Add it to any role that sends, books, charges, deletes or searches; it asks the agent to re-read the line that governs each of those steps right before taking it. The article cites Anthropic's review published September 9, 2026: in re-runs of one incident, a scope reminder stopped the behavior 90% of the time when it was the last thing in context, and 40% when it came three turns earlier; Anthropic suspects a "momentum effect". Anything that must never happen still needs a setting that blocks it.
