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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds the return-field inventory, but says nothing about pagination, ordering, or scope limits for a list operation.

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?

Two short sentences with no filler, and the returned-field list is front-loaded. The second sentence is thin but functional rather than wasteful.

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?

No output schema exists, so the description correctly compensates by naming the returned fields. With one fully documented parameter and annotations covering the safety profile, only the missing sibling differentiation and pagination behavior keep it from being complete.

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?

There is one parameter with 100% schema description coverage ('Site id'), so the schema carries the burden. The description does not mention the site id at all, adding no meaning beyond the structured field; 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 and resource ('List the site's pages') and enumerates the returned fields (node id, name, slug, home/404 flags), which is more than a restated title. It does not, however, distinguish itself from close siblings like list_site_nodes or get_site_node.

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?

'Use it to get page ids' gives a use case but no when-to-use versus the many other list/get node tools in the sibling set. Usage is implied rather than scoped, leaving the agent to guess between list_pages, list_site_nodes, and get_site_node.

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