Create Company-Level Email Communication

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

Discloses that the tool dispatches the message and returns a confirmation, and that repeated calls may resend. Adds value beyond annotations, which already indicate non-read-only and non-destructive behavior.

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?

Concise with four sentences covering purpose, warnings, required params, and API reference. No unnecessary content, though the API endpoint could be considered extra detail.

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?

Lacks explanation of the return value structure and does not detail the expected fields inside the nested objects. Given no output schema, more information about the response would improve completeness.

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 100%, so baseline is 3. The description only lists parameter names without adding meaning to the nested 'communication' and 'email' objects, which are generic and lack further specification.

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?

Clearly states it creates and dispatches a company-level email communication. However, it does not differentiate from similarly named siblings like 'create_company_level_email' or 'create_email', which may cause confusion.

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?

Provides a warning about repeated calls causing resends and lists required parameters, but does not specify when to use this tool over alternatives or provide context for when not to use it.

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