service_backups_enable_backups

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

Annotations already declare this non-read-only, destructive, open-world and non-idempotent, so the key safety signals are covered. The description adds nothing beyond them: it does not say whether enabling is billable, whether it silently replaces an existing schedule, or how failure mid-enable behaves.

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?

It is short and front-loaded, but over-terse rather than economical: the second line just restates the HTTP route and displaces information the agent actually needs about inputs and effects.

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 destructive, potentially billable mutation with a required nested body object, no output schema, and zero parameter documentation, the description leaves the agent unable to call it confidently. It needed to explain the body payload and the consequences of enabling backups.

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 0% and the body's nested 'method' field is described only as 'payment method to use', which is unintuitive for an enable-backups call. The description could have explained what the body must contain and why a payment method is needed, but instead contributes only the path template already implied by the schema's serviceId.

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 states a specific verb and resource ('Enable backups') and the endpoint clarifies this acts on a single service. However, it offers no scope or effect detail, so the distinction from siblings like service_backups_disable_backups rests entirely on the tool name rather than any stated difference.

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?

There is no when-to-use or when-not-to-use guidance, no mention of prerequisites such as an existing payment method or the relationship to service_backups_disable_backups, and no note about cost or scheduling interactions.

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