Unship is an open-source agent harness and plugin integration framework developed by mbenhard. It is designed to package and orchestrate agent skills specifically for Claude environments and terminal workflows without adding unnecessary runtime overhead. In day-to-day operation, Unship functions as a lightweight skill provider and execution harness. It allows AI models, such as Claude Opus, to execute specific tasks, manage tool selection via hardened pickers, and interact with the local development environment through a structured plugin architecture. Unship distinguishes itself by focusing on minimal dependency packaging. By separating core plugin manifests from heavy test and development dependencies, it ensures that importing skills into Claude agent environments avoids bloated installs and cache pollution. The project is open source on GitHub and under active development with versioned releases focusing on skill hardening and workflow ergonomics.
