--- ## 🤔 Why dsh-codex-sync? When using OpenAI Codex, developers build up significant workflow assets: 1. **Rich project chat histories** with complete code contexts, architecture decisions, and debugging steps; 2. **Custom Skills libraries** under `~/.codex/skills` with tailored instructions and scripts; 3. **Configured MCP toolchains** for databases, web searches, and browser automation. When adopting or exploring **DeepSeek Harness (DSH)**, developers typically face major friction: - **Lost conversation history**: Incompatible session formats prevent resuming past Codex tasks in DSH; - **Configuration duplication and drift**: Skills and MCP servers must be manually recreated and maintained in two separate tools; - **One-way dead ends**: Most migration scripts are one-time destructive copies that offer no clean way to safely bring DSH continuations back to Codex. **`dsh-codex-sync` eliminates this friction completely.** It is not a throwaway migrator, but a production-grade, continuous two-way bridge between Codex and DSH. --- ## ✨ Key Highlights ### 1. 💬 Two-Way Safe Project Chat Portability (Codex ⇄ DSH) - **Import from Codex**: - Browse conversations grouped by workspace folder in an intuitive project tree; - Preserves user prompts, assistant outputs, reasoning traces, and tool-call trajectories; - Automatically attaches imported sessions to matching workspaces for **seamless continuation**; - Incremental re-import: Codex conversations continued after the initial import are marked as `updated` and append only new turns without creating duplicate sessions. - **Export to Codex**: - Export DSH native conversations or continuations back into Codex; - Automatically matches Codex's workspace catalog, gracefully locking unknown directories to prevent orphan threads; - Creates clean, standalone Codex rollouts (`history_mode: legacy`) and SQLite index entries **without modifying or overwriting original Codex histories**; - View and continue chats in Codex immediately after restarting the Codex app. - **Sub-Agent Thread Filtering**: - Hides internal sub-agent threads by default to keep the conversation list focused; - Easily expand and nest sub-agents under parent threads for selective, independent export. ### 2. ⚡ Live First-Class Skills Mounting - Mounts `~/.codex/skills/*/SKILL.md` directly into DSH's native skill catalog; - Full support for nested directory resources and multi-file skill bundles; - **Zero-restart updates**: Edit a skill file on disk, and DSH recognizes the change on the next turn. ### 3. 🔌 Automated Bidirectional MCP Mirroring - **Codex → DSH**: Watches `~/.codex/config.toml` live, dynamically mirroring `[mcp_servers.*]` to DSH with conflict avoidance and stderr silencing; - **DSH → Codex (Reverse Bridge)**: Single-command setup (`npx dsh-codex-sync codex-install`) equips your Codex agent with tools to search, inspect, and install DSH plugins. ### 4. 🎨 Native Modern UI Experience - **Adaptive Sidebar Trigger**: Sits right beside the workspace header when expanded, and aligns below the search button when collapsed; - **Centered Modal Panel**: High-contrast, backdrop-blurred settings card with intuitive action cards, real-time switch feedback, and zero UI cutoff; - **Polished Design Integration**: Uses native DSH design tokens (`--dsw-alias-*`), pure CSS transitions with zero hover artifacts, and responsive text truncation. --- ## 📦 Quick Start ### 1. Install in DSH Install via DSH Plugin Market (recommended): ```bash dsh plugin --profile web add dsh-codex-sync ``` Or configure inside your profile's `cordis.patch.yml`: ```yaml - insert: - id: codex-sync name: dsh-codex-sync config: maxSkills: 30 mcpMirrorDeny: - node_repl mcpMirrorSilent: - exa ``` ### 2. Configure Codex Reverse MCP Bridge (Optional) ```bash # Register [mcp_servers.dsh-plugins] in ~/.codex/config.toml npx dsh-codex-sync codex-install # Run diagnostic health check dsh-codex-sync doctor ``` --- ## 🎛️ Sync Settings & Toggles Click the **Codex Icon** in the sidebar to open the centered control modal: | Section | Item | Command / Config Key | Description | |---|---|---|---| | **Actions** | Import from Codex | `/import-all` | Open project picker to import chats into DSH | | | Export to Codex | `/export-codex` | Export DSH chats into new Codex conversation copies | | | Repair sessions¹ | `/repair-sessions [--fix]` | Scan stored session logs for replay damage and heal them in place (see below) | | | Mirror status | `/mcp-status` | Modal overview of MCP servers, health, and statuses | | | Refresh states | `/codex-settings` | Re-sync all switch states from the host | | **Features** | Import commands | `enableImport` | Enable `/import-codex` slash command family | | | Auto import | `autoImport` | Automatically import new Codex chats on startup | | | Instructions | `enableInstructions` | Inject `instructions.md` / `AGENTS.md` into prompt | | | Config summary | `enableConfig` | Inject `config.toml` model settings summary into prompt | | | Skills | `enableSkills` | Register `~/.codex/skills` as live DSH skills | | | MCP mirror | `mcpMirror` | Auto-mirror `[mcp_servers.*]` (applies immediately) | | **Language** | Language Switcher | `Language` | Toggle between 简体中文 / English | > ¹ A subtle hint at the bottom-left of the settings modal links imported-chat errors to this command. --- ## 🩺 Troubleshooting: `token meter` / replay errors on imported chats **Symptom** — switching the model or running compaction on an (imported) conversation fails with: ``` command.execute failed: internal: token meter: assistant/message at seq N has no matching step/start event corrupt session log: seq gap in committed region at line L ``` **Why** — DSH's token meter validates the whole event log via cold replay when the model changes (provider usage anchors become invalid). Logs written before v1.6.0 lacked paired `step/start…step/end` markers, and mixed logs can carry stale seq citations — both fail loud only during that replay. **Fix** — run this in any DSH chat (or `dsh-codex-sync repair-sessions --fix` in a terminal): ``` /repair-sessions --fix ``` The repair merges seams, inserts missing step markers, remaps citations, renumbers sequences, validates every candidate with the real `@deepseek-ai/dsh-token-meter`, and keeps a `.bak` next to each repaired log. Imports created by **v1.6.0+** are replay-safe by construction, so this should never trigger again. --- ## 🤖 Built-in Agent Skill (`codex-sync`) This package bundles a first-class `codex-sync` skill. Your DSH AI Agent can operate synchronization tasks on your behalf: - *"Dry-run importing my Codex conversations"* → runs `/import-codex --dry-run` - *"Check current MCP mirror status"* → runs `/mcp-status` - *"Turn on auto-import"* → runs `/auto-import on` --- ## 📄 License [MIT License](LICENSE) © 2026 Walvez
