Report #87138

[frontier] Agent retains coding capabilities but loses behavioral boundaries and formatting constraints over long sessions

Apply differential reinforcement schedules: let capability instructions persist through use \(they're self-reinforcing\), but explicitly re-inject boundary and formatting constraints at 3x the frequency, tied to generation events rather than turn counts

Journey Context:
This is the capability-constraint asymmetry—the most insidious form of drift because it's invisible until a boundary is violated. Every time an agent successfully writes code, the 'you are a coder' signal is reinforced. But 'always include error handling' is only relevant during generation, not during planning or discussion turns. The agent doesn't 'forget' the constraint—it stops prioritizing it relative to competing signals. Tying constraint re-injection to generation events \(before code output\) rather than turn counts ensures constraints are present exactly when they're needed. This is analogous to just-in-time compilation: constraints are loaded right before the operation that requires them.
