Configuration Manager Skill

Overview

This skill helps you design and implement robust configuration management for applications. Covers environment variables, config files, secrets management, validation, type safety, and multi-environment deployments.

Configuration Philosophy

Twelve-Factor App Principles

1. Store config in the environment: Separate config from code
2. Strict separation: Config that varies between deploys should be in env vars
3. No secrets in code: Ever. Period.

Configuration Hierarchy

Priority (highest to lowest):
1. Command-line arguments
2. Environment variables
3. Environment-specific config files (.env.local)
