Anthropic launches Claude Tag, a Slack teammate that already writes 65% of its product team's code

Claude Tag is Anthropic's new Slack-native agent that teams delegate work to by tagging @Claude, and it already writes 65% of Anthropic's own product-team code. On June 23, 2026, Anthropic launched Claude Tag in beta as a way to delegate work directly inside Slack. Anthropic's own product team already writes 65% of its code with an internal version, the agent runs on Opus 4.8 and remembers per-channel context, and it opens first to Claude Enterprise and Team customers. ASAP summarizes the announcement from the primary source.

The number that came from internal dogfooding: 65% of code

Anthropic's product team writes 65% of its code with the internal Claude Tag version, the company says. Claude Tag runs on Opus 4.8 and builds context over time, so it does not need repeated explanations to keep working. Instead of answering a single question, it plans and completes delegated tasks on its own. What makes the 65% figure stand out is that it goes beyond autocomplete-level help: whole units of work are handed off.

One @Claude tag hands off the work

Claude Tag joins a Slack channel as a team member and is called with the @Claude tag. It is multiplayer, so within a given channel there is one Claude that interacts with everyone, and it builds context once users grant access to channels, tools, data, and codebases. With "ambient" behavior enabled, it flags relevant information and follows up on unresolved tasks. It is less a bot waiting for commands than a participant that reads the flow of a conversation and steps in on its own.

The channel becomes the boundary line for memory and cost

Administrators control access to sensitive data and tools by channel, creating separate Claude identities for different uses. Sales and engineering instances do not share information, and memories and data stay scoped to the defined channels. Administrators can set monthly spend limits at both organization and channel levels. In effect, the channel doubles as both the access boundary and the budget boundary.

The order the doors open: Enterprise and Team first, existing users get 30 days

Claude Tag started its beta on June 23, 2026 for Claude Enterprise and Team customers. Existing "Claude in Slack" users have 30 days to opt in, and eligible Enterprise and Team organizations receive launch credits. Anthropic says it aims to expand beyond Slack to other platforms.

Why it matters: from answer tool to async teammate

Claude Tag is a sign that AI is shifting from answering one-off questions to being an async teammate that builds context and schedules its own work. Until now, AI tools have been trapped in the immediacy of a query-and-response loop. A design that lives in the channel and chases down unfinished tasks reads less like a request desk and more like a declaration that AI should be treated as staff attached to a project. If this shift takes hold, the center of gravity in collaboration tools moves from human-to-human conversation toward human-to-agent delegation.

How to read this number

The 65% figure comes from internal dogfooding, so results may differ in other environments. It is a score the team that built the tool posted on its own codebase, so there is no guarantee the same ratio holds on unfamiliar legacy code or in tightly regulated code. That makes the per-channel controls on permissions and cost just as important as the capability itself, because the wider the delegation, the greater the fallout from a bad access grant or runaway spend. For companies in Korea, the isolation model that keeps internal data from leaking outside a channel is likely to be the first gate that decides whether to adopt it.
