qt-cpp SKILL.md skillA
qt-cpp from codeatcode/oss-ai-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add codeatcode/oss-ai-skills/qt-cpp@v2.0.0Pins v2.0.0 in mdr.lock. Pin the fingerprint instead.

Use when developing desktop applications with Qt in C++ - CMake setup, signals and slots, QThread and QtConcurrent, QML integration, model/view programming, Qt5 to Qt6 migration, or windeployqt/macdeployqt/linuxdeployqt deployment.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Objective:** Use this skill to reduce segfaults from raw pointers, signal/slot connection failures, memory leaks from parentless QObjects, and thread-assertion violations by enforcing ownership rules, connection patterns, and RAII discipline below. # Qt C++ Development Complete reference for building cross-platform desktop applications with Qt framework in C++. ## Overview Qt is a powerful C++ framework for cross-platform application development. It provides rich GUI capabilities, networking, database access, and more. **Key Characteristics:** - Cross-platform (Windows, macOS, Linux, mobile) - Rich widget library and QML for modern UIs - Signal-slot mechanism for event handling - Meta-Object System (MOC) for reflection - Comprehensive documentation and examples ## Qt Versions ### Qt5 vs Qt6 | Feature | Qt5 | Qt6 | |---------|-----|-----| | C++ Standard | C++11 | C++17 minimum | | Graphics | OpenGL | Vulkan/Metal/DirectX | | High-DPI | Manual | Enabled by default | | QString | UTF-16 | UTF-8 by default | | Status | Maintenance | Active development | **Use Qt 6 for:** New projects, modern C++17/20 features, better graphics performance …

How to install
mdr add codeatcode/oss-ai-skills/qt-cpp@sha256:6cd7cc383d2e8615The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
