+## Level 5: Intelligent Orchestration (CCW Coordinator)
+
+**Most Intelligent - Automated command chain orchestration + Sequential execution + State persistence**
+
+### Core Concept: Minimum Execution Units
+
+**Definition**: A set of commands that must execute together as an atomic group to achieve a meaningful workflow milestone. Splitting these commands breaks the logical flow and creates incomplete states.
+
+**Why This Matters**:
+- **Prevents Incomplete States**: Avoid stopping after task generation without execution
+- **User Experience**: User gets complete results, not intermediate artifacts requiring manual follow-up
+- **Workflow Integrity**: Maintains logical coherence of multi-step operations
+
+### Minimum Execution Units
+
+**Planning + Execution Units**:
+
+| Unit Name | Commands | Purpose | Output |
+|-----------|----------|---------|--------|
+| **Quick Implementation** | lite-plan → lite-execute | Lightweight plan and immediate execution | Working code |
+| **Multi-CLI Planning** | multi-cli-plan → lite-execute | Multi-perspective analysis and execution | Working code |
+| **Bug Fix** | lite-fix → lite-execute | Quick bug diagnosis and fix execution | Fixed code |
+| **Full Planning + Execution** | plan → execute | Detailed planning and execution | Working code |
+| **Verified Planning + Execution** | plan → plan-verify → execute | Planning with verification and execution | Working code |
+| **Replanning + Execution** | replan → execute | Update plan and execute changes | Working code |
+| **TDD Planning + Execution** | tdd-plan → execute | Test-driven development planning and execution | Working code |
+| **Test Generation + Execution** | test-gen → execute | Generate test suite and execute | Generated tests |
+
+**Testing Units**:
+
+| Unit Name | Commands | Purpose | Output |
+|-----------|----------|---------|--------|
+| **Test Validation** | test-fix-gen → test-cycle-execute | Generate test tasks and execute test-fix cycle | Tests passed |
+
+**Review Units**:
+
+| Unit Name | Commands | Purpose | Output |
+|-----------|----------|---------|--------|
+| **Code Review (Session)** | review-session-cycle → review-fix | Complete review cycle and apply fixes | Fixed code |
+| **Code Review (Module)** | review-module-cycle → review-fix | Module review cycle and apply fixes | Fixed code |
+
+### 3-Phase Workflow
+
+#### Phase 1: Analyze Requirements
+
+Parse task description to extract: goal, scope, constraints, complexity, and task type.
+
+```javascript
+function analyzeRequirements(taskDescription) {
+  return {
+    goal: extractMainGoal(taskDescription),           // e.g., "Implement user registration"
+    scope: extractScope(taskDescription),             // e.g., ["auth", "user_management"]
+    constraints: extractConstraints(taskDescription), // e.g., ["no breaking changes"]
+    complexity: determineComplexity(taskDescription), // 'simple' | 'medium' | 'complex'
+    task_type: detectTaskType(taskDescription)        // See task type patterns below
+  };
+}
+
+// Task Type Detection Patterns
+function detectTaskType(text) {
+  // Priority order (first match wins)
+  if (/fix|bug|error|crash|fail|debug|diagnose/.test(text)) return 'bugfix';
+  if (/tdd|test-driven|test first/.test(text)) return 'tdd';
+  if (/test fail|fix test|failing test/.test(text)) return 'test-fix';
+  if (/generate test|add test/.test(text)) return 'test-gen';
+  if (/review/.test(text)) return 'review';
+  if (/explore|brainstorm/.test(text)) return 'brainstorm';
+  if (/multi-perspective|comparison/.test(text)) return 'multi-cli';
+  return 'feature';  // Default
+}
+
+// Complexity Assessment
+function determineComplexity(text) {
+  let score = 0;
+  if (/refactor|migrate|architect|system/.test(text)) score += 2;
+  if (/multiple|across|all|entire/.test(text)) score += 2;
+  if (/integrate|api|database/.test(text)) score += 1;
+  if (/security|performance|scale/.test(text)) score += 1;
+  return score >= 4 ? 'complex' : score >= 2 ? 'medium' : 'simple';
+}
+```
+
+#### Phase 2: Discover Commands & Recommend Chain
+
+Dynamic command chain assembly using port-based matching.
