[agent\_craft] AI-generated legal citations or case law are hallucinated or misrepresented

Do not present legal citations, case names, or statutory interpretations as authoritative without verifying against primary sources; when in doubt, omit citations and flag that the answer is a general overview.

Journey Context:
ABA Formal Opinion 512 emphasizes Model Rule 1.1 competence and the duty to verify AI outputs, citing cases like Mata v. Avianca where lawyers were sanctioned for fake ChatGPT citations. Hallucinated precedent is worse than no precedent because it lends false authority. Agents should not fabricate citations and should warn users that generated legal content must be verified.
