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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful behavioral context: it returns titles and URLs only, and it explicitly warns not to infer body content from titles/URLs. It says nothing about pagination behavior despite the limit/offset parameters, so it is helpful but incomplete.

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?

Purpose is front-loaded in the first sentence, which is good structure. The middle sentence listing content categories is long and enumerative, padding the definition, and the pagination parameters go unmentioned while category examples take up space.

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?

There is no output schema, so the description rightly explains that it returns titles and URLs. But for a paged listing tool with limit/offset parameters, the absence of any pagination guidance is a real completeness gap, and no alternative tool is offered for related needs.

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 0% for two parameters (limit, offset), so the schema provides no semantic help and the description carries the full burden. The description never mentions pagination, limits, or offsets, leaving an agent unable to know that results are paged or how to page through them.

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 states a specific verb and resource: it enumerates the titles and URLs of pages published on the Pono-Pono site and its purpose of grasping overall site structure. It further enumerates the content categories those pages fall into (product intro, FAQ/guide, brand concept, company overview, news, Journal), which sharpens what 'pages' means here. It does not explicitly distinguish itself from siblings like site_overview or search_pages, 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?

It gives implied usage: use it to understand the site's structure and to pick the page best matching a question, checking related pages as needed. However, no alternative tool is named (e.g., when to prefer search_pages or get_page), and there are no explicit when-not-to-use conditions. Usage is inferable but not spelled out.

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