What is ccseva CLAUDE.md?

Project instructions for CCSeva, a macOS menu-bar app that monitors Claude Code usage and displays token data, analytics, notifications, and charts. The app uses Electron, React, TypeScript, and a command-line tool called ccusage.

Running the app during development, building frontend and production versions, checking code quality, creating macOS distributions, and working on its usage dashboard.

They explain the commands and structure needed to develop, test, lint, format, and package the app, reducing setup mistakes in a multi-part desktop project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03747	$0.03747
Opus 5	$0.01873	$0.01873
Sonnet 5	$0.00749	$0.00749
Haiku 4.5	$0.00375	$0.00375

Security

Grade A, and why

ccseva CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

CCSeva is a macOS menu bar Electron application that monitors Claude Code usage in real-time. The app spawns the ccusage CLI (v20+, a native Rust binary shipped via npm) with --json output to fetch token usage data and displays it through a modern React-based UI with tabbed navigation, analytics, notifications, and visualizations.

Essential Commands

Development

npm run electron-dev  # Start with hot reload (recommended for development)
npm run dev           # Build frontend only in watch mode
npm start            # Start built app

Building

npm run build        # Production build (webpack + tsc compilation)
npm run pack         # Package app with electron-builder
npm run dist         # Build and create distribution package
npm run dist:mac     # Build for macOS specifically

Code Quality

npm run lint         # Run Biome linter
npm run lint:fix     # Fix linting issues automatically
npm run format       # Format code with Biome
npm run format:check # Check code formatting
npm run check        # Run linting and formatting checks
npm run check:fix    # Fix linting and formatting issues
npm run type-check   # TypeScript type checking without emit

Dependencies

npm install          # Install all dependencies

Architecture Overview

Dual-Process Electron Architecture

The app follows standard Electron patterns with clear separation:

Main Process (main.ts): Manages system tray, IPC, and background services
Renderer Process (src/): React app handling UI and user interactions
Preload Script (preload.ts): Secure bridge exposing electronAPI to renderer

Key Architectural Components

Service Layer (Singleton Pattern)

CCUsageService: Spawns the ccusage CLI (native binary resolved from the @ccusage/ccusage-<platform>-<arch> optional dependencies) and parses its --json output, implementing a 3-second cache for stats and a 60-second cache for weekly data. Supports plan configuration and actual session-based reset times.
SettingsService: Manages user preferences persistence to ~/.ccseva/settings.json including plan selection, custom token limits, timezone, and reset hour settings
NotificationService: Manages macOS notifications with cooldown periods and threshold detection
ResetTimeService: Handles Claude usage reset time calculations and timezone management
SessionTracker: Tracks user sessions and activity patterns for analytics

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
