Play Style + Toys

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

Annotations include readOnlyHint=true, destructiveHint=false, idempotentHint=true, but the description adds no behavioral context beyond 'Preferred play and toy types.' It does not describe what the output looks like or any side effects, missing an opportunity to add value.

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 very short (one sentence plus group label and example), but it sacrifices clarity for brevity. It earns its place poorly because it does not convey the tool's purpose fully.

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 7 parameters and many sibling tools, the description is incomplete. It does not explain what the tool returns, how to interpret results, or any prerequisites. The lack of output schema worsens 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?

Schema coverage is 100%, so baseline is 3. The description includes an example request body, but this duplicates schema information. No additional meaning is added beyond what the schema already provides.

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 is a noun phrase 'Preferred play and toy types.' It lacks a verb and does not explicitly state what the tool does, e.g., 'Calculate' or 'Provide.' It is vague and does not distinguish from sibling tools like pet_personality or pet_temperament.

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 on when to use this tool versus alternatives such as pet_personality or pet_training_style. There are many pet-related tools, but the description offers no context for selection.

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