 - `ID()` - Returns a unique identifier for this task
-- `Execute()` - Performs the task's operation, returning any errors
+- `Execute(ctx context.Context)` - Performs the task's operation with context, returning any errors
 - `Dependencies()` - Returns a list of task IDs that must complete successfully before this task can run
