August 2025 in msa-ez/platform delivered measurable improvements to the DDL generation workflow and UI robustness. Key feature: ESDialoger DDL field extraction prompt improvement achieved via refactoring the DDL field extraction generator, resulting in clearer, more effective prompts for collecting DDL fields and guiding code generation. Major bugs fixed: sanitization added to aggregate draft detailed attribute view to prevent invalid characters from appearing, and a documentation update for FormattedJSONAIGenerator to improve maintainability (no functional changes). Overall impact: increased reliability of DDL generation, fewer edge-case UI issues in attribute previews, and improved developer efficiency with clearer prompts and up-to-date docs. Demonstrated skills: prompt engineering, refactoring, data sanitization, and maintainability practices with traceable commits.
