An information processing device includes: a communication interface that receives instructions including a command to control an instrument; a storage that stores a rule of an execution procedure of the command; a CPU that verifies the instructions; and an output interface that outputs a verification result of the instructions. The CPU acquires the instructions through the communication interface, reads the rule from the storage, and detects a defect of the instructions by comparing an execution procedure of the command included in the instructions with the rule. The output interface outputs a detection result of the defect.
