- Web tools and annotations: custom controls, suggested prompts, and their role in agent-compatible websites
- Examples and development context: scene editing, expense metadata, and defining annotations with HTML or JavaScript

For web developers and product teams, this overview offers a practical perspective on how to make site actions easier for users and their agents to discover. It focuses on capabilities and examples rather than a step-by-step implementation; viewers can use it to identify annotation or prompt ideas to explore in their own applications.
