A workflow for controlling Electron desktop applications—programs such as VS Code, Slack, Discord, Figma, Notion, and Spotify—through their built-in Chromium debugging connection.

Use it to launch or connect to a running Electron app, click and inspect its interface, automate tasks, or test the desktop application.

It gives the agent a repeatable way to discover buttons and other controls, interact with the app, and capture screenshots for testing or automation.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00112	$0.01636
Opus 5.5	$0.00045	$0.00654
Sonnet 5.5	$0.00022	$0.00327
Haiku 4.5	$0.00011	$0.00164

Security

Grade A, and why

electron scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to electron — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Electron App Automation

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.

Core Workflow

Launch the Electron app with remote debugging enabled
Connect agent-browser to the CDP port
Snapshot to discover interactive elements
Interact using element refs
Re-snapshot after navigation or state changes

# 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
agent-browser screenshot slack-desktop.png

Launching Electron Apps with CDP

Every Electron app supports the --remote-debugging-port flag since it's built into Chromium.

macOS

# 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

# Figma
open -a "Figma" --args --remote-debugging-port=9225

# Notion
open -a "Notion" --args --remote-debugging-port=9226

# Spotify
open -a "Spotify" --args --remote-debugging-port=9227

Linux

slack --remote-debugging-port=9222
code --remote-debugging-port=9223
discord --remote-debugging-port=9224

Windows

"C:\Users\%USERNAME%\AppData\Local\slack\slack.exe" --remote-debugging-port=9222
"C:\Users\%USERNAME%\AppData\Local\Programs\Microsoft VS Code\Code.exe" --remote-debugging-port=9223

Important: If the app is already running, quit it first, then relaunch with the flag. The --remote-debugging-port flag must be present at launch time.

Connecting

# Connect to a specific port
agent-browser connect 9222

# Or use --cdp on each command
agent-browser --cdp 9222 snapshot -i

# Auto-discover a running Chromium-based app
agent-browser --auto-connect snapshot -i

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
