create_appointment

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

No annotations are provided, so the description must convey behavioral traits. It mentions minimum fields required but does not disclose what happens on success (e.g., returns an ID), error handling, side effects, or idempotency. The reference to external documentation compensates slightly but falls short within the description itself.

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 consists of two concise sentences with no wasted words. The first states the purpose, and the second explains the parameter format. It is front-loaded and efficient.

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 simple creation tool with one parameter and an existing output schema (whose details are not needed in the description), the description provides adequate context. It explains the parameter format and points to external docs for full schema. It could mention return value briefly, but completeness is reasonable.

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 one parameter, appointment_json, with no description (0% coverage). The description adds significant meaning by specifying it is a JSON object string and listing the minimum required fields (PatNum, AptDateTime, etc.). This compensates well for the schema's lack of detail.

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 tool's purpose as 'Create a new appointment.' This verb+resource combination is specific and distinct from sibling tools like find_appointments and get_appointment, which are read-only operations.

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 implies the tool is for creating appointments, but it does not explicitly state when to use it versus alternatives, nor does it provide any exclusions or prerequisite conditions. The context is implied by the operation name, but explicit guidance is minimal.

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