Qt has released a CMake Skill for AI coding agents that embeds authoritative Qt 6 CMake best-practice knowledge into agent reasoning contexts. The skill addresses a common problem where LLMs generate outdated Qt 5 patterns or incorrect CMake configurations when setting up Qt projects. It covers correct Qt 6 command usage, proper project scaffolding, QML module integration, and migration of legacy patterns. It performs a pre-flight check for common mistakes before producing output, and can consult live Qt documentation for exact command signatures. The skill works with Qt 6.5+ projects and has been tested with Claude Code CLI and GitHub Copilot using Claude Sonnet 4.6 and GPT-5.3 Codex. It is available on GitHub and the Claude marketplace as part of the qt-development plugin.
