search_licensed_entities

Read-only

Check whether a company appears on official APAC regulator registers (HKMA, Japan FSA, Taiwan FSC) by name, brand or licence/corporate number. Returns status, source URL and as-of date. Not legal advice. Costs $0.01 USDC on Base via x402.

A3.5/5.0

Behavior4/5

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

Annotations already establish read-only and closed-world behavior, while the description adds key context: return fields (status, source URL, as-of date), a legal disclaimer, and a specific payment cost via x402 on Base. It does not cover rate limits or error behavior, but the added context is substantial.

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 compact and front-loaded: purpose first, then return values, disclaimer, and cost. Every sentence adds useful information without repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers purpose, output fields, cost, and disclaimer, which is useful for a tool without an output schema. However, for a four-parameter search tool with 0% schema description coverage, it leaves important calling details and sibling differentiation unaddressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate, but it only partially does so. It explains that q can be a name, brand, or licence/corporate number and names the three regulators, but it does not explain limit, the cryptic register enum values, jurisdiction filtering, or how register and jurisdiction interact.

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 states a specific verb and resource: checking whether a company appears on official APAC regulator registers by name, brand, or licence/corporate number. It is clear what the tool does, but it does not differentiate itself from the sibling get_licensed_entity.

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?

Usage is implied by the phrase “check whether a company appears,” and the relevant identifiers are named. However, there is no explicit guidance on when to use this search tool versus get_licensed_entity, nor any exclusions.

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