Computer Use, Skills API, and Files API Are Now GA — Building Production Agents Just Got Easier!

Hey, it's me, Shiichan! Today I've got a big update from the Claude platform.

Claude Blog claude.com

What was announced?

The Claude blog announced that three capabilities — Computer Use, the Skills API, and the Files API — are now generally available (GA). All three are foundational building blocks for running agents in production.

What changes

Here's what each one brings:

Computer Use

  • Agents can view screenshots and interact with software by clicking, typing, and scrolling — even applications with no API
  • New multi-action turns let an agent take several actions in a single turn, cutting down completion time
  • It's now HIPAA-eligible for regulated workloads under a BAA

Browser Use Tool (new)

  • Extends computer use specifically to web applications
  • Combines screenshot-based perception with page structure analysis, letting agents target specific web elements more reliably than pixel-based clicking alone

Skills API

  • Upload and version custom skills — folders containing instructions, scripts, and templates
  • Skills only load when they're relevant to the task at hand
  • They run inside Claude's code sandbox, so there's no need to host anything yourself
  • Skill management is handled through a simplified API

Files API

  • Document storage built for agent workflows
  • Upload a file once and reference it by ID in later requests
  • Improvements include automatic expiration, 5x higher rate limits, and 1TB of storage per organization

Dive Deep

The post walks through a claims-processing agent as an example: it reads intake documents via the Files API, follows the team's procedures via the Skills API, completes portal submissions using the browser use tool, and saves the confirmations as files — all in one workflow.

Availability is spelled out clearly too:

  • Claude Platform: available now
  • Microsoft Foundry: Skills API and Files API available
  • Google Cloud Vertex AI: updates coming soon

Wrap-up

  • Computer Use, the Skills API, and the Files API are all now generally available.
  • Computer Use gained multi-action turns and HIPAA eligibility, making it more production-ready.
  • The new Browser Use Tool lets agents target web elements more reliably.
  • The Skills API simplifies managing skills, and the Files API simplifies passing files around.
  • Beyond the Claude Platform, this is rolling out to Microsoft Foundry and Google Cloud Vertex AI too — a very direct win for anyone building production agents.
