OpenHarness

OpenHarness is agent infrastructure you pip install: the tool-calling loop, 43 built-in tools for files, shell, search, web, and MCP, plus skills, memory, permission modes, and multi-agent coordination. It also ships ohmo, a personal agent built on top of it that lives in Slack, Discord, Telegram, or Feishu and will fork a branch, write code, run tests, and open a PR on its own. MIT, Python 3.10 or newer, free.

The ohmo part is the interesting trick. It runs on a Claude Code or Codex subscription you already pay for rather than a separate API key, so a chat-driven coding agent costs nothing extra. Setup is pip install openharness-ai, then oh setup to pick a provider and ohmo gateway start to put it in your chat app. It reads CLAUDE.md, loads Anthropic-style skills and plugins, and compacts its own context.

Here is the problem. The last commit landed June 4, 2026, the last PyPI release was 0.1.9 on May 7, and there are dozens of open issues with nobody working them. This is a university research group's project that got popular fast, and popularity is not maintenance. For anything you depend on, langchain-ai/langgraph and crewAIInc/crewAI have real release cadences; for the coding agent job specifically, openclaw/openclaw is still shipping.

The catch is that a stalled repo and a permission system make a bad pair. ohmo runs shell commands and opens PRs on your behalf, which is exactly the code you want getting security fixes. Fine for a prototype on a throwaway repo. Not something to point at code you care about until commits resume.
