MarathonGetModerators

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds only the 'paginated' behavior; it does not disclose ordering, default page size, or how filters interact with results, but this is acceptable given the annotations.

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?

A single front-loaded sentence with no filler; every word ('List', 'marathon moderators', 'paginated') carries information. This is an appropriate size for the tool's simplicity.

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 read-only list tool with no output schema, the description gives the high-level return shape but omits how the optional filters (TeacherId, MarathonId) affect the result, pagination defaults, and any response fields. Since all parameters are optional, an agent can call it safely, but a richer description would make correct filter usage obvious.

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 100%, giving the baseline of 3 even though the schema descriptions are only 'integer (optional)'. The word 'paginated' adds meaning to pageSkip/pageTake, but TeacherId and MarathonId filter semantics are left to inference from their names.

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?

States a specific action and resource ('List marathon moderators') and adds the pagination trait, which is enough to distinguish it from sibling mutators and from MarathonGetMarathonStudents. It does not explicitly contrast with any sibling, but the resource term is unambiguous.

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 intended use is implied by the listing verb and resource, but there are no explicit when-to-use conditions, exclusions, or pointers to alternative tools. An agent can infer 'when you need moderators' but not when a sibling like MarathonSetModeratorsForPupil should be chosen.

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