mac-node-snapshot
Overview
Uses node screen.record to record a 1-second clip and extract a high-quality PNG frame. This workflow bypasses common screencapture permission issues and ensures a reliable image return.
Quick start (single command, no scripts)
All paths are relative to {skill}.
bash
mkdir -p "{skill}/tmp" \
&& openclaw nodes screen record --node "<node>" --duration 1000 --fps 10 --no-audio --out "{skill}/tmp/snap.mp4" \
&& ffmpeg -hide_banner -loglevel error -y -ss 00:00:00 -i "{skill}/tmp/snap.mp4" -frames:v 1 "{skill}/tmp/snap.png"
When to use (trigger phrases)
Use this skill when the user asks:
- •"Take a screenshot"
- •"What is on my screen?"
- •"Capture the screen"
- •"Screenshot via screen.record"
Notes
- •Requirements:
ffmpeg(ask before installing). - •If the frame is black, ask the user to wake the screen and retry.
- •Use
readon{skill}/tmp/snap.pngto attach it to the reply.
Troubleshooting
- •screen_record fails (node disconnected): check
nodes status, ensure OpenClaw app is running/paired. - •screenRecording false: must grant Screen Recording in System Settings; cannot be bypassed.
- •Black frame: screen may be asleep/locked; ask the user to wake and retry.
