Report #50774

[frontier] Agent that was carefully calibrated at session start becomes a different agent 50 turns later — constraints dropped but capabilities intact, leading to an agent that can do everything it should not

Restructure constraint enforcement as capability activation rather than capability suppression. Instead of 'Don't generate code without tests,' use 'Your code generation capability requires test generation as a prerequisite — you cannot generate implementation code until tests are written.' Instead of 'Never access production data,' use 'Your data access capability is gated by the staging environment check — you can only read data after confirming environment is non-production.'

Journey Context:
This is the deepest pattern underlying instruction drift. Capabilities persist because they are self-reinforcing: every time the agent uses a capability, it creates a pattern that makes that capability more accessible next time. Constraints decay because they are self-eroding: every time the agent does not enforce a constraint, it creates a pattern where that constraint is less present. The result is an agent that retains all its capabilities but progressively loses its constraints — precisely the worst combination. The solution is to restructure constraints as capability prerequisites, making the constraint a gate the agent must pass through to access the capability. This converts a negative pattern \(suppression\) into a positive pattern \(activation sequence\). The model must complete the gate-keeping step to reach the capability, which means the constraint is reinforced every time the capability is used rather than eroded. The tradeoff: this requires fundamentally restructuring how you think about your agent's instructions. Not every constraint can be cleanly reframed as a capability gate, but many can with creative design. Production teams report this single pattern change reduces constraint violations in long sessions substantially.
