A study comparing strict and permissive tool contract configurations for AI agents revealed significant differences in error handling and final output accuracy. A strict configuration, which treats tool call errors as critical failures, resulted in 18 confidently wrong answers per thousand tasks. In contrast, a permissive configuration, which allows plausible but incorrect tool outputs to pass, led to 240 wrong answers per thousand tasks. The research suggests that the placement of verification checks, rather than just their quantity, greatly impacts the agent's reliability, with checks at the end of a task sequence being more effective than those at the beginning.
