+description: Command orchestration tool for Codex - analyze requirements, recommend command chain, execute sequentially with state persistence
+argument-hint: "TASK=\"<task description>\" [--depth=standard|deep] [--auto-confirm] [--verbose]"
+---
+
+# Codex Coordinator Command
+
+Interactive orchestration tool for Codex commands: analyze task → discover commands → recommend chain → execute sequentially → track state.
+
+**Execution Model**: Intelligent agent-driven workflow. Claude analyzes each phase and orchestrates command execution.
+
+## Core Concept: Minimum Execution Units (最小执行单元)
+
+### What is a Minimum Execution Unit?
+
+**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
+
+### Codex Minimum Execution Units
+
+**Planning + Execution Units** (规划+执行单元):
+
+| Unit Name | Commands | Purpose | Output |
+|-----------|----------|---------|--------|
+| **Quick Implementation** | lite-plan-a → execute | Lightweight plan and immediate execution | Working code |
+| **Bug Fix** | lite-fix → execute | Quick bug diagnosis and fix execution | Fixed code |
+| **Issue Workflow** | issue-discover → issue-plan → issue-queue → issue-execute | Complete issue lifecycle | Completed issues |
+| **Discovery & Analysis** | issue-discover → issue-discover-by-prompt | Issue discovery with multiple perspectives | Generated issues |
+| **Brainstorm to Execution** | brainstorm-with-file → execute | Brainstorm ideas then implement | Working code |
+
+**With-File Workflows** (文档化单元):
+
+| Unit Name | Commands | Purpose | Output |
+|-----------|----------|---------|--------|
+| **Brainstorm With File** | brainstorm-with-file | Multi-perspective ideation with documentation | brainstorm.md |
+| **Debug With File** | debug-with-file | Hypothesis-driven debugging with documentation | understanding.md |
+| **Analyze With File** | analyze-with-file | Collaborative analysis with documentation | discussion.md |
+| **Clean & Analyze** | clean → analyze-with-file | Cleanup then analyze | Cleaned code + analysis |
+
+### Command-to-Unit Mapping (命令与最小单元的映射)
+
+| Command | Precedes | Atomic Units |
+|---------|----------|--------------|
+| lite-plan-a | execute, brainstorm-with-file | Quick Implementation |
+| lite-fix | execute | Bug Fix |
+| issue-discover | issue-plan | Issue Workflow |
+| issue-plan | issue-queue | Issue Workflow |
+| issue-queue | issue-execute | Issue Workflow |
+| brainstorm-with-file | execute, issue-execute | Brainstorm to Execution |
+| debug-with-file | execute | Debug With File |
+| analyze-with-file | (standalone) | Analyze With File |
+| clean | analyze-with-file, execute | Clean & Analyze |
+| quick-plan-with-file | execute | Quick Planning with File |
+| merge-plans-with-file | execute | Merge Multiple Plans |
+| unified-execute-with-file | (terminal) | Execute with File Tracking |
+
+### Atomic Group Rules
+
+1. **Never Split Units**: Coordinator must recommend complete units, not partial chains
+2. **Multi-Unit Participation**: Some commands can participate in multiple units
+3. **User Override**: User can explicitly request partial execution (advanced mode)
+4. **Visualization**: Pipeline view shows unit boundaries with 【 】markers
+5. **Validation**: Before execution, verify all unit commands are included
+
+**Example Pipeline with Units**:
+```
+需求 → 【lite-plan-a → execute】→ 代码 → 【issue-discover → issue-plan → issue-queue → issue-execute】→ 完成
+       └──── Quick Implementation ────┘         └────────── Issue Workflow ─────────┘
+```
+
+## 3-Phase Workflow
+
+### Phase 1: Analyze Requirements
+
+Parse task to extract: goal, scope, complexity, and task type.
+
+```javascript
+function analyzeRequirements(taskDescription) {
+  return {
+    goal: extractMainGoal(taskDescription),           // e.g., "Fix login bug"
+    scope: extractScope(taskDescription),             // e.g., ["auth", "login"]
+    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 (/生成|generate|discover|找出|issue|问题/.test(text)) return 'discovery';
+  if (/plan|规划|设计|design|analyze|分析/.test(text)) return 'analysis';
+  if (/清理|cleanup|clean|refactor|重构/.test(text)) return 'cleanup';
+  if (/头脑|brainstorm|创意|ideation/.test(text)) return 'brainstorm';
+  if (/合并|merge|combine|batch/.test(text)) return 'batch-planning';
+  return 'feature';  // Default
+}
+
+// Complexity Assessment
+function determineComplexity(text) {
+  let score = 0;
+  if (/refactor|重构|migrate|迁移|architect|架构|system|系统/.test(text)) score += 2;
+  if (/multiple|多个|across|跨|all|所有|entire|整个/.test(text)) score += 2;
+  if (/integrate|集成|api|database|数据库/.test(text)) score += 1;
+  if (/security|安全|performance|性能|scale|扩展/.test(text)) score += 1;
+  return score >= 4 ? 'complex' : score >= 2 ? 'medium' : 'simple';
+}
+```
+
+**Display to user**:
+```
+Analysis Complete:
+  Goal: [extracted goal]
+  Scope: [identified areas]
+  Complexity: [level]
+  Task Type: [detected type]
+```
+
+### Phase 2: Discover Commands & Recommend Chain
+
+Dynamic command chain assembly using task type and complexity matching.
+
+#### Available Codex Commands (Discovery)
+
+All commands from `~/.codex/prompts/`:
+- **Planning**: @~/.codex/prompts/lite-plan-a.md, @~/.codex/prompts/lite-plan-b.md, @~/.codex/prompts/lite-plan-c.md, @~/.codex/prompts/quick-plan-with-file.md, @~/.codex/prompts/merge-plans-with-file.md

