Anthropic launched Claude Tag on June 23, 2026 — a new way for teams to work with Claude that starts on Slack. Rather than a one-off assistant you summon per-tab, Claude Tag gives teams a shared, persistent @Claude that joins their channels, builds context over time, and takes on work autonomously while people get on with other things.
The release replaces Anthropic's earlier Claude in Slack app. Workspace administrators have a 30-day window to opt in and migrate.
What Claude Tag actually does
The core mechanic is simple: you grant Claude access to a Slack channel, connect it to whatever tools and data you choose, then tag @Claude with a task in plain language. Claude breaks the task into stages, works through them using its connected tools, and reports back in the thread when it's done.
What makes Claude Tag different from a basic Slack integration are three layers built on top of that:
Multiplayer by design. There is one @Claude per channel, visible to everyone. Anyone can see what it's working on and pick up a thread someone else started — no handoff friction, no duplicated context.
Persistent memory. As Claude follows along with a channel, it builds a working model of the team's projects, terminology, and recurring needs. You stop explaining things from scratch with every new request. Over time, Claude gets faster and more accurate simply because it knows the context.
Ambient mode. If enabled, Claude monitors channels proactively without being tagged. It flags relevant information from across the channels it's in and the tools it's connected to, follows up on threads or tasks that have gone quiet, and keeps the team informed without needing to be prompted.
Enterprise controls
Claude Tag was built with enterprise data security in mind from the start. Workspace administrators control which tools and data @Claude can access, and they do so at the channel level. That granularity matters: a product team's @Claude can have different access than the legal team's — each scoped to the specific context and sensitivity of that workspace.
What Anthropic says about internal use
Anthropic is not positioning this as an experiment. The company says tagging @Claude is now one of the main ways it gets things done internally, with 65% of its product team's code created by their internal version of Claude Tag.
More tellingly, the use has spread beyond engineering. Internal teams use Claude Tag to chase down product metrics and data, work through support tickets, and find the root causes of tricky bugs — the kind of context-heavy, multi-step work that usually requires a person to hold the thread.
The model underneath
Claude Tag runs on Claude Opus 4.8, Anthropic's current flagship model, and is described as the beginning of an evolution of Claude Code into collaborative, agentic team workflows.
Availability
Claude Tag is rolling out in beta for Claude Enterprise and Team customers today. Anthropic says it plans to bring Claude Tag to additional platforms beyond Slack in the coming weeks.
For most working professionals, the practical test is whether Claude's memory and ambient capabilities reduce the most tedious part of working with AI: the constant re-priming. If Claude Tag delivers on persistent context across channels, it moves from productivity feature to something closer to a genuine team member slot.
