Get Billing Account Details

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

No annotations are provided, so the description carries the behavioral disclosure burden. It does convey that this is a read-only retrieve operation, but it does not disclose expected permissions, error behavior, or what the returned 'detailed information' includes. This is a minimal but not rich behavioral description.

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, front-loaded sentence with no redundant clauses or filler. Every word contributes to identifying the operation and its target resource.

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 one-parameter getter with complete schema coverage, the description is workable, but it lacks any detail about the response contents and gives no usage context. Since there is no output schema and no annotations, a bit more description of what details are returned would make it complete.

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?

Schema description coverage is 100%, so the input schema fully documents the only parameter, including a concrete example format. The description adds no parameter-specific meaning, which is acceptable because the schema already handles it.

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 uses the specific verb 'Retrieve' with a clearly identified resource, 'a specific Google Cloud billing account,' and the word 'specific' signals it targets one account rather than a list. It does not explicitly distinguish itself from siblings like gcp-billing-list-accounts or gcp-billing-get-project-info, but the resource and scope are clear.

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 phrase 'specific billing account' implies this tool is for looking up one account rather than listing accounts, but the description gives no explicit when-to-use guidance and names no alternatives. An agent must infer the distinction from the resource wording.

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