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.

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 | $0.00112 | $0.01636 |
| Opus 5 | $0.00056 | $0.00818 |
| Sonnet 5 | $0.00022 | $0.00327 |
| Haiku 4.5 | $0.00011 | $0.00164 |
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 3d 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.

The opening of the file, as written. The whole thing — 237 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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

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.

electron is a skill published in the GitHub repository vercel-labs/agent-browser (41,715 stars, last pushed yesterday), licensed Apache-2.0. It adds 112 tokens to every session and 1,636 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
