What Is Claude Tag? How Anthropic's Slack AI Teammate Works (2026)

Anthropic launched Claude Tag on 23 June 2026: a way to work with Claude inside Slack as a shared, always-on teammate. Tag @Claude and it plans a task, uses the tools you grant it, and replies in-thread. It is multiplayer, learns from the channel, can take initiative, and works asynchronously over hours or days. It runs on Opus 4.8, is in beta for Enterprise and Team, and replaces the old Claude in Slack app.
