Summary

The University of Hong Kong Data Intelligence Lab has open-sourced the lightweight agent framework OpenHarness and its built-in agent Ohmo, providing core features like tool calling, memory, multi-agent coordination, and support for platforms like Feishu and Slack.

A lab at HKU has open-sourced an agent skeleton, complete with a built-in agent called Ohmo that's ready to work right out of the box. It already has 14.3k stars on GitHub, from the University of Hong Kong Data Intelligence Lab (HKUDS) — the same team that built LightRAG. That's a solid endorsement. Building a usable agent from scratch, just piecing together the foundation like memory, tool calling, and multi-step task scheduling, can take a whole week. OpenHarness gives you this skeleton pre-assembled. If you want an agent that can read files, connect to the internet, and remember your preferences, just install it and go — no need to reinvent the wheel. If you're serious about studying how agents actually work but don't want to be overwhelmed by complex frameworks, this is a great starting point. If you want to understand the internals of agents, reading its code is far more valuable than reading ten blog posts. GitHub:
