swagger-petstore---openapi-3.0.deletePet

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

The annotations already provide destructiveHint=true, readOnlyHint=false, and idempotentHint=true, and the description aligns with those signals. However, the description adds only 'pet' as the target and does not disclose irreversibility, error behavior, or side effects.

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 one short sentence with no wasted words. It is front-loaded and immediately communicates the action.

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?

With annotations and an output schema present, the description does not need to explain return values. Still, it does not clarify how the tool chooses which pet to delete—especially given the empty input schema—nor what happens after deletion, so it is minimal but not fully complete.

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 properties, so there are no parameter semantics to explain, and a baseline of 4 is appropriate. If the API actually requires a petId, that would be a schema-level omission rather than a description-level one.

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?

'Deletes a pet' clearly identifies the action and resource, and it distinguishes this tool from update/get pet tools and delete order/delete user siblings. However, it is minimal and does not specify how a pet is selected or what scope of deletion is intended.

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 gives no when-to-use vs when-not-to-use guidance, and no alternative sibling tools are mentioned. For a destructive operation, an agent would benefit from explicit guidance like 'verify the pet exists before deleting' or 'use getPetById first.'

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