dsh-nushell

DSH ships with a built-in bash tool that only speaks traditional Shell syntax. For users who think in Nushell pipelines, structured tables, and typed data, every model-generated command often needs to be rewritten by hand. dsh-nushell is a Profile Bundle that swaps the underlying executor to Nushell while keeping the tool name and parameters exposed to the model completely unchanged, so the model simply writes Nushell directly.

Each command runs in a fresh nu --no-config-file -c process, meaning the user's config.nu and env.nu stay out of the call and every execution starts from a clean, predictable state. Background tasks, permission approval, sandbox isolation, timeouts, and output handling all delegate back to DSH's existing machinery, so the plugin never conflicts with core capabilities. Because no Shell state or variables persist between invocations, the workdir parameter serves as the sole location anchor.

If your daily or automation workloads already rely heavily on Nushell and you want the model inside DeepSeek Harness to produce Nushell-native commands out of the box, dsh-nushell is the most direct bridge with zero changes to DSH core and no extra scripting to maintain.
