Review Comment:
`<condition_variable>`, the `Connection` forward declaration, and the `mutex_` member are unused in the current implementation (and there are no synchronized accesses shown). If thread-safety is not part of this class’ responsibility, remove these to keep the API minimal; otherwise, add the corresponding synchronized logic so the extra members/includes are justified.

Review Comment:
The callback takes `ClassDescription` by value while `ClassDescription` is only forward-declared in this header. Passing an incomplete type by value is a brittle API (and forces the full definition to be available at call sites). Prefer taking `const ClassDescription&` (or a pointer) to avoid copies and reduce header coupling.

Review Comment:
`MinifiControllerService*` is an opaque C handle type. Reinterpreting it as `ControllerServiceType*` is not type-safe and is very likely incorrect at runtime/ABI level (handle vs. implementation object). A safer design is to return the opaque handle (or a small C++ wrapper around it) and expose typed operations through explicit API functions, rather than casting the handle to the implementation type.

Review Comment:
This returns success whenever the callback sets `value`, even if `status` indicates an error. The C API already returns a `MinifiStatus`, so the wrapper should primarily check `status != MINIFI_STATUS_SUCCESS` (and only use `value` as the payload). Otherwise, any implementation that invokes the callback before returning a failure status could be incorrectly reported as success.

`std::string::contains` is a C++23 feature. If this project is built with C++20 (the rest of this hunk uses `std::ranges`, which is C++20), this line will not compile. Consider using `str.find(ending) != std::string::npos` or gating `contains` behind a feature-test / C++ standard check.

Review Comment:
Exceptions must not cross the C callback boundary. Two concrete issues here:\n1) `.create` can throw (e.g., `parse(...).value()` on invalid UUID, `new Class{...}` if the constructor throws), which would unwind through a C ABI callback.\n2) `.notifyStop` lacks a try/catch, so any exception thrown by the extension implementation will unwind through the C ABI.\nWrap both callbacks in `try/catch (...)` and return a safe failure signal (`nullptr` from `.create`; swallow/log in `.notifyStop` or report via an error channel if available). Also avoid `.value()` here; prefer an explicit failure path.

What is the purpose of this class? a description in a code comment would be helpful IMO

this will need to be fixed on rebase: `nonstd` -> `std`

Review Comment:
I think this is another thing that you'll fix during rebase without me commenting, but this should be `MinifiControllerService*` instead of `void*`.

Review Comment:
I know it doesn't matter, but it hurts my OCD that this kind of object is called a "description" everywhere, but the name of the class is "...Definition".
If it's not too much work to change it, it would be better if this was a "definition" everywhere or a "description" everywhere, including the class name.

Review Comment:
Why do we need this new version of `addController`? We only seem to be using the old version.

Review Comment:
agreed, i went with definition everywhere because the class already contains description so it made more sense for me
