Report #97963

[research] Agent is not tested on realistic hallucination failure modes, so hallucination rate is unknown.

Evaluate on dedicated hallucination benchmarks such as HaluEval, TruthfulQA, and FActScore; report hallucination rate and fact-level precision, not just task accuracy.

Journey Context:
Li et al.'s HaluEval provides 35,000\+ examples spanning QA, dialogue, and summarization, revealing that models hallucinate in all three settings. Task accuracy can hide factuality problems because a partially wrong answer may still look acceptable. A coding agent should measure whether its outputs are grounded, not just whether they appear helpful.
