Claude Tag Update: Slack Agent Reads Full Context, Proactively Intervenes

Anthropic updated Claude's Slack integration (Claude Tag) so the agent now reads the full conversation context and can proactively jump in unprompted, with a 30% improvement in deciding when to act. Scott White frames this as 'multiplayer AI' — a strategic bet that enterprise value comes from collaborative agents, not solo chatbots. This changes team workflows and represents a significant shift in how Claude operates in enterprise communication tools.
