Rainer Friederich enhanced the adobe/spacecat-api-service repository by adding UUID primary keys to prompts, topics, and categories in the V2 Prompts API, using JavaScript and YAML to update both the API implementation and the OpenAPI specification. This change enabled direct foreign key wiring to brand_presence_executions, reducing the need for downstream database lookups and improving data retrieval efficiency. Rainer ensured backward compatibility by preserving existing TEXT business keys and coordinated deployment with dependent services to maintain data integrity. Comprehensive testing and validation, including over six thousand passing tests and clean ESLint results, demonstrated a thorough and reliable engineering approach throughout the project.
