usage-pet-light

Light-theme variant of usage-pet: a usage band above the prompt with Clawd, an animated pixel pet. For the Code tab of Claude Desktop.

Code you can checkTerminal + desktopBandToastBoxButtonSvg

What it does

  • Draws a band above the prompt, toasts
  • Adds /clawd
  • Hooks session.measure, session.start, turn.complete
  • Keeps its own state between turns
  • Starts processes

Good points

  • No network calls
  • Written in TypeScript
  • Has a desktop-specific branch
  • Handles errors

Code to start from

Two kinds: a starter modscode writes from the design above, and the lines of the mod's own code that draw it.

Starter (register.tsx)

register.tsx
import type { Register } from 'claude-code'

// Drawn like usage-pet-light by chinayuren2022-2025 (band, toast), as modscode read it from the mod's code:
// https://modscode.com/gallery/chinayuren2022-2025-usage-pet-light/
// Written by modscode from that reading, not copied from the mod: use it as you like.
// Each value below stands for one the mod works out at run time; put in your own.
export const register: Register = on => {
  // the band above the prompt; what else goes there is drawn under it
  on('ui.render', { component: 'AbovePrompt' }, async ($, e, next) => {
    const { Box, Svg, Button } = $.ui.resolve(e)
    const bandSvg = '…'
    const bandAlt = '…'
    return (
      <Box flexDirection="column">
        <Box flexDirection="row" alignItems="center">
          <Svg source={`${bandSvg}`} alt={`${bandAlt}`} height={30} isInteractive />
          <Button label="▲" plain />
        </Box>
        {await next(e)}
      </Box>
    )
  })

  on('session.start', async ($, e, next) => {
    const whatsNew = '…'
    const notes = '…'
    await $.ui.toast(`${whatsNew}${notes}`)
    return next(e)
  })
}

What its code shows

Read from the source at commit a6c47716f342 on 2026-10-06. The first group decides whether a mod is listed; the rest is for you to weigh. A later commit is not read until the next crawl.

This is a reading of the code text, not a security review: it does not run the mod, and it cannot see what a program the mod starts does. The check before installing is yours. How mods are chosen

Install it

Check it yourself before you install it. Mods run unsandboxed, with your permissions, and modscode does not vouch for what this code does. Read the code below (or run claude plugin validate . in its folder), weigh what it reaches, and install the commit you read.

Its repository is its marketplace. Add that marketplace (in the terminal with these commands, or in the desktop app's plugin settings) and install the mod from it:

/plugin marketplace add chinayuren2022-2025/claude-desktop-mods-light
/plugin install usage-pet-light@claude-desktop-mods-light

This installs the marketplace's latest commit, which may not be the one read here (a6c47716f342). Compare them before you install.

Ask Claude about it

With the modscode connector added, Claude can read this design, what its code reaches and its code, and build on them. Ask it like this:

Read the modscode design "chinayuren2022-2025-usage-pet-light" with its code and make me a pane like it
