Retrieve the change history of legal documents in the Austrian RIS database, filtering by application and date range, with optional inclusion of deleted records.

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.

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

TableJSON 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

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

TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, covering the safety profile. The description adds meaningful context beyond annotations by specifying what the tool surfaces (created/modified/deleted events), and the limit parameter description adds rich behavioral detail about payload budgets and automatic page-size downgrades. No contradiction with annotations.

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?

Well-structured: purpose is front-loaded, followed by the application list and examples. The application list is somewhat redundant with the schema's enum descriptions, and the count ('30 total') slightly understates the 36 enum values listed, but the overall layout is clean and scannable.

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 7 parameters, an output schema, and rich annotations, the description covers the key operational aspects: what it tracks, which applications it covers, and how to form queries. Return-value details are covered by the output schema, so that gap is acceptable. The minor undercount of applications is a small incompleteness.

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?

Schema coverage is 100%, so the schema already documents all 7 parameters in detail (including the very thorough limit description). The description's added value is marginal — the application list duplicates the schema's applikation description, and the example queries reinforce usage patterns. This meets the baseline for high schema coverage.

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+resource ('Search document change history') and explains what it does: track creation, modification, and deletion of legal documents over time. This clearly differentiates it from siblings like ris_dokument or ris_bundesrecht, which are document-retrieval tools rather than history-search tools.

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?

Explicitly says 'Use this tool to track changes to legal documents over time', giving clear usage context, and provides concrete example queries with parameter values. It doesn't explicitly name alternatives or state when not to use it, but the purpose is sufficiently distinct from the sibling retrieval tools to route an agent correctly.

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