email_pop_delete

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It only says 'Delete a mailbox' and lists arguments; it does not disclose that deletion is permanent, that confirm is required for the deletion to proceed, or any side effects or permission requirements. The 'confirm: Required' note is present but terse and conflicts with the schema's default, leaving behavioral expectations unclear.

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 concise, with a clear one-line purpose followed by a compact argument list. There is no filler, and the purpose is front-loaded. It loses a point for the terse argument list omitting useful structural detail, but overall it is efficient.

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 destructive operation with no annotations, this description is incomplete. It does not explain what happens when a mailbox is deleted, whether confirm must be set to true, what the output contains, or how this tool relates to other email deletion tools. The existence of an output schema does not cover these gaps because the description fails to give usage context.

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 0%, so the description must compensate. It does list all four parameters with brief glosses ('Domain', 'Local part', 'Owning user', 'Required'), which adds some meaning beyond bare titles. However, 'confirm: Required' is misleading because the schema shows confirm as optional with default false, and no value or format guidance is given for any parameter.

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 specific verb and resource: 'Delete a mailbox.' This clearly indicates a delete operation and, combined with the tool name email_pop_delete, distinguishes it from email_pop_list/create/modify siblings. However, it does not explicitly say 'POP account' or explain what 'mailbox' means, so it lacks explicit sibling differentiation in the text.

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 versus alternatives. There is no mention of prerequisites, context, or when a different delete tool (e.g., email_forwarders_delete) would be appropriate. The description only states the action with no usage direction.

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