search_corpus

The full ranked search over statutes, case law, Rechtssaetze, literature and legislative materials in one jurisdiction. This is the same engine the web app runs, not a keyword match: a norm citation (§ 543 BGB), an ECLI, a Geschaeftszahl or an RS number inside q is resolved and pinned to the head of the list, and a pinned norm also brings the top decisions applying it, each marked chainOf. In lexical mode q supports UND / ODER / NICHT, quoted phrases, wildcards (Haus*) and citations as boolean operands, so BRAO UND Cloud means "documents citing the BRAO that mention Cloud".

tiers scopes the search, and its presets replace what used to be separate tools (search_decisions / search_rechtssaetze, removed 2026-08-08): tiers: ["case_law"] is the decisions-only search (Entscheidungen — court practice, where statute text alone will not answer; read hits with get_decision), and tiers: ["rechtssatz"] searches only Rechtssätze. A Rechtssatz (plural Rechtssätze) is an officially distilled headnote with a stable RS number, published by the court itself, for example by the Austrian OGH. In Austrian research this is the primary entry point, because the corpus is rechtssatz-driven: find the headnote, then follow document_relations along abstracted_from into its decision chain, and read it in full with get_rechtssatz.

To narrow before spending a ranked search, call refine_search — it returns counts and facet rails and never buys an embedding.

Parameter	Type		Notes
q	string	required	Query; lexical mode supports UND / ODER / NICHT
jurisdiction	DE|EU|AT	required	Corpora are never mixed
mode	hybrid|semantic|lexical	optional	Default hybrid. Semantic embeds the raw text, so boolean operators are inert there and the response discloses it.
tiers	array of search tier	optional	statute, case_law, rechtssatz, literature, admin_publication; omit for all of them. ["case_law"] = decisions only, ["rechtssatz"] = headnotes only (the primary Austrian entry point)
type	search tier	optional	Deprecated single-tier form of tiers; folded into it
courts	array of court key	optional	Enum-constrained: de-bgh, de-olg, ogh, bvwg and the rest. A restrictive court filter also narrows the search to the court tiers and says so in warnings.
from	YYYY-MM-DD	optional	Earliest document date, inclusive
to	YYYY-MM-DD	optional	Latest document date, inclusive
decisionTypes	array of string	optional	Entscheidungsart subset, verbatim source values. Not an enum: the vocabulary is the source's and lives in the corpus. Get it from describe_filters.
indexGroups	array of string	optional	RIS Index (Sachgebiet) keys, Austrian only. Coverage is partial: sources that publish no Index are excluded outright, and the response says so in warnings.
limit	integer 1-50	optional	Default 8
offset	integer 0-199	optional	Follow paging.nextOffset; never compute offset + limit yourself. offset + limit may not exceed 200.
sort	relevanz|datum-desc|datum-asc	optional	Default relevanz

Output

structuredContent.hits[], each with uri, url (a deep link into the web app), tier, documentDate, heading, fragmentId, score, snippet, and the structural markers pinned, browse, chainOf and citationCount where they apply. Beside the hits, the honesty envelope described under Reading the search envelope.

refine_search

Counts and facet rails for a query plus filters — how many documents match, and how those matches distribute across tiers, court categories, Entscheidungsarten and, for Austria, RIS Index groups. This is the narrowing tool: call it repeatedly to decide what to filter on, then call search_corpus once for the actual page.

It returns no hits and takes no mode, because counting is always the lexical reading of the query. That is a cost decision, not a convenience: there is no argument a caller can pass that turns this tool into a paid embedding, so a narrowing loop of any length costs nothing per step. Every facet bucket's key is exactly what to pass back as courts, decisionTypes, indexGroups or tiers.

What it measures is not what search_corpus runs. This is a term-matching probe; search_corpus defaults to hybrid and also ranks by meaning, so its list can contain — and rank highly — documents this count never saw. Measured on one Austrian query: the rail reported rechtssatz: 1 while four Rechtssätze sat in the hybrid top ten. Read every number here as a floor and a shape, never as an inventory, and never conclude a tier is empty because its rail is thin. Declare your intended next mode in followUpMode and the response states the mismatch in countedAs, in structured form and in the text mirror.

Pass keywords, not a sentence. q is read as a conjunction: every term must occur in the same document, so a pasted question requires all of its words, hat and das included. Measured: 2 matches for a lawyer's question, 225 for the same question reduced to its decisive terms. When the engine sees that shape it says so in warnings — it never rewrites the query, because answering a different question quietly is the same defect one layer down.

