search_doctrine
Opinions of the CADA (access to administrative documents), decisions of the Défenseur des droits, conclusions of the CE's rapporteurs publics, BOFiP (tax guidance), Code du travail numérique, CNIL deliberations. These are NOT court decisions: an opinion does not bind the judge. Keywords in French. Read a document: get_decision(id=…). For conclusions (ariane_crp), the case number is `numero`; `doc_id` is an internal identifier. Example: search_doctrine(query="communication dossier médical", source="cada")

}get_law_article
Article of a French code or statute, as in force on a date (default: today). `code`: abbreviation ("CT", "cc"), name ("code du travail"), LEGITEXT or statute ("loi 91-647", "loi du 1er juillet 1901"); list: about(topic="codes"). European texts: "CEDH" (protocols: num="P1-1"), "CHARTE_UE", "TUE", "TFUE"; treaties: "CIDE", "GENEVE1951", "HAYE1980"… (with French status); EU acts: "RGPD", "directive 93/13", "UE-<CELEX>" (repealed: flagged). To cite an older decision, pass its date: the article is served as it stood then. `view="versions"`: its history; `view="map"`: wordings, citing texts, implementing orders. `etat`/`note` flag a lag behind Légifrance; `info_numero`, a renumbering. `num` also accepts a LEGIARTI (`code` may then be omitted). Without `num`, a LEGITEXT (outside codes), a European text or a treaty gives the whole text, 120 articles per page (`suite`: offset=…). Examples: get_law_article(code="CIDE", num="3"); get_law_article(code="code civil", num="1382", date="2015-06-01")

}search
Searches all sources (French and European case law, codes and statutes, Journal officiel, collective agreements, doctrine), expanding to legal synonyms. Entry point for an open question; for one specific court, use `search_case_law`. A citation ("Cass. soc. 11 mai 2022", an ECLI, an appeal number) is recognised and searched as such. Singular and plural are searched together; "in double quotes": the exact word. Query in French: the data is French (some ECHR/CJEU texts are English only). Example: search(query="harcèlement moral fonctionnaire") Args: query: keywords or a citation; OR/AND/NOT/NEAR in UPPERCASE between two words are operators (NEAR = within 10 words); lowercase words are plain words sources: dila, jade, legi, cedh, cjue, kali, jorf, doctrine (empty: all) sort: relevance | date_desc | date_asc date_min: YYYY-MM-DD (all sources) date_max: YYYY-MM-DD limit: results (max 100) expand_synonyms: expand to legal synonyms (default true)

}delete_account_item
Permanently deletes one object of the user's JusticeLibre account: a case file (with all its content), a saved reference, a subfolder, a note, or an AI skill proposal not yet activated (`skill`, id s_… or p_…). No recycle bin. confirm=true states the user's explicit agreement; without it, nothing is deleted. Permission supprimer; a reference the AI saved itself can also be removed with permission notes_ia. To keep a trace with a reason instead: update_account_item with set_aside. Requires a JusticeLibre account (OAuth sign-in). Example: delete_account_item(what="note", id="n_…", confirm=true)

}check_citations
Finds where a quoted passage comes from (paste the quotation alone, ≤ 3,000 characters, original language). Check each result against the source (link provided). Returns texts and decisions containing it, with a match % (100 = word for word, ignoring punctuation, case, accents) and word differences. Statuses: trouve; trouve_avec_differences; non_trouve (database may be incomplete); trop_court; trop_courant; indetermine (sources timed out: retry). `textes_d_origine` = statutory sources; `repris_dans` = decisions quoting it; otherwise `decisions`, oldest first. Covers codes and statutes (`version_du`), JO, collective agreements, all French case law, ECHR, CJEU, CNIL, doctrine, professional codes, EU acts in force (`note_textes_europeens`). Article references in the text are listed, unchecked, with their get_law_article call.
