Building Scalable Agentic Browser Automation and UI Testing with a Four-Layer Architecture
This video introduces a structured, four-layer approach called "Bowser" for building reusable and scalable agentic systems for browser automation and UI testing. It argues that by engineering a specific stack of skills, sub-agents, prompts, and a command runner, engineers can automate entire classes of work, significantly reducing manual effort. This framework is for developers looking to leverage AI agents for complex web interactions beyond simple task execution, aiming for repeatable success and increased productivity.
