 ## Overview
 
-`@framers/agentos` is an open-source TypeScript AI agent runtime for building, deploying, and managing production AI agents. It provides multimodal RAG with cognitive memory (Ebbinghaus decay, 8 neuroscience-backed mechanisms including reconsolidation, retrieval-induced forgetting, involuntary recall, metacognitive FOK, temporal gist extraction, schema encoding, source confidence decay, and emotion regulation — all HEXACO personality-modulated), multi-agent orchestration, 37 channel adapters, 5-tier guardrails with prompt injection defense, 21 LLM providers, and 72 curated skills. Self-hostable and production-ready, it handles the full lifecycle from prompt construction through tool execution, safety evaluation, and streaming response delivery.
