get_exposure_product_data

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 fully covered structurally. The description adds no behavioral context beyond that – no input expectations, no note that it queries an external/open-world database, no scope limits.

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?

At four words it is certainly compact and front-loaded, but the brevity crosses into under-specification rather than economy – nothing earns its place because very little is said.

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 not be spelled out, but for a tool sitting among many similarly named exposure/CPDat siblings the description is too thin: it never clarifies scope, relationship to batch variants, or what distinguishes CPDat product data from other exposure endpoints.

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%: the sole dtxsid parameter is documented as DSSTox Substance Identifier. The description adds nothing about the identifier format or where to obtain it, so the baseline 3 is appropriate.

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 (Retrieve) and resource (CPDat product data), which is more than a tautology. However, it does not explain what CPDat product data is or how this differs from the close sibling batch_get_exposure_product_data or from search_cpdat, leaving the agent to infer 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?

There is no when-to-use guidance, no prerequisites, and no mention of the single-record-vs-batch alternative (batch_get_exposure_product_data) despite that sibling existing in the toolset. The agent gets no routing signal beyond the name.

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