mailu_create_relay

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

No annotations are provided, so the description bears full responsibility. It only indicates a write operation ('create') but fails to disclose any behavioral traits such as destructive potential, required permissions, rate limits, or side effects. The minimal description leaves the agent uninformed about operational risks.

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?

A single, efficient sentence delivers the core purpose. It is not verbose and front-loads the action. However, it could incorporate more essential details (e.g., required parameters) without losing conciseness.

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 lack of output schema and annotations, the description should provide more contextual completeness. It does not explain return values, success/failure indicators, or post-conditions. For a creation tool, this omission hinders an agent from understanding what to expect after 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?

Schema description coverage is 67% (2 of 3 parameters described). The description adds no additional semantic value beyond the parameter names and existing descriptions. For example, it does not clarify expected formats for 'smtp' or the purpose of 'comment'. Baseline scenario applies.

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 tool creates a relay (domain relayed to a target SMTP). The verb 'create' and resource 'relay' are explicit. However, it does not differentiate from any siblings (none provided) and the term 'relay' could be more precisely defined for email routing context.

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 given on when to use this tool or when to avoid it. There is no mention of prerequisites, alternatives, or context. The description solely states what it does without any usage direction.

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