The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_judgment ~150
Pobiera pelne orzeczenie z SAOS po jego numerycznym ID. Zwraca metadane (sygnatura, sad, data, sklad, podstawy prawne), streszczenie (jesli dostepne) oraz pierwsze 2000 znakow tresci. ID orzeczenia pochodzi z wynikow narzedzia 'search' lub 'search_by_case'. Bledy: `missing_arg` (brak id), `not_found` (id poza baza), `upstream_error`.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string|number | yes | Numeryczne ID orzeczenia w bazie SAOS, np. 352475 lub '31345'. |

saos_cite_check ~447
Citator 'czy wyrok zyje': dla podanej sygnatury szuka POZNIEJSZYCH orzeczen, ktore ja cytuja (pelnotekstowo w SAOS), i skanuje ich uzasadnienia pod frazy przelamania linii orzeczniczej (np. 'odstepuje od pogladu wyrazonego', 'nie podziela pogladu', 'traci moc uchwala', 'uchwala skladu siedmiu sedziow') w oknie ~500 znakow wokol wystapienia sygnatury. Werdykt: przelamanie_wykryte / uchwala_skladu_powiekszonego / nadal_cytowany / brak_cytowan_w_saos. To heurystyka - kazde trafienie ma fragment tekstu do recznej weryfikacji, a brak trafien NIE potwierdza aktualnosci orzeczenia. Bledy: `missing_arg` (nieczytelna sygnatura), `invalid_court_type`, `upstream_error`.
| Name | Type | Req | Description |
|---|---|---|---|
| caseNumber | string | yes | Sygnatura akt orzeczenia do sprawdzenia, np. 'III CZP 6/21'. Moze byc czescia zdania ('uchwala SN z 7.05.2021 r., III CZP 6/21'). |
| courtType | string | – | Opcjonalnie: typ sadu orzeczenia badanego - sygnatury powtarzaja sie miedzy sadami, to doprecyzowuje ktore orzeczenie sprawdzamy. |
| deepScan | boolean | – | Czy pobierac pelne teksty cytujacych orzeczen (domyslnie true). false = tylko szybki skan snippetow z wyszukiwarki. |
| maxScan | number | – | Ile cytujacych orzeczen przeskanowac w pelnym tekscie (1-20, domyslnie 8). Priorytet: SN > uchwaly > najnowsze. |

search ~514
Przeszukuje baze orzeczen sadow polskich w SAOS (System Analizy Orzeczen Sadowych). Pokrycie obejmuje takze orzeczenia biezace (lata 2024-2026 sa dobrze reprezentowane), ale jest nierowne wg typu sadu. Sady administracyjne (WSA/NSA) NIE sa indeksowane. Daty bywaja znieksztalcone przez OCR - weryfikuj sygnature i date w zrodle. Przydatny do: analizy linii orzeczniczej, precedensow, wyszukiwania po tresci / sygnatuze / sedzim / podstawie prawnej. Bledy: `invalid_court_type` (zly enum), `upstream_error` (HTTP/timeout API).
| Name | Type | Req | Description |
|---|---|---|---|
| all | string | – | Wyszukiwanie pelnotekstowe - slowo lub fraza w tresci orzeczenia. |
| caseNumber | string | – | Sygnatura akt, np. 'I ACa 772/13' lub 'IV CSK 123/15'. |
| courtType | string | – | Typ sadu: COMMON=sady powszechne, SUPREME=Sad Najwyzszy, CONSTITUTIONAL_TRIBUNAL=Trybunal Konstytucyjny, NATIONAL_APPEAL_CHAMBER=Krajowa Izba Odwolawcza (KIO). NIE uzywaj ADMINISTRATIVE - sady admin… |
| dateFrom | string | – | Data orzeczenia od (format YYYY-MM-DD), np. '2015-01-01'. |
| dateTo | string | – | Data orzeczenia do (format YYYY-MM-DD), np. '2016-12-31'. |
| judgeName | string | – | Nazwisko sedziego, np. 'Kowalski'. |
| legalBase | string | – | Podstawa prawna, np. 'art. 415 kc' lub 'art. 6 RODO'. |

search_by_case ~155
Skrot: szuka orzeczenia po sygnaturze akt (np. 'I ACa 772/13', 'IV CSK 123/15', 'KIO/UZP 100/12'). Odpowiednik search z parametrem caseNumber. Jesli sygnatura nie znajdzie sie w SAOS, sprawa moze byc z sadu administracyjnego (WSA/NSA - nieindeksowane) lub jeszcze nieopublikowana w bazie. Bledy: `missing_arg` (brak caseNumber), `upstream_error`.
