get_events_for_date

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

No annotations are provided, so the description carries the full burden. It does not disclose any behavioral traits beyond the basic read operation, such as auth requirements, rate limits, or whether the calendar event list includes all-day events. It merely restates the function.

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 with no unnecessary words. It uses a structured format (Args/Returns) that is easy to scan. Every sentence is necessary.

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 simplicity of the tool (2 parameters, no nested objects), the description provides adequate information. However, it could include details like timezone handling or the format of the returned events list, though the output schema is available to supplement. Overall, it is minimally sufficient.

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 0%, so the description must add value for parameters. It specifies the date format (YYYY-MM-DD) and the default for calendar_id. However, it does not explain the meaning of the parameters beyond what the schema already provides (type string). This is minimal but acceptable.

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 'Get calendar events for a specific date', which is a specific verb+resource. Sibling tools 'get_upcoming_events' and 'search_events' are distinguished by the focus on a single date.

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 explicit when-to-use or when-not-to-use guidance is provided, but the purpose is clear enough that an agent can infer usage. Without differentiating advice like 'for a range of dates use search_events', the score is average.

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