dsh-plugin-claude-import
Import Claude Code sessions (~/.claude/projects/*.jsonl) into DeepSeek Harness as continuable context — an auto-summary chain, the last task, the file footprint, and the tail state — rather than an event replay.
The plugin is the DSH-native port of claude-code-to-dsh (a zero-dependency Python CLI that produces the same seed / markdown documents).
Features
- Agent tools (host half):
claude_session_list — list sessions under ~/.claude/projects (id / project / title / mtime / size / message stats).claude_session_import — import one session as a seed context block (paste-ready for a new session) or a full markdown continuation document; with createSession=true it creates a new DSH session in the Claude session's project directory and delivers the context as its first message.
- Web GUI (client half): a "Claude 导入" action in the conversation header — enter a session id (empty = most recent) and the plugin creates a new DSH session, opens it, and seeds the import instruction.
Requirements
dsh ≥ 0.1.0-rc.6 (npm: npx @deepseek-ai/dsh web), Node.js ≥ 18.- A local Claude Code installation with sessions under
~/.claude/projects (the plugin reads them from the dsh host process).
Installation
One command (bundle flow, recommended)
dsh plugin --profile web add dsh-plugin-claude-import
The package declares dsh.bundle, so dsh plugin links it, appends it to the profile's bundles, and applies its patch layer (which inserts the plugin row). Restart dsh web and verify:
dsh --profile web --dump-config | grep claude
Manual (into an existing profile)
cd ~/.dsh/profiles/web
pnpm add dsh-plugin-claude-import
Then register the row in ~/.dsh/profiles/web/cordis.patch.yml:
- insert:
- id: claude-import
name: 'dsh-plugin-claude-import'
Restart dsh web.
From GitHub
No build step is required (plain JS), so a git install works without a prepare script:
dsh plugin --profile web add github:changhang155/dsh-plugin-claude-import#<sha>
If pnpm refuses to run scripts, allow the build in the profile's pnpm-workspace.yaml (allowBuilds: dsh-plugin-claude-import: true) and re-run the add.
Peer dependencies
The plugin uses @deepseek-ai/cordis, @deepseek-ai/dsh-tools, @deepseek-ai/dsh-host-apiproxy, and @deepseek-ai/schemastery as peers, resolved from the dsh installation. When installing into a fresh profile, ensure those are present (the web profile already bundles them; a bare profile may need pnpm add of the peers or symlinks to the dsh install's node_modules/@deepseek-ai).
Usage
From the agent: ask for the list, then import:
请列出 Claude Code 的历史会话。
把会话 <id> 导入为 seed,并在其项目目录下新建一个 DSH 会话。
The tool claude_session_import accepts:
| parameter | meaning |
|---|
sessionId | 8-char prefix, full id, or a full .jsonl path |
format | seed (default) or markdown |
createSession | create a new DSH session in the Claude project dir and deliver the context as its first message |
From the Web GUI: click Claude 导入 in the conversation header, optionally type a session id, and press 导入. A new session is created and opened; its agent reports the title, touched files, and open threads.
Compatibility
DeepSeek Harness is in developer preview — compatibility-breaking changes are expected. This plugin targets the 0.1.0-rc.6 npm line (peer ranges use ^0.1.0-rc.6). If a later rc breaks the client contract (window.__ModuleLoader__ / slot injection), update the plugin or pin your dsh version.
The import is heuristic: session titles come from Claude's ai-title / summary rows; the "touched files" list only covers Write/Edit (and Read) tool calls; local-command-mode sessions (mostly command injection) are detected and annotated rather than misread as conversation.
Development
git clone https://github.com/changhang155/dsh-plugin-claude-import
cd dsh-plugin-claude-import
npm test # node --test tests/ (no dependencies)
node --check lib/index.js lib/client.js lib/parse.js
Layout:
lib/index.js — host half: registers the two agent tools (defineTool from @deepseek-ai/dsh-tools).lib/client.js — client half: the Web GUI dock (loaded via the client runner).lib/parse.js — pure-Node Claude Code JSONL parser (no dependencies).cordis.patch.yml — the bundle patch layer that activates the plugin.
