delete_virtual_account

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

No annotations are provided, so the description carries full burden. It discloses the destructive action ('delete') and adds a condition ('no payment activity'), which is useful. However, it omits details like permission requirements, irreversibility, or behavior when the condition is not met.

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 succinct sentence that front-loads the action and condition. It is efficient for its purpose, though it could be slightly improved by briefly mentioning the required parameter.

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 the simplicity of the tool (one parameter, no output schema, no annotations), the description provides the essential purpose and a key constraint. However, it lacks parameter explanation, error handling hints, and return value info, leaving gaps for a fully informed invocation.

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?

With 0% schema description coverage and no explanation of 'accountRef' in the description, the agent must rely solely on the parameter name. The description does not clarify that accountRef is the identifier for the virtual account to delete, adding minimal semantic value.

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 'Delete' and the resource 'virtual account,' with a specific condition 'that has no payment activity,' which distinguishes it from sibling tools like create_virtual_account or list_virtual_accounts.

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 implies when to use (delete an inactive virtual account) but does not provide explicit when-not-to-use or alternatives. It lacks guidance on prerequisites or consequences if the account has payment activity, leaving the agent to infer context from siblings.

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