+
+#### Recommendation Algorithm
+
+```javascript
+async function recommendCommandChain(analysis) {
+  // Step 1: 根据任务类型确定流程
+  const { inputPort, outputPort } = determinePortFlow(analysis.task_type, analysis.complexity);
+
+  // Step 2: Claude 根据命令特性和任务特征，智能选择命令序列
+  const chain = selectChainByTaskType(analysis);
+
+  return chain;
+}
+
+// 任务类型对应的端口流
+function determinePortFlow(taskType, complexity) {
+  const flows = {
+    'bugfix':       { flow: ['lite-fix', 'execute'], depth: complexity === 'complex' ? 'deep' : 'standard' },
+    'discovery':    { flow: ['issue-discover', 'issue-plan', 'issue-queue', 'issue-execute'], depth: 'standard' },
+    'analysis':     { flow: ['analyze-with-file'], depth: complexity === 'complex' ? 'deep' : 'standard' },
+    'cleanup':      { flow: ['clean'], depth: 'standard' },
+    'brainstorm':   { flow: ['brainstorm-with-file', 'execute'], depth: complexity === 'complex' ? 'deep' : 'standard' },
+    'batch-planning': { flow: ['merge-plans-with-file', 'execute'], depth: 'standard' },
+    'feature':      { flow: complexity === 'complex' ? ['lite-plan-b'] : ['lite-plan-a', 'execute'], depth: complexity === 'complex' ? 'deep' : 'standard' }
+  };
+  return flows[taskType] || flows['feature'];
+}
+```
+
+#### Display to User
+
+```
+Recommended Command Chain:
+
+Pipeline (管道视图):
+需求 → @~/.codex/prompts/lite-plan-a.md → 计划 → @~/.codex/prompts/execute.md → 代码完成
+
+Commands (命令列表):
+1. @~/.codex/prompts/lite-plan-a.md
+2. @~/.codex/prompts/execute.md
+
+Proceed? [Confirm / Show Details / Adjust / Cancel]
+```
+
+### Phase 2b: Get User Confirmation
+
+Ask user for confirmation before proceeding with execution.
+
+```javascript
+async function getUserConfirmation(chain) {
+  const response = await AskUserQuestion({
+    questions: [{
+      question: 'Proceed with this command chain?',
+      header: 'Confirm Chain',
+      multiSelect: false,
+      options: [
+        { label: 'Confirm and execute', description: 'Proceed with commands' },
+        { label: 'Show details', description: 'View each command' },
+        { label: 'Adjust chain', description: 'Remove or reorder' },
+        { label: 'Cancel', description: 'Abort' }
+      ]
+    }]
+  });
+
+  return response;
+}
+```
+
+### Phase 3: Execute Sequential Command Chain
+
+```javascript
+async function executeCommandChain(chain, analysis) {
+  const sessionId = `codex-coord-${Date.now()}`;
+  const stateDir = `.workflow/.codex-coordinator/${sessionId}`;
+
+  // Create state directory
+  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: [],
+  };
+

