Slack users can now access Anthropic’s Cloud Code directly in Slack by tagging the Cloud on coding-related messages and threads. there is a new feature Launching in beta today As a research preview.
When Cloud is tagged, it will automatically scan the message to see if it is a coding task and, if so, route it to Cloud Code using the corresponding Slack thread and a reference to the code repository you authenticated in Cloud Code. Slack users can also directly tell the cloud that the request is a coding task. For example, you can ask the cloud to investigate a bug report you’re discussing in Slack, without manually copying all the references into the cloud code.
The new feature is part of the existing Cloud app for SlackWhich earlier worked as an in-app chatbot. So if you already have anything new there is no need to download it, but you will need Web version of Cloud Code Set up with the code repositories you want to use.
This expansion of the cloud Slack app comes just weeks after Anthropic launched its new Cloud Opus 4.5 model. Anthropic claims that the latest version of the cloud surpasses Google Gemini 3 – whose overall higher benchmarks had the industry nervous around its release – especially in coding, but it still faces some safety and security issues. For example, early tests showed that Opus 4.5 rejected only 78 percent of requests creating malware and other malicious code.
