Pilot Harness

English | 中文

A CodePilot-inspired desktop client and plugin suite for DeepSeek Harness.

Run the DeepSeek Harness plugin runtime as a focused native app, manage providers and multimodal models visually, and keep desktop additions isolated as ordinary Harness plugins.

Why Pilot Harness

DeepSeek Harness has a powerful “everything is a plugin” architecture, but its default experience is designed around a CLI-launched Web UI. Pilot Harness keeps that runtime model and adds the parts expected from a daily desktop product:

• A real desktop app — Electron packages the local Harness runtime for macOS, Windows, and Linux, owns native window behavior, and provides a recovery screen when startup needs attention.
• A calmer CodePilot-inspired interface — consistent tokens, radii, menus, hover states, settings cards, Markdown, conversation/trajectory navigation, and platform-aware title bars.
• Provider and model management — connect supported providers, declare an OpenAI-compatible endpoint, manage credentials separately from settings, browse the live model catalog, and identify image-capable models.
• Workspace context without clutter — project-aware conversation rows show branch, state, reminder summary, mode, and model details, while Files opens as a true right sidebar.
• Plugin-first extensions — the theme, Worktree sidebar, Schedule summary, and Session-log export remain Cordis/DeepSeek Harness rows rather than desktop-only business logic.
• Reversible customization — disabling the CodePilot theme row removes its product mark and visual overrides so the stock Harness presentation can take over again.

Pilot Harness does not replace the DeepSeek Harness agent loop, Session log, tool pipeline, provider contracts, or RPC implementation. Electron owns packaging and native integration; the composed Harness plugin tree remains the application runtime.

Quick Start

Download Pilot Harness

Download the installer for your system from GitHub Releases:

Platform	Download	Install and handle the security prompt
macOS (Apple Silicon)	DMG installer ZIP app	Open the DMG and drag pilot-harness.app into Applications. If macOS cannot verify the developer, use System Settings → Privacy & Security → Open Anyway. If it reports that the app is damaged, open Terminal and run: sudo xattr -rd com.apple.quarantine "/Applications/pilot-harness.app" open "/Applications/pilot-harness.app" Enter your login password when prompted; Terminal will not display it. Apple's security instructions.
Windows (x64)	EXE installer	Run the EXE. If Microsoft Defender SmartScreen says Windows protected your PC, first confirm that the file came from this Release, then choose More info → Run anyway. Do not disable SmartScreen globally. A managed computer may hide this option; contact its administrator instead. Microsoft's SmartScreen explanation.
Linux (x64)	AppImage DEB RPM	DEB: sudo apt install ./Pilot-Harness-Linux-amd64.deb RPM: sudo dnf install ./Pilot-Harness-Linux-x86_64.rpm AppImage: chmod +x Pilot-Harness-Linux-x86_64.AppImage, then ./Pilot-Harness-Linux-x86_64.AppImage. If the file manager blocks execution, enable Allow executing file as program in file properties. The preview packages are unsigned, so only accept a package-manager warning after confirming the official Release source.

All current preview installers are unsigned. Only override an operating-system warning for files downloaded from this repository's official GitHub Release; do not turn off platform security globally. Signing and notarization are planned for a future release.

After installation, open Pilot Harness, select a Workspace, then go to Settings → Providers to connect a provider and choose one of its available models. No separate DeepSeek Harness installation is required for the desktop app. Source setup and packaging instructions live in Development, not in the user installation path.

What is included

Area	What Pilot Harness adds	Ownership
Desktop shell	Native window, local runtime lifecycle, directory dialog, recovery, installers, and platform icons	Electron app
Visual system	CodePilot-inspired design tokens and component contracts	@deepseek-ai/dsh-client-ui-codepilot-theme
Workspace Files	Right sidebar, file count, branch summary, row actions, and @path insertion	@deepseek-ai/dsh-ui-worktree
Reminder summary	Active reminder count and nearest scheduled time in Session hover details	@deepseek-ai/dsh-ui-schedule-summary
Session export	Per-Session ZIP export from the Trajectory toolbar and /export	@deepseek-ai/dsh-session-log-export
Providers and models	Configurable adapter, credential/settings UI, live catalog, and multimodal labels	Existing Harness plugins plus the Pilot Harness desktop profile

The provider/model experience is deliberately a profile composition, not a new provider implementation. It mounts existing adapter, Settings, and Credentials contracts, then replaces the desktop placeholder only after a real provider advertises a usable model.

Use the plugins independently

The desktop client already includes every plugin below. If you use a local DeepSeek Harness Web profile instead, install only the feature you want with one command; each release asset is a prebuilt dsh.bundle, so no repository clone, YAML patch, or local build is required.

CodePilot theme

dsh plugin --profile web add https://github.com/op7418/pilot-harness/releases/latest/download/deepseek-ai-dsh-client-ui-codepilot-theme-0.1.0-rc.5.tgz

Applies the Pilot Harness visual system and product mark. Removing the plugin restores the stock Harness presentation. See theme details.

Files sidebar

dsh plugin --profile web add https://github.com/op7418/pilot-harness/releases/latest/download/deepseek-ai-dsh-ui-worktree-0.1.0-rc.5.tgz

Adds the Workspace-confined right file sidebar, file count, branch summary, row actions, and @path insertion. See Files plugin details.

Reminder summary

dsh plugin --profile web add https://github.com/op7418/pilot-harness/releases/latest/download/deepseek-ai-dsh-ui-schedule-summary-0.1.0-rc.5.tgz

Adds active-reminder metadata to Session hover details while the upstream Schedule plugin remains the reminder authority. See reminder plugin details.

Session-log export

dsh plugin --profile web add https://github.com/op7418/pilot-harness/releases/latest/download/deepseek-ai-dsh-session-log-export-0.1.0-rc.5.tgz

Adds per-Session ZIP export to the Trajectory toolbar and the /export command. See export plugin details.

Restart the Web profile after installation and use dsh --profile web --dump-config to confirm the added row. Files and Reminder summary require the Pilot Harness UI slot contracts included in Pilot Harness v0.1.0; older upstream Harness builds can install their bundles but cannot render those two UI contributions.

Remove a plugin with the same package name shown in its details page, for example:

dsh plugin --profile web remove @deepseek-ai/dsh-ui-worktree

Development

git clone https://github.com/op7418/pilot-harness.git
cd pilot-harness
pnpm install
pnpm run desktop:dev

Build an installer or run the desktop checks with:

pnpm run desktop:pack
pnpm run desktop:test
pnpm --filter @deepseek-ai/dsh-desktop run typecheck
pnpm --filter @deepseek-ai/dsh-desktop run test:e2e

The native CI matrix builds, tests, exercises the Electron flow, and packages on macOS, Windows, and Linux. Release candidates still need installation, title-bar, signing, notarization, and update checks on target machines.

For the underlying system, read the DeepSeek Harness architecture, development guide, and desktop architecture.
