Why ACE beats one-big-prompt automations
Complex automations often fail because one blob tries to do everything. The ACE framework separates responsibility into three layers so each piece can be designed, tested, and improved on its own:
- Aim defines the business intent in plain language.
- Coordinate decides who or what runs next and when.
- Execute performs the work via deterministic scripts and tools.
This separation echoes classic software guidance on modular design. If you have never read David Parnas on modularization, his landmark paper explains why clear interfaces and information hiding make systems easier to reason about and test, which is
