  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

fetch

Fetches the full live Lingard JSON record for a search-result id (e.g. "learning-context:en") or a Lingard resource URI such as lingard://learning-context/en.

Discovered
lingard_add_words_to_collection

Adds cards to an existing Lingard collection, deduplicating by normalized word title; commit=true writes them. Only collections with writable="full" accept new cards: curated Lingard collections are read-only and the unfiled bucket takes no new cards. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms. It only adds: a word already in the collection gets its empty fields filled (mergeMode "fill_missing", the default) or is left alone ("add_only"); a value that is already filled in is never changed or cleared.

Discovered
lingard_attach_card_images

Attaches supplied images to existing Lingard cards. It does not generate images: each entry carries the image itself as imageBase64 or dataUri, or an imageUrl that the server downloads. PNG, JPEG, WebP, and SVG inputs are converted to WebP and uploaded as private custom card images; an image the card already has is replaced. commit=true writes.

Discovered
lingard_commit_vocab_changes

Commits a previously previewed or freshly supplied Lingard vocabulary change. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms. This is the tool that corrects existing cards: mergeMode:"overwrite_non_empty" replaces values that are already filled in and clearFields:["form"] clears a wrong grammatical form, which is why it is marked destructive.

Discovered
lingard_create_vocab_collection

Creates a Lingard vocabulary collection, optionally with initial cards; commit=true writes it. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms.

Discovered
lingard_fill_missing_card_fields

Fills empty fields on existing Lingard cards. It never overwrites or clears a field that already has a value. Works on the user's own collections and on the "Words not in a collection" bucket; curated Lingard collections are read-only because their content comes from the Lingard catalog. commit=true writes.

Discovered
lingard_get_collection_gaps

Returns live Lingard cards in a collection that are missing requested fields such as translation, POS, pronunciation, examples, or image. A curated Lingard collection always reports zero gaps: its words come from the Lingard catalog and are not the user's to fill.

Discovered
lingard_get_learning_context

Returns the user's current Lingard learning context, read live from their account: English profile, vocabulary totals, saved collections and their titles, card counts, and missing-field stats. Earlier answers in the conversation may be out of date; this is the account as it stands now. The list covers every collection the account has, so the per-collection counts add up to the card total (totals.truncated marks a library too large to list in full). Every collection reports `source`: "user" (made by the user), "catalog" (a curated Lingard collection — read-only, its words come from the Lingard catalog) and "unfiled" (the bucket of cards saved while reading, which belong to no collection). Catalog and unfiled entries carry titles the user did not choose; they belong to the same account all the same.

Discovered
lingard_get_learning_pauses

Lists, for one language, the user's collections and sources (books, the news) and which of them are on pause. A collection or source on pause gives the automatic «Now learning» sessions no words — no new words and no reviews — and is not counted in the day's goals or reminders; opening it in the app still studies it as usual. Each entry carries the exact uuid, bookKey, and title that pause changes take.

Discovered
lingard_get_vocab_collection

Returns live cards from one Lingard vocabulary collection by UUID or title, including curated Lingard collections and the "Words not in a collection" bucket of cards saved while reading. With includeExamples:true it also returns each card's example sentences and their translations, which editing examples starts from.

Discovered
lingard_get_word_suggestion_context

Returns live Lingard profile level, topic, collection context, and the words the user already has: the context for suggesting level-appropriate new cards that are not duplicates.

Discovered
lingard_preview_vocab_changes

Previews a Lingard vocabulary collection/card change without writing to Firestore. Cards are checked as on commit. Unless allowIncompleteCards is true, a new card needs title, translate, pos, pron/ipa, syns, and examples with translations; image is optional. A German or Romance noun title carries its dictionary article when one is used, e.g. der Hund, die Reise, das Haus. In example text and example translation the target word and the translated word are marked with {}. form is not part of speech: it holds the inflected-form category of the current word and stays empty for base forms.

Discovered
lingard_set_learning_pauses

Puts collections and sources on pause or takes them off it, for one language — e.g. "study only my Travel collection this week", "pause the news words", "resume everything". action: "pause" or "resume" the listed ones; "only" — resume the listed ones and pause every other collection and source of the language; "resume_all" — take every pause off (lists ignored). Collections are named by uuid or exact title and sources by bookKey or exact title, as the learning-pause list reports them. A paused item gives the automatic «Now learning» sessions no words and is not counted in goals or reminders; opening it in the app still studies it. commit=true writes; without it the call returns a preview of the changes and the resulting state.

Discovered
lingard_update_example_translations

Rewrites only the translation line of examples that already exist on Lingard cards; the example sentence, its {} highlights and its audio/typing markers are left exactly as they are. It changes, adds, or removes example translations; an empty translation is a supported card state, not an error. `translations` holds one entry per existing example, in order, so it is built from the card's current examples (a collection read with includeExamples:true lists them). commit=true writes; without it the call returns the resulting examples as a preview.

Discovered
search

Searches the user's live Lingard account: vocabulary, learning context, English profile, totals, collection titles, saved words, flashcards, and missing vocabulary fields. Results are read from Firestore at the time of the call.
