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

Annotations already declare readOnlyHint=true, so safety is covered; the description adds essentially nothing else. It does not say whether all pages are returned, whether results are paginated, or what a page entry contains — the main behavioral questions for a listing tool.

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?

A single front-loaded sentence with no filler. It is efficient, though the space saved could have carried useful listing or pagination context.

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 simple one-parameter read tool with annotations, this is close to sufficient, but with no output schema the description should hint at what the listing returns and whether pagination applies, and it should route agents away from list_docs when they need targeted lookup.

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%, but with a single optional parameter named "section" whose enum enumerates the valid values, the schema communicates the semantics on its own. The description adds only that the filter is optional and targets one section, which is marginal beyond the 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?

"List Druxt documentation pages" states a specific verb and resource, and the optional section scope distinguishes it from the single-item get_doc. It does not explicitly contrast itself with search_docs, but the list-vs-search distinction is inferable.

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?

"Optionally for one section" implies usage as a section-scoped or full listing, but there is no explicit when-to-use guidance and neither sibling (get_doc, search_docs) is mentioned as an alternative for query-based retrieval.

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