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

No annotations are provided, so the description carries the full behavioral burden. 'Checks' reasonably conveys a read-only, non-mutating lookup and it enumerates the regimes covered, but it says nothing about result freshness, whether suspensions are time-sensitive, permissions, or rate limits that a compliance tool would reasonably need to disclose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single tightly packed sentence with no filler, and the core purpose is front-loaded before the qualifying details. It is dense but every clause carries scope information, so nothing reads as padding.

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

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

With no annotations and no output schema, the description must stand alone, and it adequately covers scope and subject matter. It still omits what a check returns (findings, status, license requirements) and any temporal caveat, which matters for a regulatory-lookup tool with three optional inputs.

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

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

Schema description coverage is 100%, so the three parameters are already fully documented with examples and an enum for destination_market. The description adds only loose alignment between the categories it names (minerals, batteries, tech) and the material_keyword/hs_code inputs; it adds no format or syntax detail beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Checks') and a well-defined resource (MOFCOM export control regimes, dual-use licensing, truce suspensions) with explicit subject-matter scope (minerals, batteries, tech). It implicitly distinguishes itself from 'assess_importability' (import side) and 'resolve_gb_standards' (standards lookup), though it never names those siblings to draw the boundary explicitly.

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

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

The description implies when the tool applies by scoping it to minerals, batteries, tech and US/EU/global markets, which guides an agent toward relevant queries. However, it gives no explicit when-to-use/when-not statements and never points to an alternative tool for adjacent questions like importability or standards.

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