Slack users can now access Anthropic’s Claude Code directly in Slack by tagging Claude on coding-related messages and threads. The new feature is launching today in beta as a research preview.
When Claude is tagged, it will now automatically scan the message to see if it’s a coding task and, if so, route it to Claude Code using the context from the related Slack thread and the code repositories you’ve authenticated in Claude Code. Slack users can also directly tell Claude that a request is a coding task. For instance, you could ask Claude to investigate a bug report you’re discussing in Slack without needing to manually copy all the context into Claude Code.
The new feature is part of the existing Claude app for Slack, which previously acted as an in-app chatbot. So there’s no need to download anything new if you already have it, but you’ll need to have the web version of Claude Code set up with the code repositories you want to use.
This expansion of the Claude Slack app arrives just a few weeks after Anthropic launched its new Claude Opus 4.5 model. Anthropic claims the latest version of Claude surpasses Google Gemini 3 — whose overall high benchmarks rattled the industry around its release — in coding specifically, but it’s still facing some safety and security issues. For instance, early tests showed Opus 4.5 only refused 78 percent of requests to create malware and other malicious code.
