# LongHorizon-Harness

### Loop Engineering for Computer-Use Agents

**Give Claude Code, Codex, OpenCode, or DeepSeek Harness a goal once. Keep it working across desktop apps and the terminal for dozens of hours.**

**Plan → act → verify → checkpoint or recover → repeat — until the work is actually done.**
