get_calendly_user

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

The description does not disclose behavioral traits beyond the 'get' verb. With no annotations, valuable details like read-only nature, authentication prerequisites, rate limits, or response structure are absent, leaving the agent without important context.

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, clear sentence that immediately conveys the tool's purpose. It is front-loaded and contains no extraneous information, earning a top score for conciseness.

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 profile retrieval tool with one optional parameter and no output schema, the description is minimally adequate. However, it could mention what fields are returned (e.g., name, email) to reduce ambiguity, especially given no output schema.

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?

The schema has 100% coverage for the sole parameter 'api_key', so the description does not need to add much. The description does not elaborate on the parameter, but the baseline score of 3 is appropriate since the schema already documents it sufficiently.

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 tool retrieves the authenticated Calendly user profile, with a specific verb ('Get') and resource ('authenticated Calendly user profile'), distinguishing it from siblings like get_calendly_event or list_calendly_* tools.

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 guidance is provided on when to use this tool versus siblings. There is no mention of prerequisites or context for selecting this tool over others, which is a gap given the presence of multiple Calendly tools.

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