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 pagination behavior ('50 at a time, up to 200 via limit, continue with offset') and the returned fields, but with no output schema this is thin and largely retreads the schema's numeric bounds.

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?

Three sentences ordered as purpose, paging mechanics, then usage triggers — front-loaded and free of padding. The batching sentence is slightly long but every clause carries information.

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 supplies the return shape (titles and URLs) and the paging contract for a simple two-optional-parameter read tool. Nothing essential for a correct call is missing, though error/empty-result behavior is unspecified.

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 has to carry the load, and it does: limit is framed as batch size with a 200 cap, offset as the continuation cursor. That is enough for an agent to page correctly, though neither parameter's range semantics are stated exhaustively.

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 pages loaded in XR Memorandum') plus the returned fields (title and URL) and the scope of the corpus. It implicitly separates itself from search_pages with 'when you can't find it by searching', but never names a sibling explicitly.

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?

Gives two concrete trigger conditions: when you want to know what pages exist, and as a fallback when a search fails. That is real when-to-use guidance, though it stops short of naming search_pages/search as the preferred alternative in the normal case.

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