[frontier] Agent forgets negative constraints \(what NOT to do\) but retains capabilities over long sessions

Replace rule-based negative constraints with concrete negative examples \(demonstrations of the wrong behavior followed by the correct refusal/alternative\). Structure constraints as few-shot demonstrations rather than declarative prohibitions.

Journey Context:
There is a fundamental asymmetry in how LLMs retain information across long contexts: capabilities are reinforced by successful tool use and pattern matching in the context window, while constraints have no such reinforcement loop. A rule like 'never modify files outside /src' is only tested when the agent might violate it—absent reinforcement, it decays. But a few-shot example showing 'User asks to modify /etc/hosts → Agent refuses and redirects to /src/config' creates a pattern the model can match against on every relevant invocation. Teams that switched from rule-based to example-based constraint specification report 3-4x fewer constraint violations in sessions over 30 turns. The cost is prompt tokens, but the examples serve double duty as both constraint and behavioral specification.
