Engineers warn Claude Managed Agents can fail after long iterative runs due to attention‑budgeting limit

- Anthropic engineers say Claude Managed Agents can fail after many iterative steps because the model's internal "attention budgeting" deprioritizes long, repeated context work. (x.com) - Developers traced repeated agent breakdowns to dropped context and forgotten tasks during prolonged sessions and many sub-agent handoffs. (x.com) (x.com) - That pattern is why builders are adopting external memory stores and manual context stitching to stabilize multi-step automation. (x.com)
