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

No annotations are provided, so the description carries the full burden. It discloses the categories of information returned, which is useful, but it does not mention behavior for unregistered names, whether the operation is read-only, or any data-source caveats. The picture is clear but partial.

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 entire description is one information-dense sentence with a colon-delimited list of fields. There is no filler, and the core purpose is front-loaded. Every word earns its place.

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 simple one-parameter tool with no output schema, the description does state the primary output dimensions, which is helpful. However, it leaves out parameter-format details and gives no explicit guidance for choosing among sibling tools. Reasonably complete but with noticeable 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 description coverage is 0%, so the description must compensate. It does identify the single 'name' parameter as a '.hood name', but it gives no format detail such as whether the suffix should be included, case sensitivity, or how invalid names are handled. Basic meaning is present, but not full semantics.

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 clearly identifies the resource (.hood name) and scope ('full snapshot'), listing the key output areas: resolved address, NFT owner, expiry, and availability. The word 'full' helps differentiate it from the more targeted sibling tools. It lacks an explicit verb like 'Gets' or 'Returns', so it stops just short of a top score.

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?

Usage context is only implied. A 'full snapshot' suggests this is the comprehensive option compared to check_availability or resolve_name, but no explicit when-to-use, exclusions, or alternatives are named. An agent has to infer that this is the right tool when multiple pieces of name state are needed.

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