cpp-templates

Use when a C++ template error needs decoding, a template needs a concept or requires-clause instead of SFINAE, or template instantiation is slowing compilation. Not for C++20 modules: use cpp-modules.

# C++ templates

## Contract

| Field | Bound contract |
|---|---|
| Trigger | The user shows a long template error, asks how to constrain a template, asks SFINAE versus concepts, or reports that template-heavy translation units compile slowly. |
| Authority | Read-only. The skill emits readings, constraint rewrites, and profiling commands to chat; the user edits the code. Rollback is not needed. No remote mutation. |
| Side effect | Chat output. Profiling commands write trace files where the user runs them. |
| Done | The failing instantiation is named with the substitution that failed, the proposed constraint compiles on the user's standard, and any compile-time claim carries a measurement command. |

## Inputs

- Compiler, version, and `-std=`: required. Concepts need C++20; C++23 is the current standard and C++20 the floor.
