Instructions

Search document change history (Aenderungshistorie).

Use this tool to track changes to legal documents over time. Shows when documents were created, modified, or deleted.

Available applications (30 total):

Bundesrecht: Bundesnormen, BgblAuth, BgblAlt, BgblPdf, RegV
Landesrecht: Landesnormen, LgblAuth, Lgbl, LgblNO, Vbl, Gemeinderecht, GemeinderechtAuth
Judikatur: Justiz, Vfgh, Vwgh, Bvwg, Lvwg, Dsk, Gbk, Pvak, AsylGH
Sonstige: Bvb, Mrp, Erlaesse, PruefGewO, Avsv, Spg, KmGer, Dok, Normenliste

Example queries:

applikation="Bundesnormen", aenderungen_von="2024-01-01", aenderungen_bis="2024-01-31"
applikation="Justiz", aenderungen_von="2024-06-01"

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)
`applikation`	Yes	Application to search history for - categories: Bundesrecht (Bundesnormen, BgblAuth, BgblAlt, BgblPdf, RegV), Landesrecht (Landesnormen, LgblAuth, Lgbl, LgblNO, Vbl, Gemeinderecht), Judikatur (Justiz, Vfgh, Vwgh, Bvwg, Lvwg, Dsk, Gbk, Pvak, AsylGH), Sonstige (Bvb, Mrp, Erlaesse, PruefGewO, Avsv, Spg, KmGer, Dok, Normenliste)
`aenderungen_bis`	No	Changes to date (YYYY-MM-DD)
`aenderungen_von`	No	Changes from date (YYYY-MM-DD)
`include_deleted`	No	Include deleted documents in results (default: false)
`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

A3.9/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds that results reflect create/modify/delete events and that deleted documents can be excluded, but says nothing about coverage limits of the history, auth, or rate behavior beyond what the limit parameter doc already states.

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?

Front-loaded with a one-line purpose followed by usage context, then a categorized application list and examples. The 30-entry enumeration is bulky but serves as an at-a-glance selector; no sentence is pure filler.

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 an output schema, full parameter descriptions and annotations present, the description carries only the remaining burden of purpose and app selection, which it does. The stale application list ('30 total' vs 36 enum values) is the one gap that could cause an agent to miss valid applications.

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, but the example queries materially add semantics by showing realistic applikation + aenderungen_von/bis combinations, including one with an open-ended range. It does not explain interactions such as include_deleted with paging or the limit override behavior in the description itself.

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

Purpose4/5

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

The definition uses a specific verb+resource ('Search document change history') and explains that it tracks when documents were created, modified, or deleted, which distinguishes it from document-retrieval siblings like ris_dokument. The main flaw is the application inventory: it claims '30 total' and omits several enum values (Verg, Upts, Uvs, Ubas, Umse, Bks), leaving a mild contradiction against the schema.

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 states the purpose context ('use this tool to track changes to legal documents over time') and provides two concrete example invocations showing how to combine applikation with date ranges. It stops short of naming which sibling tool to use instead when the goal is fetching document content rather than history.

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