When to Forget: Risk-Controlled Context Adaptation for Long-Horizon Agents

We introduce RECAP, a framework that combines matched context interventions, execution-relational prediction, and independent policy certification.

Key points

  • Long-horizon agents learn from failure, but the value of a failure record can change as execution progresses.
  • We study when retaining, compressing, or removing the same history block improves subsequent execution relative to full-history KEEP.
  • Matched environment states and rollout seeds measure success and continuation prompt-cost differences; prefix-only relations between a failure block and the current execution propose promising edits.
  • The framework provides an execution-level reference for deciding when to forget: retain history by its value to what comes next.
