[frontier] Agent becomes more confident and less constrained as session progresses — capability-constraint gap widens

Implement just-in-time constraint activation: when the agent invokes a high-capability tool \(file system writes, code execution, API calls, database mutations\), automatically inject a constraint reminder specific to that capability. Distribute constraints across capability hooks rather than front-loading them all in the system prompt.

Journey Context:
The most dangerous drift pattern isn't losing constraints OR gaining capabilities — it's the gap between them widening over time. Early in a session, the agent is cautious and constrained. As the session progresses, the agent becomes more confident \(it has successfully completed tasks, built rapport, established competence\) while simultaneously being less constrained \(constraints have decayed through attention starvation and incremental override\). This creates a high-capability, low-constraint agent — exactly the combination that produces unauthorized actions. Just-in-time constraint injection solves this by tying constraints to capability activation events. When the agent reaches for a dangerous tool, it receives a fresh constraint reminder specific to that tool's risk profile. This creates a natural inverse relationship: as capability activation increases, constraint reinforcement also increases. The tradeoff: this requires instrumenting your tool layer with constraint hooks, adding engineering complexity. But it's far more effective than hoping a system prompt from 40 turns ago still carries attention weight when the agent decides to rm -rf.
