swagger-petstore---openapi-3.0.updatePetWithForm

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the agent is aware this is a state-changing operation. The description adds only that the input is form data, which is not in annotations. It does not disclose additional behavioral traits like required fields, error behavior, or response details, but given the annotation coverage, the added context is minimal yet non-conflicting.

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?

The description is a concise single sentence that front-loads the action and object. It contains no waste or redundancy, earning a perfect score for 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 description is extremely sparse for a mutation tool. It fails to mention the required pet ID, acceptable form fields, or any constraints. Although an output schema exists, the input side is completely unspecified. The description implies form data but provides no details, leaving the agent uncertain how to construct a valid request.

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 input schema contains zero parameters and schema_description_coverage is 100% vacuously. The description mentions 'form data' but does not enumerate any form fields. Since there are no parameters in the schema, the description adds no parameter semantics, but the baseline for zero parameters is 4, and the mention of form data is a slight bonus.

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 the action ('Updates'), resource ('a pet'), and method ('with form data'), clearly indicating what the tool does. It distinguishes from the sibling updatePet tool by specifying form data as the input format. However, it does not mention the required pet identifier, which is a minor gap.

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?

No usage guidance is provided. The description does not explain when to use this tool over updatePet, deletePet, or other pet operations, nor does it mention any prerequisites or exclusions. The agent receives no context for selecting this tool among alternatives.

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