dsh-cd: DeepSeek Harness Working Directory Switching Plugin

dsh-cd is a plugin for DeepSeek Harness (DSH) designed to solve path resolution problems caused by a frozen session working directory. It provides two levels of operation: a lightweight “working-base override” that only changes the default resolution base for file tools, is reversible, and does not change session identity; and a heavier “true workspace migration” that actually changes session identity, storage location, and skill discovery, requiring explicit user consent. The plugin can be invoked by the model and by users via the /cd command, supports reverting directories, and inherits subagents, making it suitable for frequently switching contexts or permanently relocating projects.
