# Workflow Lite-Plan Command (/workflow:lite-plan)

## Overview

Intelligent lightweight planning command with dynamic workflow adaptation based on task complexity. Focuses on planning phases (exploration, clarification, planning, confirmation) and delegates execution to `/workflow:lite-execute`.

**Core capabilities:**
- Intelligent task analysis with automatic exploration detection
- Dynamic code exploration (cli-explore-agent) when codebase understanding needed
- Interactive clarification after exploration to gather missing information
- Adaptive planning strategy (direct Claude vs cli-lite-planning-agent) based on complexity
- Two-step confirmation: plan display → multi-dimensional input collection
- Execution dispatch with complete context handoff to lite-execute

## Usage

```bash
/workflow:lite-plan [FLAGS] <TASK_DESCRIPTION>

# Flags
-e, --explore              Force code exploration phase (overrides auto-detection)

# Arguments
<task-description>         Task description or path to .md file (required)
```

## Execution Process

```
Phase 1: Task Analysis & Exploration
   ├─ Parse input (description or .md file)
   ├─ intelligent complexity assessment (Low/Medium/High)
   ├─ Exploration decision (auto-detect or --explore flag)
   ├─ ⚠️ Context protection: If file reading ≥50k chars → force cli-explore-agent
   └─ Decision:
      ├─ needsExploration=true → Launch parallel cli-explore-agents (1-4 based on complexity)
      └─ needsExploration=false → Skip to Phase 2/3

Phase 2: Clarification (optional, multi-round)
   ├─ Aggregate clarification_needs from all exploration angles
   ├─ Deduplicate similar questions
   └─ Decision:
      ├─ Has clarifications → AskUserQuestion (max 4 questions per round, multiple rounds allowed)
      └─ No clarifications → Skip to Phase 3

Phase 3: Planning (NO CODE EXECUTION - planning only)
   └─ Decision (based on Phase 1 complexity):
      ├─ Low → Load schema: cat ~/.claude/workflows/cli-templates/schemas/plan-json-schema.json → Direct Claude planning (following schema) → plan.json → MUST proceed to Phase 4
      └─ Medium/High → cli-lite-planning-agent → plan.json → MUST proceed to Phase 4

Phase 4: Confirmation & Selection
   ├─ Display plan summary (tasks, complexity, estimated time)
   └─ AskUserQuestion:
      ├─ Confirm: Allow / Modify / Cancel
      ├─ Execution: Agent / Codex / Auto
      └─ Review: Gemini / Agent / Skip

Phase 5: Dispatch
   ├─ Build executionContext (plan + explorations + clarifications + selections)
   └─ SlashCommand("/workflow:lite-execute --in-memory")
```

## Implementation

### Phase 1: Intelligent Multi-Angle Exploration

**Session Setup** (MANDATORY - follow exactly):
```javascript
// Helper: Get UTC+8 (China Standard Time) ISO string
const getUtc8ISOString = () => new Date(Date.now() + 8 * 60 * 60 * 1000).toISOString()

const taskSlug = task_description.toLowerCase().replace(/[^a-z0-9]+/g, '-').substring(0, 40)
const dateStr = getUtc8ISOString().substring(0, 10)  // Format: 2025-11-29

const sessionId = `${taskSlug}-${dateStr}`  // e.g., "implement-jwt-refresh-2025-11-29"
const sessionFolder = `.workflow/.lite-plan/${sessionId}`

bash(`mkdir -p ${sessionFolder} && test -d ${sessionFolder} && echo "SUCCESS: ${sessionFolder}" || echo "FAILED: ${sessionFolder}"`)
```

**Exploration Decision Logic**:
```javascript
needsExploration = (
  flags.includes('--explore') || flags.includes('-e') ||
  task.mentions_specific_files ||
  task.requires_codebase_context ||
  task.needs_architecture_understanding ||
  task.modifies_existing_code
)

if (!needsExploration) {
  // Skip to Phase 2 (Clarification) or Phase 3 (Planning)
  proceed_to_next_phase()
}
```

**⚠️ Context Protection**: File reading ≥50k chars → force `needsExploration=true` (delegate to cli-explore-agent)

**Complexity Assessment** (Intelligent Analysis):
```javascript
// analyzes task complexity based on:
// - Scope: How many systems/modules are affected?
// - Depth: Surface change vs architectural impact?
// - Risk: Potential for breaking existing functionality?
// - Dependencies: How interconnected is the change?

const complexity = analyzeTaskComplexity(task_description)
// Returns: 'Low' | 'Medium' | 'High'
// Low: Single file, isolated change, minimal risk
// Medium: Multiple files, some dependencies, moderate risk
// High: Cross-module, architectural, high risk

// Angle assignment based on task type (orchestrator decides, not agent)
const ANGLE_PRESETS = {
  architecture: ['architecture', 'dependencies', 'modularity', 'integration-points'],
  security: ['security', 'auth-patterns', 'dataflow', 'validation'],
  performance: ['performance', 'bottlenecks', 'caching', 'data-access'],
  bugfix: ['error-handling', 'dataflow', 'state-management', 'edge-cases'],
  feature: ['patterns', 'integration-points', 'testing', 'dependencies']
}

function selectAngles(taskDescription, count) {
  const text = taskDescription.toLowerCase()
  let preset = 'feature' // default

  if (/refactor|architect|restructure|modular/.test(text)) preset = 'architecture'
  else if (/security|auth|permission|access/.test(text)) preset = 'security'
  else if (/performance|slow|optimi|cache/.test(text)) preset = 'performance'
  else if (/fix|bug|error|issue|broken/.test(text)) preset = 'bugfix'

  return ANGLE_PRESETS[preset].slice(0, count)
}

const selectedAngles = selectAngles(task_description, complexity === 'High' ? 4 : (complexity === 'Medium' ? 3 : 1))

console.log(`
## Exploration Plan

Task Complexity: ${complexity}
Selected Angles: ${selectedAngles.join(', ')}

Launching ${selectedAngles.length} parallel explorations...
`)
```

**Launch Parallel Explorations** - Orchestrator assigns angle to each agent:

**⚠️ CRITICAL - NO BACKGROUND EXECUTION**:
- **MUST NOT use `run_in_background: true`** - exploration results are REQUIRED before planning


```javascript
// Launch agents with pre-assigned angles
const explorationTasks = selectedAngles.map((angle, index) =>
  Task(
    subagent_type="cli-explore-agent",
    run_in_background=false,  // ⚠️ MANDATORY: Must wait for results
    description=`Explore: ${angle}`,
    prompt=`
## Task Objective
Execute **${angle}** exploration for task planning context. Analyze codebase from this specific angle to discover relevant structure, patterns, and constraints.

## Assigned Context
- **Exploration Angle**: ${angle}
- **Task Description**: ${task_description}
- **Exploration Index**: ${index + 1} of ${selectedAngles.length}
- **Output File**: ${sessionFolder}/exploration-${angle}.json

## MANDATORY FIRST STEPS (Execute by Agent)
**You (cli-explore-agent) MUST execute these steps in order:**
1. Run: ccw tool exec get_modules_by_depth '{}' (project structure)
2. Run: rg -l "{keyword_from_task}" --type ts (locate relevant files)
3. Execute: cat ~/.claude/workflows/cli-templates/schemas/explore-json-schema.json (get output schema reference)

## Exploration Strategy (${angle} focus)

**Step 1: Structural Scan** (Bash)
- get_modules_by_depth.sh → identify modules related to ${angle}
- find/rg → locate files relevant to ${angle} aspect
- Analyze imports/dependencies from ${angle} perspective

**Step 2: Semantic Analysis** (Gemini CLI)
- How does existing code handle ${angle} concerns?
- What patterns are used for ${angle}?
- Where would new code integrate from ${angle} viewpoint?

**Step 3: Write Output**
- Consolidate ${angle} findings into JSON
- Identify ${angle}-specific clarification needs

## Expected Output

**File**: ${sessionFolder}/exploration-${angle}.json

**Schema Reference**: Schema obtained in MANDATORY FIRST STEPS step 3, follow schema exactly

**Required Fields** (all ${angle} focused):
- project_structure: Modules/architecture relevant to ${angle}
- relevant_files: Files affected from ${angle} perspective
  **IMPORTANT**: Use object format with relevance scores for synthesis:
  \`[{path: "src/file.ts", relevance: 0.85, rationale: "Core ${angle} logic"}]\`
  Scores: 0.7+ high priority, 0.5-0.7 medium, <0.5 low
- patterns: ${angle}-related patterns to follow
- dependencies: Dependencies relevant to ${angle}
- integration_points: Where to integrate from ${angle} viewpoint (include file:line locations)
- constraints: ${angle}-specific limitations/conventions
- clarification_needs: ${angle}-related ambiguities (options array + recommended index)
- _metadata.exploration_angle: "${angle}"

## Success Criteria
- [ ] Schema obtained via cat explore-json-schema.json
- [ ] get_modules_by_depth.sh executed
- [ ] At least 3 relevant files identified with ${angle} rationale
- [ ] Patterns are actionable (code examples, not generic advice)
- [ ] Integration points include file:line locations
- [ ] Constraints are project-specific to ${angle}
- [ ] JSON output follows schema exactly
- [ ] clarification_needs includes options + recommended

## Output
Write: ${sessionFolder}/exploration-${angle}.json
Return: 2-3 sentence summary of ${angle} findings
`
  )
)

// Execute all exploration tasks in parallel
```

