dsh-session-sync

Sync Codex / Claude Code sessions into DeepSeek Harness as resumable sessions. 把 Codex / Claude Code 的历史会话同步到 DeepSeek Harness（DSH），导入后可直接续聊。

Features / 功能

• One-command import：/sync codex 自动扫描 ~/.codex/sessions，导入最新会话
• Auto-watch (realtime)：启动时自动监听 ~/.codex/sessions，Codex 会话一有变化就增量导入，无需手动操作
• Incremental：manifest 按 mtime 去重，只导入新增/更新的 rollout，不重复创建
• Full fidelity：用户消息、助手回复（含工具调用文本）完整保留，导入后可续聊
• Auto workspace grouping：按源项目目录（cwd）自动归入 DSH 工作区，与 Codex 项目视图一致
• Validated：写入走 DSH 官方 SessionPersistence 接口，通过全部 load 校验

Install / 安装

# install the plugin into your DSH web profile
cd ~/.dsh/profiles/web
pnpm add @z47_rose_1/dsh-session-sync

Or install directly from GitHub:

pnpm add github:NB4747/dsh-session-sync

Then add to cordis.patch.yml:

- insert:
    - id: session-sync
      name: 'dsh-session-sync'

Restart DSH (dsh web).

Usage / 使用

In the DSH Web UI, run:

/sync codex     # manual incremental import
/sync claude    # import Claude Code sessions (~/.claude/projects)
/sync watch     # start realtime watcher (enabled automatically on boot)
/sync unwatch   # stop the watcher
/sync push <sessionId>  # export new DSH turns back to the source Codex rollout (bidirectional)

Or with an explicit path (file or directory):

/sync codex C:\Users\you\.codex\sessions

Imported sessions appear under their source project workspace. Refresh the session list to see them.

Realtime syncing is enabled by default when the plugin loads — every new or changed Codex rollout / Claude Code session is auto-imported after a 3-second debounce. Set autoWatch: false in the plugin config to disable.

Development / 开发

pnpm install
pnpm run build

How it works / 原理

1. Parse a Codex rollout JSONL (~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl) — read-only
2. Map user turns + assistant replies into DSH SessionEvents
3. Write through DSH's sessionPersistence.create / append (zstd frames, contiguous seq, balanced turns)
4. DSH workspace bootstrap groups sessions by their source cwd

Roadmap / 路线图

• [x] MVP: /sync codex incremental import
• [x] V2 step 1: realtime auto-watch (boot-time, debounced)
• [x] V2 step 2: Claude Code source support (/sync claude, dual-directory watch)
• [x] V2 step 3: bidirectional sync (/sync push — DSH → Codex export)
• [x] V2 step 4: conflict handling (external-change detection, push→watch loop guard)
• [ ] GUI desktop app

Conflict handling / 冲突处理

• Push → watch loop guard: after /sync push, the manifest records the post-push mtime so the watcher skips the lines we just wrote — no duplicate sessions.
• External change detection: if the source rollout gained new turns on the Codex side since import, /sync push warns you and appends your DSH turns after them (chronological order preserved).
