Update Service Appointment

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

No annotations exist, so the description must disclose behavioral traits. It only states 'Update fields', implying mutation, but omits details on idempotency, side effects, permissions, failure behavior, or return value. This is a significant gap 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 extremely concise (one sentence) and front-loaded. However, it sacrifices necessary detail. While no filler exists, the brevity undermines usefulness, making it merely adequate for a trivial tool.

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?

Given the tool's complexity (7 parameters, nested objects, no output schema, no annotations), the description is critically incomplete. It fails to explain return values, allowed status values, default behaviors, or relationship to other tools. Major gaps exist.

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 low (29%), and the description adds no parameter semantics beyond what the schema provides. All seven parameters remain under-documented, with no examples, allowed values, or format guidance. The description should compensate but does not.

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?

Description uses verb 'Update' with resource 'Service Appointment' clearly indicating the action and object. It distinguishes from create/schedule tools among siblings. However, it lacks specificity about which fields beyond 'fields', leaving some ambiguity.

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 usage guidance is provided. The description does not mention when to use this tool versus alternatives (e.g., create_appointment, schedule_appointment) or any prerequisites. The one-sentence description is insufficient.

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