model-fallback
模型自动降级与故障切换。当主模型请求失败、超时、达到速率限制或配额耗尽时，自动切换到备用模型，确保服务连续性。支持多供应商、多优先级的智能模型选择，提供健康监控、自动重试和错误恢复机制。
Best use case
model-fallback is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using model-fallback should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# 模型自动降级与故障切换 - Author: Daniel Li - Copyright © Daniel Li. All rights reserved. ## 当使用此技能 - 模型请求失败 - API 超时 - 达到速率限制 - 配额耗尽 - 需要确保服务连续性 ## 工作原理 1. **监控**: 检测模型请求状态 2. **判断**: 识别失败类型（超时/限额/错误） 3. **切换**: 自动降级到备用模型 4. **重试**: 失败请求自动重试 5. **恢复**: 主模型恢复后自动切回 ## 多供应商支持 - 优先级配置 - 跨供应商故障转移 - 智能负载均衡 ## 错误类型 - **超时**: 切换到更快模型 - **限额**: 切换到有配额模型 - **错误**: 切换到不同供应商 ## 触发词 - "模型降级" - "自动切换" - "模型故障" - "API 失败"
