dsh-whale-arcade

English | 中文

Fill short waits for model responses, tool execution, and background tasks with three lightweight games. Open one instantly, close it to return to work, and keep the Agent running without adding anything to the conversation.

dsh-whale-arcade is a browser-game plugin mounted in DeepSeek Harness's global shell.overlay. The small whale in the bottom-right corner is its persistent launcher. The panel occupies only one corner of the workspace; closing it pauses and preserves the current round without interrupting the Agent.

Included Games

Game	Play	Controls
Whale Wave	Swim through underwater openings whose size, height shift, speed, and approach distance develop gradually	Click, touch, Space, Up, W
Blue Whale Treasure	Move horizontally to collect starfish, fish, crabs, and rare pearl shells while avoiding jellyfish and urchins; creatures have different scores and speeds	Left, Right, A, D, holdable touch controls
Whale Coast Run	Clear conches, urchins, coral towers, and wreckage with staged unlocks, low-obstacle pairs, and randomized short, medium, and long gaps	Click, touch, Space, Up, W

All three games support start, pause, resume, and restart after game over. The catalog displays the local Top 10 for each game, stored for the current browser origin. Ties are ordered by active play time and achievement time. Manual pauses, closing the panel, and hiding the browser tab do not count toward play time.

Install

Before installing, confirm that DeepSeek Harness starts with dsh web and that pnpm is available on PATH. Harness invokes pnpm for plugin management.

The plugin currently installs directly from GitHub and is not published to npm:

dsh plugin --profile web add github:jitengfei/dsh-whale-arcade
dsh web

If dsh web is already running, stop the old process, restart it, and refresh the browser. Open the Web address printed in the terminal. The whale in the bottom-right corner confirms a successful installation. The included cordis.patch.yml mounts the plugin automatically; no manual Harness configuration is required.

If dsh is not installed, first follow the official DeepSeek Harness run instructions. Users who run Harness through npx can instead use:

npx @deepseek-ai/dsh@0.1.0-rc.6 plugin --profile web add github:jitengfei/dsh-whale-arcade
npx @deepseek-ai/dsh@0.1.0-rc.6 web

The current code has been installed and run against DeepSeek Harness 0.1.0-rc.6. Harness remains a developer preview, and later versions may introduce incompatible changes.

Update or Remove

dsh plugin --profile web update dsh-whale-arcade
dsh plugin --profile web remove dsh-whale-arcade

Restart a running dsh web process after updating or removing the plugin. If you only use Harness through npx, replace the leading dsh in each command above with npx @deepseek-ai/dsh@0.1.0-rc.6; the same applies to the source-development commands below.

Develop from Source

Development requires Node.js 22.19+ within the 22.x line or 24+, plus pnpm 11.7.0:

git clone https://github.com/jitengfei/dsh-whale-arcade.git
cd dsh-whale-arcade
corepack enable
corepack prepare pnpm@11.7.0 --activate
pnpm install --frozen-lockfile
pnpm run check
dsh plugin --profile web add .
dsh web

pnpm run check runs type checking, tests, a clean build, and release-artifact validation. Open the address actually printed by the launcher.

Data and Runtime Boundaries

• All game behavior runs in the Web Client; the Node entry contains no game logic.
• The plugin registers no Host service, performs no RPC, reads no workspace files, and writes no Session events.
• It sends no telemetry, model requests, or player scores. Its only persistent data is the local scoreboard for the current browser origin.
• Runtime whales, marine life, obstacles, and scenes are drawn with SVG, CSS, or Canvas. The game loads no third-party images, audio, or fonts; the README banner is presentation-only and is not included in the runtime package.

Known Limitations

• Leaderboards are limited to the current browser origin. There are no accounts, cross-device synchronization, shared rankings, or server-side anti-cheat.
• Reloading does not restore an active round. Opening the whale again returns to the catalog, while completed local scores remain available.

Model Experience

None, as the arcade runs entirely in the browser and never enters prompts, messages, tool schemas, session logs, or model context.

KV Cache effect

None; the plugin never assembles or sends model-provider requests.
