get_exposure_ccd_functional_use

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, covering the safety/idempotency profile. The description adds nothing beyond that - no scoping constraints, coverage notes, or return behavior - so it contributes no behavioral value over the structured fields.

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 sentence with no wasted words, and the key action is front-loaded. It is efficient, though the terseness borders on under-specification rather than optimal conciseness.

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 has an output schema so return values need no description, and the single param is fully documented. The description nonetheless omits what the agent most needs: the meaning of 'CCD' and how this tool differs from its exposure-functional-use siblings.

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?

There is a single parameter and schema description coverage is 100%, so the schema already fully documents dtxsid as the DSSTox Substance Identifier. The description adds no format or usage detail beyond the schema, so the baseline 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 ('Retrieve') and a resource ('CCD reported functional use data'), so the basic purpose is identifiable. However, it never explains what 'CCD' is or how this differs from the closely related sibling get_exposure_functional_use, leaving the agent to guess at the distinction.

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?

The description offers no when-to-use guidance and names no alternatives or conditions. With a near-identical sibling present (get_exposure_functional_use, batch_get_exposure_functional_use), the absence of any routing information is a real gap.

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