batch_get_exposure_product_data

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds nothing on top of that: no batch size limits, no partial-failure behavior when some DTXSIDs are invalid, no latency or rate-limit context for a batch call.

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 no filler and the batch scope front-loaded. It is efficiently sized, though its brevity is partly under-specification rather than true density.

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?

The tool is structurally simple (one required array parameter) and an output schema exists, so return values need not be described. Still, the description omits any notion of batch limits or failure handling, which is the main thing an agent needs before issuing a multi-ID call.

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?

Only one parameter, and the schema documents it fully (100% coverage) as a list of DSSTox Substance Identifiers with minItems 1. The description adds no extra meaning about accepted ID formats or how many IDs are practical per call, so the baseline of 3 applies.

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 (fetch), a resource (CPDat product data) and a batch scope, which loosely separates it from the single-item sibling get_exposure_product_data. However, 'CPDat' is unexplained domain jargon and the description gives no sense of what the product data contains, so it is only marginally more informative than the tool name.

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 prerequisite for resolving DTXSIDs first, and no named alternative. The 'batch' prefix weakly implies 'use this for many IDs', but nothing states when to prefer it over get_exposure_product_data or over the other batch_get_exposure_* tools.

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