Anthropic Introduces Claude Tag

Claude can now be added to Slack as a full-fledged team member. Simply mention him in a message, and he will autonomously break down tasks into stages, perform the work using available tools, and publish the results directly in the discussion thread.

Claude Tag can write and merge PRs, analyze data, assist with incident resolution, and perform other tasks. In each channel, there is one shared Claude, allowing any team member to pick up where a colleague left off.

During conversations, Claude accumulates the channel's context, so he doesn't need to be re-explained the project details each time. If the ambient behavior mode is enabled, he will start to take initiative: returning to quiet discussions and reporting important events from related channels and tools.

According to Anthropic, 65% of the product department's code is already being created using the internal version of Claude Tag.

P.S. Almost immediately after the announcement, the developers of CopilotKit introduced Open Tag — an open alternative to Claude Tag. The project is compatible with any AI model, any agent framework, and custom agents, supporting generative UI, streaming response generation, Human-in-the-Loop, and full discussion thread context. Access is granted through an early access form, although the authors claim that the project is fully open and will soon open up more clients, including Telegram, WhatsApp, and Discord.
