# 预测建模 Skill

## Quick Start
1. Save as `~/.claude/skills/forecast-skill/SKILL.md`
2. Restart Claude Code
3. Type `/forecast-skill` or describe your task naturally
4. Claude auto-triggers when your task matches the description

## Instructions
- Understand the user's specific context and needs
- Apply domain best practices consistently
- Provide actionable, specific guidance with examples
- Verify all outputs before presenting to user

## Gotchas
- Test with a fresh Claude instance after changes
- Keep SKILL.md under 500 lines; use references/ for details
- Description is the trigger key — make it specific and keyword-rich

🚀 怎么用

1. 复制上面的 SKILL.md 代码
2. 保存为 ~/.claude/skills/forecast-skill/SKILL.md
3. 重启 Claude Code
4. 输入 /forecast-skill 或直接描述任务触发
5. AI 自动按 Skill 流程执行

三步预测

1) 数据探索：趋势+季节性+周期性+异常点。2) 模型选择：ARIMA（稳定数据）、Prophet（有季节性和节假日）、ETS（指数平滑）。自动对比，选误差最小的。3) 输出：预测值+置信区间+模型解释。一句话就能运行预测。
