Can I automate the config update process?

Yes, the skill provides patterns for writing idempotent Python migration scripts that create backups and programmatically transform YAML files to the new schema format.

How does this handle legacy configuration files?

It utilizes Pydantic's model_post_init and Optional fields to create a bridge between legacy keys and new sections, issuing clear deprecation warnings to users rather than breaking the application.

What is a discriminated union in this context?

It allows a single configuration block to support multiple distinct model types (such as switching between a CLI and HTTP adapter) based on a specific 'type' field.

Does it support secret management?

Yes, it implements a regex-based resolver within Pydantic field validators to automatically substitute ${VAR_NAME} syntax with actual environment variables at runtime.

Evolves Pydantic configuration schemas with automated migration scripts and backward compatibility.

The Config Schema Migrator skill provides a comprehensive framework for managing the evolution of application configurations using Pydantic. It enables developers to modify schemas—such as adding sections, changing field types, or restructuring data—without breaking existing installations or manual configuration files. By implementing best practices like deprecation warnings, environment variable substitution, and type-safe discriminated unions, this skill ensures that configuration management remains robust, secure, and developer-friendly throughout the software lifecycle.
