CmdManager: Instructions file for Claude Code

CLAUDE.md

CmdManager CLAUDE.md is an instructions file for Claude Code from minerd/CmdManager. It costs 1,978 tokens per session, scanned A, original, MIT.

Project instructions for CmdManager, a Windows desktop utility built with .NET that monitors and remotely controls open Command Prompt windows. It shows their status and preview, sends commands without taking focus, and stores folder history and favourites.

In plain words
What is it for?
Use them when building or running CmdManager, changing its WPF interface, localisation, console controls, command history, or integration with the external `cc` launcher.
Why use it?
They give an AI assistant the project’s architecture, build command, runtime details, and Windows-specific requirements. This reduces guesswork when changing or running the utility.

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

CmdManager 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 1mo 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

CmdManager is a WPF (.NET 8, x64-only) utility that monitors and remote-controls open cmd.exe windows on this machine. It lists cmd windows working on the E: or F: drives, shows a live colored preview of the selected console, indicates busy/idle state, sends commands to consoles without stealing focus, and keeps history/favorites of working directories. It is built around an external cc command assumed to be on PATH (the user's Claude Code launcher) — several actions open a cmd and run cc in it. The UI is localized (English default, Turkish toggle via the 🌐 button): XAML strings resolve through DynamicResource keys rebuilt by ApplyLanguage() from the UiStrings table, and code-behind strings use Loc.T(en, tr). The chosen language persists in settings.json (Language).

Build & Run

  • Build: dotnet build -c Release
  • Run: launch bin\Release\net8.0-windows\win-x64\CmdManager.exe. The manifest declares requireAdministrator (needed for ReadProcessMemory/AttachConsole on other processes), so every launch triggers UAC.
  • Publish single-file to publish/: dotnet publish -c Release -r win-x64 --self-contained false -p:PublishSingleFile=true -o publish
  • Regenerate the icon: powershell -File make_icon.ps1 (draws the >_ glyph programmatically and writes app.ico)
  • There are no tests and no linter config.
  • Gotcha: App.xaml sets ShutdownMode="OnExplicitShutdown" and nothing ever calls Application.Shutdown(), so closing the main window leaves the process running. A surviving instance locks the exe and makes the next build fail with a file-in-use error — kill CmdManager from Task Manager before rebuilding.

Architecture

All logic lives in two files:

  • Native.cs — every Win32 P/Invoke, exposed as static methods on Native (enumerate cmd windows, read another process's working directory, read/write another process's console, global hotkey, focus/keyboard helpers).
  • MainWindow.xaml.cs — all UI state and behavior: the CmdItem/HistoryItem/FavoriteItem models, the polling timers, persistence, and every event handler. InputDialog (a code-built prompt window) is at the bottom of the same file.

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.
