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

With no annotations, the description carries the full burden. It discloses that results are sorted reference pricing, which is genuinely useful behavioral context, but says nothing about price freshness, data source, whether values are cached/approximate, or read-only safety. Reasonable but incomplete for an unannotated tool.

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?

A single front-loaded sentence leading with the verb and the two use modes. Efficient with no filler, though the visible text trails off mid-clause ('budget domain…'), leaving the structure slightly incomplete.

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-optional-param tool with no annotations and no output schema, the description covers purpose, both modes, and the return shape at a high level. It omits what the default behavior is when no parameter is given and any caveat about price accuracy, which are the remaining gaps.

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%, so the description must compensate for the two undocumented params. It indirectly maps the two modes (TLD vs. name) to the inputs, which is helpful, but never names 'tld' or 'name', does not state they are optional, and does not say what happens if both or neither is supplied.

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 (compare) and resource (registration/renewal/transfer prices) with two clearly named modes: a TLD across registrars, or a name across TLDs. This distinguishes it well from sibling tools like domain_availability, domain_appraise, and whois_lookup. It stops short of naming a sibling directly, but the resource and scope are unambiguous.

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?

The description explicitly frames the two scenarios that select the tool — comparing registrars for one TLD vs. comparing TLDs for one name — and gives the goal (find the cheapest place to register, budget). It supplies clear context but no exclusions or named alternatives, which is the boundary for a 4.

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