get_exposure_mmdb_aggregate_by_dtxsid

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, covering the safety profile. The description adds nothing beyond that – no mention of what an "aggregate" contains, aggregation granularity, or any behavioral constraint. It neither contradicts nor enriches the annotations.

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 short phrase with zero filler, so nothing needs trimming. It is front-loaded, though the extreme brevity edges toward under-specification rather than economical clarity.

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 needn't be described, but the description fails to clarify what "MMDB aggregate" means relative to the single-sample and by-medium variants, which is exactly what an agent needs in this dense sibling set. Too thin for the tool's complexity.

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 dtxsid parameter, so the schema carries the burden; baseline 3 applies. The description adds no meaning about how dtxsid is interpreted or what form the aggregate takes.

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 verb ("Retrieve") and a resource ("MMDB aggregate records"), so the basic purpose is identifiable. However, it does not distinguish this tool from close siblings like get_exposure_mmdb_aggregate_by_medium or get_exposure_mmdb_single_sample_by_dtxsid, and "aggregate records" is left undefined. Vague on scope.

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 guidance on when to use this tool versus the numerous sibling MMDB/exposure tools. The name hints at dtxsid-based lookup, but the description itself offers no context, prerequisites, or alternatives.

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