Parameter	Type		Notes
q	string	required	Read lexically; UND / ODER / NICHT apply
jurisdiction	DE|EU|AT	required	Corpora are never mixed
tiers	array of search tier	optional	Restrict the counted population
courts	array of court key	optional	Enum-constrained: de-bgh, de-olg, ogh, bvwg and the rest. A restrictive court filter also narrows the search to the court tiers and says so in warnings.
from	YYYY-MM-DD	optional	Earliest document date, inclusive
to	YYYY-MM-DD	optional	Latest document date, inclusive
decisionTypes	array of string	optional	Entscheidungsart subset, verbatim source values. Not an enum: the vocabulary is the source's and lives in the corpus. Get it from describe_filters.
indexGroups	array of string	optional	RIS Index (Sachgebiet) keys, Austrian only. Coverage is partial: sources that publish no Index are excluded outright, and the response says so in warnings.
followUpMode	hybrid|semantic|lexical	optional	The mode you intend to run next (default hybrid). Disclosure only: it never reaches the engine and cannot change what this call does or costs.
facets	boolean	optional	Default true; false returns the total only

Output

total, the same interpretation envelope (residual, parsed, warnings, applied), and facets with tiers, courts, decisionTypes, indexGroups, approximate, cappedAt and indexGroupCoverage. approximate: true means the counts came from a capped scan and are a disclosed estimate. countedAs states what was measured (mode: "lexical", embedding: false), your declared followUpMode, and mismatch: true when the two differ.

{"name":"refine_search",
 "arguments":{"q":"Eigenbedarfskuendigung","jurisdiction":"DE","tiers":["case_law"]}}

describe_filters

The values the search filters accept, for one jurisdiction. Call it before filtering on anything you did not read out of a refine_search facet: an invented Entscheidungsart or Index group matches nothing and returns a confidently empty result set.

courts, tiers, sorts and modes are also enforced as enums in the tool schemas, so a model cannot emit an invalid one in the first place; they are repeated here with their German labels. decisionTypes and indexGroups exist only here, because they are the source's vocabularies, they live in the corpus, and the Index alone runs to several thousand values — far too many to ship in every tools/list; the response's own coverage block carries the live count.

Parameter	Type		Notes
jurisdiction	DE|EU|AT	required	Vocabularies are per jurisdiction
dimension	courts|tiers|sorts|modes|decisionTypes|indexGroups|paging	optional	Fetch one dimension only; omit for all of them
contains	string	optional	Case-insensitive substring filter for decisionTypes / indexGroups — search a long vocabulary instead of paging it
limit	integer 1-500	optional	Max Index buckets, default 25; the cut is disclosed as shown vs total

Output

courts[] (key, German label and held, the number of that court's decisions the corpus holds — 0 means a filter on it returns nothing), tiers, sorts, modes, paging (limitMax, windowCap and why the window is capped), decisionTypes with live counts, and indexGroups with total, shown, per-group counts and the coverage disclosure naming which sources publish an Index and which an Index filter would exclude entirely.

get_norm_dossier

One aggregate read that answers "what do I need to know about § 543 BGB": the current provision text, the version timeline (Fassungen), the decisions applying it ranked by their own authority and grouped by court level, the Rechtssaetze attached through the source-published relation mesh, and the Drucksachen passages citing it (Gesetzesbegruendung).

Prefer it over hand-walking get_provision, get_provision_history, citation_neighbors, document_relations and browse_documents: it is one call instead of five, and the joins are done for you. Reach for the narrower tools when you need a point-in-time text (get_provision with lawAsOf), a text diff, or the mesh around a decision rather than a norm.

Parameter	Type		Notes
resource	string	required	Statute id, e.g. bgb
num	string	required	Provision key: 543, art/7, or the nested art/17/sec/2. Same grammar as get_provision, including the art/<n> → sec/<n> resolution for acts whose source publishes no per-provision type
jurisdiction	DE|EU|AT	required	Corpora are never mixed
limit	integer 1-100	optional	Rows per list section, default 10
sections	array of provision|versions|applying|rechtssaetze|materialien	optional	Return only these sections; omit for all of them

Output

provision, law, versions, applying (with total, shown, capped and truncated), rechtssaetze and materialien. applying.capped: true means a scan cap truncated the candidate pool, so the rows are the most-cited slice rather than the whole set. Each decision's applies distinguishes a source-published relation from a derived text mention, and citationCount is the decision's own authority — there is deliberately no authority score for the norm.

