Report #40544

[frontier] Agent carries over implicit assumptions, workarounds, or 'hacks' from previous sessions or earlier in the current session that are no longer valid, leading to compounding technical debt in generated code

Implement Explicit State Invalidation Barriers: insert a structured 'context reset' XML tag \(e.g., \) whenever the task phase changes; require the agent to explicitly list 3 assumptions it's dropping before proceeding past the barrier; maintain an 'active assumptions' scratchpad that gets wiped and rewritten at each barrier rather than accumulating

Journey Context:
Agents develop 'path dependency'—they solve subproblem A with workaround X, then when subproblem B comes up, they assume X is still valid even when context changed, leading to 'hack propagation' where temporary fixes become permanent architectural decisions. Simple summaries don't catch implicit assumptions because they're never explicitly stated. The barrier forces explicit invalidation, creating a 'psychological cost' to carrying forward assumptions. The '3 assumptions' requirement creates friction that prevents autopilot continuation. This pattern comes from observability research in multi-agent systems and reflexion-based agents where 'assumption tracking' became necessary for debugging long agent chains, and is being adopted by 2025 production coding agents to prevent 'dependency hell' in generated codebases.
