TDQS

B3.4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered. The description adds what the payload contains (effective rate, remedies, protection level), but says nothing about result volume, pagination behavior beyond the limit param, or data-source caveats. Adds some value against an already-strong annotation set.

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?

One sentence, no filler, with the resource named first and the scoping dimensions trailing. Nothing could be trimmed without losing information.

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

Completeness4/5

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

An output schema exists, so return values need not be described, and annotations cover the safety profile. For a 7-parameter, zero-required query tool the description is adequate, but a note on what an empty result means or how defaults resolve would close the remaining gap.

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

Parameters3/5

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

Schema description coverage is 100% and every parameter is documented there, including HS-code padding rules and the origin/destination ISO2 conventions. The description only restates the same dimensions (HS code, origin, destination, date range) without adding format, default or fallback semantics. Baseline 3 applies when the schema carries the load.

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?

States a specific verb and resource: returns effective rate, trade remedies and protection level, scoped by HS code, origin, destination and date range. That is concrete and recognizable. It does not, however, differentiate itself from close siblings such as exim__duty__fta or exim__tariff, leaving the agent to infer the boundary from names alone.

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

Usage Guidelines2/5

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

The description never states when to choose this tool over exim__duty__fta, exim__tariff or exim__trade__lookup, nor any prerequisites. Usage has to be reverse-engineered from the parameter list. No exclusions or alternative routing is offered.

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