Scored across 4 tools
Each tool targets a distinct resource: grammar patterns, words, kanji, and courses, with very detailed descriptions that clarify scope. Minor overlap exists where both find_grammar and lookup_word claim to answer 'how to say something,' but the resource distinction (pattern vs. word) is clear enough.
All names follow a verb_noun snake_case structure (find_grammar, lookup_kanji, lookup_word, list_courses). The only inconsistency is the mixed verb choice between 'find' and 'lookup' for essentially similar lookup operations, a minor deviation.
Four tools is a small but well-scoped set that covers the site's main content types without redundancy. Each tool clearly earns its place, though the surface is on the lean side.
The set covers the core learning resources: grammar, vocabulary, kanji, and courses/study material. Notable intentional gaps exist (no dedicated conjugation tool, no quiz/practice tool, no on'yomi/kun'yomi or stroke order), but these are explicitly scoped out and workable around.
Available Tools
4 toolsfind_grammarFind a Japanese grammar pointARead-onlyIdempotentInspect
Use this when the user asks about a Japanese grammar pattern or particle (〜てもいい, ために, ば vs たら, は and が), what it means, how it is used, an example of it, or how to say something with a pattern. Searches the site’s 828 grammar points (N5–N1) by the pattern in Japanese or romaji, or by its meaning in the user’s language. Each result has the pattern, JLPT level, meaning in the user’s language, an example sentence with translation, a recording of the example where available, and the grammar page; plus the site’s course lessons whose titles match, with links and whether each is free or needs a subscription or pass.
Inputs: query (required), lang, level, limit. Returns: lang, query, lessons, results
list_coursesJLPT levels and coursesARead-onlyIdempotentInspect
Use this when the user asks how to study Japanese or prepare for a JLPT level with Japanese Skills · 言の葉, or what study material the site has. Lists the study library (sections, counts and links), the JLPT practice levels (number of questions; links for the free ones), and the 15 courses with their level, number of lessons and link. With course, lists that course’s lessons with titles and links. Each level, course and lesson is labelled free or needs a subscription or pass.
Inputs: lang, course. Returns: jlpt, lang, course, courses, +3 more
lookup_kanjiWords that use a kanjiARead-onlyIdempotentInspect
Use this when the user asks about a kanji (a Chinese character used in Japanese): which JLPT words use it and how it is read in them, at which JLPT level it first appears, or where to learn it. For each kanji given (up to five), lists the words in the site’s JLPT word list that contain it, easiest level first, with reading, level and meaning in the user’s language; how many words use it and the lowest level among them; and the site’s kanji lessons that teach it (title, link, and whether each is free or needs a subscription or pass). Gives no on’yomi/kun’yomi table or stroke order: the readings are those of the words.
Inputs: kanji (required), lang, limit. Returns: lang, kanji, credit, results
lookup_wordLook up a Japanese wordARead-onlyIdempotentInspect
Use this when the user asks about a Japanese word: what it means, how to read or pronounce it, its pitch accent, whether it is a godan or ichidan verb, how to conjugate it (te-form, past, polite, potential…), or how to say something in Japanese. Searches the 9,040 JLPT words (N5–N1) of Japanese Skills · 言の葉 by the word in kanji or kana (食べる, たべる), romaji (taberu), or a meaning in English, Chinese or Korean (eat, 吃, 먹다). Each result has the reading, JLPT level, the meaning in the user’s language, the pitch accent (accent number, type and H/L pattern), the word class and conjugation table where the site has one, an example sentence with its translation where the site has one, recordings in two voices where available, and the word’s page. Shows a word card in chats that display app UI. Returns no results when the word is not in the list. Not for translating whole sentences.
Inputs: query (required), lang, level, limit. Returns: lang, site, query, credit, +1 more
