interslack

Slack integration for Claude Code.

What this does

Send messages, read channels, and test webhook integrations from Claude Code. Uses browser session tokens (xoxc + xoxd) via slackcli, so you don't need to create a Slack app or deal with OAuth: just grab your session tokens from the browser and go.

Straightforward plumbing for when you need Claude to post updates or check channels.

Installation

First, add the interagency marketplace (one-time setup):

/plugin marketplace add mistakeknot/interagency-marketplace

Then install the plugin:

/plugin install interslack

Requires slackcli installed and configured with your Slack session tokens.

Usage

"send a message to #engineering saying the deploy is done"
"read the last 10 messages from #alerts"
"test the webhook integration"
