outlook_calendar_url

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

Without annotations, the description solely implies a read-only operation generating a URL. It does not clarify side effects, authentication, or output details, but the behavior is straightforward from the name and description.

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 single sentence is concise and front-loaded, but given the tool's simplicity, it is under-specified. Additional parameter or usage details would improve completeness without sacrificing 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?

The tool has no output schema, no annotations, and zero parameter coverage. The description does not explain the URL format, date string requirements, or any constraints, making it inadequate for an agent to invoke correctly.

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?

With 0% schema description coverage, the description should explain input parameters. It does not mention any of the five properties (title, start, end, etc.) or their formats, leaving agents without guidance beyond schema names.

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 builds a 'one-click Add to Outlook Web Calendar URL', specifying the verb, resource, and distinguishing it from sibling tools like google_calendar_url that build similar URLs for other platforms.

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 on when to use this tool versus alternatives (e.g., create_event vs. URL builder). The description omits context like when generating a URL is preferable to directly creating an event.

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