**Auto-discover Generated Exploration Files**:
```javascript
// After explorations complete, auto-discover all exploration-*.json files
const explorationFiles = bash(`find ${sessionFolder} -name "exploration-*.json" -type f`)
  .split('\n')
  .filter(f => f.trim())

// Read metadata to build manifest
const explorationManifest = {
  session_id: sessionId,
  task_description: task_description,
  timestamp: getUtc8ISOString(),
  complexity: complexity,
  exploration_count: explorationCount,
  explorations: explorationFiles.map(file => {
    const data = JSON.parse(Read(file))
    const filename = path.basename(file)
    return {
      angle: data._metadata.exploration_angle,
      file: filename,
      path: file,
      index: data._metadata.exploration_index
    }
  })
}

Write(`${sessionFolder}/explorations-manifest.json`, JSON.stringify(explorationManifest, null, 2))

console.log(`
## Exploration Complete

Generated exploration files in ${sessionFolder}:
${explorationManifest.explorations.map(e => `- exploration-${e.angle}.json (angle: ${e.angle})`).join('\n')}

Manifest: explorations-manifest.json
Angles explored: ${explorationManifest.explorations.map(e => e.angle).join(', ')}
`)
```

**Output**:
- `${sessionFolder}/exploration-{angle1}.json`
- `${sessionFolder}/exploration-{angle2}.json`
- ... (1-4 files based on complexity)
- `${sessionFolder}/explorations-manifest.json`

---

### Phase 2: Clarification (Optional, Multi-Round)

**Skip if**: No exploration or `clarification_needs` is empty across all explorations

**⚠️ CRITICAL**: AskUserQuestion tool limits max 4 questions per call. **MUST execute multiple rounds** to exhaust all clarification needs - do NOT stop at round 1.

**Aggregate clarification needs from all exploration angles**:
```javascript
// Load manifest and all exploration files
const manifest = JSON.parse(Read(`${sessionFolder}/explorations-manifest.json`))
const explorations = manifest.explorations.map(exp => ({
  angle: exp.angle,
  data: JSON.parse(Read(exp.path))
}))

// Aggregate clarification needs from all explorations
const allClarifications = []
explorations.forEach(exp => {
  if (exp.data.clarification_needs?.length > 0) {
    exp.data.clarification_needs.forEach(need => {
      allClarifications.push({
        ...need,
        source_angle: exp.angle
      })
    })
  }
})

// Intelligent deduplication: analyze allClarifications by intent
// - Identify questions with similar intent across different angles
// - Merge similar questions: combine options, consolidate context
// - Produce dedupedClarifications with unique intents only
const dedupedClarifications = intelligentMerge(allClarifications)

// Multi-round clarification: batch questions (max 4 per round)
if (dedupedClarifications.length > 0) {
  const BATCH_SIZE = 4
  const totalRounds = Math.ceil(dedupedClarifications.length / BATCH_SIZE)

  for (let i = 0; i < dedupedClarifications.length; i += BATCH_SIZE) {
    const batch = dedupedClarifications.slice(i, i + BATCH_SIZE)
    const currentRound = Math.floor(i / BATCH_SIZE) + 1

    console.log(`### Clarification Round ${currentRound}/${totalRounds}`)

    AskUserQuestion({
      questions: batch.map(need => ({
        question: `[${need.source_angle}] ${need.question}\n\nContext: ${need.context}`,
        header: need.source_angle.substring(0, 12),
        multiSelect: false,
        options: need.options.map((opt, index) => ({
          label: need.recommended === index ? `${opt} ★` : opt,
          description: need.recommended === index ? `Recommended` : `Use ${opt}`
        }))
      }))
    })

    // Store batch responses in clarificationContext before next round
  }
}
```

