Use when building features, fixing bugs, or adding capabilities that need a verifiable definition of done. Use with a project's AC.md acceptance table when available; also use when the user says implement, add, fix, acceptance criteria, or done means.

Use when writing code, designing architecture, choosing dependencies, or implementing features — especially when the task involves technology or domains (C++, Qt, astronomy, desktop apps, image processing, scientific computing) where the author has prior project experience documented in the vault. Also use when the user mentions starting a new project or asks you to follow their coding style.
