ruddur_get_creator_billing

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

The description adds the required scope 'billing.read', which is valuable context beyond the annotations. Since readOnlyHint=true and destructiveHint=false already indicate a safe read operation, the description's contribution is modest but not contradictory.

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, focused sentence with no filler or redundancy. It communicates the core purpose and a key prerequisite efficiently.

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 getter with no required parameters and good annotations, the description is minimally sufficient. However, it does not clarify what the billing summary contains, which creator it refers to, or how to use optional query/body parameters. The absence of an output schema increases the need for such context.

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 input schema has descriptions for both 'body' and 'query', achieving 100% coverage. However, the descriptions are generic (e.g., mentioning POST/PUT/PATCH) and not tailored to this getter tool. The tool description itself provides no additional parameter meaning, so a baseline score of 3 is appropriate.

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 action ('Get') and resource ('creator billing summary'), distinguishing it from sibling tools like analytics or profile getters. It is more specific than a tautology, though it could benefit from elaborating what the summary includes.

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 guidance is provided on when to use this tool vs alternatives such as ruddur_get_creator_analytics or ruddur_get_creator_profile. The only additional information is the required OAuth scope, which is a prerequisite, not a usage guideline.

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