Opus 5 Agents Pay a Steep Rediscovery Cost: 475K Tokens Is the Record, Not the Bug
Sauers_ · x · 2026-10-28
A discussion on Opus 5 coding agents: when an agent instance is replaced, the new one inherits nothing the dead one learned — repo map, constraints, all gone — so one bad figure forces the replacement to pay the discovery cost again. The 475K token spend is the record, not the defect. The quoted author built a tool called memoryrouter to address this cross-instance memory gap.
