Read-only

Search Austrian court decisions (Judikatur) by keyword, jurisdiction, court, and date. Filter results by document type to retrieve full texts or headnotes.

Instructions

Search Austrian court decisions (Judikatur).

Use this tool to find court decisions from Austrian courts. Choose the jurisdiction via "gerichtsbarkeit" (which court system to search).

RIS distinguishes two document kinds, controlled by "dokumenttyp":

Rechtssatz: abstract legal principle / headnote (Leitsatz) distilled from a decision
Entscheidungstext: the full decision text including reasoning (Begruendung) The default "beide" searches both for the most complete results.

Example queries:

gerichtsbarkeit="Vfgh", suchworte="Grundrecht" -> Constitutional Court decisions
suchworte="Schadenersatz", gericht="OGH" -> Only Supreme Court (OGH) decisions
norm="1295 ABGB" -> Which decisions cite §1295 ABGB?
gerichtsbarkeit="Justiz", fachgebiet="Arbeitsrecht", sortierung="datum_ab" -> Newest labor-law decisions

`seite`	No	Page number
`gericht`	No	Filter by the actual court within the jurisdiction (e.g., "OGH", "OLG Wien"). Applies to gerichtsbarkeit="Justiz".

`sammlungsnummer`	No	Collection number: VfSlg (gerichtsbarkeit="Vfgh") or VwSlg (gerichtsbarkeit="Vwgh").

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the description correctly doesn't restate those. It adds meaningful behavioral context beyond annotations: the limit parameter's payload cost and automatic page-size fallback, and the constraint that fachgebiet only matches full decision texts (requiring dokumenttyp 'entscheidungstext' or 'beide'). This is valuable transparency for a search tool with pagination and filtering quirks.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured and front-loaded: a one-sentence summary leads, followed by a concise explanation of the two document kinds and then practical examples. Every sentence serves a purpose—either explaining semantics, constraints, or usage—without redundancy. The length is justified by the tool's complexity, and the organization aids readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 16 optional parameters, full schema coverage, an output schema, and the annotations, the description covers the essential decision points: what to search, how to filter, and key caveats. It doesn't explicitly walk through every parameter, but the schema already does that. The description's focus on the most impactful parameters and their interactions is sufficient for an agent to use the tool effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds significant value by clarifying parameter interactions (e.g., gericht applies only to 'Justiz', fachgebiet requires specific document types, and limit's payload implications). It also gives example queries that map parameter combinations to real use cases, which goes beyond the schema's individual field descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Search') and resource ('Austrian court decisions (Judikatur)'), and clearly differentiates from sibling RIS tools by focusing on case law. The description goes further to distinguish the two document kinds (Rechtssatz vs. Entscheidungstext) and provides concrete examples, leaving no ambiguity about what the tool does.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit guidance on choosing jurisdiction ('gerichtsbarkeit'), document type ('dokumenttyp'), and gives multiple example queries illustrating different use cases (e.g., filtering by court, norm, subject area). While it doesn't explicitly state when NOT to use this tool versus siblings like ris_bundesrecht, the domain focus is clear enough for an agent to select it appropriately. The lack of explicit exclusion of alternatives is the only gap.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
