梁子 · Desktop Pet · Liangzi Desktop Pet

A 父亲 (father) that lives inside the DeepSeek Harness Web GUI. It stands on the bottom edge of the window, breathes, blinks, strolls about with a real two-frame step, can be picked up, thrown and dropped, turns to look at your pointer, does small things on its own, falls asleep if you ignore it, says things out loud in Chinese with subtitles, and plays its own sound effects and background music.

Every sound it makes is on its own switch, and every asset ships inside this package — no network calls, no CDN, no build step, no external service.

DeepSeek 创始人的动漫化身，沉稳可靠的父亲。会走动、会说话、能拖动；和「大肥鱼」同时安装时，父女俩会打招呼、搭话，还能演一段小剧场。

What it does

16 drawn states	包括待机、眨眼、迈步（前脚）、迈步（过渡）、迈步（后脚）、开心、欢呼、说话、思考、比心、难过、生气、惊讶、睡觉、挥手、「嘘」的手势。 Every one is drawn from the original 梁子 artwork by image-to-image, so the face, outfit and palette stay exact — only the pose changes.
It moves like a character	A real three-frame walk cycle — contact, pass, contact — whose ground speed is derived from the step cadence rather than chosen freely, so the feet match the floor instead of skating. Plus idle breathing, blinking on an irregular cadence, hop, sway, nod, shake and squash-and-stretch. All of it CSS on top of the sprites, all of it respecting prefers-reduced-motion.
Physics when you grab it	Pick it up and it dangles against the direction you drag. Let go and it falls under gravity, lands with a squash and a spring, and throws a puff of sparkles if the drop was a long one. Its shadow shrinks and fades while it is in the air.
Small things on its own	Left alone it will 思考、「嘘」的手势、欢呼、比心、生气。 Each of those is a pose, a line and sometimes a little burst of particles.
Reacts to you	It turns to face your pointer when it comes near. Click it and it wakes up, reacts and says something. Poke it three times quickly and it gets annoyed.
Two pets, together	With both installed they do more than talk: they walk over to stand beside each other, turn to face whoever is speaking, hand each other things (a bowl of rice one way, a heart back), and perform the playlets side by side rather than from opposite corners.
Voiced dialogue	Every line is pre-rendered speech, not a beep. Speaking shows the subtitle in a bubble and switches the sprite to its talking state for exactly as long as the line runs.
Sound effects	Click, drag, greet, sparkle, heart, sleep and link cues, generated as one sound-effect group and picked per situation.
Background music	A calm instrumental loop written for this character. It starts only when you turn it on, and pauses automatically while the tab is in the background.
Family link	When 大肥鱼 is installed too, the two pets notice each other: they greet, call out to each other while you work, wander over to keep each other company, and can perform six father-and-daughter playlets with directed, alternating turns.

The character

梁子是社区给梁文锋起的称号，出自网友做的那个「滑动变祖器」——三十一档，从「小难梁」一路到「梁祖」，「梁子」正好是中间那一档；它同时谐音「结梁子」。

他是广东湛江吴川人，父母都是镇上的小学老师，十七岁以高考状元进的浙大。所以这个插件里他讲的是带广东口音的普通话，语速偏慢、声音不高。他说的台词，绝大多数是他真的讲过的：「我们不是有意成为一条鲶鱼，只是不小心成了一条鲶鱼」「创新首先是一个信念问题。首先是敢」「所有的套路，都是上一代的产物」「一件激动人心的事，不能单纯用钱衡量。就像家里买钢琴」。他也提那个滑块，提「梁性循环」，提那年在吴川踢的那场球。

他右手的姿势是那张照片里的「嘘」——这是他的标志动作，也是这个角色六种姿态之外多出来的那一种。

梁子 is the community's nickname for DeepSeek's founder, taken from a fan-made "Liang intensity calibrator" with 31 levels — 梁子 is the middle one, and it is also a pun on 结梁子, "to make an enemy". He is from Wuchuan in Guangdong, so his lines are delivered in Cantonese-accented Mandarin, slowly and quietly. Most of what he says are things he actually said in interviews. The finger-to-the-lips gesture is the one from the reference photograph — his signature, and the reason he has one pose the other pet does not.

The switches

Everything is a toggle in Settings → 桌宠 · 梁子, and the four you reach for most are also on the little toolbar that appears when you hover the character.

Switch	Default	What it does
显示桌宠	on	Hide the character without losing any setting
角色大小 / 不透明度	190px / 100%	How big and how assertive it is
自动走动	on	Whether it strolls along the bottom edge
小动作	on	Whether it fidgets, thinks, cheers and sulks on its own
对话气泡	on	Subtitle bubble above its head
主动搭话	on	Whether it speaks up on its own every so often
对话语音 + 音量	on / 80%	The voiced lines
音效 + 音量	on / 60%	The short interaction cues
背景音乐 + 音量	off / 35%	The looping instrumental
与大肥鱼联动	on	The cross-plugin link

Browsers refuse to play audio before the page has been interacted with. Until your first click or keypress the pet shows a 🔈 点一下开启声音 chip; one click anywhere unlocks audio for the session. This is a browser rule, not a plugin setting.

