create_calendar_link

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

No annotations are present, and the description does not disclose any behavioral traits such as side effects, authentication requirements, or whether the tool is idempotent. Since it generates links (a read-like operation), this is less critical, but the description still fails to mention that it does not create actual calendar events.

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 with no unnecessary words. It is efficient and front-loaded with the key action and supported calendars.

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 5 parameters with full schema coverage but no output schema, the description is adequate but lacks detail on the return value (e.g., it generates links but does not specify the format or that links are returned). It is sufficient for a straightforward link generation tool but could be improved.

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 covers 100% of parameters with descriptions, so the baseline is 3. The tool description adds no additional meaning beyond the schema, simply restating the function. No extra context like constraints or examples is provided.

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 it generates add-to-calendar links for Google Calendar and Outlook, using a specific verb 'generate' and a specific resource 'add-to-calendar links'. This distinguishes it from sibling tools like create_event, which actually creates events.

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 alternatives like create_event or find_meeting_slots. There is no mention of context or exclusions, leaving the agent to guess which tool is appropriate.

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