List Available Laws

legal_list_laws

Read-onlyIdempotent

List available laws, regulations, and court decisions in the database. Returns abbreviation, title, source type, jurisdiction, document kind, and version date for each entry.

Unfiltered listings can contain thousands of entries; pass a search term or source_type to keep responses focused. Useful for discovering valid law abbreviations to use as filters in legal_search; legal_get_toc shows a listed law's structure.

Not an existence check for a specific law: EUR-Lex entries store the official long title, so a short name or number can miss a law that is in the corpus. legal_lookup with a citation or legal_search with a topic provides alternative retrieval paths; a missing match does not prove absence from the corpus.

Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	Max results per page (default 50).
`offset`	No	Start position for pagination.
`search`	No	Case-insensitive search on abbreviation, title and official short designation ('Elektronischer-Rechtsverkehr-Verordnung'), e.g. 'bgb', 'datenschutz'. Also accepts a CELEX number ('32022L2555') or an EU instrument reference ('2022/2555', 'Richtlinie (EU) 2022/2555') and resolves it to the stored law.
`language`	No	Document language: 'de' (default, German-language documents from German and EU sources) or 'en' (currently EDPB/EDSA data-protection guidance only). DE and EN are separate corpora — a document published in both languages has one entry per language under the same abbreviation. 'en' selects the English corpus regardless of the answer language; 'edsa' is published mostly in English.
`source_type`	No	Filter: 'gii', 'eurlex', 'eurlex_caselaw', 'rechtsprechung', 'bverfge', 'bverwg', 'sachsen_rechtsprechung', 'nrw_rechtsprechung', 'bayern_gesetze', 'nrw_gesetze', 'verwaltungsvorschriften', 'edsa', 'dsk' or 'gesetzesmaterialien'. Note: 'edsa' is published mostly in English: language='en' covers the full set, the DE default only the translated documents.
`jurisdiction`	No	Filter by jurisdiction: 'de' (all German law — matches federal AND state law; federal only is source_type='gii'), 'eu', 'de_by' (Bavaria only), 'de_nw' (North Rhine-Westphalia only), 'de_sn' (Saxony only). Empty = no jurisdiction filter.
`document_kind`	No	Filter by document class: the norm subtypes 'statute', 'regulation' and 'directive' form ONE class (any of them lists all three); 'decision' (court case-law), 'guidance' (supervisory-authority soft law, EDSA/DSK) and 'explanatory_memorandum' (legislative materials) are separate classes.

TDQS

A3.9/5.0

Behavior1/5

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

The description adds useful behavioral context (scale, long-title mismatch, missing matches do not prove absence), but it directly contradicts the openWorldHint:false annotation, which implies a closed world where absence means non-existence. This contradiction mandates a score of 1 and flags an annotation contradiction.

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?

Three paragraphs, each earning its place: purpose, usage guidance, and caveat with alternatives. No filler, and the core purpose is front-loaded in the first sentence.

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?

Given the rich schema (100% coverage) and output schema, the description covers all essential usage context: what it returns, when to use it, what it is not for, and how to manage large listings. The openWorldHint contradiction is a behavioral transparency issue, not a completeness gap.

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 description coverage is 100%, so the schema fully documents all seven parameters. The description adds only a general note to pass search or source_type to focus results, which is practical but not additional parameter-level semantics. Baseline 3 applies.

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 and resource: lists laws, regulations, and court decisions in the database, and enumerates returned fields. Explicitly distinguishes itself from siblings by positioning itself as the way to discover law abbreviations for legal_search, while legal_get_toc shows structure, and clarifies it is not an existence check.

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

Usage Guidelines5/5

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

Provides explicit when-to-use guidance: discovering valid law abbreviations for legal_search. Names alternatives (legal_lookup, legal_search) and states when not to use it (existence check), plus a practical tip to filter for focused responses. This leaves little to inference.

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