[frontier] System prompt constraints get overridden by conversation momentum in long sessions

Embed lightweight constraint reminders inside tool result payloads. When an agent calls a tool, include a 'compliance\_reminder' or 'system\_note' field in the response JSON that re-states 1-2 critical constraints. The agent must parse tool results to continue its task, giving these reminders higher effective attention than repeated system messages.

Journey Context:
Standard re-injection through system messages has diminishing returns because the agent learns to gloss over repeated instructions—a form of habituation where the model categorizes repeated text as boilerplate. But tool results occupy a different cognitive slot: the agent must parse and act on them to continue its task, giving them higher effective attention weight. This is the 'ghost nudge' pattern—constraints that travel disguised as operational data. Production teams are adding compliance\_metadata fields to their tool response schemas. The tradeoff is coupling your constraint system to your tool interface, but the benefit is constraints processed with fresh attention at every tool call \(typically every 3-5 turns in an agentic loop\). The critical mistake is making the reminder too long—if it exceeds 1-2 sentences, it becomes noise the agent learns to skip just like system prompt repetitions. Keep it terse and rotate which constraints you highlight.
