dsh-pet — Multi-pet companion plugin

English | 中文

A registry-driven desktop companion for DeepSeek Harness — the built-in whale girl plus any pet you drop in.

While the model thinks, you wait — your pet swims. It follows official session activity and switches animations while waiting, thinking, using tools, composing a reply, celebrating completion, or reporting failure; you can also pat its head, feed it dried fish, and watch its affinity grow. Pets are registry entries, not code: every pet is one pet.json manifest plus one atlas image, and the host discovers them at startup.

Re-implemented from the pet feature of the Codex desktop app, as an official DSH plugin shape (cordis bundle: host half + client half in one package).

Features

Feature	Description
Multi-pet registry	The host scans built-in `assets/`, the hatch-pet custom pets directory, and composed config entries; each pet is a manifest plus an atlas
Pet selection in settings	The plugin settings card lists every registered pet; switching persists and the sprite swaps immediately
Per-pet naming	Rename from the hover panel; each pet keeps its own name (stored per pet id, migrated from the legacy flat name)
State animation	Official session activity → 9-state animation: `thinking → running`, `tool → running-right`, `review → review`, `waiting → waiting`, `done → jumping`, `failed → failed`
Head-pat interaction	Click the pet → bubble feedback + affinity +1 (10s cooldown)
Feeding	Hover panel 喂食 (Feed) → consumes 1 dried fish + affinity +5 (30s cooldown)
Treat economy	Dried-fish stock (cap 20): +1 every 30 rounds of work, +1 every 300 minutes (5 hours) — 10x rarer than the original cadence
Affinity	+1 per round completed; 9 levels: 幼鲸 → 伙伴 → 挚友 → 深海羁绊 → 心有灵犀 → 传说羁绊 → 神话羁绊 → 永恒之契 → 鲸生共渡 (capped at 999,999,999)
Dragging	Hold and drag the pet to reposition; position persisted
Hide/Summon	Hover panel 隐藏 (Hide); after hiding, a 召唤{name} (Summon {name}) button appears
Witty remarks	Built-in remark library (10 lines per event) plus per-pet custom lines from a manifest remarks block — community PRs give their pet its own voice
Status bubbles	Each concurrently active top-level session gets its own bubble, stacked above the pet (up to 12); subagent sessions report through their spawning conversation and never occupy a bubble of their own; click a bubble to jump to its session; transient interaction feedback temporarily takes priority
Multi-session activity	The pet is host-global: the most recent meaningful event drives the sprite animation while every active top-level session reports its own state in a separate bubble; completed turns from every session (subagents included) contribute affinity and treats

Pet contract

A pet is a directory holding one pet.json manifest and one atlas image. Nothing else is required — no host or client code changes.

{
  "id": "whale-girl",                     // unique lowercase kebab id
  "displayName": "鲸鱼娘",                 // shown in the settings selector and panel
  "description": "A soft healing whale-girl.", // optional
  "spritesheetPath": "spritesheet.webp",   // atlas, relative to the manifest
  "cell": { "width": 192, "height": 208 }, // optional; defaults to the Codex contract
  "columns": 8,                            // optional; default 8
  "frames": [6, 8, 8, 4, 5, 8, 6, 6, 6],   // optional per-row frame counts
  "tracks": {                              // optional per-track rhythm overrides
    "idle": { "durations": [400, 400, 500, 400, 400, 500] }
  },
  "remarks": {                             // optional witty remarks (one line or a pool per slot)
    "pet": "摸摸水獭的头～",
    "feed": ["小鱼干真香", "再来一条～"]
  }
}

The atlas is an 8-column × 9-row grid (192×208 cells by default); rows are fixed in this order: 0 idle, 1 running-right, 2 running-left, 3 waving, 4 jumping, 5 failed, 6 waiting, 7 running, 8 review. Unused cells stay fully transparent.
The optional remarks block overrides the reaction bubbles the pet speaks on pet / petCooldown / feed / feedCooldown / noTreats events. Each slot accepts one line or a pool of lines (cycled round-robin); a declared slot replaces the built-in pool for that slot only. This is how community contributions give their pet its own witty voice.
frames counts the used columns per row (defaults to the hatch-pet contract table [6, 8, 8, 4, 5, 8, 6, 6, 6]); tracks overrides per-frame durations (cycled to the row's frame count), loop, and fallback per animation (defaults: everything loops; jumping and failed hold their last frame, then fall back to idle).

Where pets come from (later sources override earlier ones on id collision):

Built-in: assets//pet.json in this package.
Custom pets: ${CODEX_HOME:-~/.codex}/pets/ /pet.json — the hatch-pet pipeline stages its output there, so a hatched pet appears in the selector with no further wiring.
Composed: PetConfig.pets manifest entries passed to the plugin by the embedding application.

The registry is built once at host startup; add or change a pet, then restart dsh web.

Animation preview

The sprites are an 8-column × 9-row atlas (192×208 cells) generated by the hatch-pet pipeline; below are previews of each state:

idle	waiting	running	jumping

waving	review	failed	move left/right

Data flow

official session events (turn/step/chunk/tool) ----\
                                                    > PetService (host) /` — the plugin self-sufficiently provides its own API and assets (the same pattern as dsh-remote-web-ui's `/api/pair`).

## Install

Install the family aggregate package `@linxin666/dsh-web-ui-all` (all plugins and skins in one) or this plugin alone:

```sh
### From npm (recommended)
dsh plugin --profile web add @linxin666/dsh-pet

### From the repository (development)
git clone https://github.com/zhu1090093659/dsh-web-ui.git
cd dsh-web-ui
pnpm install && pnpm -r build
dsh plugin --profile web add link:$(pwd)/packages/dsh-pet

After installing, restart dsh web — your selected pet appears at the bottom-right of the interface. In link mode, pnpm build and refresh the page after a code change; no reinstall needed.

Development

pnpm build        # tsc -b (types+declarations) && tsdown (node half + browser bundle)
pnpm test         # vitest unit/component tests (registry / event projection / state / UI / ledgers)
pnpm prepare      # transpile-only build (no type checking, for consumer installs)
pnpm typecheck    # type check only

The browser bundle rides the window.__ModuleLoader__.load contract; React/cordis and so on resolve from the loader's module table (external); CSS Modules are inlined by lightningcss as ``.

Sprites and animation-track calibration

The built-in whale-girl atlas is generated by the hatch-pet pipeline as 9 states × 8 columns: assets/whale/spritesheet.webp (1536×1872, 8 columns × 9 rows of 192×208 cells) + assets/whale/pet.json. The frame count and rhythm of each row live in that manifest's frames and tracks fields — the whale girl carries its own slower healing durations, while pets without overrides follow the hatch-pet contract rhythm. Redoing artwork therefore only edits assets/whale/pet.json (row-order contract: 0 idle / 1 running-right / 2 running-left / 3 waving / 4 jumping / 5 failed / 6 waiting / 7 running / 8 review).
