set_auto_renew

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

Annotations already declare this is a non-destructive, idempotent, open-world mutation. The description adds meaningful behavioral context beyond that: it also controls renewal of the associated domain when the domain was bought at LWS. It does not cover permissions or timing consequences, but the added side-effect disclosure is valuable.

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?

A single sentence with zero filler, front-loading the action and resource. Every word earns its place.

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?

The tool is simple, has an output schema, and annotations cover the safety profile, so the description does not need to explain return values. It communicates the core effect and the domain side-effect, though it omits permission requirements and what happens to an existing renewal cycle when toggled off.

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 50%. The description clarifies that 'hosting' is the hosting whose renewal is toggled and ties it to its domain, adding some meaning. However, the 'enabled' parameter is only implicitly described by 'on or off' and receives no explicit true/false semantics beyond what the boolean schema already conveys.

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 ('Turn ... on or off') and resource ('automatic renewal of a hosting (and its domain, if bought at LWS)'), making the effect unambiguous. It does not explicitly differentiate from siblings, but no sibling tool overlaps with this purpose, so the omission is minor.

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?

Usage is implied by the toggle wording: use it when you want to enable or disable auto-renewal. There is no explicit when-to-use guidance, no prerequisites, and no named alternative, though no alternative sibling exists.

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