excerpt_prepare

Generate (or fetch, if cached) the audio clip for a lecture passage and return its playable URL. This is the excerpt player's Play action — it is called for you by the player UI on demand. Agents should use excerpt_render to show the player, not call this directly. Idempotent: same track+window returns the same cached clip.

Parameters3

end_ms	number	required	Passage end (ms), > start_ms; span <= 600000.
start_ms	number	required	Passage start (ms).
track_id	string	required	track_id.

excerpt_render

Let the user HEAR a lecture passage inline. Call this when the user wants to LISTEN to a specific moment in a track — e.g. from a search(types:["track"]) hit, pass its track_id plus start_ms/end_ms. Renders an inline audio player that generates the clip on demand (public share-audio, max 10 minutes).

Parameters4

end_ms	number	required	Passage end (ms), > start_ms; span <= 600000 (10 min).
lang	string	optional	Transcript language (ISO-639-1).
start_ms	number	required	Passage start (ms).

search

Semantic + lexical search over the corpus.

date_from	string	optional	Track date lower bound YYYY-MM-DD.
date_to	string	optional	Track date upper bound YYYY-MM-DD.

types	array	optional	Subset of verse\|document\|track\|title\|media (default all). A `media` hit is a short video clip playable via media_render.

verse_get

Fetch a verse's raw fields for your own reasoning (NOT for display — to show a verse to the user, use verse_render). Returns original script + transliteration as line arrays; with lang, also the canonical translation inline plus an `alternatives` manifest of other translation kinds in that language (fetch their text with verse_translation, word-by-word with verse_synonyms). Address by ref ("BG 2.13"), source+tokens, or verse id.

Parameters5

id	string	optional	verse_id.
lang	string	optional	Answer language. Set it to get the canonical translation + alternatives manifest.
ref	string	optional	Reference string, e.g. "BG 2.13".
source	string	optional	Book code / source_id (with tokens).

lang	string	optional	Preview language.
limit	number	optional	Max items (default 100, max 500).

}

verse_render

Show a verse to the user. THE DEFAULT way to display/read a scripture verse: renders an inline card with the original script (centered), transliteration in the requested language, the word-by-word, and the translation — all at once. Use this whenever the user asks to see, read, open, or quote a specific verse ("покажи БГ 2.13", "read Bhagavad-gita 2.13"). The other verse_* tools are for fetching raw data; for DISPLAY prefer this one. Address by ref ("BG 2.13"), source+tokens, or id; lang sets the script + translation language.

Parameters6

id	string	optional	verse_id.
kind	string	optional	Translation kind; default "canonical".
lang	string	required	Display language, e.g. "en", "ru".
ref	string	optional	Reference string, e.g. "BG 2.13".
source	string	optional	Book code / source_id (with tokens).

verse_synonyms

Fetch the word-by-word ("Synonyms") as a raw {word, meaning} array for one verse translation (data — verse_render already shows the word-by-word inside the card). Defaults to the canonical rendering; pass `kind` for an alternative.
