Brief Mode Command Skill

Brief模式命令 - Entitlement check + UserMsgOptIn同步 + MetaMessages。

功能概述

从Claude Code的brief.ts提取的brief模式，用于OpenClaw的精简输出控制。

核心机制

双Gate控制

isEnabled: () => {
  if (feature('KAIROS') || feature('KAIROS_BRIEF')) {
    return getBriefConfig().enable_slash_command
  }
  return false
}
// Feature flag + GrowthBook config双层控制

Entitlement Check

// on-transition需要entitlement
if (newState && !isBriefEntitled()) {
  logEvent('tengu_brief_mode_toggled', { enabled: false, gated: true })
  onDone('Brief tool is not enabled for your account')
  return null
}
// off-transition总是允许
// 防止用户卡住

UserMsgOptIn同步

setUserMsgOptIn(newState)
// userMsgOptIn tracks isBriefOnly
// 保证tool available exactly when mode on

MetaMessages注入

const metaMessages = [
  `<system-reminder>
    Brief mode enabled. Use BriefTool for output.
  </system-reminder>`
]
// 明确的transition信号
// 避免model inertia

实现建议

OpenClaw适配

1. dualGate: Feature + GB config
2. entitlement: 启用检查
3. sync: State + OptIn同步
4. metaMessages: 明确提示

状态文件示例

{
  "isBriefOnly": true,
  "userMsgOptIn": true,
  "entitled": true,
  "kairos": false
}

关键模式

Gated Transition

on: check entitlement
off: always allow
// 防止gate flip mid-session卡住用户

Tool-State Synchronization

setUserMsgOptIn(newState)  // Tool availability
setAppState({ isBriefOnly: newState })  // Mode state
// 两者同步避免tool list stale

MetaMessages for Clarity

<system-reminder> transition message
// 明确告知mode变化
// 避免模型继续用旧方式

借用价值

• ⭐⭐⭐⭐⭐ Entitlement check pattern
• ⭐⭐⭐⭐⭐ Tool-state synchronization
• ⭐⭐⭐⭐⭐ MetaMessages injection
• ⭐⭐⭐⭐ Dual gate control
