lightcone-browse

# Lightcone Browse Delegate browser tasks to a cloud computer powered by Lightcone. Northstar sees the screen, decides what to click, type, or scroll — and acts. You describe what you want done, Northstar does it. ## When to use Lightcone - No local browser available (headless, Docker, server deployments) - Need parallel sessions (multiple sites at once) - Vision-based automation (Northstar reads the screen — no selectors, no scripts to maintain) - Desktop or browser environments ## Tool: `lightcone_browse` ### Parameters | Parameter | Required | Description | |-----------|----------|-------------| | `instruction` | Yes | Plain language task for Northstar | | `url` | No | Starting URL to navigate to first | | `maxSteps` | No | Max steps before stopping (default: 50) | ### Example instructions **Price checking:** ``` instruction: "Find the current price of a MacBook Air M4 on Amazon" url: "https://www.amazon.com" ``` **Data extraction:** ``` instruction: "Go to the pricing page and extract all plan names, prices, and feature lists" url: "https://example.com/pricing" ``` **Form filling:** ``` instruction: "Fill out the contact form with name 'Jane Doe', email 'jane@example.com', and message 'Hello'" url: "https://example.com/contact" ``` ## Tips for good instructions - Be specific about what "done" looks like: "find the price" not "look around" - Name the exact elements: "click the Sign In button" not "log in somehow" - For multi-step tasks, describe the sequence: "First search for X, then sort by price, then get the top 3 results" - Include what to extract: "tell me the title, price, and rating" ## How it works 1. Lightcone creates a cloud computer with a browser 2. Northstar sees the screen via screenshots 3. It decides what to click, type, or scroll — step by step 4. When done, it returns the page content and a screenshot 5. The computer is automatically shut down For step-by-step manual control, see the **lightcone-session** skill.
