Book an appointment

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

No annotations provided, so description carries burden. Discloses that booking is real and subject to cancellation policy. Could add details about side effects or authorization needs, but adequate for basic transparency.

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?

Three sentences, each informative. No redundant text. Front-loaded with action and key constraint.

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?

Well-covered for a simple 3-param creation tool. Explains dependency on find_availability and real booking status. Missing output description but acceptable without output schema.

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 coverage 67% with startTime and providerId described. Description adds format and dependency for startTime but not for serviceId or providerId beyond schema. Baseline 3 with marginal value added.

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?

Clearly states 'Book an appointment' with specific verb and resource. Distinguishes from siblings like cancel_appointment and find_availability by noting that startTime comes from find_availability.

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?

Provides clear context: startTime must be from find_availability, end time computed automatically, creates real booking subject to cancellation policy. Does not explicitly exclude alternatives but implies prerequisite sequencing.

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