swagger-petstore---openapi-3.0.placeOrder

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

The description adds no behavioral context beyond what the annotations already provide. Annotations indicate destructiveHint=true and readOnlyHint=false, but the description doesn't explain side effects such as order creation, inventory impact, or any required permissions.

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, clear, front-loaded sentence with no filler or wasted words. It conveys the essential purpose efficiently.

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?

Given the zero-parameter schema and presence of an output schema, this is minimally adequate for understanding the tool's purpose. However, it lacks practical invocation context and side-effect details, making it only barely complete for an action that places an order.

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?

There are zero parameters and the schema is empty, so parameter semantics are not a concern. The no-parameter baseline is 4, and the description does not need to add parameter-level meaning.

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 uses a specific verb and resource ('Place an order for a pet'), making the core action clear. However, it doesn't distinguish this tool from the sibling 'petstore-api.placeOrder' or other order-related operations, so it falls short of a 5.

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 guidance is given about when to use this tool versus alternatives, what prerequisites exist, or what excludes its use. With multiple pet-store tools and a duplicate sibling placeOrder, the agent has no basis for selecting this specific tool.

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