Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	Max entries per page (default 100).
`offset`	No	Start position for pagination.
`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	'gii', 'eurlex', 'eurlex_caselaw', 'rechtsprechung', 'bverfge', 'bverwg', 'sachsen_rechtsprechung', 'nrw_rechtsprechung', 'bayern_gesetze', 'nrw_gesetze', 'verwaltungsvorschriften', 'edsa', 'dsk' or 'gesetzesmaterialien'. Empty = auto-detect; where an abbreviation names a law in two sources, the answer lists both. Note: 'edsa' is published mostly in English: language='en' covers the full set, the DE default only the translated documents.
`law_abbreviation`	Yes	Law abbreviation, e.g. 'bgb', 'dsgvo', 'stgb'.

A4.3/5.0

Behavior4/5

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

Annotations already mark the tool as read-only, idempotent, and non-destructive, so the description does not need to repeat that. It adds useful behavioral context beyond annotations: results are in document order, pagination exists for large laws, and the output feeds a downstream tool.

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 appropriately sized: one front-loaded sentence states the core action and return values, and a second compact sentence provides the key workflow hint and pagination note. No wasted words.

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 output schema, rich parameter schemas, and annotations, the description covers what an agent needs to select and invoke the tool correctly. It explains the tool's role in the larger workflow (navigate TOC → get_context) and notes the pagination behavior.

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?

Parameter coverage in the schema is 100%, so the schema already documents each parameter, including defaults, ranges, and enum semantics. The description adds no new parameter-level detail; the mention of pagination aligns with limit/offset but does not go beyond the 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?

The description clearly states the tool fetches the table of contents for a specific law or court decision and enumerates the returned items (norm keys, titles, chapter headings). It uses a specific verb plus resource and distinguishes itself from legal_get_context by framing this as the structural overview.

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?

The description explains when to use it—when an overview of a law's structure is needed—and explicitly connects the returned norm_id to legal_get_context for full text. It does not name alternatives or exclusions, but the intended usage path is clear enough to guide an agent.

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