mail_listOrdersV1

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

No annotations are provided. The description adds that the list is paginated and includes fields like status, plan, domain, and expiration, which is useful. However, it does not disclose rate limits, side effects, or default pagination behavior beyond what the schema implies.

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 two sentences, efficiently stating the purpose and usage context without unnecessary words. Every sentence adds value.

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?

Without an output schema, the description mentions the included fields but does not specify the full response structure (e.g., total count, pagination metadata). For a paginated list tool, this is a notable gap, though the core functionality is clear.

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 100%, so the schema already documents all parameters. The description adds no additional meaning beyond the parameter names and types, providing no extra context for their use.

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 the verb 'Retrieve' and the resource 'paginated list of mail orders associated with your account.' It distinguishes from sibling mail tools like mail_getOrderPlanV1, which focuses on a single order plan.

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 explicitly says 'Use this endpoint to monitor your mail services,' providing a clear use case. However, it does not mention when not to use or compare to alternative list endpoints among siblings, though the context is sufficiently clear.

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