feature announcement

Anthropic has announced a series of significant updates to the Claude platform, making several key tools and APIs generally available and introducing new capabilities for Claude Agents. The Computer Use, Browser Use, Files, Agent Skills, and Enterprise Admin APIs have all reached GA, enhancing how developers build and manage AI applications. These updates improve agent interaction with external systems, streamline file handling, and provide better control over agent behavior, while also offering improved observability in the Claude Console. These changes primarily affect developers and architects leveraging the Claude API for agent development, with newly GA tools and APIs supported across Claude Fable 5, Mythos 5, Opus 5, Sonnet 5, and Opus 4.8 models.

  • Computer Use Tool for Claude API Reaches General Availability

    The `computer_toolset_20260801` is now generally available on the Claude API, removing the beta header. This GA version offers new features like batch actions and `zoom` enabled by default, with per-member configuration support, though migrating from older beta versions requires adjusting request shapes.

  • New Browser Use Tool for Client-Hosted Browsers Launched

    Anthropic has launched the `browser_toolset_20260801`, a client toolset designed to drive a browser hosted by the application. This tool enables agents to interact with web pages by reading accessibility trees, managing tabs, handling form input, reporting downloads, and optionally uploading files.

  • Claude API Files API Now Generally Available

    The Files API (`/v1/files`) has transitioned to general availability on the Claude API, no longer requiring a beta header. The GA response format includes file expiration and pagination for listing files, while requests retaining the beta header continue to use the previous format.

  • Agent Skills API and Enterprise Admin API Reach General Availability

    Both Agent Skills and the Skills API (`/v1/skills`) are now generally available on the Claude API, removing the need for their respective beta headers. Additionally, user management endpoints of the Admin API for Claude Enterprise organizations have reached GA, streamlining member, invite, group, and custom role management.

Enhancements (2) ›
  • Managed Agents Gain Granular Domain Restrictions and Memory Stores

    Claude Managed Agents can now restrict `web_search` and `web_fetch` tool access to specific domains using `allowed_domains` or `blocked_domains` in their configurations. Furthermore, self-hosted sandboxes for Managed Agents can now attach and sync memory stores, enhancing agent persistence and context.

  • Redesigned Session Viewer in Claude Console for Enhanced Observability

    The session viewer within the Claude Console has been redesigned to improve observability for Managed Agents. It now features a timeline minimap, a transcript grouped by model request, and an Inspector panel providing detailed insights into session costs, raw events, tool statistics, and mounted resources.
