removeAutoRenewal

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

No annotations are provided, so the description must disclose behavior. It states the mutating action but omits side effects, prerequisites, idempotency, what happens if auto-renewal is already off, and any auth/account requirements. The API reference link is generic.

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 concise sentence with the action front-loaded and an API reference link appended. Every word contributes, and there is no redundancy.

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 (one parameter, one action), so the description covers the primary purpose. However, without annotations or an output schema, the lack of behavior description (return values, edge cases, account requirements) leaves an incomplete picture for an autonomus agent.

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?

The schema has one required parameter 'domain' with a minimal description ('Domain'), achieving 100% schema coverage. This meets the baseline of 3, but the tool description adds no extra meaning beyond naming the parameter again.

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 action and resource: 'Turn off auto-renewal for a domain'. This clearly distinguishes it from the sibling addAutoRenewal and other domain management tools.

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: the tool is for disabling auto-renewal on a domain. However, there is no explicit mention of when to use it over addAutoRenewal or other domain lifecycle tools, and no exclusion criteria.

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