Browser action engine. Provides up-to-date action manuals for the modern web — operate any website instantly, one tab or dozens, concurrently.
Pre-verified page actions and selectors for website automation without runtime discovery.
Search a library of documented page interactions by task intent, then retrieve structured DOM details with tested CSS selectors ready for browser commands
Browser commands cover navigation, form filling, clicking, text extraction, screenshots, and waiting for page changes
Handles login walls by pausing automation and asking the user to complete authentication manually in the same session
Daemon mode (Unix/CDP) maintains a persistent WebSocket connection per profile, eliminating per-command connection overhead
Falls back to live accessibility tree snapshots when selectors become outdated due to website changes
When to Use This Skill
Activate when the user:
Needs to do anything on a website ("Send a LinkedIn message", "Book an Airbnb", "Search Google for...")
Asks how to interact with a site ("How do I post a tweet?", "How to apply on LinkedIn?")
Wants to fill out forms, click buttons, navigate, search, filter, or browse on a specific site
Wants to take a screenshot of a web page or monitor changes
Builds browser-based AI agents, web scrapers, or E2E tests for external websites
Automates repetitive web tasks (data entry, form submission, content posting)
Needs to operate multiple websites or tabs concurrently
How It Works
Actionbook provides up-to-date action manuals for the modern web. Action manuals tell agents exactly what to do on a page — no parsing, no guessing.
Why this matters:
10x faster — action manuals provide selectors and page structure upfront. No snapshot-per-step loop needed.
Accurate — handles SPAs, streaming components, dropdowns, date pickers, and dynamic content reliably.
Concurrent — stateless architecture with explicit --session/--tab. Operate dozens of tabs in parallel.don't have the plugin yet? install it then click "run inline in claude" again.
