Context

Ground Control needs a CLI tool for administrators to manage satellites, groups, and configs without using the REST API directly.

Current State

• GC only accessible via REST API
• No official CLI tool
• Users must use curl or write custom scripts

Expected Behavior

CLI binary gcctl with:

• gcctl login - authenticate and store session
• gcctl logout - clear session
• gcctl whoami - show current user

Config stored at ~/.gcctl/config.yaml:

server: https://gc.example.com
token: <session-token>

Features:

• Tab completion (bash/zsh)
• Multiple output formats (table, json, yaml)
• Config file for default server

Value

• Easier administration
• Scriptable operations
• Better developer experience

Changes to be Made

• Create CLI skeleton with cobra
• Implement login command
• Implement logout command
• Implement whoami command
• Config file management
• Tab completion generation
