Delete Alias

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

The description is consistent with the destructiveHint annotation but adds no extra behavioral context such as permanence, side effects on mail delivery, or whether confirmation is required. The annotation already flags destructive intent, so the minimal disclosure is acceptable but not enriched.

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 sentence with no filler or repetition. It is optimally concise and front-loaded with the action.

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?

For a simple delete tool with one well-documented parameter and a destructive annotation, the description is reasonably complete. It lacks output/effect details, but the low complexity and existing schema/annotation cover most needs.

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% for the single parameter alias_id, and the description adds no additional meaning beyond 'Alias ID' already in the schema. Baseline score is appropriate.

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 uses a specific verb 'Delete' and a clear resource 'email alias', unambiguously distinguishing this tool from sibling tools like mail_aliases_list and mail_aliases_create.

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 provided on when to use this tool, how to obtain the required alias_id, or any conditions/preconditions. The description merely states the action without context or alternatives.

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