+
+**Display to user**:
+```
+Recommended Command Chain:
+
+Pipeline (visual):
+Requirement → lite-plan → Plan → lite-execute → Code → test-cycle-execute → Tests Passed
+
+Commands:
+1. /workflow:lite-plan
+2. /workflow:lite-execute
+3. /workflow:test-cycle-execute
+
+Proceed? [Confirm / Show Details / Adjust / Cancel]
+```
+
+**User Confirmation**:
+```javascript
+async function getUserConfirmation(chain) {
+  // Present chain with options:
+  // - Confirm and execute
+  // - Show details
+  // - Adjust chain
+  // - Cancel
+}
+```
+
+#### Phase 3: Execute Sequential Command Chain
+
+```javascript
+async function executeCommandChain(chain, analysis) {
+  const sessionId = `ccw-coord-${Date.now()}`;
+  const stateDir = `.workflow/.ccw-coordinator/${sessionId}`;
+
+  // Initialize state
+  const state = {
+    session_id: sessionId,
+    status: 'running',
+    created_at: new Date().toISOString(),
+    analysis: analysis,
+    command_chain: chain.map((cmd, idx) => ({ ...cmd, index: idx, status: 'pending' })),
+    execution_results: [],
+    prompts_used: []
+  };
+
+  // Save initial state
+  Write(`${stateDir}/state.json`, JSON.stringify(state, null, 2));
+
+  for (let i = 0; i < chain.length; i++) {
+    const cmd = chain[i];
+
+    // Assemble prompt
+    let prompt = formatCommand(cmd, state.execution_results, analysis);
+    prompt += `\n\nTask: ${analysis.goal}`;
+    if (state.execution_results.length > 0) {
+      prompt += '\n\nPrevious results:\n';
+      state.execution_results.forEach(r => {
+        if (r.session_id) {
+          prompt += `- ${r.command}: ${r.session_id}\n`;
+        }
+      });
+    }
+
+    // Launch CLI in background
+    const taskId = Bash(
+      `ccw cli -p "${escapePrompt(prompt)}" --tool claude --mode write`,
+      { run_in_background: true }
+    ).task_id;
+
+    // Save checkpoint
+    state.execution_results.push({
+      index: i,
+      command: cmd.command,
+      status: 'in-progress',
+      task_id: taskId,
+      session_id: null,
+      artifacts: [],
+      timestamp: new Date().toISOString()
+    });
+
+    // Stop here - wait for hook callback
+    Write(`${stateDir}/state.json`, JSON.stringify(state, null, 2));
+    break;
+  }
+
+  state.status = 'waiting';
+  Write(`${stateDir}/state.json`, JSON.stringify(state, null, 2));
+  return state;
+}
+```

+# Auto-analyze → recommend command chain → execute sequentially
+```
+
+### Use Cases
+
+- ✅ Complex multi-step workflows
+- ✅ Uncertain which commands to use
+- ✅ Desire end-to-end automation
+- ✅ Need full state tracking and resumability
+- ✅ Team collaboration with unified execution flow
+- ❌ Simple single-command tasks
+- ❌ Already know exact commands needed
+
+### Relationship with Other Levels
+
+| Level | Manual Degree | CCW Coordinator Role |
+|-------|---------------|-----------------------|
+| Level 1-4 | Manual command selection | Auto-combine these commands |
+| Level 5 | Auto command selection | Intelligent orchestrator |
+
+**CCW Coordinator uses Level 1-4 internally**:
+- Analyzes task → Auto-selects appropriate Level
+- Assembles command chain → Includes Level 1-4 commands
+- Executes sequentially → Follows Minimum Execution Units
