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.

TDQS

A4/5.0
Behavior4/5

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

Annotations already supply readOnlyHint=true and destructiveHint=false, so the description's burden is lighter. It adds value by disclosing that the output states default legal rules rather than predicting actual estate devolution, and by listing the specific questions the tool addresses. This is honest, useful behavioral context beyond the structured 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?

The description is a single dense, front-loaded passage with no filler; the jurisdiction-level concept comes first, followed by concrete legal aspects and a crucial caveat. The illustrative country examples earn their place, though the long list makes it slightly harder to parse at a glance.

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?

For a one-parameter tool with an output schema and read-only annotations, the description covers purpose, scope, key legal dimensions, and a critical exclusion. Nothing an agent needs to select and invoke the tool correctly appears to be 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?

Schema description coverage is 100%, so baseline 3 applies. The description only reiterates 'Use ISO alpha-2', which the schema already states with examples and uppercase guidance. It adds no new meaning beyond the parameter 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 specifies a jurisdiction-level forced-heirship and testamentary-freedom position and enumerates the exact legal aspects covered: reserved shares, freely-disposable portion, disinheritance, and trust/foundation interaction. It also scope-limits itself to default legal rules, which distinguishes it from estate-devolution and conflict-of-laws siblings.

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

Usage Guidelines3/5

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

The 'for a jurisdiction' and 'NOT how any estate will devolve' language provides a clear context and one exclusion, but the description never names an alternative sibling or explicit when-not condition. An agent must infer when to choose this over succession_conflict_map or matrimonial_regime_screen from sibling names alone.

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