This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

OLEDCare

A DeepSeek Harness plugin (#dsh-plugin) that protects OLED panels during long agent sessions.

OLED burn-in protection for the DeepSeek Harness Web GUI (dsh web).

OLED panels wear where pixels stay lit for hours — exactly what a long agent session does to backgrounds, hairline borders, and bright text. OledCare pushes back on all three:

  • Nap mode — a true-black (#000) full-screen screensaver, so every background pixel switches fully off. It engages automatically after idle minutes, or on demand from the ☾ Nap button in the session header. A dim drifting clock (so the clock itself does not burn in) shows live agent status — agent is working / waiting for your input / idle — and any mouse or key input wakes the screen.
  • Pure-black surfaces — every dark-scheme background token goes to #000000; background pixels turn fully off instead of glowing dark gray.
  • Fainter static borders — hairline dividers sit at the same pixels all day, so their dark values go dimmer than the shipped palette.
  • Gamma-aware dimming — white text and bright accent tokens are scaled as a linear-light luminance ratio, so perceived contrast between text shades is preserved while total light output drops.
  • Idle/focus ladder — normal intensity → deep dim when idle or the window loses focus → nap. Three rungs, each configurable.
  • Hue rotation — the accent hue drifts through a ~12-hour cycle so static brand-colored icons wear every subpixel evenly.

Requirements

  • DeepSeek Harness (@deepseek-ai/dsh) with the web profile (dsh web)
  • pnpm on PATH (dsh plugin forwards to it)

Install

From GitHub:

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

From a local checkout:

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

Then restart dsh web and reload the browser tab. Open Settings → OLED Care in the settings left nav.

No build step runs on install: client.js ships in the harness browser-module format exactly as the browser loads it, so GitHub installs work without allowlisting a prepare script.

Uninstall

dsh plugin --profile web remove dsh-oled-care

Restart dsh web afterwards.

Settings

Three presets — Off, Balanced (default: black surfaces, 85% text, nap at 10 min), Maximum (70% text, deep dim at 3 min, nap at 5 min) — plus a Custom state that appears when you tweak any field:

FieldWhat it does
Pure black backgroundsEvery surface goes #000; background pixels turn fully off
Fainter static bordersDims hairline borders beyond the shipped palette
Text/accent intensityLinear-light scaling of white text and bright accents
Hue rotation~12 h accent-hue cycle for even subpixel wear
Deep-dim after idleMinutes without input before the deeper intensity applies
Deep-dim intensityThe dimmer level used while idle or unfocused
Deep-dim when unfocusedApply deep dim whenever the window loses focus
Auto nap after idleMinutes without input before the nap screen engages

A diagnostics box at the bottom of the settings page shows the live token layer, the resolved body background, the current dim rung, and the nap/idle state.

How it works

  • The package is a profile bundle: dsh.bundle.patch in package.json points at cordis.patch.yml, which inserts one plugin row. The client module system scans the row's dsh.client declaration into the browser roster and serves client.js at /plugins/dsh-oled-care/client.js.
  • All visual changes go through the client theme service as one replaceable token-override layer — the shipped theme is never edited, and removing the plugin restores it exactly.
  • UI is composed through the slot system only: shell.overlay (nap screen), conversation.session.header.actions (nap button), and settings.section (settings page).

Limitations

  • Settings live in memory: they reset to the Balanced preset when dsh web restarts.
  • The light color scheme is left essentially untouched — OLED care targets dark UIs.
  • Developed against dsh 0.1.0-rc.x. The browser module format (window.__ModuleLoader__.load) is an internal harness contract; pin your dsh version or check release notes when upgrading.
  • No network calls, no telemetry, no persistence, no access to conversation content.
