Use when working with C++20 co_await, co_yield, and co_return, implementing promise_type, sizing coroutine frames, or debugging suspended coroutines in GDB. Not for Rust async: use idiomatic-rust.

# C++20 coroutines

A coroutine is a function whose execution suspends and resumes while its frame survives on the heap. The language provides the keywords; the library author provides `promise_type`, which decides what suspension and return mean.

## Contract

| Field | Bound contract |
|---|---|
| Trigger | The task writes or reviews `co_await`, `co_yield`, or `co_return` code, implements a `promise_type`, explains the coroutine frame, or debugs a suspended coroutine. |
| Authority | Read-only. The skill explains mechanics and drafts coroutine types; edits land through the normal coding path. No remote mutation. |
| Side effect | None. |
| Done | The drafted coroutine type compiles against the project standard, or the coroutine under debug is located and its promise state read. |
