Individual skill
cpp-modules
Use when a C++ project adopts C++20 modules: named modules, partitions, header units, the global module fragment, CMake CXX_MODULES, or a BMI lookup error. Not for flag basics: use clang.

# C++20 modules
## Contract
| Field | Bound contract |
|---|---|
| Trigger | The user writes or builds `export module` code, asks how named modules differ from header units, needs the CMake wiring for module interface units, or gets a module-not-found, redefinition, or stale-BMI error. |
| Authority | Read-only. The skill emits module source shapes, compiler invocations, and CMake snippets to chat; the user applies them. Rollback is not needed. No remote mutation. |
| Side effect | Chat output. Any scratch build to confirm a flag runs on scratch files. |
| Done | The module layout, the per-compiler build commands, and the CMake wiring are reported for the user's compiler and CMake version, and every error in the request maps to a cause and fix. |
## Inputs
- Compiler and version: required. Clang 23.1.0 and GCC 16.2 are current stable; both accept the commands below.
