Report #63610

[frontier] Constraints are technically present in context but agent behaves as if they do not exist

Implement active constraint verification: before any substantive action, include a verification step that requires the agent to explicitly list applicable constraints and confirm compliance. Use structured output formats \(checklists\) rather than relying on implicit adherence.

Journey Context:
This is the 'ghost constraint' problem, distinct from constraints being absent. The constraint exists in the context window but receives near-zero attention weight because it's buried among thousands of tokens of implementation detail. It's related to the needle-in-a-haystack retrieval problem but worse: the agent doesn't even know it should be looking. Passive presence is insufficient. Active verification forces the attention mechanism to engage with constraints on every action. The tradeoff is increased token usage and slight latency, but production teams find this cost negligible compared to the cost of constraint violations in deployed agents.
