Proposed fix: [Claude Managed Agents budgets] 400 'budget.max_list_cost must be greater than the session's consumed list cost' and other budget rejections (decimal amount, add-after-create, unpriced m
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Set new max_list_cost strictly above usage.list_cost; send amounts as whole-cent strings ('2500'); attach budgets at create time only; remove budget for unpriced models.
Option: Base the new cap on consumed cost [evidence: official_recommended_action]
Applies when: Claude Managed Agents API / session budgets (max_list_cost)
Steps:
1. Read session usage.list_cost
2. Update max_list_cost to a larger whole-cent string
3. Settle pending tool events first if at cap
Expected: Request accepted / failure becomes diagnosable
