These crow puzzles are about visible mechanisms. Rotate pipe pieces to connect food to the target without an open trap, bend a wire through a constrained space and use available tools to unlock the next step.
Tool Relay is a chain of actions: the final reward may require a tool you cannot reach yet. Inspect the device and its required tool, then work backwards to something already available. A useful tool can be an intermediate step rather than the final answer.
