The plugin is a straightforward CPU usage widget that reads standard Linux /proc and /sys/class/hwmon statistics via simple bash scripts. It performs no network access, no privileged operations, no persistence, and no destructive commands. The code is transparent and matches its documented behavior.

How this check works

This review combines the deterministic scan (the rule-based results above) with an independent look at the plugin's code by a language model. The model reads a trimmed sample of the repository's files, the manifest, and the README, then gives a plain-language risk level and a recommendation: install (no notable danger), review (look closer first), or avoid (clearly dangerous).

It runs on the same analyzed commit as the deterministic scan and is strictly advisory — it is not a security guarantee and never blocks a plugin by itself. A human moderator still reviews plugins before they are listed.

CPU Usage for Omarchy

An iStat Menus-inspired Omarchy Quattro bar widget for live CPU usage, history, temperature, top processes, load averages, and uptime.

CPU Usage preview

Features

  • Compact upright vertical CPU label and adjacent meter, centered in a standard icon slot
  • Bottom-up stacked meter with blue user time and pink system time
  • Sixty-second user/system history graph
  • CPU temperature, load averages, uptime, and logical CPU count
  • Top processes grouped by executable name, with application icons
  • Theme-aware native panel with keyboard and adjacent-panel switching

Install

omarchy plugin add https://github.com/egoist/omarchy-cpu-usage.git --enable

The widget lands in the right section of the bar. Move it if needed:

omarchy bar move dev.egoist.cpu-usage --section right

Configure

Set the fixed horizontal widget width (default 27, the standard icon slot):

omarchy bar set dev.egoist.cpu-usage width 27

Set the number of process rows (default 5, range 1–10):

omarchy bar set dev.egoist.cpu-usage processCount 5

How the metrics work

Overall user and system usage are calculated from deltas in Linux's aggregate /proc/stat CPU counters. The bar keeps the latest 60 one-second samples for its panel graph.

Per-process usage is measured across a live 650 ms sample of each process's user and system CPU counters. Percentages use one logical CPU as 100%, so a multi-threaded process can exceed 100%.

Temperature prefers CPU-specific hwmon sensors such as k10temp and coretemp, with the first readable hwmon temperature as a fallback.

Dependencies and security

The plugin runs unsandboxed with your user permissions, like every Omarchy shell plugin. It does not use sudo, install packages, start services, or access the network.

It reads Linux's /proc and /sys/class/hwmon statistics and uses commands included with a standard Omarchy installation: Bash, awk, sort, head, getconf, date, and jq.
