Anthropic launched Claude Tag, a Slack integration that lets teams delegate work to Claude as a persistent team member rather than a chat interface.

What happened

Anthropic introduced Claude Tag, a new way to work with Claude in Slack where the AI joins as a team member with access to selected channels, tools, data, and codebases. Users can tag Claude into tasks asynchronously and have it execute work in the background. The feature is launching in beta for Claude Enterprise and Team plans.

Why it matters

Claude Tag shifts Claude from a one-user chat tool to a multiplayer, asynchronous delegation layer. Anthropic's internal Claude Code team reported that Claude has been writing 65% of their product team's code using Claude Tag all year, which suggests the feature may change how teams approach coding and operational work. This represents what Andrej Karpathy called the 'third major redesign of LLM UIUX'—moving from a website, to a desktop app, to a persistent organizational entity with tool and context access.

What to watch

Claude Tag includes features like ambient monitoring mode (responding to channels without being tagged), git webhooks that can wait for long-running dependencies for days, A/B test monitoring with guardrails, and the ability to tag in coworkers and summarize threads into actionable docs. The product requires explicit permission setup and scope control rather than blanket workspace access, indicating teams will need to configure agent permissions carefully at deployment.
