Anthropic PBC, maker of the Claude family of artificial intelligence models, today introduced a feature in beta mode that lets developers delegate coding tasks to Claude Code directly inside the workplace messaging platform Slack.

Claude Code is an agentic coding tool built on Anthropic’s frontier models that helps developers turn ideas into working software. Whereas regular the Claude chatbot operates within the boundaries of a chat window, Claude Code plugs directly into a developer’s project, maintaining awareness of the entire codebase and taking actions. It can create files, refactor code, run tests and iterate autonomously. The result is a coding companion that behaves less like a chatbot and more like a junior engineer.

Now, with a Slack integration in beta for research preview, Anthropic is bringing the coding assistant closer to where developer’s work and converse.

Much of the critical context around software engineering exists in chat, where developers hash out problems and ideas together. This can include bug reports, feature requests and engineering discussions. Now, with Slack integration, developers can tag Claude Code during these conversations and have it get to work without needing to jump out of the thread.

Many developers already rely on Salesforce Inc.’s Slack, which surpassed 42 million daily active users globally in early 2025, according to a report from SQ Magazine. The computer software industry leads in usage, representing 2,118 companies actively using Slack, followed closely by information technology and services with 1,629 companies. Another report from Divilab LLC noted in 2024 that around 60% of startups pay for Slack, compared with 12% paying for Microsoft Corp.’s Teams.

This capability expands on the existing Claude app for Slack, which can now relay tasks to Claude Code on the web. Mentioning @Claude in Slack will have the AI assistant review the message to determine if it’s a coding task and route it appropriately.

A developer might simply write “@Claude fix the failing payment tests” in a channel, and Claude Code will pick up the task, investigate the error and propose a patch.

Because the app lives in Slack, the AI assistant can gather context from the conversation to better understand developer needs.

For example, a developer may discover a bug and mention it to another teammate. After a short discussion about how the bug manifests and how they found it, they might decide to have Claude Code handle the fix. In another thread, developers might riff on small feature tweaks or adjustments they’d like to see and simply tag Claude to complete them.

As Claude Code progresses in its task, it will post updates directly in the Slack thread, keeping developers in the loop. Once complete, it will link to the full session so changes can be reviewed and a pull request can be sent to update the code.
