Action button hierarchy problem

At the moment do not exist clearly defined action ** button hierarchy and easy to follow usage guide lines for developers and designers. This affects product usability and product development.

Description:
The action button hierarchy in the UI is important because it helps users quickly understand which action is primary, which is secondary, and which is less critical, thereby reducing hesitation and mistakes. A clear hierarchy guides attention, prevents accidental destructive actions, and supports efficient decision-making by matching visual weight (color, size, placement) with the importance of the action. In short, it improves clarity, safety, and efficiency in user interactions.

Expected:
Clearly defined action button hierarchy with easy to follow usage guide lines.
