Anthropic added Claude Code to Slack to automatically analyze tasks by code

Slack users now have access to Claude Code right inside work chats: now when Claude is mentioned, the assistant will automatically determine if the request is related to programming and pass it to the Claude Code module.

The feature launches today in beta in an exploratory preview format. When tagging Claude, the system analyzes the message and, if it’s a code task, uses the context of correspondence in Slack and repositories connected in the web version of Claude Code. The user can also explicitly specify that the message is a software task. This makes it possible, for example, to have Claude handle a bug report under discussion without manually submitting the data to Claude Code.

How the new extension works in Slack

The feature is built into the existing Claude app for Slack, which previously worked as a chatbot. No separate installation is required to activate the update, but you will need to set up the Claude Code web version and specify the repositories that the assistant should be able to access.

Anthropic is developing the integration on the back of the recent launch of Claude Opus 4.5. The company claims the new version outperforms Google Gemini 3 in programming tasks. However, tests have shown that Opus 4.5 rejects only 78% of malicious code requests, and security concerns remain.
