Individual skill
msvc-cl
Use when building C or C++ on Windows with cl.exe or clang-cl: GCC-to-MSVC flag translation, /MT versus /MD, PDB output, or an LNK error. Not for MinGW cross builds from Linux: use cross-gcc.

# MSVC cl.exe and clang-cl
## Contract
| Field | Bound contract |
|---|---|
| Trigger | The user compiles on Windows with `cl.exe` or `clang-cl`, needs the MSVC spelling of a GCC flag, must pick a runtime library, wants PDB files, or has an `LNK` error. |
| Authority | Read-only. The skill emits flags, commands, and CMake settings to chat; the user runs them. Rollback is not needed. No remote mutation. |
| Side effect | Chat output. |
| Done | The flag set, runtime choice, and debug-info settings are reported, every flag is confirmed against the Microsoft compiler-options reference or `clang-cl /?`, and every `LNK` code in the request has a cause and fix. |
## Inputs
- Compiler: required. `cl.exe` from a Visual Studio install, or `clang-cl` from an LLVM release or the Visual Studio LLVM component. Current upstream Clang is 23.1.0.
