Claude Managed Agents 'Dreaming': Agents Review Past Sessions to Self-Improve — Detects Recurring Errors Across Dozens of Sessions You'd Never Spot

Anthropic·high signal

Anthropic shipped Dreaming as a research preview at Code with Claude (May 6). The feature lets agents review historical sessions, detect cross-session patterns like repeated classification errors, and write targeted memory updates. A customer support agent in session 47 doesn't know it made the same error 12 times — Dreaming reads across all sessions and fixes it. Available via managed-agents-2026-04-01 beta header.
