Claude Code Major Upgrade: Claude Tag Released, AI Embedded as Team Member in Slack

On June 23, 2026, Anthropic officially launched Claude Tag, a new feature that embeds an AI assistant as a team member in Slack. Users can simply @Claude in a channel to assign tasks, and Claude will automatically break them down, invoke tools, and deliver results in the thread. Claude Tag runs on Opus 4.8 and is currently available in Beta for Claude Enterprise and Team users, included free with Claude Cowork at no additional cost.

Core Capabilities

• Shared Identity: Only one Claude interacts with everyone in the same channel, visible to all members, allowing接力 conversations.
• Persistent Memory: Claude accumulates channel context, eliminating the need to repeat background information, with permission isolation ensuring private channel information is not leaked.
• Proactive Intervention (Ambient Mode): When enabled, Claude can remind about overlooked discussions, follow up on unresolved issues, and flag items requiring decisions.
• Asynchronous Execution: Tasks can progress across hours or even days, with proactive reporting upon completion.

Internal Usage and Data

Anthropic revealed that 65% of its product team's code was generated by an internal version of Claude Tag. Boris Cherny, the father of Claude Code, stated that over the past few months, Claude Tag has reshaped how the team uses Claude and is expanding beyond engineering into areas such as tracking product metrics, handling support tickets, and locating bugs.

Industry Commentary

Andrej Karpathy called this the third major revolution in LLM user interfaces: from web chat to desktop apps, and now to independent, persistent team entities with organizational context.

Deployment and Permissions

• Administrators can configure different tools and data access permissions for different channels, creating multiple "Claude identities."
• Organization-level and channel-level token consumption caps can be set, with operation logs and task initiators viewable.
• Setup process: Connect Slack Workspace → Configure tool permissions → Set monthly spending cap → Test in private channels.
• Claude Tag will replace the existing Slack version of the Claude app, with a 30-day migration period for administrators.

Competitive Landscape

OpenAI's Workspace Agents follow a no-code approach, Google's Gemini is embedded in the Workspace suite, while Anthropic bets on "embedded teammates," emphasizing security and collaboration. All three point to the shift of AI from a tool to a long-term team member.
