List a category's members

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, so the safety profile is covered. The description adds that the result includes both articles and subcategories, but it does not disclose pagination behavior, ordering, whether subcategories are direct-only, or behavior for nonexistent categories.

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?

The description is a single concise sentence with illustrative examples, and the core content type is front-loaded. It is efficient, though the lack of an explicit verb in the description means it relies partly on the title for action clarity.

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 listing tool with read-only annotations, the description is minimally adequate, but without an output schema it does not explain the exact return shape, pagination mechanics, or edge cases. The cursor and category prefix are only covered via the schema rather than in a way that gives the agent operational confidence.

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 67%: category and cursor are documented in the schema, while limit is not. The description itself adds no parameter-level meaning beyond illustrative category examples, so it does not compensate for the missing limit documentation.

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 title and description make clear this tool lists the articles and subcategories belonging to a category, with concrete examples. It does not explicitly contrast itself with sibling tools like get_page_categories, so it lacks the sharp sibling differentiation of the highest tier.

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?

There is no guidance on when to use this tool versus alternatives such as get_page_categories or search_wiki. The examples show plausible category names but do not state a use case, exclusions, or conditions that would route an agent to a different tool.

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