Introduction

During long intelligent agent conversations, the Web GUI of DeepSeek Harness keeps dark backgrounds, thin borders, and highlighted text at the same pixel positions for long periods. This is not a big issue for ordinary screens, but OLED panels are more prone to cumulative wear on these constantly lit pixels.

OLEDCare is a plugin for DeepSeek Harness (DSH) designed to reduce the brightness of pixels prone to “sticking” in dark interfaces without changing session operations. DSH’s philosophy is “everything is a plugin”; the community directory is an independent site with no official affiliation with DeepSeek or Hypersphere. Below is an introduction to OLEDCare’s positioning, capabilities, and installation method.

What is OLEDCare

OLEDCare is a DeepSeek Harness plugin (#dsh-plugin), maintained by domparent, under the MIT license.

It targets the Web GUI of dsh web, solving OLED burn-in issues during long intelligent agent conversations. The package name is dsh-oled-care, and the README title is OLEDCare.

Core Capabilities

OLEDCare primarily provides the following capabilities:

  • Nap Mode: A true black (#000) full-screen screensaver, triggered by idle or manually via the Nap button; optional 30-second wind-down.
  • Pure Black Surface: Sets the dark theme’s background token to #000000.
  • Darker Static Borders: Reduces the brightness of hairline dividers.
  • Gamma-aware Dimming: Scales white text and bright accent tokens by linear lightness ratios to reduce total luminance.
  • Idle/Focus Staircase: Deep dim or nap during normal intensity, idle, or unfocused states.
  • Hue Rotation: Accent hue drifts approximately every 12 hours.
  • Configurable Options: backgrounds, borders, text/accent intensity, hue rotation, deep-dim, auto nap, wind-down.
  • Settings Persistence: Uses browser localStorage with the key dsh-oled-care:v1; falls back to in-memory settings if storage is unavailable.

Installation and Usage

First, confirm that the environment meets the requirements:

  • DeepSeek Harness: @deepseek-ai/dsh
  • Web profile: dsh web
  • pnpm in PATH
  • Node engines: ^22.19 || >=24

Install from GitHub:

dsh plugin --profile web add github:domparent/OLEDCare

Install from a local checkout:

dsh plugin --profile web add /absolute/path/to/OledCare

The build step is not executed during installation; client.js is provided in the harness browser-module format.

After installation, restart dsh web, refresh the browser tab, and then open Settings → OLEDCare.

Typical Usage

The following explains the typical operational sequence:

  1. After installing the plugin, let OLEDCare dim the Web GUI’s background, borders, and text/bright tokens.
  2. When idle, enter deep dim or nap according to configuration.
  3. When you need a manual break, click the Nap button to enter the true black screensaver.
  4. If no longer in use, you can uninstall:
dsh plugin --profile web remove dsh-oled-care

Restart dsh web after uninstalling.

Use Cases and Notes

OLEDCare is suitable for:

  • Running long DSH agent sessions on OLED panels.
  • Needing to reduce the long-term brightness of backgrounds, borders, text, and bright accents in dark UIs.
  • Only wanting to perform client-side display settings without the plugin accessing session content.

Please note:

  • The plugin runs with the current dsh process permissions; check source code and license before installing.
  • Light themes are basically unaffected; OLED care primarily targets dark UIs.
  • No network calls, no telemetry, no access to conversation content.
  • Only uses browser localStorage to save plugin settings; falls back to in-memory settings if storage is unavailable.
  • This plugin was developed for dsh 0.1.0-rc.x; the browser module format is an internal harness contract. Pay attention to versions or release notes when upgrading dsh.
  • Installation depends on pnpm being in PATH.
