CLI Overview

The s9 command-line tool is the primary interface for interacting with site-nine. It provides commands for managing missions, tasks, epics, reviews, and more.

Installation

If you have site-nine installed, the s9 command should be available in your PATH:

s9 --version

Getting Help

s9 --help              # Show all available commands
s9 <command> --help    # Show help for a specific command

Command Audience Guide

The s9 CLI is designed to serve two primary audiences:

  • Human developers use s9 for project oversight, planning, and coordination (creating tasks, reviewing work, managing epics, viewing dashboards)
  • AI agents use s9 for automated workflows (starting missions, claiming tasks, creating handoffs, updating status)

Some commands are useful to both audiences (like viewing task details or listing missions), while others are optimized for one or the other.

Where to Go Next

Each command's help text includes a "typically used by" indicator to help you understand its primary audience.