Install

The plugin is a standard DSH bundle: package.json declares dsh.bundle.patch, and cordis.patch.yml inserts the loader row that mounts both halves.

In the app — Plugins → Add plugin, and paste this repository's URL:

https://github.com/bauerelizabeth07139/dsh-pet-liangzi

From a command line (the desktop build reads the desktop profile):

dsh plugin --profile desktop add bauerelizabeth07139/dsh-pet-liangzi

Without git installed — pnpm resolves owner/repo with git ls-remote, which fails on a machine without git. Pin the tarball instead, which pnpm fetches over plain HTTPS:

cd "$HOME/.dsh/profiles/desktop"
node /path/to/dsh/runtime/pnpm.mjs add \
  "https://codeload.github.com/bauerelizabeth07139/dsh-pet-liangzi/tar.gz/<commit-sha>"

Then enable dsh-pet-liangzi on the Plugins page and open Settings → 桌宠 · 梁子.

Using it

• Click it — it wakes up, reacts and says something.
• Drag it — pick it up and drop it anywhere; the position is remembered.
• Hover it — a small toolbar appears with the voice, sound-effect, music and bubble switches.
• Leave it alone — after a couple of quiet minutes it falls asleep; any interaction wakes it.
• 演一段父女小剧场 in its settings starts a shared scene. With both pets installed they perform it together; with only one installed, it still plays its own half.

How it is put together

package.json          dsh.bundle.patch + dsh.client + the metadata cards read
cordis.patch.yml      the loader row that mounts both halves
lib/index.js          host half — config file, asset routes, HTML boot stamp
lib/client.js         browser half — the overlay slot, the pet, its audio
assets/sprites/*.png  six transparent states, palette PNGs
assets/voice/*.mp3    one file per spoken line
assets/sfx/*.mp3      one file per interaction cue
assets/bgm/*.mp3      the looping instrumental
assets/joint/*.mp3    the shared two-hander scenes
locale/{en,zh}.json   the plugin-card title and description
test/*.test.mjs       host and client checks, no browser needed

Host half. Serves GET/PUT /api/dsh-pet-liangzi/config (written to $DSH_HOME/dsh-pet-liangzi.json with an atomic temp-and-rename), GET /api/dsh-pet-liangzi/asset/<path> for every sprite and sample — with byte ranges, because <audio> seeks — and a diag route the browser posts to. It also stamps the config into the served HTML as window.DshPetLiangzi, so the pet is already on screen at first paint.

Browser half. Registers into the shell.overlay slot, which the app frame renders as a full-viewport pointer-events:none layer above the shell. The component renders one click-through root and re-enables pointer events on the character alone, so every click that is not on the pet still reaches the Harness. A single controller object owns position, the state machine, the speech queue and the audio channels; React only subscribes to state snapshots, which keeps the animation-frame loop off the render path.

The family link is a window.__DSH_PET_FAMILY__ bus carrying a protocol number. The first pet to load creates it, the second joins; a version mismatch degrades to "no partner" rather than throwing. Neither package imports, requires or reads the other — the bus is the whole contract, so either pet works perfectly alone. The playlets are a single mixed track generated with both voices and both speakers' turns, and the per-sentence timings that came back with it drive each pet's subtitle, so the two halves stay in sync without either one being in charge.

Troubleshooting

Symptom	Fix
No character appears	Check Settings → 桌宠 · 梁子 → 显示桌宠 is on, and that the bundle is enabled on the Plugins page.
Character is there, silent	Click the 🔈 点一下开启声音 chip, or click anywhere in the page once.
It never speaks	主动搭话 controls unprompted lines; clicking it always speaks. Check 对话语音 and its volume.
No music	背景音乐 is off by default — turn it on in the settings page.
It vanished after a window resize	Drag it back; it is clamped into the window rather than lost.
Both pets overlap	Drag one aside. Each remembers where you put it.
Nothing in the settings page	The Host half is not mounted — reinstall or re-enable the bundle.

If a pet fails to render at all, the browser half posts a report that you can read back with:

curl http://127.0.0.1:19387/api/dsh-pet-liangzi/diag

Companion plugin

Pet	Role	Repository
梁子	父亲	this one
大肥鱼	女儿	dsh-pet-dafeiyu

Install both to get the family link. Each is complete and independent on its own.

The character art is derived from the original 梁子 artwork by image-to-image, so the design, outfit and palette are the source images' — this package only re-poses them.

梁子的立绘是从那张照片做图生图转绘的写实风格：三维渲染质感、真实发丝、布料褶皱与镜片反光，成年男性的六头身比例。他与大肥鱼刻意不统一画风——一个是写实的大人，一个是Q版的小孩。
