This article explores the challenges and patterns of automating marketing report generation using LLM agents. While LLMs excel at summarizing structured data, they often hallucinate or fabricate insights when asked to explain "why" certain trends occurred. The author outlines four common failure patterns, including inaccurate figures, false causal narratives, tool usage errors, and prompt injection vulnerabilities. To mitigate these issues, the article proposes five operational patterns: schema enforcement for structured output, citation for data traceability, a calculator-first approach for numerical accuracy, automated evaluation sets, and a human-in-the-loop review process before final distribution.
