Verified agents with Stagehand

Stagehand 3.3.0 is live.

Verified mode for improved agent identity. Sessions get a verifiable identity that helps on sites that gate bot traffic.

Plus:

• Adaptive thinking with Anthropic models. Claude CUA now scales the extended-thinking budget to match task complexity — faster on simple steps, deeper when it counts
• Agent usage in stagehand.metrics. agent.execute() calls now contribute to stagehand.metrics on API-backed sessions, so token counts and model calls land where you expect them
• Strict structured outputs. Supported model paths now use strict JSON schema enforcement, eliminating malformed responses on extract() and other structured calls
• Clearer file upload elements. File inputs are now explicit in the page snapshot, so agents can identify and drive upload flows reliably
