OpenHarness, developed by HKUDS, is an open-source, lightweight Python framework providing essential infrastructure for advanced AI Agents. Functioning as a comprehensive 'Agent Harness,' it equips large language models with robust tool-use capabilities (43+ tools), skill management, persistent memory, and sophisticated multi-agent coordination. Key features include parallel streaming agent loops, intelligent context compression, multi-level permission governance, and a flexible plugin ecosystem. OpenHarness empowers researchers and developers to deeply understand, experiment with, and extend production-grade AI Agents. Its capabilities are showcased by ohmo, an intelligent assistant for multi-day tasks like code generation and PR management across platforms such as Feishu and Slack, leveraging existing LLM subscriptions without extra API keys.
