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

No annotations are provided, so the description carries the full burden, yet it discloses nothing about permission requirements, whether the unmapping is reversible, whether the domain's DNS/registration is affected, or the response behavior. 'Unmap' hints at a state-changing operation, but no behavioral detail follows.

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 single sentence is front-loaded and wastes no words. The brevity is under-specification rather than efficient density, but structurally it is clean.

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 two-required-parameter mutation with no annotations and no output schema, the description is far too thin. An agent lacks the behavioral and parameter context needed to invoke this confidently.

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 50%: 'project' has a description ('Project name') while 'host' is bare, and the description adds no meaning for either. It does not clarify that host is the domain to be unmapped from the given project, leaving the parameter gap unfilled.

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 pairs a verb ('Unmap') with a resource ('domain'), which distinguishes it from siblings like domains.buy, domains.connect, and domains.verify. However, 'unmap' is jargon that never states what is actually unlinked (a host from a project) or what state changes, so the purpose is only vaguely conveyed.

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?

There is no guidance on when to use this versus domains.connect, domains.verify, or project.delete, and no prerequisites or exclusions are given. The agent must infer usage entirely from the tool name.

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