Ratel Lumina

English · 中文 · npm · Changelog

A smoother flow from composing a message to sending it and reading the reply.

Ratel Lumina adds customizable motion to DeepSeek Harness. A soft glow marks the focused composer, messages travel as a droplet, a dissolve or a little ghost, and caret feedback follows the reply. These details give everyday conversations a continuous visual rhythm.

Works with the DSH desktop and Web / PWA clients. Adjust the motion to your preference or switch it off at any time.

Why Lumina

• Connected feedback. The composer, send button, message transition and streaming caret share a consistent use of light and timing.
• A choice of expression. Send with a droplet, dissolve or ghost transition, or turn transitions off and keep the lighter feedback.
• Control over the motion. Choose an intensity, color preset and individual effects. Saved settings apply immediately.
• Your workflow stays intact. Lumina does not change models, requests or message content, delay submission, or block typing, clicking and selection.
• Lightweight and optional. Built with CSS and native SVG, without an additional animation framework. A master switch turns it off, and system reduced-motion preferences are respected.

In use

Moment	Feedback
Composing	A mixed-color rim, with a soft halo and flowing light when focused
Pressing send	Press feedback and a brief light pulse
Sending a message	Droplet, dissolve or ghost transition, or no transition
Waiting for a reply	Streaming caret feedback and session activity indication
Opening a new conversation	Brand and hero entrance motion

Choose a send transition

Droplet is the default. The text gathers into a drop, merges with the composer edge, detaches, travels to the message and unfolds as a coherent block.

Dissolve disperses the characters and resolves the message from blur into clear text.

Ghost carries the text with a rounded, one-piece little spirit. Its cape hem flutters while it floats, then the message fades in as a whole on arrival.

Existing valid mode choices are preserved when the plugin is updated.

Install and update

Install DeepSeek Harness first, then add Lumina to the profile you use:

dsh plugin --profile <profile> add @ratel-works/dsh-lumina

Replace <profile> with your profile, such as desktop or web. Run the same command to update, then fully quit and reopen the client to load the new plugin code.

The current development and verification baseline is DSH 0.2.1-rc.2. Client updates can change the UI interfaces used by the effects, so compatibility needs to be checked again after an upgrade.

Settings

Open Lumina / 流光 in DSH settings to choose a send transition, intensity and color preset, or disable individual effects. Save your changes to apply them immediately, without restarting.

Turn off the master switch to restore the original interface. When system reduced motion is enabled, Lumina reduces or disables animations automatically.

Saved settings apply immediately; installing or updating plugin code requires a full client restart.
