The philanthropy/legacy complement to the residence/citizenship + tax + trust layers.

TDQS

A3.7/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds the characteristics the search surfaces (donor tax relief, entity tax status, cross-border granting, standout vehicle), which is useful, but discloses no pagination, ranking, or result-shaping behavior beyond that.

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?

Purpose is front-loaded in the first clause, with the vehicle enumeration and positioning following. It is a single dense sentence plus a positioning clause, slightly burdened by the long example list but with no genuinely wasted sentences.

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?

With an output schema present, the description need not explain return values, and it correctly focuses on scope, vehicle coverage, and domain positioning. For a low-complexity read-only tool with two optional parameters, this is nearly complete; only explicit sibling routing 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?

Schema description coverage is 100%, so both parameters are already documented (including the 'vehicle' examples and the donor_relief filter meaning) in the schema. The description echoes the same vehicle examples without adding format or semantics beyond what the schema provides, making the 3 baseline 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?

The description pairs a specific verb ('Find') with a tightly scoped resource ('jurisdictions for setting up a CHARITABLE/PHILANTHROPIC structure') and enumerates the vehicle types it searches over. By framing itself as 'the philanthropy/legacy complement to the residence/citizenship + tax + trust layers,' it distinguishes itself from siblings like find_trust_jurisdictions and find_formation_jurisdictions without the agent opening a schema.

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 positioning sentence ('complement to the residence/citizenship + tax + trust layers') implies the domain in which this tool is relevant, but there is no explicit when-to-use/when-not guidance or named alternative to route to. Usage is inferable rather than stated.

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