Delete Billing Period

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

The description adds value by emphasizing irreversibility, but contradicts the annotation idempotentHint=true (deleting an already deleted resource likely errors). Annotations already provide destructiveHint=true, so the description adds limited new behavioral context.

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 fairly concise but repeats 'This cannot be undone' twice and includes redundant API endpoint info. It could be more streamlined without losing clarity.

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 no output schema and 2 well-described parameters, the description provides adequate context including the API endpoint. However, it lacks details on return values or potential side effects beyond the deletion itself.

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 coverage is 100%, so both parameters are described in the input schema. The description only reiterates that they are required, adding no extra semantic meaning beyond what is already in the schema.

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 (delete) and the resource (billing period), but repeatedly mentions 'Commitments' which may cause slight confusion about what is actually being deleted. Distinguishes from sibling tools like create_billing_period or list_billing_periods.

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 indicates this tool is for permanent deletion and cannot be undone, providing a clear when-to-use. However, it does not specify when not to use it or suggest alternatives like updating instead.

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