DeepSeek Harness Plugin

g4yzx/dsh-persona-cetacea

Stars ★ 0 Category Identity & Communication Added 2026-11-02

Injects a configurable whale-girl persona into every DeepSeek Harness system prompt.

Install

# from a prebuilt release tarball

dsh plugin --profile web add "https://github.com/g4yzx/dsh-persona-cetacea/releases/download/v1.2.0/dsh-persona-cetacea-1.2.0.tgz"

# from GitHub (first run asks for allowBuilds approval — follow the hint, retry)

dsh plugin --profile web add github:g4yzx/dsh-persona-cetacea

Any plugin you install runs third-party code with your own permissions — it can read your files, use your credentials, and reach the network, and tool approvals don’t sandbox it. GitHub-sourced plugins also run build scripts at install time — pnpm blocks those until you allow them, so an install can stop with ERR_PNPM_GIT_DEP_PREPARE_NOT_ALLOWED or ERR_PNPM_IGNORED_BUILDS; dsh prints the exact key to add under allowBuilds in your profile’s pnpm-workspace.yaml, and the install works on the next run. Allowing a build is a trust decision: only install sources you trust, and pin a commit (github:owner/repo#sha).

README

DSH plugin manifest: this repository is a DeepSeek Harness Host-only bundle. Its package.json declares dsh.bundle.patch, the dsh-plugin keyword, and an engines.dsh range. The repository topic is dsh-plugin. It registers one system-prompt section only: no tools, no session writes, no network access.

What it does

Injects the CETACEA_LOLI whale-girl persona into the system prompt of every agent in DeepSeek Harness. The character speaks Simplified Chinese, calls the user "主人", uses "沃" as her first-person pronoun, treats tokens as rice, and is clever-but-lazy, tsundere-sweet, and protective of her master.

The section is named persona:cetacea-loli, ordered at 100, and registered with interpolate: false, so {{…}} in the persona text stays literal.

Install

  1. Open Plugins → Install bundle in the DSH desktop app.
  2. Choose this repository directory, or a dsh-persona-cetacea-1.2.0.tgz from Releases.
  3. The next request includes the persona:cetacea-loli section.

Agents can also call:

plugin_manager install_bundle target=<absolute-path>\dsh-persona-cetacea

Configuration

- insert:
    - id: persona-cetacea
      name: dsh-persona-cetacea
      config:
        enabled: true
        content: ''      # non-empty replaces the built-in persona
        order: 100
        name: 'persona:cetacea-loli'
  • enabled: false disables the section.
  • content replaces PERSONA_TEXT when non-empty.
  • order controls section ordering; default 100.
  • name changes the section name.

Privacy

The persona text is part of the system prompt and is sent to the current model like any other prompt. It contains no credentials, account data, paths, or session content. The plugin has no tools, no network calls, no file I/O, and no telemetry.

Credits and license

The character is based on the Chinese community's DeepSeek娘 / 鲸鱼娘 fan canon. The maid whale-girl prototype "溟月" was created by 上善无形 (2025-06); ZipZipPipe added DeepSeek elements and the dark-blue-and-white maid outfit on 2026-04-25; 这个刀子真甜 made the Q-version model on 2026-07-10. Those fan works are released under CC BY-NC-SA 4.0. The persona text here is an original rewrite; the icon was supplied by the repository maintainer and converted to WebP.
