get_appointment_by_id

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

No annotations are provided, so the description carries the burden. It states the tool retrieves an appointment but does not disclose any behavioral traits like error handling, authentication requirements, or rate limits. The description is insufficient for a complete behavioral understanding.

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 short and front-loaded, using a clear sentence followed by bullet points for args and returns. It is efficient, though the args and returns sections could be more integrated.

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 tool has an output schema, so the description does not need to detail return structure extensively, but it mentions 'Dictionary containing the appointment information'. Despite many sibling tools, the description does not help distinguish when to use this one, and there is no mention of error scenarios. It is adequate for a simple retrieval.

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?

With 0% schema description coverage, the description adds meaning by labeling the parameter as 'The FHIR Appointment ID'. This clarifies the expected value beyond the schema's type string. However, it is minimal and does not specify format or constraints.

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 'Retrieve a specific appointment by ID', which specifies the verb (retrieve) and resource (appointment by ID). It is distinct from siblings like get_patient_appointments which retrieves all appointments for a patient.

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 search_appointments_by_date or get_patient_appointments. It only describes what the tool does, leaving the agent without context for selection.

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