+        commandStr += ` --resume="${lastResult.session_id || lastResult.artifact}"`;
+      }
+
+      // For analysis-based commands, add depth parameter
+      if (analysis.complexity === 'complex' && (cmd.name.includes('analyze') || cmd.name.includes('plan'))) {
+        commandStr += ` --depth=deep`;
+      }
+
+      // Add task description for planning commands
+      if (cmd.type === 'planning' && i === 0) {
+        commandStr += ` TASK="${analysis.goal}"`;
+      }
+
+      // Execute command via Bash (spawning as background task)
+      // Format: @~/.codex/prompts/command-name.md [] parameters
+      // Note: This simulates the execution; actual implementation uses hook callbacks
+      console.log(`Executing: ${commandStr}`);
+
+      // Save execution record
+      state.execution_results.push({
+        index: i,

+      state.updated_at = new Date().toISOString();
+      Write(`${stateDir}/state.json`, JSON.stringify(state, null, 2));
+
+      console.log(`[${i+1}/${chain.length}] ✓ Completed: @~/.codex/prompts/${cmd.name}.md`);
+
+    } catch (error) {
+      state.command_chain[i].status = 'failed';
+      state.updated_at = new Date().toISOString();
+      Write(`${stateDir}/state.json`, JSON.stringify(state, null, 2));

+      console.log(`❌ Command failed: ${error.message}`);
+      break;
+    }
+  }

+
+## Key Design Principles
+
+1. **Atomic Execution** - Never split minimum execution units
+2. **State Persistence** - All state saved to JSON
+3. **User Control** - Confirmation before execution
+4. **Context Passing** - Parameters chain across commands
+5. **Resume Support** - Can resume from state.json
+6. **Intelligent Routing** - Task type determines command chain
+7. **Complexity Awareness** - Different paths for simple vs complex tasks
+
+## Command Invocation Format
+
+**Format**: `@~/.codex/prompts/<command-name>.md <parameters>`
+
+**Examples**:
+```bash
+@~/.codex/prompts/lite-plan-a.md TASK="Implement user authentication"
+@~/.codex/prompts/execute.md SESSION=".workflow/.lite-plan/..."
+@~/.codex/prompts/lite-fix.md BUG="Login fails with 404 error"
+@~/.codex/prompts/issue-discover.md PATTERN="src/auth/**"
+@~/.codex/prompts/brainstorm-with-file.md TOPIC="Improve user onboarding"
+```
+
+## Error Handling
+
+| Situation | Action |
+|-----------|--------|
+| Unknown task type | Default to feature implementation |
+| Command not found | Error: command not available |
+| Execution fails | Report error, offer retry or skip |
+| Invalid parameters | Validate and ask for correction |
+| Circular dependency | Detect and report |
+| All commands fail | Report and suggest manual intervention |
+
+## Session Management
+
+**Resume Previous Session**:
+```
+1. Find session in .workflow/.codex-coordinator/
+2. Load state.json
+3. Identify last completed command
+4. Restart from next pending command
+```
+
+**View Session Progress**:
+```
+cat .workflow/.codex-coordinator/{session-id}/state.json
+```
+
+---
+
+## Execution Instructions
+
+The coordinator workflow follows these steps:
+
+1. **Parse Input**: Extract task description from TASK parameter
+2. **Analyze**: Determine goal, scope, complexity, and task type
+3. **Recommend**: Build optimal command chain based on analysis
+4. **Confirm**: Display pipeline and request user approval
+5. **Execute**: Run commands sequentially with state tracking
+6. **Report**: Display final results and artifacts
+
+To use this coordinator, invoke it as a Claude Code command (not a Codex command):
+
+From the Claude Code CLI, you would call Codex commands like:
+```bash
+@~/.codex/prompts/lite-plan-a.md TASK="Your task description"
+```
+
+Or with options:
+```bash
+@~/.codex/prompts/lite-plan-a.md TASK="..." --depth=deep
+```
+
+This coordinator orchestrates such Codex commands based on your task requirements.
