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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds nothing behavioral beyond that: no note on what the page payload contains, caching/freshness, or the domain pinning's practical effect. The parenthetical is the only unique claim.

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, front-loaded with the resource name, with no filler. It is efficient, though the domain parenthetical is of marginal value.

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?

An output schema exists so return values need not be explained, and annotations cover safety. Still, for a detail-fetch endpoint the description omits how to obtain a handle (the key caller need) and any sibling routing, leaving a small but real gap.

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?

Only one parameter, and schema description coverage is 100% ('Required. Static page handle (URL slug).'), so the schema fully documents it. The description adds no additional meaning. Baseline 3 applies when the schema does the heavy lifting.

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 the resource (a static page detail) and pins the domain, but the verb is implicit ('detail') and there is no explicit contrast with the sibling ohpolly_pages list endpoint. An agent can infer it fetches one page, but the description does not distinguish it in words.

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 when-to-use guidance, no mention that a handle is required, and no pointer to ohpolly_pages or sitemaps as the way to discover handles. The agent gets no routing or prerequisite information.

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