+# Codex Unified-Execute-With-File Prompt
+
+## Overview
+
+Universal execution engine that consumes **any** planning/brainstorm/analysis output and executes it with minimal progress tracking. Coordinates multiple agents (code-developer, test-fix-agent, doc-generator, cli-execution-agent), handles dependencies intelligently, and maintains unified execution timeline.
+
+**Core workflow**: Load Plan → Parse Tasks → Validate Dependencies → Execute Waves → Track Progress → Report Results
+
+**Key features**:
+- **Plan Format Agnostic**: Consumes IMPL_PLAN.md, brainstorm synthesis.json, analysis conclusions.json, debug resolutions
+- **execution-events.md**: Single source of truth - unified execution log with full agent history
+- **Multi-Agent Orchestration**: Parallel execution where possible, sequential where needed
+- **Incremental Execution**: Resume from failure point, no re-execution of completed tasks
+- **Dependency Management**: Automatic topological sort and execution wave grouping
+- **Knowledge Chain**: Each agent reads all previous execution history in context
+
+## Target Execution Plan
+
+**Plan Source**: $PLAN_PATH
+
+- `EXECUTION_MODE`: Strategy (sequential|parallel)
+- `AUTO_CONFIRM`: Skip confirmations (yes|no)
+- `EXECUTION_CONTEXT`: Focus area/module (optional)
+
+## Execution Process
+
+```
+Session Detection:
+   ├─ Check if execution session exists
+   ├─ If exists → Resume mode
+   └─ If not → New session mode
+
+Phase 1: Plan Loading & Validation
+   ├─ Detect and parse plan file (multiple formats supported)
+   ├─ Extract and normalize tasks
+   ├─ Validate dependencies (detect cycles)
+   ├─ Create execution session folder
+   ├─ Initialize execution.md and execution-events.md
+   └─ Pre-execution validation
+
+Phase 2: Execution Orchestration
+   ├─ Topological sort for execution order
+   ├─ Group tasks into execution waves (parallel-safe groups)
+   ├─ Execute waves sequentially (tasks within wave execute in parallel)
+   ├─ Monitor completion and capture artifacts
+   ├─ Update progress in execution.md and execution-events.md
+   └─ Handle failures with retry/skip/abort logic
+
+Phase 3: Progress Tracking & Unified Event Logging
+   ├─ execution-events.md: Append-only unified log (SINGLE SOURCE OF TRUTH)
+   ├─ Each agent reads all previous events at start
+   ├─ Agent executes task with full context from previous agents
+   ├─ Agent appends execution event (success/failure) with artifacts and notes
+   └─ Next agent reads complete history → knowledge chain
+
+Phase 4: Completion & Summary
+   ├─ Collect execution statistics
+   ├─ Update execution.md with final status
+   ├─ execution-events.md contains complete execution record
+   └─ Report results and offer follow-up options
+```

+## Implementation Details
+
+### Session Setup & Plan Detection
+
+```javascript

+### Plan Format Parsers
+
+Support multiple plan sources:

+  }
+}
+```
+
+---
+
+## Phase 1: Plan Loading & Validation
+
+### Step 1.1: Parse Plan and Extract Tasks
+
+```javascript
+const tasks = plan.tasks || parseTasksFromContent(plan)
+
+// Normalize task structure
+const normalizedTasks = tasks.map(task => ({
+  id: task.id || `TASK-${generateId()}`,
+  title: task.title || task.content,

+
+// Validate and detect issues
+const validation = {
+  cycles: detectDependencyCycles(normalizedTasks),
+  missing_dependencies: findMissingDependencies(normalizedTasks),
+  file_conflicts: detectOutputConflicts(normalizedTasks),
+  warnings: []
+}
+
+if (validation.cycles.length > 0) {
+  throw new Error(`Circular dependencies detected: ${validation.cycles.join(', ')}`)
+}
+```
+
+### Step 1.2: Create execution.md
+
+```javascript
+const executionMarkdown = `# Execution Progress

+
+## Phase 2: Execution Orchestration
+
+### Step 2.1: Determine Execution Order
+
+```javascript

