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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful behavior beyond annotations: the question is backed by Cal.com and requires the creator to connect Cal.com and select an event type afterward, signaling external setup dependency. It does not detail side effects or permissions beyond that, so it is strong but not exhaustive.

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, front-loaded with the core action and immediately followed by usage guidance and the Cal.com dependency. Every sentence earns its place with no filler or repetition.

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 an insert-question tool with full schema coverage and annotations covering safety, the description is nearly complete: purpose, sibling differentiation, and external setup are all present. The only minor gap is that it does not mention what happens if Cal.com is not connected or how the inserted question behaves before setup, but those are secondary for an agent selecting the tool.

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 the schema fully documents all 8 parameters, including insertion mechanics like after, parentId, and position. The description adds no parameter-level meaning beyond what the schema already provides, so baseline 3 is appropriate.

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 (Insert) and resource (Schedule appointment question) and scopes it to Cal.com-backed bookings or appointments. It explicitly distinguishes this from separate date and time questions, which are sibling tools (editor_insertDateQuestion, editor_insertTimeQuestion), so an agent can identify the correct tool without opening the schema.

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?

It gives explicit when-to-use guidance ('Use for bookings or appointments') and a clear when-not rule ('do not substitute separate date and time questions'). It also notes the post-insert requirement that the creator connects Cal.com and selects an event type afterward, which routes the agent away from this tool if no Cal.com setup is intended.

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