        "longDescription": "LexAgent gives ChatGPT the official texts of Dutch and EU law, so answers rest on the source instead of memory.\n\nIt reads, straight from the government open-data services:\n- National legislation from wetten.overheid.nl, article by article and for any date (peildatum).\n- Local regulations of municipalities, provinces and water boards (APVs, verordeningen, omgevingsverordeningen).\n- Official publications: Staatsblad, Staatscourant, Gemeenteblad and parliamentary papers.\n- Dutch case law from Rechtspraak, by ECLI, court, area of law and date.\n- EU legislation and treaty articles from EUR-Lex, including consolidated versions and the Dutch implementing measures.\n- Case law of the Court of Justice of the EU, down to the numbered point, and Advocate General opinions.\n- Council information: proposals, motions with votes, decision lists and minutes of Dutch councils.\n\nEvery document comes with a citation (article, ECLI or CELEX, version date) and a link to the official source. Two skills guide the work: Dutch legal research, and checking the legal claims in a document against the sources.\n\nLexAgent is read-only: it never changes anything at the sources or in your account. It provides legal information from public sources, not legal advice. A LexAgent account is required.",
