order_domain

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

Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true, so the safety profile is partly covered. However, the description adds nothing about the consequences of a non-idempotent, real-world purchase operation — no note that repeated calls can create duplicate orders, that transfers require an authCode, or that this is a committing/billable action.

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 repeated twice, including an endpoint path, so half the text is pure duplication. It is short but not efficient — no front-loaded detail about the two distinct modes (create vs transfer).

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 non-idempotent, open-world mutation with a deeply nested required body and no output schema, the description should say what the call commits to and how create and transfer differ (e.g. authCode usage). It supplies none of that, leaving the agent to infer behavior from the schema alone.

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% and nested fields (handles, nameservers, authCode, resourceId/resourceType) are individually documented, so the schema does the work. The description adds no semantics beyond it, which lands at the baseline 3.

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 names a concrete verb pair and resource ("Create or transfer a domain"), so the basic action is clear. But it is a verbatim restatement of the annotation title and offers nothing to distinguish it from siblings like list_domains, update_domain, suggest_domains, or validate_domain_availability.

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 validate_domain_availability (pre-check), suggest_domains, or update_domain, and no mention of when the 'transfer' path applies. The agent must infer the entire decision 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.
