team_billing_info

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 indicates a read operation (non-destructive) but lacks details on authentication requirements, rate limits, error conditions, or required scopes. For a simple read with no parameters, this is acceptable but not thorough.

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 sentence of six words. It is extremely concise and front-loaded with the core purpose. Every word contributes meaning, with no redundancy or filler.

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 zero parameters and the existence of an output schema, the description minimally covers what is needed. It explains the tool's action and resource, and the output schema handles return value documentation. However, it could be improved by specifying that it reads the current workspace's billing info (implied but not explicit).

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 tool has zero parameters, so no parameter semantics to add. The schema coverage is 100% (vacuous). According to the rules, 0 parameters yields a baseline of 4. The description does not need to add anything about parameters.

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 tool's purpose: 'Read a workspace's billing plan information.' It specifies the action (read) and the resource (billing plan information) with a clear scope (workspace). This differentiates it from sibling tools like team_billable_info (which may focus on billable usage) and team_info (general info).

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 such as team_billable_info or team_info. The description implies it is for reading billing plan information but does not provide criteria for selection or note any prerequisites, making it minimally adequate.

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