Criterion

balajsaleem/criterion

Connects Claude to a semantic search engine over 6,236 Quran verses and 21,641 authenticated Hadiths from six major collections. Exposes three tools: search_quran for natural language verse queries, search_hadith with grade and collection filtering (Sahih, Hasan, Da'if across Bukhari, Muslim, Tirmidhi, Abu Dawud, Nawawi, and Riyad as-Salihin), and get_verse for direct reference lookups like "2:255". Results include surrounding context (±2 verses) and cite sources with Quran.com and Sunnah.com links. Built on 768-dimensional Gemini embeddings with sub-200ms HNSW vector search. Reach for this when you need grounded Islamic textual references without hallucination, whether for research, religious education, or building applications that require authenticated scriptural citations.
