The 'msbuild' script uses a PowerShell command with escaped quotes that attempts to locate MSBuild.exe. However, this script will fail if Visual Studio is not installed or if it's installed in a non-standard location. Consider adding error handling to check if vswhere.exe exists and if MSBuild is found. Additionally, the script uses a PowerShell variable interpolation that might not work correctly when invoked through npm due to quote escaping. The use of double backslashes in the path may also cause issues. Consider simplifying this or adding validation.

The build scripts have been completely reorganized from node-gyp based commands to MSBuild based commands. The old 'build' script ran 'node-gyp rebuild', but now runs 'npm run build:debug:x64'. This is a breaking change for users following the documentation in docs/Building.md which references 'npm run build', 'npm run build:x64', 'npm run build:x86', 'npm run build:arm64', and 'npm run build:all'. These scripts no longer work as documented - they now invoke MSBuild instead of node-gyp and have different behavior. The old node-gyp scripts have been renamed to 'gyp:build', 'gyp:build:x64', etc. The documentation needs to be updated to reflect these changes, or the script names should be kept backward compatible.

The installer process exit code is captured in $proc but never checked. If the installer exits non-zero (or partially installs), the subsequent path check may not provide a clear failure reason. Consider validating $proc.ExitCode and surfacing the last lines of the log when it fails.

The installer process exit code is captured in $proc but not checked. Consider validating $proc.ExitCode and failing with a clearer message/log snippet when the install fails.

clean runs msbuild /t:Clean without specifying Configuration/Platform, so it will only clean the solution default and may leave other outputs behind (especially after building multiple platforms). Consider adding configuration/platform-specific clean scripts (or a clean:all that iterates the supported matrix).

CI explicitly skips ANSI builds for ARM64/ARM64EC, but the npm scripts expose build:*:ansi:arm64* and include them in build:all:arm64 / build:all:arm64ec. Either remove these scripts (if ANSI isn’t supported for ARM64/ARM64EC) or add CI coverage so they don’t silently bit-rot.

Installing clang-format-17 via apt-get on ubuntu-latest is not stable because the available package versions change as the runner image updates. To avoid formatting CI breaking when the package isn’t available, consider using the previously used clang-format action, pinning an Ubuntu version, or adding the LLVM apt repository for the desired clang-format version.

This SDK install step pins a SHA256 for a fwlink URL. fwlink targets can change over time (even for the same SDK version), which would cause spurious CI failures when the hash no longer matches. Prefer using a stable/package-based install method (e.g., VS workloads/components on the runner, winget, or a versioned direct download URL you control) or making the hash/version pair configurable.

This SDK install step pins a SHA256 for a fwlink URL. fwlink targets can change over time, which risks random CI failures when the binary hash changes. Prefer installing via a stable package/component mechanism (or a stable, versioned direct download URL) rather than a mutable fwlink.
