Feishu Screenshot

Feishu Screenshot

Capture macOS screenshots and send to Feishu conversations.

Quick Start

# 1. Capture screenshot to temp directory
screencapture -x "$TMPDIR/screenshot.png"

# 2. Send to Feishu
# Use message tool with media parameter

Sending Images to Feishu

Use the message tool with media parameter (NOT base64):

message(action=send, media="/path/to/image.png", channel="feishu")

Or reply to current conversation (auto-inferred target):

message(action=send, media="/path/to/image.png")

OpenClaw handles:

1. Upload image via POST /open-apis/im/v1/images -> get image_key
2. Send message with msg_type: image and the key

Important Notes

Use $TMPDIR not /tmp

• macOS temp directory: /var/folders/.../T
• OpenClaw file access restricts to os.tmpdir() and workspace
• /tmp may not be accessible

Use media parameter

• Pass file path directly to media parameter
• Do NOT use buffer (base64) parameter
• Let OpenClaw handle the upload flow

Full Example

Taking a screenshot and sending to Feishu:

# Capture
SCREENSHOT_PATH="$TMPDIR/screenshot_$(date +%s).png"
screencapture -x "$SCREENSHOT_PATH"

Then use message tool:

message(
  action=send,
  media="$SCREENSHOT_PATH",
  channel="feishu"
)
