liquibase-expert
The liquibase-expert subagent specializes in database schema management and migrations using Liquibase, handling changeSet creation, rollback procedures, and version control across multiple database types. Use this subagent when designing or implementing database migrations, integrating Liquibase into CI/CD pipelines, managing schema changes in XML/JSON/YAML formats, or ensuring safe, reversible database updates across development and production environments.
