Report #68264

[frontier] Agent treats all instructions as equally important, causing unresolvable constraint conflicts in long sessions

Explicitly tier your constraints into three levels in the system prompt: Tier 1 / MUST \(inviolable — safety, legal, core identity\), Tier 2 / SHOULD \(strong preferences — style, format, approach\), Tier 3 / PREFER \(flexible guidelines — methodology, defaults\). Re-inject Tier 1 constraints at self-verification checkpoints. When constraints conflict, the model should defer to the higher tier.

Journey Context:
When all constraints are presented with equal urgency, the model has no principled way to resolve conflicts. In a long session, when a user request implicitly conflicts with a constraint, the model must choose — and without a hierarchy, it defaults to the most recent or most specific signal, which is usually the user's request. This is the root cause of much apparent 'drift': the agent has not forgotten the constraint, but it has encountered a conflict and resolved it in favor of recency. Making all constraints 'stronger' \(more emphatic language\) does not help — it just makes all constraints equally loud, which is the same as no hierarchy. The tiered pattern, borrowed from Constitutional AI's principle ordering, gives the model a decision framework. Tier 1 constraints are phrased with 'MUST' and are re-injected at checkpoints. Tier 2 uses 'SHOULD.' Tier 3 uses 'PREFER.' This is not just documentation — it measurably changes the model's conflict resolution behavior. Production teams report that explicit hierarchies reduce drift more effectively than making all constraints equally emphatic, because the model can now resolve conflicts without discarding constraints entirely.
