get_pet_details

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

No annotations are provided, so the description carries the full behavioral burden. It implies a read ('Get') and hints at unprocessed output ('raw'), but says nothing about permissions, whether it returns a single pet or a collection, rate limits, or the shape of the response.

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, front-loaded sentence with no filler. It is appropriately sized, though the brevity comes at the cost of the missing context noted elsewhere.

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?

No annotations and no output schema, so the description must explain both behavior and return value on its own. It does not say which pet is fetched (there is no input parameter at all), what 'raw' data contains, or what the response looks like — a significant gap for a tool whose entire contract rests on the description.

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?

The tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. If anything, the absence of any identifier parameter raises a question the description does not answer, but that is not a parameter-semantics failure.

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 ('Get') and a resource ('pet data') with a scope qualifier ('raw ... including microchip tag information'). However, 'raw pet data' is vague about what is actually returned, and the description never distinguishes this from the sibling get_pet_report or explains why an agent would pick one over the other.

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 any alternative. With siblings like get_pet_report and list_pets present, an agent has no basis for routing beyond the surface verb difference.

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