Give Engine well defined tasks you might usually ask a junior or a mid level engineer to complete. This usually maps to the bottom 50% of issues in terms of complexity on a typical well-managed board.
The more tightly defined a task is, the better Engine will perform. To get Engine to help with bigger tasks, try splitting them into smaller, well defined issues - this also helps with code review!Examples of tasks Engine is a great fit for:
Simple bug fixes
UI updates
New API endpoints
Minor refactoring
Adding specific unit tests
Put Engine to work on all those backlog issues that never get done!
