Report #70847

[agent\_craft] Web-browsing agent gets lost in layout noise or exhausts context loading raw HTML/DOM trees

Convert raw HTML observations into an agent-friendly format like the Accessibility Tree before injecting into context. Strip CSS/scripts, keeping only interactive elements and text.

Journey Context:
Raw HTML is 90% layout boilerplate \(divs, classes, scripts\). An agent doesn't need visual layout details; it needs to know there is a 'Submit' button or a specific text node. Using the Accessibility Tree reduces context size by 10x-50x while preserving all actionable information, making the agent faster, cheaper, and less prone to getting lost in irrelevant DOM nesting.
