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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds a small behavioral signal with '(public)', implying the invite link is publicly accessible and likely needs no special authentication, but it does not disclose what information is returned or any failure modes. This is modest added context beyond the annotations.

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, front-loaded sentence with no filler or repetition. It is concise, though it is also somewhat under-specified; this keeps it from receiving a 5 because the brevity comes at the cost of useful param and output context.

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?

With no output schema and no parameter documentation in the schema, the description carries the burden of explaining what information is returned and what 'token' refers to. It does neither. For a tool that an agent must invoke with a required token, this leaves the agent guessing about both input and output expectations.

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 has one required parameter, 'token', with no description, and schema description coverage is 0%. The tool description does not mention the token at all—neither its meaning, format, nor how to obtain it. The description completely fails to compensate for the schema's lack of parameter documentation.

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 states a clear action and resource: 'Get information about a clarity interview invite link (public).' It is more than a tautology and immediately signals what the tool does, but it does not explicitly distinguish itself from closely related siblings like getClarityProcessInviteLink or acceptClarityProcessJoin.

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 offers no guidance on when to use this tool versus alternatives such as getClarityProcessInviteLink, createClarityInviteLink, or acceptClarityProcessJoin. No context, prerequisites, or exclusions are provided, so the agent must infer usage from the name alone.

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