Forced Heirship Risk

forced_heirship_risk

Read-only

Forced-heirship / testamentary-freedom position for a jurisdiction: whether forced heirship exists, the reserved shares (e.g. France réserve héréditaire, Germany Pflichtteil, Switzerland reform), the freely-disposable portion, whether a spouse/children can be disinherited, and how trusts/foundations interact with reserved shares. States the default legal rules — NOT how any estate will devolve. Use ISO alpha-2.

A4.2/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true, openWorldHint=false, destructiveHint=false, so safety is covered structurally. The description adds genuine context beyond that: the result is a static statement of default legal rules rather than a case-specific outcome, which is the key behavioral caveat for interpreting the response.

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?

Scope and the crucial default-rules caveat are front-loaded, and the parenthetical jurisdiction examples (France, Germany, Switzerland) are illustrative rather than filler. The single sentence is dense but every clause carries meaning; only the long enumeration risks mild bloat.

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?

The tool takes one parameter and has an output schema, so return-shape explanation is unnecessary. The description fully covers scope, the legal sub-topics returned, and the important limitation that these are default rules — nothing an agent needs to invoke or interpret it is missing.

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?

With a single parameter at 100% schema description coverage, the schema already fully documents 'cc'. The description's 'Use ISO alpha-2' restates the schema's ISO 3166-1 alpha-2 guidance without adding format, normalization, or failure behavior. Baseline 3 is appropriate.

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 resource (forced-heirship / testamentary-freedom position for a jurisdiction) and enumerates the exact sub-facts returned: reserved shares, freely-disposable portion, disinheritance of spouse/children, and trust/foundation interaction. This clearly separates it from adjacent siblings such as succession_conflict_map and matrimonial_regime_screen.

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 bounds the tool's scope: 'States the default legal rules — NOT how any estate will devolve,' which tells the agent when this is and isn't the right call. It does not, however, name an alternative tool for the excluded case (e.g. a fact-specific succession analysis), so routing is only half-complete.

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