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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds only the useful 'all settings at once' batching note; it says nothing about auth requirements, caching, or response size, so it clears the lowered bar without adding much.

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?

One tight sentence with the resource and the returned field list front-loaded; no filler. Slightly reduces clarity by burying the 'all at once' batching point after the verb, but it is efficient.

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 read-only getter with full schema coverage and annotations covering safety, the description's field enumeration is enough to call it correctly, and no output schema is needed. The remaining gap is differentiation from wp_get_site_info.

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 site_id is fully documented in the schema, including the 'optional if you have only one connected site' nuance. The description adds nothing about the parameter, so 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?

Clear verb+resource ('Get ... WordPress site settings') with a parenthetical enumeration of the settings returned, so an agent knows exactly what comes back. It does not differentiate itself from the nearby wp_get_site_info sibling, which could plausibly overlap, 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 description gives no when-to-use context, no prerequisites, and no routing against wp_get_site_info or wp_update_settings. An agent must infer from the name alone whether this or wp_get_site_info is the right read call.

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