Does this skill support Windows builds?

The skill provides platform notes for Windows, though it primarily automates the 'configure' and 'make' workflow used on Linux and macOS. For Windows, it will guide you through the Visual Studio requirements.

Can I use pytest with the CPython Build skill?

No, the CPython core project uses its own unittest-based regression suite. This skill is specifically designed to use 'python -m test' as required by CPython standards.

Why does the skill insist on building in a subdirectory?

Building in a 'build/' subdirectory (out-of-tree build) is a CPython best practice that keeps the source tree clean and allows for multiple configuration types (like debug and release) to coexist.

How do I speed up my CPython builds using this skill?

The skill automatically detects and configures 'ccache' if available. It also uses parallel execution via 'make -j' and provides instructions for installing ccache on various platforms.

Streamlines the process of compiling CPython from source, managing Argument Clinic, and executing the internal regression test suite.

The CPython Build & Test skill is a specialized tool for developers contributing to or debugging the Python interpreter. It automates complex workflows including out-of-tree build configuration, ccache integration for faster recompilation, and the regeneration of Argument Clinic files. By enforcing CPython-specific best practices—such as using the internal unittest runner instead of pytest and managing platform-specific build nuances—it ensures that changes to the CPython codebase are correctly compiled, verified, and benchmarked without common configuration errors.