{"name":"get_norm_dossier",
 "arguments":{"resource":"bgb","num":"543","jurisdiction":"DE","limit":5}}

resolve_law

Turn a statute's Kurztitel or abbreviation (AngG), its full title (Angestelltengesetz) or its id into the resource id that get_provision, get_provision_history and get_norm_dossier take. Use it instead of guessing an id, instead of paging list_laws (18,294 statutes for AT, 366 pages), and instead of browse_documents: browsing is a ranking, and a ranking answers a resolution question wrongly in the one way nothing downstream can detect.

Matching is exact and case-insensitive against the Kurztitel, the full title and the id. There is no fuzzy arm, so a content word never becomes a law. Beyond the corpus's own names, the resolver consults the same hand-verified alias table the citation pin uses (matchedOn: "alias" — GewO 1859 resolves to at-br-20002842, whose corpus Kurztitel is a bare Gesetzesnummer), and a name carrying a consolidation year resolves when the act asserts that year in its own name (matchedOn: "nameYear" — two agreeing witnesses, e.g. AVG 1991).

Read status, not candidates[0]. resolved hands over one resource. ambiguous means several laws claim the name — roughly 312 Austrian abbreviations collide, usually a federal act beside a provincial one (SPG, EMRK, StAG, RPG) — and then resource is null and nothing is chosen for you. not_found may carry suggestions: prefix hits from the act typeahead, or holders of the name whose own names could not confirm a cited year — a next step and never an answer. A year that every holder contradicts (AVG 1950) is a refusal, and note names the declined Fassung in the payload and in the text mirror — the corpus does not hold that consolidation.

Parameter	Type		Notes
shortTitle	string	required	Kurztitel, full title or resource id. Matched exactly — no substring, no similarity.
jurisdiction	DE｜EU｜AT	required	Corpora are never mixed, and the same abbreviation means different acts in different ones.

Output

status (resolved | ambiguous | not_found), resource (set only when resolved), candidates[] with resource, shortTitle, title, jurisdiction and matchedOn, capped, suggestions[] and a German note. The same answer is served over REST at GET /laws/resolve.

{"name":"resolve_law","arguments":{"shortTitle":"AngG","jurisdiction":"AT"}}

→ EINDEUTIG (status resolved): at-br-10008069 — AngG (Angestelltengesetz) [AT, gefunden über shortTitle]

{"name":"resolve_law","arguments":{"shortTitle":"SPG","jurisdiction":"AT"}}

→ MEHRDEUTIG (status ambiguous) — 3 Gesetze tragen „SPG“ in AT. NICHT aufgelöst; nicht die erste Zeile wählen.

list_laws

Enumerate the statutes held in one jurisdiction: a bounded page of resource ids with their short and full titles, plus total, so a caller learns how large the corpus is without receiving it. Use it to survey what is held, or to page a filtered slice.

To look up a law you can already name, call resolve_law instead. AT holds 18,294 statutes and EU 26,285; enumerating them to find one abbreviation is 366 pages against one exact call. The unbounded shape this replaced returned every row twice — once as structuredContent and once as the text mirror, 4.47 MB for AT in a single tool result.

Parameter	Type		Notes
jurisdiction	DE｜EU｜AT	required	Corpora are never mixed
q	string		Case-insensitive substring of the Kurztitel or full title. It shortens a list; it does not identify a law. A substring hit is not a resolution.
limit	integer		Rows per page, default 50, max 500
offset	integer		Row to start at; follow nextOffset

Output

structuredContent.laws[] with resource, shortTitle, title, alongside total (matches before paging), returned, offset, limit, truncated, nextOffset and a German note.

The text mirror carries the same rows as structuredContent.laws, never more and never fewer: the page is bounded upstream of both channels rather than one of them being trimmed. When truncated is true the response says so in both, and names resolve_law as the targeted alternative.

{"name":"list_laws","arguments":{"jurisdiction":"AT","q":"Angestellten"}}

→ 7 Gesetze in AT mit "Angestellten" im Kurz- oder Volltitel; diese Antwort enthält alle.
  at-br-10008069 — AngG (Angestelltengesetz)
  at-br-10008073 — GAngG (Gutsangestelltengesetz)
  …

get_provision

Fetch the full text of a statute provision as in force on any date. Set lawAsOf for the historical version, omit it for current text. This point-in-time access is the server's non-substitutable edge: it is authoritative exactly where model memory is not.

