Prompt Cache

iCUE widget In development

A countdown for Claude's prompt cache, and how much money it saved you today and this week.

The Prompt Cache widget: a ring counting down from 41:56 marked warm, money saved this chat, today and this week, and a 7 day bar chart.
Prompt Cache at medium size: the ring and the savings.

What it does

  • A ring that counts down until the cache goes cold, so you know when to reply.
  • Warm, cooling and almost cold states you can read at a glance.
  • What the cache saved this chat, today and this week, with the hit rate.
  • A 7 day chart of savings. Turn it off in the widget settings for a calmer look.

Set it up

  1. Open iCUE and select the Xeneon Edge.
  2. Open the widgets section and press the plus button.
  3. Pick the .icuewidget file you downloaded, or install it straight from Elgato Marketplace inside iCUE once it is listed there.
  4. Drag the widget into a slot. Hold it to open its settings: colours, transparency and what it shows.

Permissions

iCUE asks you to approve these when you install. Here is what each one is for. Everything stays on this PC unless a line says otherwise.

Read one status file <Home>/.session-hq-status.json
Reads the file Session HQ writes with your usage, chats and repo states. Why: It is where the numbers come from. Nothing else in your home folder is read.
File watcher iCUE File System plugin
Gets told the moment that file changes. Why: Updates land instantly instead of on a timer, with less work for your PC.
Local helper app localhost:13509
Talks to a small helper app on this PC. It answers only widgets on this PC and never opens anything to the internet. Why: Reads today's and this week's cache savings for the chart. Swipe between Edge pages even when your finger starts on this widget. iCUE alone only swipes from the gaps between widgets.
Open links iCUE URL plugin
Opens a link or an app when you tap. Why: Starts the helper app if it is not running, so the widget fixes itself.
