jp_lit_search

Search Japanese literature databases across NDL, CiNii, J-STAGE, and more. Cross-search eight sources or specify a single source for targeted results.

Instructions

external read / local bookkeeping write(非破壊)。日本語文献ポータルを検索する。source 未指定で8ソース横断。cinii_dissertations / national_archives / jacar / nijl_articles / kokusho / ninjal_bibliography は既定横断に含めず、博士論文・学位論文、公文書・外交・軍事・旧外地資料、国文学論文、古典籍、日本語研究文献などで明示指定された場合のみ使う。ユーザーの言い回しから source を読み替える: 「NDL/国会図書館」→ndl_catalog、「デジコレ/NDLデジタル」→ndl_digital、「CiNii論文」→cinii_articles、「博士論文/学位論文/CiNii Dissertations」→cinii_dissertations、「CiNii図書/大学図書館」→cinii_books、「J-STAGE」→jstage_articles、「機関リポジトリ/IRDB」→irdb、「国会会議録」→kokkai_minutes、「帝国議会」→teikoku_minutes、「人文専門DB/nihu_bridge」→nihu_bridge、「Japan Search/ジャパンサーチ」→japan_search、「国立公文書館/特定歴史公文書/太政官/省庁資料」→national_archives、「JACAR/アジア歴史資料/外交/軍事/旧外地/植民地/朝鮮/台湾/関東州」→jacar、「国文学論文/国文研論文/日本文学研究論文」→nijl_articles、「国書/古典籍/写本/版本」→kokusho、「日本語研究/日本語教育文献/国語教育文献」→ninjal_bibliography。total / limit / page はこの 1 回の検索呼び出し単位の値であり、Skill が複数回検索して要約する場合は各回ごとに読む。source=cinii_books では filters.cinii.category に NDC/NDLC notation を半角スペース区切りで渡せる。CiNii 系の 0 件・ローマ字 query・広すぎる結果では interpretation / diagnostics を読む。source=ndl_digital の結果にはインターネット非公開(館内限定・図書館送信)資料のメタデータも含まれる。OCR 系ツールを使う前に jp_lit_get_record で source_metadata.next_digital_library.available を確認すること 外部sourceは変更しない。cache hitでもlocal session履歴を更新し、cache missまたはforce_refreshではlocal cacheを作成・置換する。

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
pageNo検索結果ページ番号。1 始まり。
limitNo1 回の検索で返す最大件数。最大 100。未指定時は source ごとの既定値を使う。
queryYes検索語。資料名、著者名、主題語、機関名などを指定する。
sourceNo検索対象 source。未指定なら既定の 8 source 横断検索になるが、新規テーマの初手では通常 ndl_search と japan_search などを明示指定する。
filtersNosource 固有の追加 filter。対象 source と一致しない filter は validation error になる。
sort_byNosource が対応する場合の並び替え項目。未対応 source では無視されることがある。
issued_toNo刊行年・日付の上限。issued_from と組み合わせて範囲指定する。
sort_orderNosort_by 指定時の昇順 asc / 降順 desc。
issued_fromNo刊行年・日付の下限。年だけの '1900' など source が扱う文字列表現で指定する。
force_refreshNotrue の場合はローカル cache を使わず upstream API から再取得する。false の場合は保存済み cache を優先する。

Behavior5/5

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

Discloses non-destructive local writes, cache behavior, and that external sources are not modified. Notes that ndl_digital results include non-public metadata. Annotations are consistent with description, no contradictions.

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?

Description is lengthy but well-organized with logical sections (purpose, source rules, mapping, semantics, special notes). Every sentence adds value; slightly dense but appropriate for complexity.

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

Completeness5/5

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

Covers all essential aspects: purpose, source selection, behavior, ties to other tools, and interpretation of results. With output schema present, return values are covered externally. Comprehensive for a complex tool.

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 already provides detailed parameter descriptions (100% coverage). Description adds significant value beyond schema: clarifies source mapping, per-call semantics, and special filter usage (e.g., NDC/NDLC for cinii_books).

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?

Description clearly states the tool searches Japanese literature portals, specifies cross-search of 8 default sources, and lists 20 specific sources with mapping from user phrasing. It distinguishes itself from sibling tools by detailing source behavior and inclusion rules.

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

Usage Guidelines5/5

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

Provides extensive usage guidelines: when to use specific sources, mapping of user terms, when not to use certain sources, how to interpret CiNii results, and recommends using jp_lit_get_record before OCR. Includes per-call semantics for total/limit/page.

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