Parameter	Type		Notes
resource	string	required	Lowercase statute id from resolve_law, e.g. brao
num	string	required	Provision key. A bare 43a always works and resolves § first, Artikel second. art/ is the namespace of acts whose source publishes a structural type per provision (Austrian RIS). GII and EUR-Lex publish none, so the GG, AEUV, EUV and DSGVO hold their Artikel in sec/ and read “Art.” from the act label; an art/<n> address on such an act resolves onto sec/<n> and the answer says which id it read. Recitals and annexes must be named explicitly, rct/173 and anx/1 or anx/I, because a bare number always means the article and a recital is not operative law. An annex keeps the source's own numbering — Arabic is about three times as common as Roman — and roughly 3 in 5 EU acts hold no separately addressable annex at all.
jurisdiction	DE｜EU｜AT	required
lawAsOf	string YYYY-MM-DD	optional	Version in force on this date. What the answer can prove depends on the source: where a per-provision Inkrafttretensdatum is published (Austrian RIS) the version in force is served, or the call is refused when none is held. Where only an act-level consolidation Stand exists (gesetze-im-internet, EUR-Lex) the consolidation we hold is served with certifiedForRequestedDate: false and a leading warnings line.

Output

The provision object (provisionLabel, num, heading, paragraphs[], uri), plus url, certifiedForRequestedDate, the version and a timeline summary. Read version.basis before quoting a date. in_force means the source published this provision's own Inkrafttretensdatum and inForceFrom is a legal in-force date. consolidation_stand means the source publishes no per-provision date at all, so consolidationStand is the act-level Stand stamped on every provision alike — it moves whenever any provision of the act is amended and is not evidence that this provision changed then. For the full timeline and diffs use get_provision_history.

                  "consolidationsHeld": 1, "note": "This source publishes NO per-provision in-force date. …" }
  }
}

get_provision_history

How a provision changed over time. basis leads and decides what the rest means (see Output). Pass diff to get a text diff between two held texts instead. Statutes only, never judgments, which are immutable point events and carry no valid-time.

Parameter	Type		Notes
resource	string	required
num	string	required
jurisdiction	DE｜EU｜AT	required
diff	{ from?, to? }	optional	Both YYYY-MM-DD. If set, returns a diff instead of the history

Output

Without diff: the timeline envelope — basis (in_force｜consolidation_stand｜mixed), trackedVersions, consolidationsHeld, a note and versions[]. Read basis first: it decides what the dates mean. Where the source publishes a per-provision Inkrafttretensdatum (Austrian RIS), each entry carries inForceFrom / inForceUntil and trackedVersions is a real legal timeline. Where it publishes only an act-level consolidation Stand (gesetze-im-internet, EUR-Lex), each entry carries consolidationStand / supersededByStand, trackedVersions is 0, and the date is the Stand of the WHOLE act — it moves whenever any provision of the act is amended and is not evidence that this provision changed. With diff: the diff object, including a changed boolean and the two endpoints, each stamped with its own basis.

{"name":"get_provision_history",
 "arguments":{"resource":"stgb","num":"243","jurisdiction":"DE",
              "diff":{"from":"2017-01-01","to":"2024-01-01"}}}

→ "stgb/243: zwischen der Konsolidierung vom 2017-07-22 und der Konsolidierung vom 2021-10-01 geändert"

get_decision

One court decision by ECLI or corpus uri, with inline citations. The structured result holds the full section text; the text mirror excerpts each section. Find decisions via search_corpus with tiers: ["case_law"] or browse_documents first.

Parameter	Type		Notes
id	string	required	ECLI or decision uri
jurisdiction	DE｜EU｜AT	required

Output

title, court, fileNumber (the Geschäftszahl), ecli, uri, url and sections[] each with its full text. Missing id returns isError: true.

{"name":"get_decision",
 "arguments":{"id":"ECLI:AT:OGH0002:1972:0030OB00044.72.0420.000","jurisdiction":"AT"}}

get_rechtssatz

Fetch one Rechtssatz in full by its uri, with inline citations. This tool reads only Rechtssätze: a uri of another tier is refused with a pointer to the right read tool rather than silently returning a foreign document.

Parameter	Type		Notes
uri	string	required	e.g. at-rs/RS0000001
jurisdiction	DE｜EU｜AT	required

Output

title, uri, docType: "rechtssatz", url, segments[].

