Anthropic launches Claude Tag, an always-on Claude in Slack

Status: confirmed

Summary: Anthropic introduced Claude Tag on 2026-06-23, a way to add Claude to a Slack channel as a shared teammate. Members tag @Claude to delegate a task, which Claude breaks into stages and works through before posting the result back. An ambient mode lets Claude monitor assigned channels and intervene with summaries, reminders, or context pulled from elsewhere. One Claude instance per channel is shared across everyone in it. It is available in beta for Claude Enterprise and Team customers, with planned expansion to other surfaces.
Why it matters: It pushes autonomous, agent-style task execution into a shared team chat surface, with channel-wide visibility and ambient monitoring rather than one-to-one prompting.
Follow-up: Track general availability, data-access and permission scoping in shared channels, and rollout beyond Slack.
