Strict Header Self-Containment

Every header file (.h) in Filament must be fully self-contained and compile independently.

  • Rule: Never assume a header's type dependencies (like FrameGraphHandle) are pre-declared by preceding includes in a .cpp file.
  • Action: Always explicitly #include the declaring header (e.g., fg/FrameGraphId.h) inside the header itself.

How to use it

Copy the folder

Take google/header-self-containment from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
