Workflow Lite-Plan

Unified lightweight planning and execution skill. Routes to lite-plan (planning pipeline) or lite-execute (execution engine) based on trigger, with prompt enhancement for both modes.

Compact Recovery (Phase Persistence)

Multi-phase execution (lite-plan → lite-execute) spans long conversations that trigger context compression. Uses 双重保险: TodoWrite 跟踪 active phase 保护其不被压缩，sentinel 作为兜底。

⚠️ COMPACT DIRECTIVE: Context compression MUST check TodoWrite phase status. The phase currently marked in_progress is the active execution phase — preserve its FULL content. Only compress phases marked completed or pending.

Mode Detection & Routing

const args = $ARGUMENTS
const mode = detectMode()

function detectMode() {
  if (skillName === 'workflow:lite-execute') return 'execute'
  return 'plan'  // default: workflow-lite-plan
}

Routing Table:

Interactive Preference Collection

Before dispatching, collect workflow preferences via AskUserQuestion:

// ★ 统一 auto mode 检测：-y/--yes 从 $ARGUMENTS 或 ccw 传播
const autoYes = /\b(-y|--yes)\b/.test($ARGUMENTS)

if (autoYes) {
  // 自动模式：跳过所有询问，使用默认值
  workflowPreferences = { autoYes: true, forceExplore: false }
} else if (mode === 'plan') {
  const prefResponse = AskUserQuestion({
    questions: [
      {
        question: "是否跳过所有确认步骤（自动模式）？",
        header: "Auto Mode",
        multiSelect: false,
        options: [
          { label: "Interactive (Recommended)", description: "交互模式，包含确认步骤" },
          { label: "Auto", description: "跳过所有确认，自动执行" }
        ]
      },
      {
        question: "是否强制执行代码探索阶段？",
        header: "Exploration",
        multiSelect: false,
        options: [
          { label: "Auto-detect (Recommended)", description: "智能判断是否需要探索" },
          { label: "Force explore", description: "强制执行代码探索" }
        ]
      }
    ]
  })
  workflowPreferences = {
    autoYes: prefResponse.autoMode === 'Auto',
    forceExplore: prefResponse.exploration === 'Force explore'
  }
} else if (mode !== 'plan') {
  // Execute mode (standalone, not in-memory)
  const prefResponse = AskUserQuestion({
    questions: [
      {
        question: "是否跳过所有确认步骤（自动模式）？",
        header: "Auto Mode",
        multiSelect: false,
        options: [
          { label: "Interactive (Recommended)", description: "交互模式，包含确认步骤" },
          { label: "Auto", description: "跳过所有确认，自动执行" }
        ]
      }
    ]
  })
  workflowPreferences = {
    autoYes: prefResponse.autoMode === 'Auto',
    forceExplore: false
  }
}

workflowPreferences is passed to phase execution as context variable, referenced as workflowPreferences.autoYes and workflowPreferences.forceExplore within phases.

Prompt Enhancement

After collecting preferences, enhance context and dispatch:

// Step 1: Load project context via ccw spec
Bash('ccw spec load --category planning')

// Step 2: Log available context
console.log('Project context loaded via: ccw spec load --category planning')

// Step 3: Dispatch to phase (workflowPreferences available as context)
if (mode === 'plan') {
  // Read phases/01-lite-plan.md and execute
} else {
  // Read phases/02-lite-execute.md and execute
}

Execution Flow

Plan Mode

1. Collect preferences via AskUserQuestion (autoYes, forceExplore)
2. Enhance prompt with project context availability
3. Read phases/01-lite-plan.md
4. Execute lite-plan pipeline (Phase 1-5 within the phase doc)
5. lite-plan Phase 5 directly reads and executes Phase 2 (lite-execute) with executionContext

Execute Mode

1. Collect preferences via AskUserQuestion (autoYes)
2. Enhance prompt with project context availability
3. Read phases/02-lite-execute.md
4. Execute lite-execute pipeline (input detection → execution → review)

Usage

Plan mode and execute mode are triggered by skill name routing (see Mode Detection). Workflow preferences (auto mode, force explore) are collected interactively via AskUserQuestion before dispatching to phases.

Plan mode: Task description provided as arguments → interactive preference collection → planning pipeline Execute mode: Task description, file path, or in-memory context → interactive preference collection → execution pipeline

Phase Reference Documents

Compact Rules:

1. TodoWrite in_progress → 保留完整内容，禁止压缩
2. TodoWrite completed → 可压缩为摘要
3. 🔄 sentinel fallback → Phase 2 包含 compact sentinel；若 compact 后仅存 sentinel 而无完整 Step 协议，必须立即 Read("phases/02-lite-execute.md") 恢复
