OpenHarness is a lightweight open-source agent harness in Python providing tool use, skills, memory, and multi-agent coordination, launched via a single 'oh' CLI command. It includes ohmo, a personal AI agent that chats over Feishu/Slack/Telegram/Discord and autonomously writes code, runs tests, and opens PRs using existing Claude Code or Codex subscriptions.

Use cases

  • build a personal AI coding agent that opens PRs autonomously
  • run an agent harness with tool use, skills, and memory
  • coordinate multiple AI agents from a single CLI
  • chat with an AI assistant via Telegram or Discord that works on my repo
  • reuse my Claude Code subscription without extra API keys
  • add long-session memory and skills to an LLM agent
  • integrate CLI agents like Cursor or nanobot into one harness

When to choose

  • you want an open, hackable agent harness with 43+ built-in tools
  • you need a personal agent reachable through chat platforms that can code and open PRs
  • you want multi-agent coordination and memory without building infrastructure yourself
  • you already pay for Claude Code or Codex and want to leverage it

When to avoid

  • you need a simple chatbot with no coding or repo access
  • you require a fully managed cloud agent service with no local setup
  • you need non-Python agent runtimes or guaranteed enterprise support
