Get Workspace Billing

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

The annotations already declare readOnlyHint=true and destructiveHint=false, which cover the main behavioral aspects. The description adds nothing beyond 'get info', which aligns with the read-only nature. Since the annotations carry the burden, a score of 3 is appropriate.

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 no unnecessary words. It is front-loaded with the verb 'Get' and immediately states the resource, making it highly efficient and well-structured.

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 output schema, the description is minimally sufficient, but it lacks essential context such as usage guidance vs. account billing or any detail about what 'billing info' includes. It is not completely self-contained for an agent to decide when to use it.

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 only defines workspaceSlug as a string without further description. The description does not mention or clarify this parameter. Although the name is self-explanatory, the low schema coverage (0%) means the description should compensate, but it does not.

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 the resource 'workspace billing info', which is specific. It does not explicitly differentiate from sibling tools like getAccountBilling or getUserBillingState, but the tool name itself indicates the workspace scope, so it is clear enough.

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 no guidance on when to use this tool versus alternatives such as getAccountBilling or changeBillingPlan. There is no mention of context, prerequisites, or when not to use it, leaving the agent to infer usage solely from the name.

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