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

No annotations exist, so the description carries the full transparency burden, yet it says nothing about whether this is a read-only lookup (implied but unstated), whether it requires authentication, or how the four states are represented. Listing the field names is a small hint at the payload but not a behavioral disclosure.

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?

It is a single short fragment with no filler, but it is under-specified rather than concise — a verb and a return-format note would cost half a sentence and greatly improve it.

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 is the only source of information about what the call yields, and it gives bare field names without meaning, format, or failure behavior. For a zero-parameter status endpoint this leaves the agent guessing about the response.

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 zero parameters, so there is no parameter semantics to explain and the baseline of 4 applies. The description correctly doesn't waste words on non-existent inputs.

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 enumerates the domain fields it concerns (bond, trader status, lane, trial state) but uses no verb at all, so the agent must infer that this is a read that reports current customs standing. It is distinguishable from customs_cross/file/verify_receipt only loosely, via the 'status' framing rather than explicit contrast.

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 guidance, no mention of prerequisites, and no reference to the sibling tools (customs_cross, customs_file, customs_verify_receipt) that an agent would need to choose between. The agent is left to infer usage from the noun phrase alone.

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