Read-only

Search the Austrian Federal Law Gazette (Bundesgesetzblatt) to retrieve official publications of laws, ordinances, and treaties using filters such as year, part, number, or full-text search.

Instructions

Search Austrian Federal Law Gazettes (Bundesgesetzblatt).

Use this tool for historical research and tracking when laws were enacted. Contains official publications of federal laws, ordinances, and treaties.

Example queries:

bgblnummer="120", jahrgang="2023", teil="1" -> Find specific gazette
suchworte="Klimaschutz" -> Full-text search in gazettes

Input Schema

TableJSON Schema

Name	Required	Description	Default
`teil`	No	Part - "1" (I=Laws), "2" (II=Ordinances), "3" (III=Treaties)
`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 gazette titles
`jahrgang`	No	Year (e.g., "2023")
`suchworte`	No	Full-text search terms
`bgblnummer`	No	Gazette number (e.g., "120")
`applikation`	No	"BgblAuth" (authentic 2004+, default), "BgblPdf" (PDF), "BgblAlt" (1945-2003)	BgblAuth
`response_format`	No	"markdown" (default) or "json"	markdown

Output Schema

TableJSON 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

A3.9/5.0

Behavior3/5

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

Annotations (readOnlyHint=true, openWorldHint=true, destructiveHint=false) already carry the safety profile, and the description's search framing is consistent with them. The description adds content-coverage context (laws, ordinances, treaties), but the most valuable behavioral detail — payload cost and auto-shrinking page behavior — lives in the schema's limit parameter, not in the description itself.

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

Conciseness4/5

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

Purpose, use case, content scope, and examples are packed into a compact structure with the purpose front-loaded. The example queries earn their place by showing realistic parameter combinations, though the example block could be marginally tighter without losing value.

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?

With 9 fully-documented parameters, an output schema, and complete annotations, the description covers purpose, use case, and content scope adequately. The only gap is explicit sibling routing (e.g., pointing to ris_bundesrecht for current consolidated law), which is a minor omission given how rich the schema and output schema already are.

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

Parameters3/5

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

All 9 parameters are documented at 100% schema coverage, with the limit parameter's description being especially rich (payload budget and page-size fallback). The description's two example queries add light combinatorial guidance (which parameters work together), but this is marginal value layered on top of a fully self-documenting schema.

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?

Names a specific verb (Search) and resource (Austrian Federal Law Gazettes), and the 'Federal' qualifier distinguishes it from sibling ris_landesgesetzblatt (state gazette). The content note ('official publications of federal laws, ordinances, and treaties') and the two example queries pin down the exact scope, so an agent can tell it apart from the consolidated-law and judicature siblings without opening schemas.

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?

States a clear use case — 'historical research and tracking when laws were enacted' — which implicitly separates it from siblings like ris_bundesrecht (current consolidated law) and ris_judikatur (court decisions). However, it never names these alternatives or states when NOT to use this tool, leaving part of the disambiguation to the agent.

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