get_calendar_virtual_members

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states the tool retrieves virtual members from an endpoint, implying a read operation, but does not explicitly confirm safety or disclose any side effects, rate limits, or authorization requirements. The lack of detail is a significant gap for a tool with zero annotations.

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 a single sentence that immediately conveys the core purpose. It is concise, front-loaded, and contains no redundant or irrelevant information.

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 a simple retrieval tool with two parameters and no output schema, the description is minimally adequate. However, it does not cover expected behavior like response format, error handling, or pagination. Given the lack of annotations, a bit more detail would be beneficial, but it is not critically incomplete.

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% with both parameters having basic descriptions. The tool description itself does not add any parameter-related information beyond the schema. According to guidelines, high coverage leads to a baseline of 3, and there is no additional value contributed by the description.

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 clearly states the action ('Get'), the resource ('TimeTree virtual members'), and the scope ('for a calendar'). It effectively distinguishes itself from sibling tools like 'get_calendar_members' by specifying 'virtual members'.

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 does not provide guidance on when to use this tool versus alternatives, such as when to choose it over 'get_calendar_members'. There is no mention of prerequisites, context, or exclusions. The bare description leaves the agent to infer usage without explicit direction.

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