Instructions

Search Austrian federal laws (Bundesrecht).

Use this tool to find Austrian federal legislation like ABGB, StGB, UGB, etc.

Search strategy: "titel" and "paragraph" are the precise entry points — prefer them whenever the law or the section is known ("paragraph" is ignored for applikation="Erv", the English translations). "suchworte" runs a broad full-text search and the RIS API returns those hits ordered alphabetically by law title, not by relevance, so a common term buries the relevant law under thousands of results. Austrian law often splits one topic across several statutes, so look for a companion law: warranty, for example, is covered both by the VGG (consumer sales, B2C, in force since 2022) and by §§ 922 ff ABGB (general warranty law, including B2B).

Example queries:

suchworte="Mietrecht" -> Find laws mentioning rent law
titel="ABGB", paragraph="1295" -> Find specific ABGB section
titel="B-VG", paragraph="7", abschnitt_typ="Artikel" -> Article-based laws
titel="ABGB", fassung_vom="2015-01-01" -> Consolidated version as of a date
applikation="Begut" -> Search draft legislation

Input Schema

Name	Required	Description	Default
`limit`	No	Results per page: 10, 20, 50 or 100 (default: 20). Every hit costs about 1k characters of structured payload, so prefer 20 for browsing and 50 for a broad survey; a page that would exceed the payload budget is delivered at the next smaller page size and says so (page_size, query.limit and notice).
`seite`	No	Page number (default: 1)
`titel`	No	Search in law titles (e.g., "ABGB", "Strafgesetzbuch")
`paragraph`	No	Section number to search for (e.g., "1295" for §1295, "7" for Art 7)
`suchworte`	No	Broad full-text search terms (e.g., "Mietrecht", "Schadenersatz"). Hits come back ordered alphabetically by law title, not by relevance — prefer "titel" and/or "paragraph" whenever the law or the section is known.
`applikation`	No	Data source - "BrKons" (consolidated, default), "Begut" (drafts), "BgblAuth" (gazette), "Erv" (English translations)	BrKons
`fassung_vom`	No	Consolidated version as of this date (YYYY-MM-DD) — retrieves the law text as it stood on that day. Not supported for "Erv".
`abschnitt_typ`	No	Type of section that "paragraph" refers to: "Paragraph" (default), "Artikel" (article-based laws like B-VG), or "Anlage" (annex). "Art 7 B-VG" requires "Artikel".	Paragraph
`response_format`	No	"markdown" (default) or "json"	markdown

Output Schema

Name	Required	Description
`page`	Yes	Page number of this result set (1-based)
`query`	No	Echo of the validated search parameters alongside the tool name — re-issue the call with an incremented "seite" for the next page
`notice`	No	Present when the page was delivered at a smaller size than requested to fit the payload budget — page, page_size and query already describe the delivered page; page with query.limit
`has_more`	Yes	Whether further result pages are available
`documents`	Yes	The documents on this page
`page_size`	Yes	Number of documents per page
`total_hits`	Yes	Total number of documents in RIS matching the search

A4.8/5.0

Behavior5/5

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

Beyond the read-only/open-world annotations, it discloses important behavioral traits: suchworte results are ordered alphabetically by law title rather than relevance, paragraph is ignored for Erv English translations, and Austrian law often splits a topic across multiple statutes. These details materially affect how an agent should search and interpret results.

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?

The description is front-loaded with purpose, then strategy, then examples. Each sentence carries practical value: the search-strategy paragraph and examples directly affect query construction rather than restating schema text.

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

Completeness5/5

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

For a 9-parameter, optional-parameter search tool with a rich schema and output schema, the description provides the missing strategic context: when to prefer each search mode, how parameters interact, and representative query patterns. Return-value details are correctly left to the output schema.

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

Parameters5/5

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

Although schema coverage is already 100%, the description adds strategic semantics beyond the field definitions: titel and paragraph are precise entry points, suchworte is broad and non-relevance-ranked, paragraph is ignored for Erv, and abschnitt_typ must be Artikel for article-based laws such as the B-VG. The example queries concretely demonstrate how parameters combine.

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?

The description states a specific verb and resource: search Austrian federal laws (Bundesrecht), with concrete examples such as ABGB, StGB, and UGB. It also distinguishes the federal-law scope from sibling tools like ris_landesrecht and ris_judikatur by naming exactly what body of law it covers.

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?

It gives explicit search guidance: use titel and paragraph as precise entry points, use suchworte only for broad full-text search, and be aware of alphabetical rather than relevance ordering. It does not explicitly compare itself against sibling tools such as ris_landesrecht or ris_judikatur, but the federal-law scope makes the intended use clear.

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