**Output**: `clarificationContext` (in-memory)

---

### Phase 3: Planning

**Planning Strategy Selection** (based on Phase 1 complexity):

**IMPORTANT**: Phase 3 is **planning only** - NO code execution. All execution happens in Phase 5 via lite-execute.

**Low Complexity** - Direct planning by Claude:
```javascript
// Step 1: Read schema
const schema = Bash(`cat ~/.claude/workflows/cli-templates/schemas/plan-json-schema.json`)

// Step 2: ⚠️ MANDATORY - Read and review ALL exploration files
const manifest = JSON.parse(Read(`${sessionFolder}/explorations-manifest.json`))
manifest.explorations.forEach(exp => {
  const explorationData = Read(exp.path)
  console.log(`\n### Exploration: ${exp.angle}\n${explorationData}`)
})

// Step 3: Generate plan following schema (Claude directly, no agent)
// ⚠️ Plan MUST incorporate insights from exploration files read in Step 2
const plan = {
  summary: "...",
  approach: "...",
  tasks: [...],  // Each task: { id, title, scope, ..., depends_on, execution_group, complexity }
  estimated_time: "...",
  recommended_execution: "Agent",
  complexity: "Low",
  _metadata: { timestamp: getUtc8ISOString(), source: "direct-planning", planning_mode: "direct" }
}

// Step 4: Write plan to session folder
Write(`${sessionFolder}/plan.json`, JSON.stringify(plan, null, 2))

// Step 5: MUST continue to Phase 4 (Confirmation) - DO NOT execute code here
```

**Medium/High Complexity** - Invoke cli-lite-planning-agent:

```javascript
Task(
  subagent_type="cli-lite-planning-agent",
  description="Generate detailed implementation plan",
  prompt=`
Generate implementation plan and write plan.json.

## Output Schema Reference
Execute: cat ~/.claude/workflows/cli-templates/schemas/plan-json-schema.json (get schema reference before generating plan)

## Task Description
${task_description}

## Multi-Angle Exploration Context

${manifest.explorations.map(exp => `### Exploration: ${exp.angle} (${exp.file})
Path: ${exp.path}

Read this file for detailed ${exp.angle} analysis.`).join('\n\n')}

Total explorations: ${manifest.exploration_count}
Angles covered: ${manifest.explorations.map(e => e.angle).join(', ')}

Manifest: ${sessionFolder}/explorations-manifest.json

## User Clarifications
${JSON.stringify(clarificationContext) || "None"}

## Complexity Level
${complexity}

## Requirements
Generate plan.json following the schema obtained above. Key constraints:
- tasks: 2-7 structured tasks (**group by feature/module, NOT by file**)
- _metadata.exploration_angles: ${JSON.stringify(manifest.explorations.map(e => e.angle))}

## Task Grouping Rules
1. **Group by feature**: All changes for one feature = one task (even if 3-5 files)
2. **Group by context**: Tasks with similar context or related functional changes can be grouped together
3. **Minimize agent count**: Simple, unrelated tasks can also be grouped to reduce agent execution overhead
4. **Avoid file-per-task**: Do NOT create separate tasks for each file
5. **Substantial tasks**: Each task should represent 15-60 minutes of work
6. **True dependencies only**: Only use depends_on when Task B cannot start without Task A's output
7. **Prefer parallel**: Most tasks should be independent (no depends_on)

## Execution
1. Read schema file (cat command above)
2. Read ALL exploration files for comprehensive context
3. Synthesize findings and generate plan following schema
4. Write JSON: Write('${sessionFolder}/plan.json', jsonContent)
5. Return brief completion summary
`
)
```

