get_exposure_mmdb_single_sample_by_medium

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds only the medium-filter scoping, with no mention of return shape, pagination, or valid medium values, so it is marginally useful at best.

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?

One front-loaded sentence with no filler or redundancy. It is efficiently sized, though it is terse to the point of omitting useful routing context.

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 an output schema present, return values need no explanation, and the single parameter is fully covered by the schema. However, the definition omits the routing guidance needed to pick this tool over its MMDB siblings and the aggregate variant.

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 100% for the single 'medium' parameter, so the schema already does the documenting. The description confirms that medium acts as a filter but adds no format, naming, or valid-value detail beyond that baseline.

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?

States a specific verb and resource ('Retrieve MMDB single-sample data') and the scope ('filtered by medium'). The 'single-sample' phrasing implicitly distinguishes it from the aggregate MMDB siblings, though it never names them explicitly.

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?

No when-to-use guidance and no alternatives named. An agent cannot tell from the description whether to call this versus get_exposure_mmdb_single_sample_by_dtxsid or get_exposure_mmdb_aggregate_by_medium.

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