Intro

DSH Chat Import imports conversation history with full context from other agents, turning it into a seamlessly resumable DeepSeek Harness session.

Now covers import from 21 agents: Claude Code, Codex, ChatGPT, Cursor, Gemini, Antigravity CLI, Reasonix, opencode, MiMo Code, ZCode, Grok Build, OpenClaw, Pi Coding Agent, Hermes, Kimi CLI / Kimi Code, Kilo Code, Qoder CLI, WorkBuddy, Qwen Work CN (千问办公) and DSH session logs.

Export back to: Claude Code, Codex, Kimi Code.

Supported Agents

Claude Code	Codex	ChatGPT	Cursor	Gemini CLI	Antigravity CLI

Install

dsh plugin --profile web add dsh-chat-import                    # npm package
dsh plugin --profile web add -w link:/path/to/dsh-chat-import   # local checkout (symlink)

Usage

1. Import — pick the conversations to import from the "Import sessions" panel in the bottom-right of the GUI and import with one click, or have your agent call the context tool:

import_chat({ format: "claude", path: "~/.claude/projects" })
import_chat({ format: "chatgpt", path: "~/Downloads/chatgpt-export/conversations.json" })
import_chat({ format: "local-jsonl", path: "D:\downloads\session.jsonl" })

Reasonix directory imports conservatively collapse only recovery ancestors proven by both a strict semantic prefix and an explicit parent_id lineage. Ambiguous or divergent files remain separate; use lineageMode: "physical" for one session per JSONL.

1. Resume — refresh the session list, open the imported session, and keep chatting from where the source left off.

2. Sync (optional) — the panel's "Sync" tab offers bidirectional incremental sync, off by default. Sub-agent conversations are filtered out by default in both directions.

3. Tool injection (optional) — the "Session Import" settings section exposes three injectTools levels: Minimal (default, keeps only the import_chat entry tool resident; low-frequency management tools stay out of context), Full (all 13 tools), and Off (invisible to the agent; the GUI panel still works). Tool descriptions are slimmed down to selection-time essentials; behavioral details ride along in execution results and error text, only when needed.

Full tool / command usage (parameters, examples, edge cases) lives in docs/USAGE.md.

Companion tool: config migration

Only need to migrate configuration (skills, hooks, global settings) rather than conversation history? dsh-movein handles config migration and complements this plugin -- DSH Chat Import only handles conversation history, and each tool works standalone. Its first-migration guide (中文) walks through a preview-first, apply-second, verify-each-step flow.

The combined flow of the two tools has not been jointly validated, and cross-linking is not a mutual endorsement; check sources, targets, duplicate-import and retraction boundaries for each tool separately.

This plugin's import_agents is a lightweight asset mover (it persists pi/opencode/Claude/Codex agents, prompts and skills as DSH skills); for full config migration (hooks, permission rules, settings), use dsh-movein.

Features

Capability	Entry points	Description
Batch import	import_chat (20 formats) · scan_discover · sidebar panel	Import 19+ sources with one tool; each conversation becomes its own session
Import history & purge	sidebar panel History tab	View imports.json records; remove plugin-created sessions (with confirmation)
Full-fidelity resume	Imported sessions	Tool calls & results, reasoning, titles, models and timestamps carry over
Export back	export_chat (format: claude / codex / kimi)	Serialize DSH sessions back to Claude / Codex / Kimi
Bidirectional sync	panel "Sync" tab	Incremental sync in both directions (external ↔ DSH), off by default

One documented exception to full fidelity: failed ghost retry steps. When a tool call never received its result and the very next step re-emits the same call id verbatim, the dead step is dropped at import — the result already pairs with the re-emitted call. Duplicate call ids in the imported log would hard-fail DSH's conversation folding (a second start for the same id), swallowing the whole trajectory after the first duplicate. See the droppedRetrySteps counter on the converter result.
