Anthropic's Claude Tag Brings Persistent, Proactive AI Into Slack Workspaces

Anthropic released Claude Tag on 23 June in research preview—a Slack-integrated AI agent that learns organizational context from message history and operates proactively rather than on demand. Unlike reactive assistants, Claude Tag accumulates institutional knowledge, recognizing recurring decisions and project patterns without explicit prompting. The shift from pull-based queries to ambient collaboration marks a departure in how AI integrates into team infrastructure.
