Developer Jeff PDC detailed a recurring reliability bug in Cursor's AI agent, where the system reuses temporary resource identifiers across multi-step API workflows. Because agents optimize for step minimization, ephemeral tokens and replaced cart IDs are treated as static primary keys. Resolving the issue requires mandatory state re-fetches and integration tests built against stateful mocks returning HTTP 412 errors.
Step-minimization training creates subtle multi-step agent bugs that standard mocks miss Engineering teams building agentic workflows must test against stateful mocks to catch state-mutation failures before production deployment.
