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, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds the ranking basis (recent versus prior growth) and the optional chapter scoping, but leaves 'recent' and 'prior' undefined — no window length, no sort direction, no note on how declining markets surface. Useful context, but the operative behavior is still underspecified.

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

Conciseness4/5

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

Two sentences, zero filler, with the core ranking behavior front-loaded before the use case. The only reservation is that the brevity comes at the cost of the time-window detail an agent needs, so the compactness is efficient but slightly under-informative.

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

Completeness3/5

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

With an output schema present, return values need no explanation, and the annotations cover the safety profile, so the remaining burden is small. Still, for a ranking tool the definition never defines the comparison period or the ordering, which are the two things an agent must understand to interpret results correctly. Adequate but with a clear 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%, so every parameter is already documented in the schema; the baseline is 3. The description only adds that hs2 acts as a narrowing filter and that destinationCountry is the ranking subject, which is marginal value beyond the schema text. It says nothing about the semantics of source or how limit interacts with ranking truncation.

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 — 'Ranks a destination's HS6 markets by recent-versus-prior growth' — plus the optional HS2 narrowing scope. An agent can tell this is a growth-ranking tool rather than a lookup, though it never distinguishes itself by name from close siblings like exim__market__growth, exim__market__trend, or exim__market__entrants.

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

Usage Guidelines3/5

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

The second sentence gives a genuine use case ('find emerging or declining product markets'), which is more than implied usage. However, there is no when-not guidance and no reference to the several sibling market tools that presumably answer overlapping questions, so an agent must guess whether this or market__growth is the right call.

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