dsh-workspace-enhancement
English | 中文
DeepSeek Harness plugin: local and remote (SSH) workspaces in one place. Remote execution uses a single SSH connection (multi-hop jumps allowed); bash, files, PTY, and LSP share that link. Multi-machine registry with TOFU host keys and OS keychain. Web UI for adding workspaces and editing machines. Also ships 3 sw_* model tools. Built on ssh2.
Features
| Feature | Description |
|---|
| Remote workspaces | ctx.subprocess + ctx.fs remote providers: one SSH chain (multi-hop) runs bash / files / PTY / LSP. Tools on those seams switch to remote with no code changes |
| Multi-machine registry | remote-workspaces/machines.json + ssh://<id>/<path> routing; recognizes ~/.ssh/config aliases |
| Security | TOFU host keys (accept-new / verify / off); per-machine OS keychain (DPAPI / security / secret-tool); credentials redacted in error messages |
| Web UI | Add workspace (connection sidebar + remote directory browser); machine settings (CRUD / test / set current / forget fingerprint) |
| Model tools | sw_status, sw_connect (save:false for temporary), sw_pick_workspace |
Architecture
flowchart LR
subgraph local["Your machine"]
agent["agent loop<br/>orchestration · memory · LLM calls"] --> seam["this plugin<br/>ctx.subprocess · ctx.fs"]
end
subgraph remote["Remote host"]
run["bash · files · PTY · LSP"]
end
seam -- "one SSH connection (multi-hop jumps)" --> run
No DSH install on the remote: the model orchestrates locally, commands run remotely, results come back into context.
Install
dsh plugin --profile web add <this-repo-path> # from source: npm run build first (host loads lib/)
