Summary
On August 19, 2026, Anthropic graduated a wave of Claude Developer Platform capabilities to general availability - the computer use tool, the Files API, Agent Skills and the Skills API, and Admin API user-management endpoints all dropped their beta headers - and launched a new browser-use tool for driving an application-hosted browser. It also added allow/block domain lists for managed-agent web search and fetch.
What changed
Anthropic moved the computer use tool (new computer_toolset_20260801), the Files API, Agent Skills / the Skills API, and Claude Enterprise Admin API user-management endpoints out of beta on the Claude API, and launched the browser use tool (browser_toolset_20260801) that reads a page's accessibility tree and drives forms, tabs, downloads, and file upload inside a hosted browser viewport. Managed-agent web_search/web_fetch gained allowed_domains/blocked_domains controls.
Why it matters
Graduating computer use, Skills, and Files from beta signals Anthropic considers its agent tool stack production-grade, letting teams build without beta headers or churn risk. The dedicated browser-use tool targets web automation more precisely than full-desktop control, and domain allow/block lists plus Admin API GA address the governance enterprises need to deploy agents at scale.
