevents AI from processing files shared in this common workflow pattern.

Proposed solution

In Feishu message processing pipeline:

1. When message contains parent_id, automatically call GET /im/v1/messages/{parent_id} to get parent message
2. Parse parent message type; if file/audio/video, extract file_key
3. Download resource via /im/v1/messages/{parent_id}/resources/{file_key}
4. Attach resource to AI context as media

Technical: Feishu events already include parent_id field. Just add parent message resource download to existing message parsing logic.

Impact

• Affected: All users who want AI experts to process files in Feishu group chats
• Severity: High (blocks file processing workflows)
• Frequency: Multiple times daily
• Consequence: Users must manually describe file content instead of @expert with file in reply

Evidence/examples

Reproduction steps:

1. Upload xlsx file in Feishu group
2. Right-click file message, select "Reply"
3. @AI expert in reply
4. AI receives reply but cannot access file content
