Updates a pet in the store with form data.

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

Beyond the annotation 'openWorldHint: true', the description adds no behavioral details such as whether updates are partial or full, or any side effects. It does not contradict annotations, but it provides minimal additional transparency.

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 sentence that is concise and front-loaded. However, it slightly repeats the title, reducing impact.

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 complexity (sibling tools, no output schema), the description is insufficient. It does not explain return values, error states, or how form data differs from other update methods, leaving the agent with gaps.

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 schema coverage is 100% with each parameter described. The description does not add new semantic meaning beyond what the schema already provides, so a baseline score of 3 is appropriate.

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 clearly states the verb 'updates' and the resource 'pet', using 'form data' to hint at the mechanism. However, it does not distinguish this tool from the sibling 'update_pet', which likely has a different input method.

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?

There is no guidance on when to use this tool versus alternatives like 'update_pet'. The description lacks any explicit context for appropriate usage or exclusions.

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