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

There are no annotations and the description provides no behavioral disclosure. It does not mention what authority metric is returned, whether this is a read-only operation, or any limits/requirements, leaving the agent with no information about runtime behavior.

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 short but under-specified rather than concise. The first phrase is redundant with the title, and the remaining billing/category note does not compensate for the missing functional explanation.

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?

Although this is a simple one-parameter tool, there is no output schema, annotations, or behavioral context to clarify what 'website authority' means or what the caller receives. The billing note is useful but insufficient for tool selection and invocation.

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 description does not mention the url parameter at all. The input schema provides a title 'Target URL' and an example, but the description adds no semantic value beyond that, despite the low schema description 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 opens with the exact title 'Website Authority Checker' and adds only a category and billing note. It does not state what the tool does in verb+resource terms, so it largely restates the name/title without conveying functional purpose.

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 given about when to use this tool versus sibling checkers like get_v1_website_traffic_checker or get_v1_backlink_checker. 'Link Building' is a broad category, not an explicit usage criterion.

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