What this skill does
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. The workflow: 1. Start a browser session 2. Navigate to the target page 3. Snapshot to get the page structure with element refs 4. Automate using refs from the snapshot Run actionbook <command> --help for full usage and examples of any command. Browser Automation Every browser command is stateless — pass --session and --tab explicitly. No "current tab" — you can run commands on any session/tab in parallel. Start a session Both --session and --set-session-id are get-or-create: they reuse a Running session with the given ID, or create one if not found. If --profile is passed and does not match the session's bound profile, the command fails with SESSIONPROFILEMISMATCH. Core workflow: snapshot, act, wait Snapshot refs snapshot labels every element with a ref (e.g. @e3, @e7). Use these refs as selectors in any command — they are the recommended way to target elements. …
