DeepSeek Harness Companion for VS Code

Bring local DeepSeek Harness sessions into VS Code. Follow streaming replies, thinking, tools, approvals, questions, and conversation history beside your code.

Use the companion

• Create, switch, resume, and archive sessions by workspace.
• Send text, images, and supported files; reference files and sessions with @.
• Use the models, providers, permissions, and agent options supplied by the connected DSH.
• Open produced files through VS Code, and use local templates, checkpoints, Changes, and task views when available.

Available operations depend on the connected DSH runtime. Unsupported capabilities are shown explicitly; exact compatibility and evidence are documented in the repository.

Get started

1. Open the DeepSeek Harness view.
2. If DSH is missing, use the guided installer or copy its exact install command. You can also select an existing executable.
3. Choose or create a workspace, start a session, and send a task.

The Chat view is registered in VS Code's Secondary Side Bar by default (on the right in the default workbench layout). VS Code may keep a previously saved view location after an upgrade.

The extension discovers compatible local instances before starting one. Connection modes let you attach only, start an isolated extension-owned instance, or probe one configured loopback endpoint. It never stops an external DSH. Runtime updates install a verified exact version and do not restart external processes.

Privacy and help

DSH connections, credentials, file access, and process ownership stay in the VS Code Extension Host. The Webview receives no secrets or direct filesystem/network access; diagnostics are redacted.
