domain_buy

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

No annotations provided, so description carries full burden. Discloses registration through Cloudflare and that DNS can be managed immediately, but does not cover error handling for insufficient balance, domain availability, or any restrictions (e.g., TLD limits).

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?

Two sentences with clear purpose upfront. While concise, it could benefit from structuring prerequisites and post-purchase details more explicitly.

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?

Output schema exists (not shown) so return values may be documented there. However, description omits critical context: need to check domain availability, what happens if domain is taken, or any cost implications.

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 0%, and the description adds no detail beyond parameter names. 'domain' and 'years' are mentioned implicitly but not explained (e.g., format, constraints like max years).

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 explicitly states 'Register/buy a domain' which clearly identifies the action and resource. It distinguishes from sibling tools like domain_check, domain_search, and domain_transfer.

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?

Mentions 'Requires sufficient wallet balance' as a prerequisite, but does not advise checking domain availability first or list alternatives. Implicitly, it is for purchasing domains, but lacks explicit when-to-use vs. when-not-to-use guidance.

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