An article discusses the dangers of AI agents inventing database columns, a phenomenon known as 'invented column.' This occurs when an AI model fabricates plausible column names that do not exist in the actual database schema, leading to errors in generated SQL queries. The author highlights that these invented columns are particularly insidious because they appear syntactically correct and conventionally named, making them difficult to detect. Current solutions like improved prompts, schema exports, and live database catalogs have limitations, such as prompts being forgotten, schemas becoming stale, and context window limits. The proposed solution involves using an 'approved version' of the schema stored in a designer tool, which acts as a contract between developers and the AI agent, eliminating the need for direct database credentials and ensuring the agent uses up-to-date, semantically rich information.
