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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful behavioral context by revealing that the tool computes Daitch–Mokotoff Soundex codes, pre-1918 orthography, male/female surname forms, and transliterations. However, it does not discuss limitations, determinism, or whether results are exhaustive.

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 is a single front-loaded sentence with a colon-delimited list of examples. Every element earns its place by concretely expanding the scope of name forms. It is dense but not padded, though the long parenthetical list could be structured more scannably.

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?

An output schema exists, so the description need not explain return values, and annotations cover the read-only nature. The description adequately conveys the generated content. However, it leaves clear gaps in parameter semantics and usage guidance for a tool with a non-obvious 'kind' parameter and many research-oriented siblings.

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?

With only 50% schema description coverage, the description needs to compensate, but it does not explain the 'name' parameter's expected format or how the 'kind' enum (surname, given, patronymic) changes the output. It gives examples of surname and given-name forms, but these are illustrative of output content rather than parameter semantics. The schema description for 'kind' is just 'What the name is', which the description does not clarify.

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 states the resource — all forms a name can take in records, including Soundex codes, spelling variants, orthography, transliterations, and cross-language equivalents. It is not a tautology and gives concrete examples that make the tool's scope unmistakable. It stops short of a full 5 because it does not explicitly differentiate this tool from any sibling by name.

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 says what content the tool provides, but it never states when to use it, when not to use it, or which sibling tool to use instead. There is no guidance about prerequisites, appropriate contexts, or alternatives. An agent can infer some usage from the content list, but that is not explicit guidance.

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