get_calendar_events

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

With no annotations provided, the description must fully disclose behavioral traits. It only states the basic fetch action and time range, without addressing potential side effects, permissions, rate limits, or response characteristics. This leaves significant uncertainty for the agent.

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 one concise sentence that front-loads the core action. The parenthetical '(using accli)' is slightly cryptic and does not add meaningful value for the agent, but the overall structure is efficient.

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 two-parameter read tool, the description is adequate but lacks clarity on what the returned data looks like (e.g., event objects, count, ordering) since no output schema is provided. There is also no mention of error cases or restrictions. The description is minimally sufficient but not rich.

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 input schema already provides 100% coverage with clear descriptions for both 'from' and 'to' parameters. The description adds no additional parameter-specific details, so it meets the baseline for high schema coverage.

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 uses a specific verb "Fetches" with a clear resource "calendar events" and a scoping condition "for a given time range". This distinguishes it from sibling tools like create_calendar_event and list_calendars, making the purpose unambiguous.

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 the tool is for retrieving events within a specified time range, which provides some context. However, it does not explicitly mention when to use it versus alternatives such as create_calendar_event or list_calendars, nor does it state any exclusions or prerequisites. The guidance is 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.
