Behavior2/5

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

No annotations are provided, and the description is minimal, failing to disclose key behaviors such as pagination (continue_from), default/max limits, type filtering, or the nature of the returned list. The schema provides some info but the description should add this context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short (4 words) and under-informative. While front-loaded, it does not earn its place for a tool with pagination and filtering. A sentence or two is warranted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (4 parameters, pagination, type filtering, output schema), the description is far from complete. It omits pagination, filtering, and output structure details. The output schema exists but description should summarize return values.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so baseline is 3. The description does not add any extra meaning beyond the schema, which already describes each parameter adequately. No added value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get pages in a category' is a clear verb+resource, but it is slightly misleading because the tool also returns subcategories and files (as per member_type parameter). It distinguishes from siblings like get_page_tool (single page) and list_pages_tool (all pages) but could be more precise.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives. Siblings like get_page_categories_tool, list_categories_tool, and list_pages_tool perform related functions, but the description offers no differentiation or context for selection.

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