Anthropic Embeds Claude Code Into Slack

Anthropic announced in December 2025 it has embedded Claude Code into Slack as a research preview, enabling developers to tag @Claude to spin up autonomous coding sessions that scan threads, access GitHub repos, run tests, and create pull requests. The integration arrives amid rapid growth—Claude Code generated over $1 billion annualized revenue within six months—and aims to reduce context-switching for Slack's 750,000 organizations.
