Feishu Image

This handles the complete workflow of uploading images to Feishu servers and sending them to recipients, which is useful because Feishu's standard messaging can be finicky with images. It works both as a standalone CLI tool and inside OpenClaw, where it automatically pulls credentials from the config. The dual mode setup is clever: you either set FEISHU_APP_ID and FEISHU_APP_SECRET as environment variables, or let OpenClaw handle it. Particularly handy when users ask to "send me a screenshot" in Chinese workflows. The error handling is thorough with specific codes for missing credentials, auth failures, and upload problems. One note: you'll need to set up a Feishu enterprise app with im:resource and im:message permissions first.
