DSH Codex Pet
DSH Codex Pet is a community-maintained pet plugin for DeepSeek Harness (DSH), not an official OpenAI or DeepSeek AI product. From 1.0.1 it supports DSH 0.2.0-rc.1, 0.2.0-rc.2, 0.2.1-rc.1, 0.2.1-rc.2, and 0.2.1-rc.3. Earlier hosts and the 0.2.1 alphas are rejected by the version gate, so the plugin will not run; local pet settings and custom pets are not deleted.
Features
Keep a companion nearby while you work in DSH, follow task progress, and handle requests that need your attention. Choose a built-in pet or create your own with a Skill.
- Nine built-in pets: choose a companion and adjust its size in pet settings. Assets are bundled locally.
- In-page companion: keep a companion in DSH Web. Floating desktop pets require a desktop app with pet support.
- Multiple tasks at a glance: follow running tasks, completion, errors, and requests that need your attention. An empty notification list leaves only the pet visible.
- Act from the notification: open the associated task, stop its current turn, or handle supported approval, question, and plan requests.
- Quiet when you need it: dismiss an individual reminder without stopping its task; collapse or restore the pet through its menu or settings.
- Create your own companion: describe a pet in settings and start a dedicated DSH task using the bundled
hatch-pet Skill.
- Small interactions: drag to move, double-click to jump, and right-click for the pet menu.

Installation
Supported DeepSeek Harness versions: 0.2.0-rc.1, 0.2.0-rc.2, 0.2.1-rc.1, 0.2.1-rc.2, and 0.2.1-rc.3. Hosts before 0.2.0 (including the previously supported 0.1.2-rc.1, 0.1.5-rc.1, 0.1.5-rc.2, 0.1.5-rc.3, 0.1.7-rc.1, and 0.1.7-rc.2) and 0.2.1-alpha.1 through 0.2.1-alpha.5 are rejected by the version gate, and the plugin will not run. If you still use one of those hosts, install @michengai/dsh-codex-pet@0.1.19 instead of @latest. The version gate only refuses to load the plugin. It does not delete pet selection, position, or custom pets under DSH_HOME/codex-pet. Make sure the dsh command is available. The example uses the web profile; replace it with your target profile.
[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
$OutputEncoding = [System.Text.Encoding]::UTF8
dsh plugin --profile web add @michengai/dsh-codex-pet@latest --registry=https://registry.npmjs.org/ --ignore-scripts
Restart DSH after installation, then open Settings → Pets.
Usage
Open Settings → Pets (宠物 in the current UI), or open settings from the pet's right-click menu.
| Goal | Action |
|---|
| Pick a companion | Select a pet in settings and adjust its size. |
| Move or play | Drag the pet to move it; double-click to jump. |
| Read task updates | Read the notification bubbles; expand the list when several tasks need attention. |
| Continue a conversation | Click its notification or reply control to open the corresponding DSH task. |
| Handle a request | Open the request details and answer the supported approval, question, or plan prompt. |
| Stop a task turn | Click the stop control on that running task's notification. |
| Dismiss a reminder | Click its close control. The task continues running. |
| Hide or restore the pet | Use the right-click menu or pet settings. |
The pet is a notification and action surface. Start new conversations and write follow-up messages in the main DSH interface.
Create a custom pet
- Open pet settings, click the + icon (
创建), and describe the companion.
- Click Create in DSH (
在 DSH 中创建). The plugin opens a dedicated task and sends the bundled Skill instructions.
- Follow that task's progress. Creation uses DSH's configured model and image tools.
- Once the pet files are saved, refresh the pet library and select the new companion.
Creating pets requires an image-generation tool configured in DSH.
Updates and uninstallation
Use Settings → Pets → Check for updates. If automatic installation is unavailable, copy the update command shown in the dialog. Wait for running tasks to finish, then update and restart DSH as prompted.
To uninstall:
[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
$OutputEncoding = [System.Text.Encoding]::UTF8
dsh plugin --profile web remove @michengai/dsh-codex-pet
Custom pets are stored in .dsh/codex-pet/pets under your user directory by default; open the folder from pet settings. If DSH_HOME is set, pets are stored in its codex-pet/pets folder. Uninstalling keeps those files and settings.
