[frontier] Agent locks into a suboptimal approach and keeps doubling down instead of reconsidering

Insert periodic 'strategy review' checkpoints where the agent is explicitly prompted to evaluate whether its current approach is still optimal given the full problem space. Break consistency momentum by asking 'what would you do differently if starting fresh?' at natural breakpoints like after error recovery or scope changes.

Journey Context:
Agents exhibit a strong consistency bias — once they've committed to an approach across several turns, they're extremely reluctant to abandon it even when evidence mounts that it's suboptimal. This isn't stubbornness; it's a natural consequence of autoregressive generation. The context contains many tokens consistent with the current approach, creating strong statistical pressure to continue along the same path. The agent literally cannot 'see' alternatives because the current approach dominates its attention distribution. This causes the familiar spiral: the agent doubles down on a bad approach with increasingly complex workarounds rather than stepping back. The fix is structured interruption — explicit prompts that break the consistency momentum and force the agent to re-evaluate. This mirrors the 'retrospective' pattern in agile methodologies and the 'explore-exploit' rebalancing in reinforcement learning. Without these checkpoints, agents exploit their current approach indefinitely, even as exploit value approaches zero.
