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

Annotations already cover the safety profile (readOnly, non-destructive, non-open-world). The description adds real behavioral context beyond them: batch size of 50, a maximum of 200 via limit, and offset-based continuation. Return content (titles and URLs) is also disclosed, though rate limits or ordering guarantees are unstated.

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 well-formed sentences, front-loaded with the resource and return fields, then pagination, then usage. No filler, though the service URL and full product name add length that could be trimmed.

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 2-param, no-required, no-output-schema tool, the description covers return shape, pagination mechanics, and usage intent adequately. Minor gaps (result ordering, total count behavior) remain but are not essential to correct invocation.

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 must carry parameter meaning. It does: limit default/max (50/200) and offset for pagination are explained in prose, compensating for the bare schema. It doesn't explicitly note offset units or ordering, so not a 5.

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 (returns a list of loaded pages with title and URL) within a named service context. It implicitly distinguishes itself from search-type siblings by framing this as the enumeration fallback, so an agent can tell it apart from search_pages/search.

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?

Explicitly says when to use it: to see what pages exist, or when a search fails to find something. This routes the agent away from search tools in the failure case. It does not state exclusions or name a specific alternative tool, keeping it just short of a 5.

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