3. Tool and Interface Errors “Multi-tool workflows introduce fragile integration points.” When agents operate independently across multiple applications, reduced human oversight becomes the primary vulnerability, enabling unintended file manipulation and unauthorized transactions. State drift is a related problem: an agent loses track of what it has already done and calls the same API three times, or skips a critical step because it incorrectly believes the task is complete.
