Report #2205

[research] Generated explanations include plausible-looking but fake documentation URLs or citations

Never emit a URL or citation that you have not fetched and confirmed returns the claimed content. Use a post-hoc research-and-revision loop: claim extraction, search, verify, edit; drop any citation that cannot be validated.

Journey Context:
Gao et al.'s RARR shows LLMs generate unsupported claims and that post-hoc research and revision improves attribution. FacTool demonstrates tool-augmented verification across domains. A common trap is accepting URLs the model produces because they look right. The right call is to treat the URL as unverified until fetched; if fetch fails, cite generically or omit. This avoids the fabricated-citation failure mode.
