Sync your DeepSeek Harness config across computers — one click. Move everything to a new machine, or keep two machines in step: plugin list, config patches, settings, and agent presets travel as a file-level snapshot; missing plugins are installed automatically.

多机同步 DSH 配置插件：一键搬家 + 自动同步。插件清单、配置补丁、全局设置、 Agent 预设按文件级快照同步，缺失的插件自动安装。

No chat commands, no OAuth, no build step. Everything lives in one settings panel (Settings → Sync). 纯设置面板操作，无命令、无 OAuth、零运行时依赖。

Features / 功能

One-click move / 一键搬家：install on a new machine → set the backend → click「拉取并应用」→ config, plugins and presets all arrive; new plugins are pnpm install-ed automatically.
Auto-sync on startup / 启动自动检测：DSH boots → plugin checks the remote → newer snapshot found → applies it (opt-out in the panel).
Two backends / 两种传输后端：
- Git repo (default): any git remote — GitHub / Gitee / GitLab / self-hosted / LAN path. Token optional (blank = system credentials / SSH); proxy configurable.
- Local folder: a plain directory (USB drive, shared folder, cloud-drive sync folder). No network needed.
File-level snapshots / 文件级快照：snapshot.json with per-file sha256 — only real changes travel; overwritten local files are backed up to ~/.dsh/.dsh-sync/backups/<timestamp>/ first.
Safe by default / 默认安全：credentials (.credentials.yaml) are not synced unless you tick the option; tokens stay on the local machine (git worktree .git-credentials, 0600); nothing machine-specific is hardcoded.
No auto-restart / 应用后只提示手动重启：after applying, DSH asks you to restart manually.

Install / 安装

dsh plugin --profile web add dsh-simple-sync
# or from GitHub
dsh plugin --profile web add github:LyaxZ/dsh-simple-sync

Then restart DSH. Requires DSH 0.1.1-rc.x or compatible; Windows / macOS / Linux.

Usage / 使用

Open Settings → Sync（设置 → 同步）.
Pick a backend and fill it in:
- Git: repo URL + optional token/proxy/branch — e.g. https://github.com/you/dsh-sync.git (a private empty repo works).
- Local: a folder path.
Click 测试连接 (Test connection) — first run prepares the worktree.
On the machine you configured first, click 立即推送 (Push now) to upload the first snapshot.
On every other machine, click 拉取并应用 (Pull & apply) — changes land, new plugins install, then restart DSH when prompted.

DSH startup auto-check applies newer remote snapshots by default; disable it in the panel. 凭据同步（.credentials.yaml）默认关闭，按需勾选。

How it works / 原理

Sync units（同步单元，白名单）: settings.yaml, .agent-presets/**, and per-profile package.json / cordis.patch.yml / pnpm-workspace.yaml under profiles/*. Everything else (node_modules, sessions, memory, data, lockfiles, generated cordis.yml) is excluded by construction.
A push builds snapshot.json = {meta:{machine,time,unitVersion}, files:[{path,sha256,content}]} and uploads it (git commit+push / file copy).
A pull fetches it and diffs against local state; apply writes changed files (backing up the old ones), then runs pnpm install in profiles whose package.json gained plugins.
Last-writer-wins; machine names travel in every snapshot for traceability.
Plugin state lives in ~/.dsh/.dsh-sync/state.json (backend config, last push/pull timestamps, options).

Development / 开发

node --test test/          # core + transport tests (incl. real bare-repo git)
node test/gateway-sim.mjs  # server-side gateway dispatch harness

test/gateway-sim.mjs imports the host's @deepseek-ai packages — create a temporary node_modules junction to your DSH install's node_modules to run it. The plugin itself ships with zero runtime dependencies.
