Blobby — VS Code Pet for DSH

English | 简体中文

Blobby is the official VS Code chat pet, ported to the DeepSeek Harness Web composer. It uses the official sprite sheets, accessories, frame timings, physics and interaction rules from microsoft/vscode, not a look-alike.

Attribution

This is an independent DSH port, not a Microsoft product. All Blobby sprite art, accessory atlases, animation timing, physics constants, achievement catalog, color palette and jump-game rules are derived from the official VS Code implementation and are used under the MIT license.

• The plugin icon is a composite of the official idle body and wizard-hat atlas with the official thinking bubble, recolored to a white body. The master is 144×144 (4× the 36px plugin-card artwork); icons/icon-{144,72,48,36,30}.png keeps native variants, and icon.svg embeds the 144px master.
• See NOTICE.md for the complete source-file list and Microsoft's MIT license text.

Thanks to the VS Code team and the original Blobby authors for the character and artwork.

What it does

• Sits on top of the composer and reacts to chat: pointer gaze, typing, thinking, clapping when the agent needs input, sleeping after 20 seconds, and the red-button celebration when a turn finishes.
• Drag it, flick it, throw it with Shift+←/→, hop with ←/→, catch it while it falls, and watch the despawn/respawn portal sequence.
• Right-click for Achievements, Play Jump Game, Go on the Run / Come Back, Grow / Shrink / Reset Size and Change Color.
• 14 achievements and 13 hats from the official catalog. Event-driven achievement tracking is intentionally not implemented: 13 achievements are unlocked by default and True Name is unlocked by /blobby, which opens the color tab.
• Stable/Insiders colors plus the eight official solid presets and a custom hex color (unlocked by /blobby). Hats and colors are applied immediately and persist.
• Blobby's jump game: Space to charge, release to jump, Left/Right to aim or hop, Escape to exit, with moving/crumbling platforms, wall bank shots, hop score and a persisted high score.
• Reduced-motion support, keyboard access, and a live status region for screen readers.

Install in a DSH profile

From the public npm package (after release):

dsh plugin --profile web add vscode-pet

Source install from the public repository (always available):

dsh plugin --profile web add github:96274zxc/vscode-pet

For the Electron desktop app, use Plugins → Add plugin → vscode-pet, or the same CLI with --profile desktop where the CLI is allowed to manage that profile.

For development from this checkout, link the package into a profile:

$node = "$env:USERPROFILE\.dsh\dsh-runtimes\dsh-primary-runtime\dependencies\node\bin\node.exe"
$pnpm = "$env:USERPROFILE\.dsh\dsh-runtimes\dsh-primary-runtime\dependencies\pnpm\bin\pnpm.mjs"
$profile = "$env:USERPROFILE\.dsh\profiles\desktop"
& $node $pnpm --dir $profile add "vscode-pet@link:C:/path/to/vscode-pet"

Then add vscode-pet to the profile's dsh.profile.bundles (or enable it in Plugins). Reload the page; if the Electron app does not recompose the loader live, restart it. To uninstall, remove the dependency and the bundle selection.

Build and test

node scripts/fetch-assets.mjs   # re-download the pinned VS Code assets
node scripts/build.mjs          # validate dimensions and build client.js
node --test test/*.test.mjs

client.js is generated. Edit files under src/ and rebuild; do not edit client.js directly. Assets are embedded as PNG data URLs so the plugin works under both http:// and the desktop dsh-app:// scheme without cross-origin canvas issues.

Controls

Input	Action
Click / Enter / Space	Random reaction; wakes Blobby; opens achievements while the star is visible
← / →	Hop along the composer
Shift+← / Shift+→	Throw toward a wall
Right-click / Shift+F10 / ContextMenu	Context menu
Drag	Move Blobby; release with speed to throw
Bounce while falling / Enter / Space	Bounce
/blobby	Unlock True Name and open the color tab
/vscode-pet	Show/hide Blobby (keeps the plugin installed)

Source and license

Sprite art, animation timing and interaction logic are derived from Microsoft VS Code commit ce233327f26ef7791b7fff0143c24e81a8126bd2, MIT licensed. See NOTICE.md for the exact paths. The plugin code is MIT licensed (see LICENSE).

Verification

The plugin was exercised in a temporary DSH web profile with headless Chrome: idle/typing/thinking/ clapping/sleep/reactions, drag and throw, despawn/respawn, the context menu, both customization tabs, hat and color selection, True Name unlock, and the jump game. docs/states.png is the state matrix and docs/achievements.png / docs/color.png are the customization panels from that run.
