Search Sri Guru Granth Sahib (SGGS) by concept or keyword. Query in plain English — e.g. 'get rid of ego', 'love for God', 'fear of death'. Searches the English translations and returns matching lines with Gurmukhi text, English transliteration, translation, author, and Ang (page) reference.

Fetch all lines on a given Ang (page number) of the SGGS. Ang range: 1–1430.

Fetch a specific line from the SGGS by its BaniDB verse ID (an integer, as returned by search_gurbani).

Given any line ID from the SGGS, return the complete Shabad (hymn) it belongs to — all lines in order, with Gurmukhi text, English transliteration, translation, and Ang reference. Use this after search_gurbani to expand a matching line into its full hymn context.

Check whether a Gurmukhi quote is authentically present in the source scripture. ALWAYS call this before presenting any Gurmukhi quote that did not come directly from another tool's result (e.g. a quote recalled from memory). Returns the verbatim source text + citation (Ang, author) if found, or NOT FOUND — in which case the quote must not be presented as authentic. Tolerates vishraam/punctuation/spelling differences; the returned text is always the source's own.

Audit a block of prose: find every Gurmukhi span in it and verify each against the source scripture. Use to check a drafted answer (or existing content) before presenting it. Returns each span's verdict (verified / not found) with citations.
