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

With no annotations, the description must carry the behavioural burden. It does disclose that results are ordered and paged and enumerates some returned fields (identifiers, languages, state dates, document types), but it omits defaults, page size behaviour, sort order, and whether the operation is read-only (implied by 'browse' but not stated).

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?

It is a single sentence with no filler, but the syntax is convoluted and front-loads an awkward fragment ('The Luxembourg works this mount holds') rather than a clear verb-resource statement. Size is appropriate; structure is weak.

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 four-parameter, unannotated, no-output-schema tool, the description gives a reasonable summary of what is returned and that results are paged. It is missing key context an agent needs: the meaning of 'this mount', the semantics of `after`, default and maximum page sizes, and ordering guarantees.

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 all four parameters. The description only indirectly names two of them ('filter by type or language') and gestures at paging with 'ordered and paged', without explaining what `after` is (cursor? identifier?), what the default `limit` is, or how ordering relates to `after`. It compensates only partially for the coverage gap.

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 identifies a concrete resource: the Luxembourg works held by 'this mount', described as an ordered, paged list with identifiers, languages, state dates and document types. That is a specific, recognisable listing operation, though the sentence fragment style ('The Luxembourg works this mount holds') and absence of any contrast with sibling tools like search or timeline keep it from 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 says 'filter by type or language', which hints at usage, but never states when to choose this over siblings such as search, timeline, or coverage. There are no exclusions and no prerequisites mentioned.

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