cpanel_email_create

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

With no annotations provided, the description carries full burden for behavioral disclosure, but it only states 'Create a new email account'. It fails to mention effects like modifying cPanel settings, required permissions, or success/failure behavior. No output schema is provided to compensate.

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, front-loaded sentence of 10 words, which is highly concise and free of fluff. However, it sacrifices necessary detail for brevity, earning a slightly lower score.

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 the tool has 5 parameters, no output schema, and no annotations, the description is insufficient. It omits return values, error scenarios, prerequisites, and post-creation state, leaving the agent without critical information for correct invocation.

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 input schema has 60% description coverage (3 of 5 parameters have descriptions). The tool description itself adds no extra meaning to parameters; it simply repeats the creation intent. Two parameters (cpanel_user, password) lack schema descriptions and are not explained in the description, leaving gaps for the agent.

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 'Create a new email account for a cPanel user', which uses a specific verb (create) and resource (email account). It distinguishes itself from sibling tools like cpanel_email_list (list) and cpanel_forwarders_list (forwarders), making its purpose unambiguous.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or conditions. For example, it doesn't clarify that the cPanel user must already exist or that the email address must be unique.

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