+
+## Phase 3: Progress Tracking & Event Logging
+
+**execution-events.md** is the **SINGLE SOURCE OF TRUTH**:
+- Append-only, chronological execution log
+- Each task records: timestamp, duration, agent type, execution summary, artifacts, notes for next agent
+- Failures include error details and recovery notes
+- Format: Human-readable markdown with machine-parseable status indicators (✅/❌/⏳)
+
+**Event log format** (appended entry):
+```markdown
+## Task {id} - {STATUS} {emoji}
+
+**Timestamp**: {time}
+**Duration**: {ms}
+**Agent**: {type}
+
+### Execution Summary
+{What was done}
+
+### Generated Artifacts
+- `src/types/auth.ts` (2.3KB)
+
+### Notes for Next Agent
+- Key decisions made
+- Potential issues
+- Ready for: TASK-003
+```
+
+---
+
+## Phase 4: Completion & Summary
+
+After all tasks complete or max failures reached:
+
+```javascript
+const statistics = {
+  total_tasks: normalizedTasks.length,
+  completed: normalizedTasks.filter(t => t.status === 'completed').length,
+  failed: normalizedTasks.filter(t => t.status === 'failed').length,
+  skipped: normalizedTasks.filter(t => t.status === 'skipped').length,
+  success_rate: (completedCount / normalizedTasks.length * 100).toFixed(1)
+}
+
+// Update execution.md with final status
+appendExecutionSummary(executionPath, statistics)
+```
+
+**Post-Completion Options** (unless auto-confirm):
+
+```javascript
+AskUserQuestion({
+  questions: [{
+    question: "执行完成。是否需要后续操作?",
+    header: "Next Steps",
+    multiSelect: true,
+    options: [

+      { label: "优化执行", description: "分析执行改进建议" },
+      { label: "完成", description: "不需要后续操作" }
+    ]
+  }]
+})
+```
+
+---
+
+## Session Folder Structure
+
+```
+.workflow/.execution/{executionId}/

+# Generated files go directly to project directories (not into execution folder)
+# E.g., TASK-001 generates: src/types/auth.ts (not artifacts/src/types/auth.ts)
+# execution-events.md records the actual project paths
+```
+
+---
+
+## Agent Selection Strategy
+
+```javascript
+function selectBestAgent(task) {
+  if (task.type === 'code' || task.type === 'implementation') {
+    return task.includes_tests ? 'tdd-developer' : 'code-developer'

+
+## Parallelization Rules
+
+```javascript
+function calculateParallel(tasks) {
+  // Group tasks into execution waves
+  // Constraints:
+  // - Tasks with same file modifications must be sequential
+  // - Tasks with dependencies must wait
+  // - Max 3 parallel tasks per wave (resource constraint)
+
+  const waves = []
+  const completed = new Set()
+
+  while (completed.size < tasks.length) {
+    const available = tasks.filter(t =>
+      !completed.has(t.id) &&
+      t.dependencies.every(d => completed.has(d))
+    )
+
+    if (available.length === 0) break
+
+    // Check for file conflicts
+    const noConflict = []
+    const modifiedFiles = new Set()
+
+    for (const task of available) {
+      const conflicts = task.files_to_modify.some(f => modifiedFiles.has(f))
+      if (!conflicts && noConflict.length < 3) {
+        noConflict.push(task)
+        task.files_to_modify.forEach(f => modifiedFiles.add(f))
+      }
+    }
+
+    if (noConflict.length > 0) {
+      waves.push(noConflict)
+      noConflict.forEach(t => completed.add(t.id))
+    }
+  }
+
+  return waves
+}
+```

+
+## Error Handling & Recovery
+
+| Situation | Action |
+|-----------|--------|
+| Task timeout | Mark as timeout, ask user: retry/skip/abort |
+| Missing dependency | Auto-skip dependent tasks, log warning |
+| File conflict | Detect before execution, ask for resolution |
+| Output mismatch | Validate against expected_output, flag for review |
+| Agent unavailable | Fallback to universal-executor |
+
+---
+
+## Usage Recommendations
+
+Use this execution engine when:
+- Executing any planning document (IMPL_PLAN.md, brainstorm conclusions, analysis recommendations)
+- Multiple tasks with dependencies need orchestration
+- Want minimal progress tracking without clutter
+- Need to handle failures gracefully and resume
+- Want to parallelize where possible but ensure correctness
+
+Consumes output from:
+- `/workflow:plan` → IMPL_PLAN.md
+- `/workflow:brainstorm-with-file` → synthesis.json → execution
+- `/workflow:analyze-with-file` → conclusions.json → execution
+- `/workflow:debug-with-file` → recommendations → execution
+- `/workflow:lite-plan` → task JSONs → execution
