undo_appointment_status

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

The description only states the primary action but omits behavioral details such as side effects, permissions required, reversibility, or error conditions. Since no annotations are present, the description should disclose more about the mutation behavior.

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, concise sentence that immediately conveys the tool's purpose with no extraneous words. It is efficiently front-loaded with the action.

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?

The description explains the core function but lacks completeness for a mutation tool with no output schema. It omits details such as return value, error conditions, and prerequisites (e.g., appointment must exist and have a status change to undo).

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 fully describes the single parameter ('id' as Appointment ID) with 100% coverage. The tool description adds no additional meaning beyond what the schema provides, meeting the baseline expectation.

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 specific action of undoing the latest status change for an appointment. It uses a precise verb ('Undo') and resource ('appointment status change'), differentiating it from siblings like delete_appointment (deletes entire appointment) and update_appointment (general update).

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 description does not provide any guidance on when to use this tool versus alternatives such as update_appointment or delete_appointment. No context about prerequisites, limiting conditions, or scenarios where this tool is preferred is given.

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