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

No annotations are provided, so the description must disclose behavioral traits. It implies a read operation ('Get the status') but does not explicitly state read-only nature, side effects, or authentication details beyond requiring a key. Inadequate for a tool with no 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 short (one sentence), but it omits critical details such as parameter explanations and return value. It is terse, not efficiently informative.

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 lack of output schema, no annotations, and two parameters, the description is incomplete. It does not explain the return format, what 'status' entails, or how the URL is provided. Sibling tools are listed but not differentiated in usage context.

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 the parameters. It mentions 'key' but not the 'name' parameter, leaving its role ambiguous. The description does not compensate sufficiently for the missing schema descriptions.

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 specifies the verb 'Get', the resource 'status of one site', and adds clarifying examples 'exists / live URL'. It clearly distinguishes from sibling tools like list_sites (which lists all sites) and check_name.

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 states 'Requires a key', which is a usage prerequisite, but provides no guidance on when to use this tool versus alternatives like list_sites or check_name. Context is implied but not explicit.

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