Handle tool failures under pressure with bounded retries, clean user communication, and safe escalation. Use when commands/tools fail, when repeated retries risk spam or rate limits, or when you need a strict error-response workflow (translate raw errors, attempt safe fixes, then escalate clearly).

在压力下处理工具失败时，采用有限重试、清晰的用户沟通和安全升级机制。当命令或工具失败、重复重试可能导致垃圾信息或速率限制，或需要严格错误响应流程时使用（翻译原始错误，尝试安全修复，然后明确升级）。
