Lionclaw is an open-source local control plane and orchestration harness developed in Rust by moshthepitt. It is designed to manage, sandbox, and standardize how existing CLI coding agents (such as Codex, OpenCode, and other agent harnesses) operate against local codebases. In daily developer workflows, Lionclaw sits between the user, the project environment, and the underlying AI agent CLI. Rather than replacing agent CLIs, it wraps them to manage project identity, local state persistence, session durability, containerized execution, communication channels, and scheduled background tasks. Lionclaw differentiates itself by focusing on governance, auditability, and boundary enforcement around coding agents. Instead of tethering the developer to a specific proprietary model or monolithic interface, it provides a modular framework for running multiple independent agent harnesses while maintaining unified audit logs and workspace state. Lionclaw is distributed under the MIT license and is maintained as a public Rust workspace on GitHub.
