I want to take a single quick interactive snapshot of an Electron app running on port 9225 without persisting a session or running a separate explicit connect step first. How can I pass the port inline for a one-off snapshot command?
| Checked | Without skill | With skill |
|---|---|---|
| Uses the --cdp flag with port 9225 directly on the snapshot command | Passed | Passed |
| Includes the -i flag on snapshot to discover interactive elements | Missed | Passed |
The instructions your model reads when the skill loads.
Automate any Electron desktop app using agent-browser. Electron apps are built on Chromium and expose a Chrome DevTools Protocol (CDP) port that agent-browser can connect to, enabling the same snapshot-interact workflow used for web pages.
# Launch an Electron app with remote debugging
open -a "Slack" --args --remote-debugging-port=9222
# Connect agent-browser to the app
agent-browser connect 9222
# Standard workflow from here
agent-browser snapshot -i
agent-browser click @e5

Every Electron app supports the --remote-debugging-port flag since it's built into Chromium.
# Slack
open -a "Slack" --args --remote-debugging-port=9222
# VS Code
open -a "Visual Studio Code" --args --remote-debugging-port=9223
# Discord
open -a "Discord" --args --remote-debugging-port=9224
