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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds only the weak qualifier 'reported' and omits behavioral traits such as the current_only=true default (which hides historical observations) and pagination behavior.

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?

A single 10-word sentence with zero filler, and the core purpose ('return reported lane-risk observations') is front-loaded. Every word earns its place.

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?

An output schema exists, so return values need no explanation, and there are no required parameters. But with 11 parameters and no explanation of core domain concepts — what 'lane risk' means, how attention_level and risk_driver operate, what current_only defaults to — the description is too thin for an agent to invoke this tool with confidence.

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?

Schema description coverage is only 36%, so the description must compensate for the 11 parameters. It groups filters into 'country and product' (exporter/importer_iso3, hs_code/hs_chapter) but never mentions risk_driver, attention_level, current_only, min_trade_usd, or q — several of which are central to a risk tool.

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 states a specific verb ('Return') and resource ('reported lane-risk observations'), clearly marking this as the risk-data tool. The 'country and product filters' scope distinguishes it from sibling tools that return trade flows or pages, so an agent can tell it apart from get_corridor_trade and get_lane_page without opening schemas.

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 explicit when-to-use or when-not-to-use guidance, and no alternatives are named. The phrase 'for country and product filters' implies a usage context, but the agent is left to infer when this tool is preferred over siblings like get_lane_page or get_global_trade.

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