Description

Hi HN,I built OpenHarness , an open-source terminal coding agent that works with any LLM: Ollama (free, local), OpenAI, Anthropic, Deepseek, Qwen or any OpenAI-compatible API. Install and run: npm install -g @zhijiewang/openharness oh # auto-detect local model oh --model ollama/qwen2.5:7b # specific model What it does: - 17 tools (file read/edit/write, bash, grep, glob, web search, task management, notebooks) - 16 slash commands (/diff, /undo, /commit, /cost, /compact, /plan, /review...) - Git integration: every AI edit auto-committed, /undo reverts instantly - Headless mode for CI/CD: oh run "fix the tests" --json - Permission gates: ask/trust/deny modes so the agent can't rm -rf without approval - React+Ink terminal UI with markdown rendering and shimmer spinner Demo: https://github.com/zhijiewong/openharnessSource: https://github.com/zhijiewong/openharnessnpm: npm install -g @zhijiewang/openharnessopenharness is ready to collborateEveryone is welcome to join and build it together.
