README

@muzi3/compaction-custom-model

Pi 扩展：让会话压缩（compaction）使用你指定的自定义模型，支持回退链（fallback）与可选思考等级。

安装

pi install npm:@muzi3/compaction-custom-model

配置

在 settings.json 中配置 compactionModel（全局 ~/.pi/agent/settings.json，或受信任项目的 .pi/settings.json）：

{
  "compactionModel": {
    "enabled": true,
    "model": "oneapi/Claude Haiku 4.5",
    "fallbackModels": ["oneapi/GPT-4o-mini"],
    "thinkingLevel": "low"
  }
}

字段	类型	说明
`enabled`	boolean	是否启用（默认 true）
`model`	string	主模型，`provider/modelId` 或纯 modelId
`fallbackModels`	string[]	主模型失败时依次尝试的回退模型
`thinkingLevel`	string	可选，压缩时的思考等级

行为

在 session_before_compact 阶段拦截压缩流程
依次尝试主模型与回退模型，逐个解析模型、校验鉴权、执行压缩
成功后通知「Compacted with /」；全部失败则告警并回退到 pi 默认压缩
