Rechtswert mit Quelle

rechtswert

Read-onlyIdempotent

Germany only. Look up one German employment law value (Rechtswert) by its key, e.g. mindestlohn (minimum wage), minijobGrenze, bbgRv, urlaubMindest. Returns the value valid on the given date, all dated values, the legal norm, the official source link, the date it was last checked and its status.

Input Schema

Name	Required	Description	Default
`kennung`	Yes	Key of the value, e.g. mindestlohn

Output Schema

Name	Required	Description
`stand`	Yes
`fallen`	No
`hinweis`	Yes
`quellen`	Yes
`ergebnis`	Yes	Result of the tool; its fields differ per tool

TDQS

A4/5.0

Behavior4/5

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

The annotations already establish that this is read-only, idempotent, non-destructive, and non-open-world. The description adds useful behavioral context beyond them: it returns the value valid on a given date, all dated values, the legal norm, the official source link, the last-checked date, and status. It does not contradict any annotation.

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 two efficient sentences with the Germany-only constraint front-loaded and the lookup action stated immediately. Every clause contributes either scope, usage context, or return-value information.

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 the low-complexity lookup, two documented parameters, rich annotations, and an output schema, the description is nearly complete. The only minor gap is that it does not explicitly tell the agent where to go if the key is unknown, such as rechtswerte_suchen.

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 already documents both kennung and stichtag, including the key example and date semantics. The description repeats the key example and date-validity notion but adds no significant parameter detail beyond the schema.

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 description uses a specific verb and resource: "Look up one German employment law value (Rechtswert) by its key," with concrete key examples such as mindestlohn and minijobGrenze. It implies a single-key lookup rather than a search, though it does not explicitly name the sibling search tool rechtswerte_suchen as the alternative.

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 gives a clear use context: use it to retrieve one value when the key is known, and it scopes the tool to Germany. It does not explicitly state when to use rechtswerte_suchen or mindestlohn_check instead, so the guidance is clear but not exhaustive.

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