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.jsondeclaresdsh.bundle.patch, thedsh-pluginkeyword, and anengines.dshrange. The repository topic isdsh-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
- Open Plugins → Install bundle in the DSH desktop app.
- Choose this repository directory, or a

persona:cetacea-lolisection.

- id: persona-cetacea

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.
