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)
import type { Register } from 'claude-code'
// Drawn like usage-band by DoingSomethinh (band), as modscode read it from the mod's code:
// https://modscode.com/gallery/doingsomethinh-usage-band/
// 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 } = $.ui.resolve(e)
const limits = '…'
const limitsAlt = '…'
const io = '…'
const ioAlt = '…'
const value = '…'
const cost = '…'
return (
<Box flexDirection="column">
<Box flexDirection="row" flexWrap="nowrap" alignItems="center" width="100%">
<Box flexGrow={1} width={0} flexDirection="row" justifyContent="flex-start">
<Svg source={`${limits}`} alt={`${limitsAlt}`} />
</Box>
<Box flexShrink={0}>
<Svg source={`${io}`} alt={`${ioAlt}`} />
</Box>
<Box flexGrow={1} width={0} flexDirection="row" justifyContent="flex-end">
<Svg source={`${value}`} alt={`Session cost ${cost}`} />
</Box>
</Box>
{await next(e)}
</Box>
)
})
}

What its code shows
Read from the source at commit cebe37ffbfb2 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.
| Decides the listing: code you can check | |
|---|---|
| Entry read | Every module hooks/hooks.json names was read.hooks/register.tsx |
| Parses | Every file parses as TypeScript or JavaScript.1 files parsed |
| All its code is in the mod | Every import is a file of the mod or the engine's own module; no packages, no require.all its code is in the mod |
| Readable | No minified lines, no eval or new Function, no import of a computed path, no encoded blobs.no minified code, no eval, no encoded blobs |
| Calls in the open | Network and programs are reached as $.http.fetch and $.process.run in place, never passed around.every call outside goes through $ in the open |
| For you to weigh before installing | |
| Where it draws | The terminal, the desktop app, both, or nothing (hooks only: a guard or a prompt rewriter), as its code says. Shown, never a reason to leave a mod out.draws in the desktop app only |
| Install line | Whether its repository's own .claude-plugin/marketplace.json lists it, so it installs from that marketplace with the lines on its page.listed in its repository's .claude-plugin/marketplace.json: installs from there |
| Programs on Windows | Whether every program it starts through $.process exists on Windows (tail, date, open, osascript, /usr/… do not).runs no program a Windows PC lacks |
| Network | Whether every fetch names its https host in the code.no network |
| Programs | Whether every program it starts is named in the code and is not a shell, an interpreter or a network tool.starts no programs |
| Reads and sends | Whether it both reads files or environment variables and reaches the network.reaches no network |
| Keys in the source | Whether the source holds what looks like an API key or a private key.no keys in the source |
| Licence | An open licence (MIT, Apache-2.0, BSD, ISC, Unlicense, 0BSD, CC0) with its text lets modscode show its code; otherwise the code is linked.no licence |
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 DoingSomethinh/usage-band-marketplace/plugin install usage-band@usage-bandThis installs the marketplace's latest commit, which may not be the one read here (cebe37ffbfb2). Compare them before you install.
