get_dimensions_by_category

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

No annotations are provided, so the description carries the full burden. It states it retrieves 'all dimensions' with descriptions, implying a read operation, but lacks details on authentication, rate limits, or pagination. For a simple retrieval tool, it is minimally adequate.

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 very concise: two sentences plus an args line. The first sentence front-loads the purpose, and every word adds value without redundancy.

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?

Given the tool's simplicity (one parameter, no output schema), the description is fairly complete. It explains the input and output. However, it does not specify the exact return format (e.g., list of objects), but this is inferred from 'with their descriptions'.

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?

The schema has 0% coverage with no description, but the tool description adds a clear meaning for the 'category' parameter: 'The category name to retrieve dimensions for.' This clarifies the parameter's purpose, though it could specify sources for valid category names.

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 clearly states the verb 'Get' and resource 'dimensions in a specific category', and mentions that it includes descriptions. It distinguishes from siblings like get_metrics_by_category which deals with metrics, and list_dimension_categories which lists categories.

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?

No explicit guidance on when to use this tool versus alternatives. For example, it does not mention that for metrics one should use get_metrics_by_category, or that list_dimension_categories provides available categories.

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