Electron App Automation (agent-browser)

Automate Electron desktop apps like Slack, VS Code and Discord by connecting agent-browser to their Chrome DevTools Protocol port.

What it does

Electron apps run on Chromium, so they all accept the --remote-debugging-port flag. This skill teaches Claude to use that to drive desktop apps with the same snapshot-and-interact loop used for web pages.

  • Launch commands with remote debugging for macOS, Linux and Windows
  • Connect to the CDP port with agent-browser connect
  • Use snapshot -i to enumerate interactive elements, then click/fill by ref (@e5)
  • Switch between windows and <webview> targets via tab; drive multiple apps at once via --session
  • Screenshots, text extraction, JSON state dumps
  • Troubleshooting for connection refused, missing elements, and stubborn input fields

Who it's for

  • QA engineers and developers testing Electron applications
  • Anyone automating repetitive work in Slack, Notion, Linear, and similar tools
  • People scripting screenshots or data extraction from desktop apps

Examples

  1. "Open Slack, go to a channel, and capture the screen" → relaunch on port 9222, connect, snapshot, click, screenshot
  2. "Control VS Code and Slack at the same time" → separate --session vscode and --session slack sessions
  3. "Click a button inside this app's embedded webview" → list targets with tab, switch to the webview, then click

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the plugins/agent-browser/skills/electron folder from the GitHub repo fcakyon/claude-codex-settings into my ~/.claude/skills/electron/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/fcakyon/claude-codex-settings.git && mkdir -p ~/.claude/skills && cp -r claude-codex-settings/plugins/agent-browser/skills/electron ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Confirm Node.js is installed (node -v).
  2. Make the agent-browser CLI available: npm i -g agent-browser, or verify with npx agent-browser --help.
  3. Clone the repo: git clone https://github.com/fcakyon/claude-codex-settings.git
  4. Copy the skill: mkdir -p ~/.claude/skills && cp -r claude-codex-settings/plugins/agent-browser/skills/electron ~/.claude/skills/
  5. Restart Claude Code and ask something like "automate the Slack app" to trigger it.
  6. If the target app is already running, quit it fully and relaunch with the --remote-debugging-port flag.
