I am building a new developer tool for managing database migrations via terminal. Can you help me design the command structure and output formats for the status and apply commands? Please provide a recommended command layout along with example terminal outputs for standard success and error scenarios.

What's inside

The instructions your model reads when the skill loads.

SKILL.md9 linessingle file

CLI Design Skill

Use this skill when writing new CLI commands, reviewing CLI code, or fixing inconsistencies.

Key Principles

Atomic Command — each command does one operation, agents compose them freely
TTY & Non-TTY — every command works in both interactive and programmatic modes
Guided Flow — output always guides to the next action (success → next step, error → remediation, empty → creation)
