Anthropic has unveiled a significant update to Claude Code, rebranding it as Claude Tag. This new iteration is designed to be a more proactive and team-collaboration-focused enterprise collaboration tool. At present, Claude Tag is utilized in roughly 65% of Anthropic's product code development. Karpathy highlighted that this marks the third major shift in the user interface of large language models (LLMs), with LLMs now transforming into self-contained, continuously running systems capable of seamless collaboration with human teams. The cornerstone of Claude Tag's appeal is its emphasis on team collaboration. Unlike traditional AI assistants that primarily cater to individual users, Claude Tag functions as an AI assistant shared across entire channels. This allows team members to collaborate around a single instance of Claude, eliminating the need for separate contexts. Claude Tag boasts four core capabilities: shared context, continuous memory, proactive intervention, and asynchronous execution. In proactive intervention mode, Claude actively reminds users of critical discussions, follows up on unresolved issues, and performs other relevant tasks. Its asynchronous execution feature enables users to assign tasks and step away, with Claude autonomously progressing tasks and providing proactive progress reports. Claude Tag is capable of handling tasks such as submitting or merging pull requests, conducting data analysis, and scheduling long-term projects. After integrating with Claude Code, it can further translate development requirements into actionable engineering tasks. Currently, Claude Tag is exclusively compatible with Opus 4.8 and is initially available on the Slack platform. Over the next 30 days, it will gradually supplant the existing Slack version of the Claude application, with plans to extend its availability to additional collaboration platforms in the coming weeks. In terms of privacy and permission controls, administrators have the authority to specify which tools and data Claude Tag can access, as well as the channels in which it appears. The memories and permissions of Claudes used by different teams are kept strictly separate. Additionally, administrators can set Token budgets, review operation records, and trace task initiators. At present, Claude Tag is accessible for Beta testing to Claude Enterprise and Team users.
