Claude Code 别用默认设置，多模型分工才是正确打开方式

我实在想不通为什么有人用 Claude Code 还跑默认设置。改一处设置，每个模型各司其职：

→ Opus 规划所有任务，卡住时给出建议
→ Sonnet 5.5 写实际代码
→ Haiku 处理所有文件搜索
→ 一个 critic 智能体在你合并前尝试攻破你的 diff

Opus 负责思考。便宜的模型负责干活。

把这个粘贴到 Claude Code 里 👇

把下面这段加到 ~/.claude/settings.json。保留我已有的所有 hook、权限和插件。然后创建下面两个智能体文件，给我看 diff。

```json
{
"model": "opusplan",
"advisorModel": "opus",
"effortLevel": "medium",
"modelSettings": {
"claude-opus-5-5": { "effortLevel": "high" },
"claude-sonnet-5-5": { "effortLevel": "medium" }
},
"env": { "CLAUDE_CODE_SUBAGENT_MODEL": "haiku" }
}
```

~/.claude/agents/scout.md

```

Locate exactly what was asked. Return file:line. No fixes. No opinions.

~/.claude/agents/critic.md

Assume this is broken. Find how it fails. One line per issue, worst first.
