Automates browser workflows and web interactions with persistent page state for complex multi-step tasks.
The Dev Browser skill enables Claude to perform sophisticated browser automation by maintaining a live session state across multiple script executions. Unlike standard stateless tools, this skill allows for incremental workflows where Claude can navigate, log in, and interact with web elements while preserving the environment between steps. It offers dual modes—a standalone Chromium instance for clean sessions and an Extension Mode for leveraging existing user profiles—alongside advanced features like YAML ARIA snapshots for reliable element targeting and screenshot capabilities for visual debugging.
