Create Appointment Group

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

Annotations already disclose destructiveHint=true and openWorldHint=true, so the safety profile is partially covered. The description adds domain context and clarifies the sign-up slot concept, but it does not disclose persistence effects, permissions, return behavior, or how appointment creation interacts with existing scheduling data. No contradiction with annotations was found.

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?

Two focused sentences with zero filler. The description front-loads the action and audience, and quickly guides required inputs. It earns its space without redundancy.

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 11 parameters, 2 enums, and no output schema, the description covers the core workflow adequately by naming the required parameters and example slot format. It could have explicitly stated what the API returns or directed users to update_appointment_group for changes, but the existing schema and sibling names fill most of the gap.

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%, and each parameter already has a meaningful description, including new_appointments as [start_at, end_at] pairs. The tool description reinforces these points but doesn't materially add beyond the schema—it just restates the requirement for at least one context_code, a title, and the new_appointments format.

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 states a specific verb and resource: 'Create a new appointment group (sign-up slots) in Canvas Scheduler.' This clearly identifies the action and object, and distinguishes it from sibling tools like update_appointment_group, get_appointment_group, and list_appointment_groups.

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 when to use it — when creating a new appointment group — but does not explicitly compare it with alternatives such as update_appointment_group for modifying existing groups. There are no when/when-not statements, so usage remains implied rather than explicit.

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