AI coding agent struggles to follow rules despite memory and fixes

An AI developer measured the effectiveness of their coding agent's rule-following capabilities, finding that the agent repeatedly made the same mistake despite having explicit rules and memory of the error. The developer experimented with different methods of rule implementation, including loading rules at session start and on-demand retrieval, but found these insufficient to prevent the agent from ignoring them. The most effective solution involved changing the rules to require visible evidence of actions, such as specific commands or files read, which allowed for external checks to refuse non-compliant turns. AI

IMPACT Highlights the ongoing challenges in ensuring AI agents reliably adhere to instructions and memory, indicating a need for more robust control mechanisms.
