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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so the safety profile is covered. The description adds useful context by naming the returned fields and topic structure, but says nothing about pagination or result-size behavior despite limit/offset existing.

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?

Front-loads what the tool returns in the first sentence, then gives concrete topic examples and a usage cue. Two sentences with no filler; appropriately sized.

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?

With no output schema, the description correctly explains the return shape (titles and URLs). However, for a parameterized listing tool it omits any pagination guidance, leaving a gap an agent would need when result sets exceed the default limit.

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%, so the description should compensate for the limit/offset parameters, yet it never mentions paging, defaults, or ranges. With 2 undocumented parameters the description leaves the agent to infer pagination entirely from the raw schema.

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 (list) and resource (pages loaded into 'Koekatsu') with what is returned (titles and URLs). The topic-category examples make the scope concrete, though it never explicitly distinguishes itself from siblings like search_pages or site_overview.

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?

Provides a context cue — 'use when you want to narrow by field and line up surveys' — which implies a filtered-listing use case. But it offers no explicit when-not-to-use and does not name any sibling alternative such as search_pages.

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