Starting today, you can open and interact with tools in Claude. Build and update project timelines in Asana. Draft, edit and send Slack messages in a formatted preview. Visualize ideas as diagrams in Figma—all without switching tabs. Claude already connects to your tools and takes actions on your behalf. Now those tools show up right in the conversation, so you can see what's happening and collabo

When we released Claude Code, we expected developers to use it for coding. They did—and then quickly began using it for almost everything else. This prompted us to build Cowork: a simpler way for anyone—not just developers—to work with Claude in the very same way. Cowork is available today as a research preview for Claude Max subscribers on our macOS app, and we will improve it rapidly from here.

Now Claude can navigate, click buttons, and fill forms in your browser. Works with Claude Code and Claude Desktop. Available in beta to all paid subscribers.

Update: We've published Agent Skills as an open standard for cross-platform portability. (December 18, 2025) Since launching Skills, two of the biggest questions we’ve heard from customers are: "How do skills and MCP work together? When should I use one versus the other?" Model Context Protocol (MCP) connects Claude to third-party tools, and skills teach Claude how to use them well. When you combi

If you use AI coding agents, you face the same challenge: how do you give them enough context to understand your architecture, conventions, and workflows without repeating yourself? The problem compounds as your codebase grows. Complex module relationships, domain-specific patterns, and team conventions don't surface easily. You end up explaining the same architectural decisions, testing requireme

Y Combinator, a startup accelerator, has launched over 5,000 companies that have a combined valuation of over $800B since 2005, including household names like Airbnb, Stripe, and DoorDash. Today, agentic coding tools like Claude Code are fundamentally changing how YC startups build and scale. Founders can now ship products directly from the terminal, compressing development cycles from weeks to ho

Skills are custom instructions that extend Claude's capabilities for specific tasks or domains. When you create a skill via a SKILL.md file, you're teaching Claude how to handle specific scenarios more effectively. The power of skills lies in their ability to encode institutional knowledge, standardize outputs, and handle complex multi-step workflows that would otherwise require repeated explanati

Since introducing Skills, there's been interest in understanding how the various components of Claude's agentic ecosystem work together. Whether you're building sophisticated workflows in Claude Code, creating enterprise solutions with the API, or maximizing your productivity on Claude.ai, knowing which tool to reach for—and when—can transform how you work with Claude. This guide breaks down each

Update: We've added organization-wide management for skills, a directory featuring partner-built skills, and published Agent Skills as an open standard for cross-platform portability. (December 18, 2025) Claude can now use Skills to improve how it performs specific tasks. Skills are folders that include instructions, scripts, and resources that Claude can load when needed. Claude will only access

Share your Claude Code setup with pluginsSlash commands, agents, MCP servers, and hooks are all extension points you can use to customize your experience with Claude Code. As we've rolled them out, we've seen users build increasingly powerful setups that they want to share with teammates and the broader community. We built plugins to make this easier. Plugins are a lightweight way to package and s