**Output**: `${sessionFolder}/plan.json`

---

### Phase 4: Task Confirmation & Execution Selection

**Step 4.1: Display Plan**
```javascript
const plan = JSON.parse(Read(`${sessionFolder}/plan.json`))

console.log(`
## Implementation Plan

**Summary**: ${plan.summary}
**Approach**: ${plan.approach}

**Tasks** (${plan.tasks.length}):
${plan.tasks.map((t, i) => `${i+1}. ${t.title} (${t.file})`).join('\n')}

**Complexity**: ${plan.complexity}
**Estimated Time**: ${plan.estimated_time}
**Recommended**: ${plan.recommended_execution}
`)
```

**Step 4.2: Collect Confirmation**
```javascript
AskUserQuestion({
  questions: [
    {
      question: `Confirm plan? (${plan.tasks.length} tasks, ${plan.complexity})`,
      header: "Confirm",
      multiSelect: true,
      options: [
        { label: "Allow", description: "Proceed as-is" },
        { label: "Modify", description: "Adjust before execution" },
        { label: "Cancel", description: "Abort workflow" }
      ]
    },
    {
      question: "Execution method:",
      header: "Execution",
      multiSelect: false,
      options: [
        { label: "Agent", description: "@code-developer agent" },
        { label: "Codex", description: "codex CLI tool" },
        { label: "Auto", description: `Auto: ${plan.complexity === 'Low' ? 'Agent' : 'Codex'}` }
      ]
    },
    {
      question: "Code review after execution?",
      header: "Review",
      multiSelect: false,
      options: [
        { label: "Gemini Review", description: "Gemini CLI" },
        { label: "Agent Review", description: "@code-reviewer" },
        { label: "Skip", description: "No review" }
      ]
    }
  ]
})
```

---

### Phase 5: Dispatch to Execution

**CRITICAL**: lite-plan NEVER executes code directly. ALL execution MUST go through lite-execute.

**Step 5.1: Build executionContext**

```javascript
// Load manifest and all exploration files
const manifest = JSON.parse(Read(`${sessionFolder}/explorations-manifest.json`))
const explorations = {}

manifest.explorations.forEach(exp => {
  if (file_exists(exp.path)) {
    explorations[exp.angle] = JSON.parse(Read(exp.path))
  }
})

const plan = JSON.parse(Read(`${sessionFolder}/plan.json`))

executionContext = {
  planObject: plan,
  explorationsContext: explorations,
  explorationAngles: manifest.explorations.map(e => e.angle),
  explorationManifest: manifest,
  clarificationContext: clarificationContext || null,
  executionMethod: userSelection.execution_method,
  codeReviewTool: userSelection.code_review_tool,
  originalUserInput: task_description,
  session: {
    id: sessionId,
    folder: sessionFolder,
    artifacts: {
      explorations: manifest.explorations.map(exp => ({
        angle: exp.angle,
        path: exp.path
      })),
      explorations_manifest: `${sessionFolder}/explorations-manifest.json`,
      plan: `${sessionFolder}/plan.json`
    }
  }
}
```

**Step 5.2: Dispatch**

```javascript
SlashCommand(command="/workflow:lite-execute --in-memory")
```

## Session Folder Structure

```
.workflow/.lite-plan/{task-slug}-{YYYY-MM-DD}/
├── exploration-{angle1}.json      # Exploration angle 1
├── exploration-{angle2}.json      # Exploration angle 2
├── exploration-{angle3}.json      # Exploration angle 3 (if applicable)
├── exploration-{angle4}.json      # Exploration angle 4 (if applicable)
├── explorations-manifest.json     # Exploration index
└── plan.json                      # Implementation plan
```

**Example**:
```
.workflow/.lite-plan/implement-jwt-refresh-2025-11-25-14-30-25/
├── exploration-architecture.json
├── exploration-auth-patterns.json
├── exploration-security.json
├── explorations-manifest.json
└── plan.json
```

## Error Handling

| Error | Resolution |
|-------|------------|
| Exploration agent failure | Skip exploration, continue with task description only |
| Planning agent failure | Fallback to direct planning by Claude |
| Clarification timeout | Use exploration findings as-is |
| Confirmation timeout | Save context, display resume instructions |
| Modify loop > 3 times | Suggest breaking task or using /workflow:plan |
