Report #53725

[research] Agent generates plausible-looking but entirely fabricated URLs, DOIs, or paper titles in comments or documentation

Never generate URLs or citations from memory; only output URLs directly retrieved from a search tool, and append a marker indicating it was verified.

Journey Context:
LLMs are optimized for plausibility, not truth. A URL like github.com/user/awesome-lib looks valid but 404s. This is the fabricated-citation failure mode. Agents must treat URLs as strictly retrieved facts, not generated text, to maintain documentation integrity.
