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

With no annotations, the description carries the full burden. 'Resolves' implies a read/determination operation, but the description never states it is read-only, whether it requires authorization, or that results are gated (the api_key param hints at a free/paid excerpt split, but that context lives only in the schema). No output shape or rate-limit information is disclosed.

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 dense sentence with no filler, front-loaded on the verb and the scope of regimes. It is jargon-heavy but every clause maps to a real capability, so nothing is wasted.

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?

No annotations and no output schema, so the description is the only place behavioral detail could live, and it omits how results are returned, whether the tool only flags requirements or also validates them, and how the api_key affects output completeness. For a compliance-determination tool this leaves meaningful gaps.

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 schema already documents hs_code, product_category, and api_key, including examples and the enum-like category list. The description adds regulatory framing but no parameter-level syntax or format detail, so the baseline 3 is appropriate.

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 ('Resolves') and a precisely enumerated resource set (CCC certifications, NMPA cosmetic/pharma filings, GACC Decree 248/249 CIFER registration), so an agent knows this determines applicable Chinese import compliance regimes. It doesn't explicitly distinguish itself from siblings like calculate_china_import_taxes or sino_data_transfer_compliance, but the domain is clearly non-overlapping.

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?

There is no when-to-use, when-not-to-use, or alternative-tool guidance. The description only names the regimes it resolves; nothing tells the agent when to reach for this versus the tax calculator or the data-transfer compliance sibling.

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