{"name":"get_rechtssatz","arguments":{"uri":"at-rs/RS0000001","jurisdiction":"AT"}}

// wrong tier:
→ isError: "at-rs/… ist ein Dokument vom Typ case_law, kein Rechtssatz — stattdessen
   get_decision (case_law) oder browse_documents (readUri) verwenden."

browse_documents

Two modes in one tool. Without readUri it lists documents as summary plus uri, optionally filtered by type and title. With readUri the structured result holds the full document text. For statutes, fetch full text via get_provision instead, since segments come back empty.

Every uri the listing returns is readable: with type=statute it lists exactly the statutes list_laws lists, so a get_provision on one of them can fail on the provision number but never on the statute id. Listing is a RANKING, not a resolution — to turn a Kurztitel into an id, use resolve_law, which refuses a collision instead of guessing.

Parameter	Type		Notes
jurisdiction	DE｜EU｜AT	required	Scopes both the listing and a readUri fetch; a bare id is never read cross-jurisdiction
type	statute｜case_law｜literature｜admin_publication	optional
q	string	optional	Title filter, listing mode only
limit	integer 1–500	optional
readUri	string	optional	Switches to read mode

Output

Listing: structuredContent.documents[] with uri, title, docType, url. Read: the document with segments[].

{"name":"browse_documents",
 "arguments":{"jurisdiction":"DE","type":"admin_publication","q":"Drucksache","limit":10}}

citation_neighbors

Which provisions a given provision cites (outgoing) and which cite it (incoming): the local citation graph, for spotting related provisions. This layer is derived from free text. Where the source itself publishes the link, prefer document_relations, which is higher-confidence.

Parameter	Type
resource	string	required
num	string	required
jurisdiction	DE｜EU｜AT	required

Output

outgoing[] and incoming[], each edge carrying a uri.

{"name":"citation_neighbors",
 "arguments":{"resource":"brao","num":"43a","jurisdiction":"DE"}}

→ Cites: brao/sec/59m, brao/sec/43e
  Cited by: brao/sec/113, brao/sec/43

document_relations

Source-published relations around a decision, Rechtssatz or provision uri, in both directions. This is a higher-confidence layer than citation_neighbors because the source itself asserts the link. Outgoing gives what the document asserts: a Rechtssatz points to its decision chain via abstracted_from, carrying the Beisatz annotation and the asserted court, date and Geschäftszahl. Incoming gives what points at it. Unresolved rows keep the verbatim evidence and never fabricate a target.

Parameter	Type		Notes
uri	string	required	An ECLI, a Rechtssatz uri, or a provision uri like at-stgb/sec/43a
jurisdiction	DE｜EU｜AT	required

Output

outgoing[] / incoming[], each row with relation, evidence (verbatim), a resolved target or null, plus annotation, assertedCourt, assertedDate, assertedFileNumber. The text mirror renders at most 25 rows per direction and states the remainder, so a heavily applied provision never dumps thousands of edges.

sentencing_statistics

Official German sentencing distribution from the Statistisches Bundesamt (Destatis) Strafverfolgungsstatistik: how convictions split across sentence types, prison-length and fine-size buckets, and juvenile sentences, per year. Use this for Strafzumessungspraxis questions rather than search_corpus, which returns statute and case text. Omit offense to list the available offenses first. Like every corpus-touching tool, it requires a jurisdiction — and this data exists for DE only: an AT or EU call returns an explicit German “nothing held” refusal (structured and in the text mirror), never German numbers, because no Austrian or EU sentencing statistic exists in the corpus.

Parameter	Type		Notes
jurisdiction	DE｜EU｜AT	required	Corpora are never mixed. Held for DE only; AT/EU answer with the honest refusal (held: false, heldJurisdiction: "DE", a German note), and a DE answer carries jurisdiction: "DE" structurally beside the Destatis attribution
offense	string	optional	StGB section (242 or stgb/242) or an aggregate key; omit to enumerate
year	integer	optional	Defaults to the latest year held. Destatis publishes per year, so a year we do not hold is the ordinary miss: the refusal then names the YEAR and lists the years that exist, and only a genuinely unknown offense is answered by pointing at the offense list

Output

jurisdiction (always "DE" — the scope, structurally), offenseKey, offenseLabel, provisionUri, year, totalConvicted, source, and measures with four bucket arrays (sentenceType, prisonDuration, fineRate, juvenileDuration), each bucket carrying bucket, count and share. These are aggregate official statistics, not a case-specific prediction and not legal advice.

With offense omitted, the envelope names its scope (jurisdiction: "DE") and each listed offense carries offenseKey, offenseLabel, provisionUri and years — every statistic year held for it, so one discovery call answers both “which offenses” and “which years”.
