TDQS

A3.9/5.0

Scored across 2 tools

Disambiguation5/5

get_recall_detail retrieves a single record by management number, while search_recalls queries by keyword and category. Their purposes are clearly distinct with no overlap or ambiguity.

Naming Consistency5/5

Both tools follow a consistent snake_case verb_noun pattern: get_recall_detail and search_recalls. The slight singular/plural difference is natural for the operations and does not break predictability.

Tool Count4/5

Two tools cover the core search and detail operations for a read-only recall lookup service. While slightly below the typical 3–15 range, each tool is well-scoped and earns its place for this narrow domain.

Completeness4/5

Search and detail provide complete coverage for retrieving recall information, including pagination and filtering. A minor gap is the absence of a tool to list available categories or metadata, which could help agents construct searches without guessing category codes.

B3.3/5.0
Behavior2/5

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 does not state that this is a read-only operation, whether the lookup can fail for a nonexistent/invalid number, or anything about the returned record's shape. The verb 取得 weakly implies a read, but that is the extent of the disclosure.

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?

Two short sentences, purpose front-loaded, example tucked at the end. Nothing wastes space.

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

Completeness3/5

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

For a one-parameter lookup with a fully documented schema this is roughly sufficient, but with no annotations and no output schema the description could reasonably say what the returned detail contains and that the call is non-mutating. Those gaps keep it at minimum-viable.

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% and the single parameter is already documented as an 11-digit management number with an example in the schema. The description repeats the digit count and adds an input example, which is marginal value over the structured field.

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

Purpose4/5

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

States a specific verb and resource: retrieves one recall detail keyed by an 11-digit management number. The singular '1件' (one record) implicitly contrasts with the sibling search_recalls, though it never names that sibling explicitly.

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

Usage Guidelines3/5

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

Usage is implied rather than stated: an agent can infer it should call this when it already holds a management number and wants the full record. There is no explicit guidance on when to prefer search_recalls instead, nor any note on what happens with an unknown number.

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

search_recallsAInspect

消費者庁リコール情報サイトをキーワード+カテゴリで検索します。検索語は日本語推奨(英語の代表語は日本語に読み替えます。例: stroller→ベビーカー)。かな/全角/英語を読み替えて検索した場合は summary に「〜として検索しました」と明記します。JAN・型番の照会は keyword にそのまま渡せます。入力例: {"keyword": "サーキュレーター", "category": "0", "limit": 15}掲載日の絞り込み posted_since/posted_until(YYYY-MM-DD・両端含む)を指定すると、上流の新しい順に最大5ページ(75件)まで走査して絞り込みます。total_count・range・nextCursor はいずれも limit 単位の論理位置(絞り込みありは絞り込み後、なしは上流順の続き)を示します。上限で打ち切った場合は summary に「上流の先頭75件までを確認」と明記します。

A4.2/5.0
Behavior5/5

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

With no annotations, the description carries the full burden and delivers: it discloses transliteration feedback in summary ('〜として検索しました'), the 75-item upstream scan cap and its truncation notice, and the logical position semantics of total_count/range/nextCursor under filtering. This is unusually rich behavioral disclosure for a search tool.

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

Conciseness4/5

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

Front-loads the purpose, then usage rules, an example, and pagination semantics. Dense but every clause carries operational information; minor overlap with the schema's date-inclusivity wording.

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?

No output schema and no annotations, so the description must cover behavior — and it explains pagination, truncation, and summary-signaling well. Missing only auth/rate-limit context, which is minor for a public read-only search endpoint.

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

Parameters4/5

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

Schema coverage is 100%, so baseline is 3, but the description adds real meaning beyond the schema: keyword accepts JAN/model numbers verbatim, transliteration is applied, and it clarifies what total_count/range/nextCursor represent relative to limit. Adds value on top of documented params.

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

Purpose4/5

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

States a specific verb and resource: searches the Consumer Affairs Agency recall site by keyword+category. The sibling get_recall_detail is not named, but the search-vs-detail distinction is unambiguous. Strong but lacks explicit sibling routing.

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?

Gives clear context: Japanese keywords recommended, english terms auto-transliterated, JAN/model numbers can be passed directly to keyword, and a concrete input example. It also bounds date filtering to 75 items / 5 upstream pages. No explicit when-not or sibling alternative, so not a 5.

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