Stagehand Python 4.0.3a0.dev1483 adds stagehand_facade tool surface for eval benchmarking
A dev release of Stagehand Python introduces a facade tool surface that allows evals to benchmark the exact byte-identical interface shipped to Claude Code, Codex, and Pi integrations.
Briefing
- browserbase/stagehand releases: A dev release of Stagehand Python introduces a facade tool surface that allows evals to benchmark the exact byte-identical interface shipped to Claude Code, Codex, and Pi integrations.
Why it matters
This change closes the loop on eval harness consolidation by ensuring benchmarks test the same facade that third-party integrations actually use. For practitioners, it means evaluation results will more accurately reflect real-world performance, reducing the gap between lab metrics and production behavior in agentic extraction workflows.
