Config Schema Migrator

关于

The Config Schema Migrator skill empowers Claude to handle complex configuration lifecycle management within Python projects. It specializes in evolving Pydantic models through field additions, type changes, and structural refactoring while ensuring existing user configurations remain functional. By implementing patterns for deprecation warnings, environment variable substitution, and automated migration scripts, it simplifies the process of maintaining robust, type-safe application settings as software matures and requirements change.
