What problem does it solve? Verifying frontend changes and testing web UI interactions manually is slow and repetitive. This Skill gives an AI agent direct control of a browser through a CLI, so it can open pages, inspect the accessibility tree, interact with elements, and capture screenshots without human intervention. ## Core Features & Use Cases - Snapshot-Based Interaction: Generate an accessibility tree with element refs (@e1, @e2) and use them to click, fill, type, select, and check elements deterministically. - Screenshots & Inspection: Capture viewport or full-page screenshots, read text/HTML/values from elements, and check visibility, enabled, or checked states. - Sessions & Debugging: Persist cookies and storage across commands with named sessions, view console logs and page errors, and run headed mode for visual debugging. - Use Case: After modifying a form in your Astro/Cloudflare CMS admin panel, open the page, snapshot the interactive elements, fill the title and content fields, click save, and screenshot the result to confirm the change works. ## Quick Start Use the agent-browser skill to open http://localhost:4321, take an interactive snapshot, and verify the page renders correctly.
