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

The readOnlyHint annotation is consistent with the description. The description adds valuable behavioral context by stating the price (0.050 USDC) and implying a payment requirement, which is not covered by annotations. It does not contradict the annotation.

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?

The description is a single concise sentence with a colon, listing key content and price. It is efficient and front-loaded, though it uses abbreviations (AOC, HE) that could be expanded for clarity.

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?

Given the lack of an output schema and only one optional parameter, the description covers the main content areas and pricing. It does not describe return format, but for a read-only information tool with a simple schema, this is reasonably complete.

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?

The input schema has 100% coverage, describing the payment_tx_hash parameter clearly. The description adds only indirect context (price) but does not elaborate on the parameter beyond what the schema already states, which is acceptable given the baseline of 3 for full schema coverage.

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?

The description clearly identifies the tool's domain (import/export Caribbean customs flows, Dubai opportunities, logistics, certifications) and distinguishes it from siblings by its specific subject area. Though it lacks an explicit verb like 'get', the tool name contains 'get' and the content list makes its purpose evident.

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?

No guidance is provided on when to use this tool versus alternatives. It does not mention any exclusions or alternative tools, leaving the agent to infer usage solely from the domain name.

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