wavy-usage

Liquid-filled rings above the Claude Code prompt for the 5-hour and 7-day limit windows, context fill and prompt-cache lifetime, a fighter jet that shows the model's effort, and a pane of recent turns, their cost, their share of the 5-hour…

Code you can checkTerminal + desktopPaneBandToastBoxButtonSvgText

What it does

  • Draws a pane, a band above the prompt
  • Adds /wavy-usage
  • Hooks session.measure, session.start, turn.complete, turn.step and 1 more
  • Keeps its own state between turns

Good points

  • No network calls
  • Starts no processes
  • Written in TypeScript
  • Has a desktop-specific branch

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 wavy-usage by Batuhan Çakmak (pane, band, toast), as modscode read it from the mod's code:
// https://modscode.com/gallery/batuhancakmakk-wavy-usage/
// 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 pane: open it with $.ui.open({ id: 'my-pane', title: "‹paneTitle›" })
  on('ui.render', { component: 'Pane', requestId: 'my-pane' }, async ($, e) => {
    const { Box, Svg, Text, Button } = $.ui.resolve(e)

What its code calls

What its code shows

Read from the source at commit 747a9806e7e3 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 readEvery module hooks/hooks.json names was read.hooks/register.tsx
ParsesEvery file parses as TypeScript or JavaScript.6 files parsed

Calls in the openNetwork 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

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 BatuhanCakmakk/wavy-usage
/plugin install wavy-usage@wavy-usage

This installs the marketplace's latest commit, which may not be the one read here (747a9806e7e3). 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 "batuhancakmakk-wavy-usage" with its code and make me a pane like it

Search them from Claude: the MCP connector
