cctray CLAUDE.md

cctray CLAUDE.md is an instructions file for coding agents from goniszewski/cctray. It costs 934 tokens per session, scanned A, original, MIT.

Project instructions for CCTray, a macOS menu-bar app that monitors Claude Code usage through the ccusage command. They describe how to build, test, run, and structure the SwiftUI application.

In plain words
What is it for?
Use them when developing CCTray, opening or building it in Xcode, running its tests, or changing its usage-monitoring components.
Why use it?
They provide the repository-specific commands and design conventions needed to change the app safely. They also explain where models, views, view models, and services belong.

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.

Security

Grade A, and why

cctray 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 3d 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.

Build and Development Commands

Building the app:

# Open in Xcode and build with Cmd+B, or use command line:
xcodebuild -project CCTray.xcodeproj -scheme CCTray -configuration Debug

Running tests:

# Unit tests
xcodebuild test -project CCTray.xcodeproj -scheme CCTray -destination 'platform=macOS'

# In Xcode: Cmd+U for all tests

Running the app:

  • Open CCTray.xcodeproj in Xcode and press Cmd+R
  • App appears as orange "C" icon in macOS menu bar (no dock icon)

Architecture Overview

CCTray is a macOS menu bar application that monitors Claude Code usage through the ccusage CLI command. Built with SwiftUI using modern menu bar patterns.

Key Architecture Patterns:

  • MVVM: Models in Models/, Views in Views/, ViewModels in ViewModels/
  • State Management: @StateObject, @EnvironmentObject, and @AppStorage for persistence
  • Dependency Injection: Environment objects passed through SwiftUI hierarchy
  • Actor-based Services: CommandExecutor uses Swift actors for safe async operations

Core Components:

  • CCTrayApp.swift: Entry point using MenuBarExtra and Settings scene
  • UsageMonitor: Main business logic, fetches data every 5 seconds via ccusage command
  • AppPreferences: User settings with @AppStorage persistence
  • CommandExecutor: Executes shell commands with proper PATH resolution for Node.js

External Dependencies:

  • Requires ccusage CLI tool (Node.js based)
  • Default path: ~/.nvm/versions/node/v20.11.0/lib/node_modules/ccusage/dist/index.js
  • Node.js Detection: Automatically searches common installation paths:
    • Homebrew: /opt/homebrew/bin/node
    • System: /usr/local/bin/node, /usr/bin/node
    • nvm: ~/.nvm/versions/node/*/bin/node
    • Also checks current PATH environment variable

Key Technical Details

Menu Bar Integration:

  • Uses modern MenuBarExtra (requires macOS 13.0+)
  • LSUIElement = YES in Info.plist (menu bar only, no dock icon)
  • Custom orange "C" icon generated programmatically in IconCreator.swift

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.
