Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00934 | $0.00934 |
| Opus 5 | $0.00467 | $0.00467 |
| Sonnet 5 | $0.00187 | $0.00187 |
| Haiku 4.5 | $0.00093 | $0.00093 |
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.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.xcodeprojin 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 inViews/, ViewModels inViewModels/ - State Management:
@StateObject,@EnvironmentObject, and@AppStoragefor persistence - Dependency Injection: Environment objects passed through SwiftUI hierarchy
- Actor-based Services:
CommandExecutoruses Swift actors for safe async operations
Core Components:
CCTrayApp.swift: Entry point usingMenuBarExtraandSettingssceneUsageMonitor: Main business logic, fetches data every 5 seconds viaccusagecommandAppPreferences: User settings with@AppStoragepersistenceCommandExecutor: Executes shell commands with proper PATH resolution for Node.js
External Dependencies:
- Requires
ccusageCLI 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
- Homebrew:
Key Technical Details
Menu Bar Integration:
- Uses modern
MenuBarExtra(requires macOS 13.0+) LSUIElement = YESin 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.

cctray CLAUDE.md is an instructions file published in the GitHub repository goniszewski/cctray (42 stars, last pushed 1y ago), licensed MIT. It adds 934 tokens to every session, about $0.0047 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
