We built Agent Builder around a simple idea: working with an agent should feel like working with a teammate.

There's now a central Chat agent with access to every tool in your workspace — Slack, Gmail, Linear, and any connected MCP server — so you can ask questions and take action without setting up a dedicated agent first. When a conversation gets useful, turn it into a recurring agent with one click: no prompt engineering, no if/then logic, just your conversation as the setup.

You can also now upload files directly into chat — CSVs, images, docs, style guides — and your agent can act on them immediately. And all your tools live in one registry where admins can connect, authenticate, and manage access across the entire workspace.
