Saksham is HexaHealth's production multi-agent RAG platform. It pairs Mastra AI agents with Gemini 2.5 Flash, a Pinecone vector store (768-dim, 5+ namespaces) over 10K+ indexed healthcare documents, and a real-time bidirectional voice channel over WebSocket using Gemini Live. Persistent conversational memory is backed by PostgreSQL with observational layers and 7 LLM-callable tools (symptom checker, semantic search, appointment booking). Every turn is traced with Langfuse + OpenTelemetry; access is hardened with prompt-injection detection, one-time session tokens, and IP-based rate limiting.
