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

With no annotations, the description carries the full burden, and it only implies a read via the verb 'Get'. It does not state whether authentication or a specific permission scope is required, nor what happens when site_id is invalid or unknown. It does at least disclose the shape of the returned data, which is the main behavioral value here.

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?

A single short sentence with the resource, scope, and returned fields front-loaded. Every clause earns its place and nothing is padded.

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?

For a one-parameter read tool with no output schema, the description covers the key returned fields and the single-site scope, which is close to sufficient. It could still mention error behavior for unknown IDs or any permission requirement.

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?

Schema description coverage is 100% and there is only one parameter (site_id) whose schema description is simply 'The site ID.' The description adds no format, source, or syntax hints beyond what the schema already states, so the baseline 3 applies.

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?

States a specific verb (Get) and resource (details for one site) and enumerates the payload (languages, translation config, domain), which is helpful since there is no output schema. It does not differentiate itself from the sibling My_Sites, so it stops short of a 5.

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 phrase 'for one site' plus the required site_id implies this is the lookup to use once you already know a site ID, as opposed to My_Sites which presumably enumerates them. However, no sibling is named and there is no explicit when-to-use or when-not-to-use statement.

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