On June 23, 2026, Anthropic launched Claude Tag, a persistent AI teammate inside Slack channels for Claude Team and Enterprise customers in beta. Running on Opus 4.8, Claude Tag introduces one shared Claude identity per channel with persistent memory, ambient monitoring, agentic actions (pull requests, sales data, task management), and admin-scoped tools, data, and spending caps. Anthropic says 65% of its internal product team's code is already AI-written by the internal version. Claude Tag replaces the legacy Claude in Slack app, with a 30-day admin opt-in window and the old app phased out on August 3, 2026. The Channel Charter Doctrine gives every business owner a 5-question template to govern resident AI teammates before the deadline.
