Agent-Controlled Forgetting for Tool-Using Agents (arXiv:2610.10590v1)
This arXiv preprint proposes 'agent-controlled forgetting', where an agent replaces prior tool outputs in its context with short notes while storing exact originals in a recoverable archive; a Python harness enables batch archival and explicit recovery without task-specific training. In an OpenTelemetry debugging case plus an unrelated implementation task the method reduced provider-reported prompt tokens to 231,951 from 912,492, halved cumulative input tokens and cut estimated API cost to roughly USD 1.28–1.44 vs ≈USD 4.38, but made more requests, ran ~17% slower, and showed workload-dependent effectiveness across other test pairs and continuations.
