[!WARNING] This project is an independent community project. It is not an official DeepSeek project and is not maintained by DeepSeek. For any information, help or feature suggestions, feel free to leave an issue!
[!NOTE]
- Quickly view your API Key balance
- Built-in Trace support
- Automatically download Runtime (distributed via CNB) when DSH is not present
- i18n support
More comprehensive features: session state, IDE context, Runtime activity, approvals, Trace and file changes are all integrated into the extension. Easier to use: there is no need to understand npm at all!
Feature Architecture
The chat interface is a React Webview backed by a typed, full-state bridge. The Extension Host is responsible for VS Code APIs, Runtime RPC, credentials, secure Markdown rendering and action validation.
Installation

Detailed Description
If dsh reports a missing or invalid API Key, click Key in the chat header or run DSH: Configure API Key. The key is passed to dsh's credential service, and an encrypted copy is stored in VS Code SecretStorage for the balance indicator. It is never written to prompts, extension state or logs.
DSH: Manage Providers from the chat menu or Command Palette lets you inspect whether a Provider is enabled, its configuration and credential source, set or remove API Keys, and open the official Harness configuration file for advanced editing. DSH: Manage Agent Presets lists system and user Presets, reports broken compositions, opens a read-only composition snapshot, and lets you copy, edit, delete or make a Preset the default through Harness-owned operations. DSH Workspaces are discovered from their directories; DSH: Manage Workspaces can rename or remove groups and reorder Workspaces or their Sessions. Removing a group never deletes its directory or Session logs.
Multiple VS Code windows preferentially share one local Harness Runtime. A Runtime started by the extension publishes its random loopback port through a process lock; later windows validate it with host.describe before connecting, preventing competing writers from touching the same Session storage.
Development
npm install
npm run check # TypeScript check
npm run compile # Build to dist/
npm run package # Compile + vsce package
VS Code is recommended.

Thanks to dsh-reasoning-effort for the chibi runner sprite reference and asset used by the reasoning-effort control. The conversation outline also takes inspiration from the dsh-milestone project; its Hub-style milestone idea led to the native VS Code TreeView implementation here.
