get_data_pools_usage

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

Annotations already indicate read-only and non-destructive behavior. The description adds value by mentioning required permissions and availability restrictions, which are beyond what annotations provide. No contradictions.

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 concise with two sentences, including a permission note and endpoint path. The endpoint path is somewhat redundant but not overly verbose. Could be slightly tighter.

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?

The description gives a sense of output (breakdowns) but does not explain return format or pagination behavior despite pagination parameters. Given no output schema, more detail would be helpful for completeness.

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?

All parameters have clear descriptions in the input schema, so schema coverage is 100%. The description mentions 'with service line and monthly breakdowns' which hints at output but adds little to parameter understanding 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?

The description clearly states it queries data pool usage with service line and monthly breakdowns, specifying the resource and action. However, it does not differentiate from sibling tools like get_data_pools or post_data_usage_query, which could cause confusion.

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?

The description provides context on required permissions ('Service plan, View') and indicates it is a pre-release feature for select audiences. It lacks explicit guidance on when to use alternatives or when not to use this tool.

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