Learn how to add Claude Code to Slack and use it to fix bugs or implement new features without opening a code editor. By the end, you’ll have a Slack-based workflow for assigning coding work to Claude Code from a channel or thread.
You’ll set up Claude Code inside Slack so you can assign coding tasks from Slack, including from the mobile app.
Add the URL or name of the relevant GitHub repository to the channel details so Claude always picks the correct project.
Connect Claude Code to your GitHub account.
Add the Claude app to your Slack workspace.
After it appears in Slack, click “Connect Account” and give Claude access to Slack.
By default, the app will be set to “code only” mode. You can switch to “Code + Chat” if you still want to use Claude like an AI assistant in your workspace. You might do this if you have Claude connected to other services like Notion or Google Drive.
Claude Code will not work if you mention it in a direct message. It must be used in a Slack channel. Add Claude to an existing channel, or create a dedicated channel for coding tasks.
You can now @Claude and give it coding tasks. Claude will build context based on recent messages, and it works best if you start a thread on a particular issue.
As a bonus, you can now access Claude Code from your phone through the Slack app.
As a next project, ask Claude to write a single-page HTML file. In the source example, Claude created a simple galaxy animation.
