CloserAI

Local-first, model-agnostic, permission-transparent desktop AI workbench for
real Chat + Work + Code/Cowork outcomes. Built on DeepSeek Harness.

English · 简体中文

CloserAI is an open-source desktop client that hosts a DeepSeek Harness
process inside a hardened Electron shell. It is not a thin wrapper: it keeps DSH as the agent runtime
and adds a desktop supervisor, three permission-isolated working modes, local-first session storage,
OS-keychain secrets, and a plugin security model.

✨ What you get

• Hardened shell — context isolation, sandbox, strict CSP, locked-down navigation, single instance, deep links.
• Three permission-isolated modes — Chat / Work / Code, so the model only gets exactly the tools and files it should.
• Local-first sessions — every conversation is persisted under DSH_HOME, with history, projects, export/import, and restart recovery.
• Native desktop — system tray, crash/recovery notifications, launch at login.
• Transparent by design — a management page shows capability toggles, a per-mode permission manifest, and redacted diagnostics.
• Model-agnostic — DeepSeek, any OpenAI-compatible endpoint, or fully-offline Mock mode (no API key needed).

🚀 Quick start

Option A — install the Windows build (recommended)

1. Download CloserAI-0.1.0-Setup-x64.exe.
2. Verify the SHA-256 against SHA256SUMS.txt (Windows: Get-FileHash -Algorithm SHA256 .\CloserAI-0.1.0-Setup-x64.exe).
3. Run the installer, then launch CloserAI and pick Mock mode to try it with zero configuration.

The installer is not code-signed yet — if SmartScreen warns, choose More info → Run anyway,
and rely on the checksum. See docs/TROUBLESHOOTING.md.

Option B — run from source

pnpm install
pnpm check          # format + lint + build + typecheck + test
pnpm smoke          # end-to-end: onboarding → DSH UI → management page
cd apps/desktop && pnpm run dev

Requires Node.js >= 20.19 and pnpm 11. DSH is pinned to the exact runtime version in the lockfile.

🧩 Modes

Switch modes from the tray or the management page; each project pins a mode + working directory and is restored on relaunch.

🛠 Development

git clone https://github.com/sb1733831438-maker/DSH-closerAI.git
cd DSH-closerAI
pnpm install
pnpm check
cd apps/desktop
pnpm run pack     # build the Windows installer (release/CloserAI-*-Setup-x64.exe)

New features must keep pnpm check green (120 tests) and pnpm smoke passing. See
docs/PLUGIN_DEV.md for extending modes/presets.
