Agents that build on your PC

Hand off a task and watch the agent plan, edit, run tools, and iterate until the job is done — with approvals for anything privileged.

Agent deepseek-v4-pro

Harden session cookies before ship

Sign cookies, set httpOnly, and cover the change with tests.

  • Read src/auth.ts
  • Edited src/auth.ts · +18 −6
  • Created src/auth.test.ts
  • Ran pnpm test

Cookies are signed and httpOnly. Four tests green — ready to review the diff.

Debug deepseek-v4-pro

Find why login 500s after the cookie change

Reproduce the HMAC failure and pin the secret in the test harness.

  • Searched src/**/*.ts · login
  • Read src/auth.ts
  • Ran pnpm test auth.test.ts
  • Edited src/auth.ts + Settings

Secret was undefined in tests. Guard added; suite is green.

Harness at the core

AI-powered chat needs a real coding surface. Monaco editor, explorer, terminal, git, and Harness agent tools stay in one window — packaged as AI Code Write for Windows.

Monaco IDE shell

Editor, file tree, diffs, terminal, and git — a focused desktop layout, not a browser tab.

DeepSeek Harness

Agent tools and sessions on loopback. deepseek-v4-pro by default, with a chat model picker.

Windows native

Packaged with Electron. Install once, keep your API key on device, auto-update in place.

Integrated terminal

Stay in the same window

Ctrl+` toggles a local PTY. The agent can run commands without flashing console windows; you review stdout in the panel under the editor.

Terminal & git

Built like an IDE, not a demo

Activity bar, explorer, terminal, git, plugins, models, and a command palette — arranged for focus.

Chat model picker

Switch deepseek-v4-pro or Flash from the agent input bar without opening the Models panel.

Thinking level

Auto, Off, Low, High, or Max in Settings — powered by the bundled dsh-thinking-levels plugin.

Git source control

Commit above the graph, branch picker, stash, and inline diffs — Cursor-style layout.

Plugin Market

Search, install, and remove Harness plugins with a cached catalog and background refresh.

Models panel

Favorites, custom providers, and session defaults — alongside thinking level in Settings.

Auto-update

Installed apps check the website feed. Restart when a new Windows build is published.

TypeScript JavaScript Python Go Rust C# HTML JSON

Plugins

Extend Harness without leaving the app

Plugin Market ships by default. Install vision, memory, reasoning, and agent bridges into the local web profile — GitHub-hosted packages work out of the box.

Plugins & models

Code with rich features

Whether you type the patch or the agent does, the same editor surfaces stay in reach.

  • Integrated terminal PowerShell or cmd inside the editor — agent shell tools run hidden on Windows.
  • Source control Git status, commit message above the graph, diffs, and the agent change list.
  • Command palette Keyboard-first Open Folder, search, settings, terminal, and updates.
  • Local-only harness DeepSeek Harness binds to 127.0.0.1. Your key never leaves the PC.
  • Approvals Privileged tools pause until you allow the edit or shell command.
  • Layout persistence Sidebar, agent panel, and terminal remember how you left them.

No extra dashboard. Install the Windows build, paste your DeepSeek API key, open a folder.
