B3.4/5.0

Behavior3/5

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

Annotations already cover the safety profile (readOnly, idempotent, non-destructive, closed-world), so the burden is light. The description adds the signal categories returned, but discloses nothing about limits, auth, or data freshness beyond that.

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 tight sentences with the capability front-loaded and the usage note following. No filler, though the second sentence is slightly vague about what constitutes growing/concentrated.

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?

Output schema exists, so return values need no explanation, and annotations carry the safety profile. However, for a 6-parameter tool the description omits any mention of the date range or origin filters, leaving the agent to discover half the query surface in the schema.

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 the baseline is 3. The phrase "HS code and/or destination" usefully echoes the anyOf at-least-one constraint, but the description ignores the from/to time range and origin country filters entirely.

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 (Returns) and resource (demand, buyer concentration and momentum signals) scoped to an HS code and/or destination. Clear enough to act on, but it does not name or distinguish itself from overlapping siblings like exim__market__momentum, exim__market__growth, or exim__shipments__route-signals.

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?

"Use it for a quick read on whether a market is growing or concentrated" gives an implied use context, but there are no exclusions or named alternatives despite several sibling tools covering similar market-signal territory. The when-to-use is suggested, not explicit.

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