delete_domain

Destructive

Deletes a custom domain by its UUID and disables its aliases, so they stop working. Use it to remove domains you no longer want to route mail through.

Instructions

Delete a custom domain. Its aliases stop working.

A3.8/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true and openWorldHint=true, so the safety profile is known. The description adds value by disclosing a cascading effect not captured in annotations: existing aliases stop working after deletion. It still does not state whether the deletion is irreversible or requires confirmation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with zero filler; the purpose comes first and the consequence follows immediately. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter destructive tool with no output schema and annotations covering the safety hints, the description supplies purpose plus the main downstream side effect. Only irreversibility/confirmation behavior is left unstated, which is a minor gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With a single required parameter and 100% schema description coverage, the schema already documents domain_id as a UUID. The description adds no clarification about whether the identifier is an id or a domain name, so it does not exceed the baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Delete a custom domain') that clearly distinguishes it from sibling delete operations like delete_alias or delete_label, which target different entities. It does not, however, explicitly contrast itself with those siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the destructive nature of the operation and the note that aliases will stop working, which hints at the consequences of choosing this tool. There is no explicit statement of when to use this versus update_domain or delete_alias, and no prerequisites or confirmation guidance.

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