enable_email_hosting

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

With no annotations provided, the description carries the full burden of explaining behavioral consequences. It only says 'Enable' without disclosing side effects, reversibility, prerequisites, or whether this modifies DNS records or domain settings. This is insufficient for a state-changing operation.

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 no filler or redundancy, and the action is front-loaded. However, it is concise at the expense of necessary context, so it is not a model of well-structured helpfulness.

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?

Despite having only two required parameters, the description omits essential context: what enabling email hosting entails, what zoid means, prerequisites, and how this differs from related domain tools. The presence of an output schema does not compensate for these gaps.

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 description adds almost no parameter meaning. 'domain' weakly maps to domain_name, but zoid is completely unexplained. An agent cannot determine what zoid refers to or what valid values look like.

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 ('Enable') and a clear target ('email hosting for domain'), so the core purpose is understandable. However, it does not distinguish itself from sibling tools like add_domain or verify_domain, so an agent may not know which domain-related operation to select.

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?

No guidance is provided about when to use this tool versus alternatives such as add_domain, verify_domain, or set_primary_domain. There are no prerequisites, exclusions, or alternative tool mentions, leaving the agent to guess the appropriate context.

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