Behavior3/5

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

With no annotations, the description provides some behavioral transparency by stating no auth needed, but it does not disclose potential limitations, such as character limits on parameters or URL truncation behavior, nor does it describe the exact URL format returned.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence that conveys the purpose and key constraint (no auth) without wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

While the tool is simple (URL builder), the description lacks information about the return value (e.g., it returns a URL string) and does not specify constraints on parameter lengths or encoding, making it less complete than ideal.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 20% (only 'start' has a description 'ISO 8601'). The tool description does not add meaning for other parameters like 'location' or 'description', leaving their format ambiguous beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

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 Google Calendar' URL for an event, specifying no auth needed, which distinguishes it from sibling tools like create_calendar or create_event that require authentication.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly notes 'no auth needed', guiding agents to use this when they want a URL without authentication, contrasting with authentication-required tools. However, it does not specify when to avoid this tool or provide explicit alternatives.

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