TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds valuable behavioral context by stating that the result contains only list and basic information, not actual statistical values ('実際の統計数値は含まれない'), clarifying what the user can expect beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences: the first defines the core action, the second clarifies what is excluded and how to proceed for actual data. Every sentence earns its place, with no redundant information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the high parameter count (12), rich schema descriptions, output schema presence, and annotations, the description is complete enough. It adds the crucial note about using an external tool for actual data, which is essential for the overall workflow.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% for all 12 parameters, including formats, enums, defaults, and semantics. The tool description does not add parameter-level detail beyond mentioning the output includes stats table ID, name, survey year, etc., so it neither improves nor degrades beyond the schema baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states '指定した条件に基づき、e-Statに登録されている統計表の一覧および基本情報（統計表ID、統計名、調査年月、公開日など）を取得する', which clearly identifies the verb (取得する), the resource (統計表の一覧), and the scope. It also explicitly says actual statistical values are not included, distinguishing it from data-retrieval tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance: 'ここで得た統計表IDを e-stat-get-stats-data ツールに渡して取得する', telling users to use the returned IDs with a specific complementary tool for actual data. It lacks comparisons with sibling tools e-stat-get-data-catalog and e-stat-get-meta-info, but the workflow guidance is clear.

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

A3.9/5.0
Disambiguation5/5

Each tool targets a distinct aspect: catalog metadata, statistical table metadata, and table listing. Their descriptions clarify the workflow (catalog -> list -> meta), so there is no ambiguity about which tool to use.

Naming Consistency5/5

All tool names follow the consistent pattern e-stat-get-<resource>, using snake_case and a clear verb-noun structure. This makes the set predictable and easy to navigate.

Tool Count3/5

With only 3 tools, the server is on the smaller side but not necessarily too few for a focused purpose. However, the descriptions refer to a missing e-stat-get-stats-data tool, suggesting the count is incomplete for the intended workflow.

Completeness1/5

The server lacks a tool to actually retrieve statistical data (e-stat-get-stats-data), which is explicitly referenced in two existing tools. This is a severe gap that prevents the server from fulfilling its core purpose.
