[frontier] Re-injecting constraints mid-session is disruptive to conversation flow and feels robotic

Use 'shadow re-injection'—place constraint reminders in the agent's chain-of-thought or reasoning steps \(e.g., in or scratchpad blocks\) rather than in visible conversation turns. The agent attends to its own reasoning tokens with the same attention mechanism as external input, so reminders in CoT are just as effective as visible ones.

Journey Context:
The core tension in constraint maintenance is effectiveness vs. user experience. Visible re-injections \('As a reminder, I must follow rule X...'\) break conversation flow and feel unprofessional. Shadow re-injection leverages the fact that models with chain-of-thought or extended thinking attend to their own reasoning tokens identically to user tokens in the attention mechanism. By placing reminders in the reasoning stream, you get the attention reinforcement without the UX cost. This is particularly effective with models supporting extended thinking. The tradeoff: shadow re-injection only works with models that have a reasoning/scratchpad capability—it doesn't work with models that generate only visible output. Also, the reminder must be in the current turn's reasoning, not a past turn's.
