findPetsByStatus

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

No annotations are supplied, so the description carries the full behavioral burden, yet it discloses nothing about authentication needs, pagination/result limits, whether results are sorted, or what an empty result means. Even the basic fact of how the status filter behaves is absent.

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?

It is short and front-loaded, but that brevity reflects under-specification rather than economical writing; there is only one sentence and it earns its place only as a name restatement.

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 required, undocumented string parameter with no output schema and no annotations, the description should at minimum state valid status values and the shape of the result. None of that is present, leaving the agent unable to construct a correct call.

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 description coverage is 0% and the single parameter is an opaque string called "kwargs", which gives no hint that it should carry a status value. The description says nothing about the parameter, so an agent cannot know the accepted key name, format, or valid status values (no enums are declared).

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?

"Finds Pets by status" is a verbatim restatement of the tool name findPetsByStatus with spaces inserted, so it adds no information beyond the identifier. It does imply a status filter (loosely distinguishing it from getPetById), but an agent learns essentially nothing it did not already know from the name.

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 when-to-use guidance: nothing says whether this is meant for listing multiple pets versus the single-pet getPetById sibling, nor when it should be preferred over the unrelated siblings (db_sample_query, exec_curl, etc.). No exclusions or alternatives are named.

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