petstore-api.updatePetWithForm

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

Annotations already indicate readOnlyHint: false and destructiveHint: true. The description only adds 'form data' as a minor behavioral detail but does not explain what gets changed, whether existing data is replaced, or what other effects occur.

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 single concise, front-loaded sentence with no redundant filler. It is not overly verbose, though it omits useful operational details.

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 incomplete for executing this operation: it does not say how to identify the pet, which form fields exist, or what will happen to the pet. The empty input schema makes this ambiguity worse, and the description does not fill the gap.

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 has zero parameters with 100% empty coverage, so the baseline is high. 'Form data' implies hidden fields, but with no formal parameters, the description does not need to compensate for a parameter list.

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?

Description uses a specific verb 'Updates' and states a clear resource ('a pet in the store') plus a specific method ('with form data'). It distinguishes this tool from updatePet by emphasizing form-data submission.

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 single sentence provides no guidance about when to choose this tool versus updatePet, addPet, or deletePet. It names the action but gives no context, prerequisites, or exclusions.

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