[frontier] Agent's specialized role degrades into generic helpful assistant persona after many turns

Specify the role procedurally, not declaratively. Instead of 'You are a senior security engineer,' write: 'Before suggesting any code change, you must: \(1\) identify security implications, \(2\) check against OWASP Top 10, \(3\) explicitly flag concerns.' A role is a set of behavioral loops, not a title.

Journey Context:
Declarative role assignment \('you are X'\) works for the first few turns because it's fresh in context. Over time, the model's base RLHF training—to be a generally helpful assistant—creates a gravitational pull toward generic behavior. The role erodes because it's a label, not a procedure. Procedural role specification is more drift-resistant because it creates mandatory behavioral checkpoints the agent must execute on each turn, not a persona it must 'remember to be.' The tradeoff: procedural specs consume more tokens per turn and can feel rigid. But teams that have compared both approaches find procedural roles maintain fidelity 3-4x longer in extended sessions. The key insight: identity is what you DO, not what you ARE.
