Ori Harness is a CLI wrapper that lets developers run popular AI agent tools — including Claude Code, Codex, Hermes, OpenCode, and Pi — through OpenRouter without managing API keys. It uses OAuth sign-in to connect to an existing OpenRouter account, applying org-level guardrails such as model allowlists and spending caps across every agent. Users can swap models on any agent with a single flag, and all usage and costs are consolidated into one OpenRouter bill. The tool requires no workflow changes, sitting transparently beneath existing agent commands and configurations.
