Anthropic launches Claude Tag — Claude as a teammate in Slack channels

What's new

• @Claude in a Slack channel: tag to delegate asynchronous work.
• One shared Claude identity per channel — everyone sees the same context.
• Persistent memory of channel conversations, tools, data, and codebases.
• Ambient mode: Claude proactively flags information and follows up on unresolved threads.
• Self-scheduling: can plan its own work over extended time windows.
• Runs on Claude Opus 4.8; admins set per-channel permissions and a monthly spend cap.
• Internally at Anthropic, Claude ships 65% of the product team's code.

Why it matters

Anthropic is turning Slack into a delegation surface — a direct attack on Slack's own AI and on Microsoft Copilot in Teams. It elevates Claude from "chat app" to permanent teammate.

How to try it
