Your AI agent can read your repo, run your tests, and open a pull request. Then it hits a wall. The context it needs is in Slack: the incident thread, the decision nobody wrote down, the "we changed the deploy order last week" message.

SlackCLI is a single open source binary that allows an AI agent to access Slack without the need for a Slack app or OAuth scopes. It is a CLI tool that communicates with Slack from the terminal and speaks JSON. Once the agent is authenticated using a single command, it can perform various tasks such as reading unread conversations, reading threads, searching the workspace history, replying in conversations, posting reports in markdown, reading canvases as markdown, and sending messages.
These commands can be executed with just a few simple instructions, making it an efficient and easy-to-use tool for AI agents. The tool maintains security by not sharing credentials and allowing for separate identities for automation purposes. It is written in Bun and supports multiple platforms, with over 400 tests and a comprehensive user guide.
