Create Service Appointment

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

No annotations are provided, so the description must cover behavioral traits. It only states that it creates and optionally assigns fields, but lacks details on side effects, required permissions, or constraints (e.g., work order must exist). Insufficient for a mutation 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 very concise (one sentence, 18 words). It front-loads the core purpose. However, given the tool has 6 parameters, a bit more detail could be included without being verbose.

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 is too brief for a tool with 6 parameters, nested objects, no output schema, and no annotations. It does not explain return values, entity relationships, or how the appointment integrates with the work order lifecycle.

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 baseline is 3. The description adds minimal value by mentioning 'optionally assigning a technician and a scheduled start/end time', which maps to technician_id, scheduled_start, and scheduled_end. It does not explain summary, work_order_id, or additional_fields beyond what the schema already provides.

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 the action (Create), the resource (Service Appointment), and the context (for a Work Order). Optionally mentions technician and scheduling, distinguishing it from sibling tools like update_appointment or schedule_appointment.

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?

No explicit guidance on when to use this tool versus alternatives such as schedule_appointment or assign_best_technician. Does not indicate prerequisites or when not to use.

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