revoke_domain_transfer_out

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

The annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is known. The description adds nothing beyond the annotations — it doesn't say what state is destroyed or restored, whether the transfer lock is re-enabled, whether the domain must be in a specific transfer state, or whether the action is reversible.

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 repeats itself verbatim: the same sentence appears once as the summary and again after the endpoint bracket, with nothing new added. The endpoint path, which is the only extra information, is buried mid-string.

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?

This is a destructive mutation with no output schema and no annotation explaining preconditions or side effects; the description should at minimum state that the transfer-out request is voided and what the domain's resulting state is. Neither is covered, leaving an agent unable to predict the effect of the call.

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 100%, so both the 'domain' and 'x-trace-id' parameters are already documented in the schema, and the description adds no additional semantics. Baseline 3 applies when the schema does the heavy lifting.

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?

States a specific verb and resource ('Revoke transfer out for a domain') plus the HTTP endpoint, so the action is unambiguous. However, it does nothing to distinguish it from closely related siblings such as confirm_domain_transfer_out, revoke_cancel_domain, or cancel_domain.

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 when-to-use or when-not-to-use guidance is given, and no alternatives are named. With siblings like confirm_domain_transfer_out and revoke_cancel_domain in the same domain-name namespace, the agent is left to infer which operation applies to which state.

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