PupilsCreate

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

The description is consistent with annotations (readOnlyHint: false, idempotentHint: false, destructiveHint: false) but adds little beyond what the annotations already convey. It does not mention return behavior, duplicate handling, required email validation, permissions, or side effects.

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 one short, front-loaded sentence with no filler or redundant elaboration. It is concise and easy to parse, though it is so minimal that it borders on restating the tool name.

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 rich schema and annotations, the description is sufficient for selecting the tool for a straightforward create operation. However, it lacks context about the response format, failure conditions, or how this create operation relates to the broader Pupils toolset, which would make it more 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 input schema has 100% coverage with descriptions for all 16 parameters, so the baseline is 3. The description itself adds no parameter-level meaning; all semantic weight is carried by the schema, which is sufficiently detailed.

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 operation (create) and the resource (pupil), which distinguishes it from sibling tools like PupilsGetList, PupilsUpdate, and PupilsDelete. However, it is minimal and does not specify any additional scope or nuances beyond the simple verb–resource pair.

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 provided about when to use this tool instead of related tools such as PupilsUpdate or MarathonAddMarathonNewStudents. The description relies entirely on the verb 'Create' to imply usage, with no explicit alternatives or conditions.

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