Fate / Twin Contract · Crimson Pact
An unofficial skin for the DeepSeek Harness (DSH) Web GUI, centered on Archer × Rin. Every character background is original generated fan artwork made for this project; no official screenshots, key art, or animation assets are included. This project is not affiliated with, sponsored by, or endorsed by TYPE-MOON, Aniplex, ufotable, or their related parties.
The skin natively follows Light, Dark, and System modes, works fully offline, and uses restrained motion. It is presentation-only: it does not read conversations, workspaces, or model configuration; it does not change theme preferences or localStorage; and it makes no network requests.

Install
Prerequisite: a working DSH Web GUI installation. Node.js 22 or newer is required only for development.
dsh plugin --profile web add github:Jayliu2025-vip/dsh-fate-twin-contractRestart dsh web after installation, then refresh any browser tab that was already open.
If your DSH setup requires manual wiring, add the complete record below to the Web GUI configuration. It exactly matches the repository's cordis.patch.yml:
- insert:
- id: ui-skin-fate-twin-contract
name: 'dsh-fate-twin-contract'Remove
First remove the complete insert record above from the DSH configuration, then run:
dsh plugin --profile web remove dsh-fate-twin-contractRestart dsh web and refresh the page. If DSH still reports a missing plugin, a stale cordis.patch.yml insertion remains in the configuration; remove it and restart again.
Privacy and accessibility
- Fully offline: no network requests and no access to data, conversations, workspaces, or model configuration.
- Does not change the DSH theme preference or write to localStorage or other local storage.
- Honors
prefers-reduced-motionby disabling decorative animation. - Supports
forced-colorsso system outlines and controls remain recognizable. - Removes character artwork on narrow and mobile layouts to preserve readability and working space.
