Install
claude plugins add slack The Slack plugin for Claude Code connects your development workflow to your team’s communication layer — posting updates, reading context, and keeping stakeholders informed without leaving the terminal.
Common uses
The most common use case is automated notifications: when Claude Code finishes a deployment, runs a test suite, or completes a long task, it posts a summary to the relevant Slack channel. This replaces the manual step of copy-pasting output into Slack.
Context retrieval
Slack is where many architectural decisions get made and documented. The search capability lets Claude retrieve past discussions before making decisions — “search #backend for the discussion about authentication approach” — so it can make choices consistent with team decisions.
Code sharing
Claude Code can post formatted code snippets, diffs, and file changes directly to Slack channels. This is useful for async code review, sharing work-in-progress, or demonstrating a proposed solution.
73,000+ installs and growing — the Slack plugin makes Claude Code a participant in your team’s workflow.
