When tagged, Claude will automatically examine the message for coding tasks and forward them to Claude Code, utilizing context from the associated Slack thread and the validated code repositories in Claude Code. Users can also directly instruct Claude that a request pertains to a coding issue. For example, you might ask Claude to analyze a reported bug you are discussing in Slack without needing to manually transfer all contextual information into Claude Code.
This new functionality is part of the already existing Claude app for Slack, which previously functioned as an in-app chatbot. There’s no necessity to download additional software if you already possess it, but you must have the web version of Claude Code configured with the code repositories you intend to utilize.
The introduction of this feature in the Claude Slack app comes shortly after Anthropic released its new Claude Opus 4.5 model. Anthropic asserts that the newest iteration of Claude outperforms Google Gemini 3 — whose impressive benchmarks shook the industry upon its introduction — specifically in coding tasks, although it still encounters certain safety and security challenges. For example, early assessments revealed that Opus 4.5 only denied 78 percent of requests to generate malware and other harmful code.
