MarathonUnsetModeratorsForPupil

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

Annotations already flag destructiveHint=true, but the description adds meaningful context beyond that: it states that moderators are unlinked from the pupil and that client-side approval is required. This helps an agent understand the real-world consequence and prerequisite before invoking the tool.

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 extremely concise: one clear action sentence followed by a warning sentence. Every word earns its place, and the destructive warning is front-loaded for visibility.

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 two-parameter destructive operation with annotations and full schema descriptions, the description covers the core action, its destructive nature, and the approval requirement. It does not describe return values or further side effects, but for this simple mutation with no output schema, the provided context is largely sufficient.

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%, so the parameters are already documented with meaningful descriptions in the input schema. The tool description does not add further parameter-level detail, so the baseline 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 uses a specific verb and resource: 'Unassign moderators from a marathon pupil.' This clearly identifies the action and object, and it distinguishes the tool from siblings like MarathonSetModeratorsForPupil and MarathonUnsetPupilsForModerator by stating the direction of the operation.

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 verb 'Unassign' and the resource phrase, but there is no explicit statement about when to choose this tool over alternatives such as MarathonSetModeratorsForPupil or MarathonUnsetPupilsForModerator. It provides clear context for the operation but no explicit when/when-not guidance.

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