A lightweight open-source Python implementation of the Agent Harness architecture. 44x lighter than Claude Code (11K vs 512K lines), 98% core tool coverage. - 43 tools with Pydantic validation and parallel execution - Skills system compatible with anthropics/skills (17+ tested) - Plugin system compatible with claude-code/plugins (12+ tested) - API retry with exponential backoff - Multi-level permissions with path rules - React/Ink TUI with "Oh my Harness!" branding - 114 unit tests + 6 E2E test suites - MIT License
