get_pet

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

The description adds only '[GET]', which mostly duplicates the safety information already provided by annotations such as readOnlyHint=true, idempotentHint=true, and destructiveHint=false. It does not disclose additional behavioral details like missing-ID handling, authentication requirements, rate limits, or response shape; the annotations do the heavy lifting.

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, front-loaded sentence with no filler or redundant elaboration. For a simple one-parameter read operation, this is appropriately compact and easy to scan.

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?

For a one-parameter, read-only get operation, the description plus annotations may be minimally sufficient, but the agent is left to infer too much from the tool name and parameter name. Missing guidance on what petId represents, how to handle nonexistent pets, and what a successful response looks like keeps this from being 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 sole required parameter petId has an empty schema description (0% coverage), and the tool description does not explain that petId identifies which pet to fetch or how it should be interpreted. The parameter name is suggestive, but the description adds no semantic value beyond what the schema already exposes.

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 states a clear verb ('Get') and resource ('a single pet'), which unambiguously conveys the operation and distinguishes it from list_pets by emphasizing singular retrieval. It does not explicitly contrast with siblings or mention the petId parameter, but the core purpose is clear.

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 word 'single' implies this tool is for retrieving one specific pet rather than listing pets or vaccinations, so usage context is indirectly suggested. However, there is no explicit statement of when to use this tool versus list_pets, no prerequisites, and no mention of alternatives.

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