get_chemical_fate_details

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

The annotations already establish that this is read-only, idempotent, open-world, and non-destructive. The description adds no behavioral context beyond that, such as scope, output characteristics, or authentication needs.

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?

It is a single, front-loaded sentence with no wasted words. The purpose is stated immediately.

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 a simple retrieval operation with one well-documented parameter, rich annotations, and an output schema, so the description does not need to explain return values. It is mostly sufficient, though it leaves the relationship to the summary sibling slightly implicit.

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, and the schema itself explains it as a DSSTox Substance Identifier. The description adds no further meaning to the parameter beyond saying it is for a chemical.

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?

The description states a specific verb and resource: retrieve detailed environmental fate data for a chemical. It implicitly distinguishes itself from get_chemical_fate_summary through the word 'detailed', though it does not explicitly name the sibling.

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?

It gives no explicit guidance about when to use this tool versus alternatives such as get_chemical_fate_summary. The intended usage is only weakly implied by 'detailed environmental fate data' and there are no exclusions or prerequisites.

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