email_generate_system

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

With no annotations, the description carries full responsibility for behavioral disclosure. It indicates generation and a Pro requirement, but says nothing about side effects, file creation, overwrites, required external services, network calls, or whether the operation is reversible. For a code-generation tool, this is a significant transparency gap.

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 text is short and front-loaded, with no fluff. However, for a tool that generates a management system and requires two parameters including `api_key`, one sentence is under-specified rather than appropriately concise.

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?

There is no output schema, no annotation coverage, and a non-trivial two-parameter tool. The description omits outcome, return value, parameter semantics, side effects, and prerequisites. It is inadequate for an agent to invoke this tool with confidence.

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 coverage is only 50%: `directory` has a description but `api_key` does not. The tool description does not compensate for this, never mentioning `api_key` or clarifying what it is for. An agent cannot infer whether the key is for an email provider, a management API, or authentication to the feature itself.

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 clear verb and resource — "Generate email template management system" — so an agent knows this produces something related to email templates. However, "system" is vague: it does not say whether it scaffolds code, emits configuration, or provisions a service, and it only weakly separates this from siblings like email_generate_html and email_generate_react.

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 guidance on when to use this tool instead of related siblings such as email_generate_html or email_generate_react. The only qualifier, "Pro feature," hints at entitlement but does not explain the intended workflow or alternatives.

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