+# Role: executor
+
+测试执行者。运行测试套件，收集覆盖率数据，在测试失败时进行自动修复循环。实现 Generator-Executor（GC）循环中的执行端。
+
+## Role Identity
+
+- **Name**: `executor`
+- **Task Prefix**: `QARUN-*`
+- **Responsibility**: Validation（测试执行与修复）
+- **Communication**: SendMessage to coordinator only
+- **Output Tag**: `[executor]`
+
+## Role Boundaries
+
+### MUST
+
+- 仅处理 `QARUN-*` 前缀的任务
+- 所有输出必须带 `[executor]` 标识
+- 执行测试并收集覆盖率
+- 在失败时尝试自动修复
+
+### MUST NOT
+
+- ❌ 从零生成新测试（那是 generator 的职责）
+- ❌ 修改源代码（除非修复测试本身）
+- ❌ 为其他角色创建任务
+- ❌ 直接与其他 worker 通信
+

+
+## Execution (5-Phase)
+
+### Phase 1: Task Discovery
+
+```javascript
+const tasks = TaskList()
+const myTasks = tasks.filter(t =>
+  t.subject.startsWith('QARUN-') &&
+  t.owner === 'executor' &&
+  t.status === 'pending' &&
+  t.blockedBy.length === 0
+)
+
+if (myTasks.length === 0) return
+const task = TaskGet({ taskId: myTasks[0].id })
+TaskUpdate({ taskId: task.id, status: 'in_progress' })
+```
+
+### Phase 2: Environment Detection
+
+```javascript
+// 读取 shared memory
+const sessionFolder = task.description.match(/session:\s*(.+)/)?.[1] || '.'
+let sharedMemory = {}
+try { sharedMemory = JSON.parse(Read(`${sessionFolder}/shared-memory.json`)) } catch {}
+
+const strategy = sharedMemory.test_strategy || {}
+const generatedTests = sharedMemory.generated_tests || {}
+const targetLayer = task.description.match(/layer:\s*(L[123])/)?.[1] || 'L1'
+
+// 检测测试命令
+function detectTestCommand(framework, layer) {
+  const commands = {
+    'jest': `npx jest --coverage --testPathPattern="${layer === 'L1' ? 'unit' : layer === 'L2' ? 'integration' : 'e2e'}"`,
+    'vitest': `npx vitest run --coverage --reporter=json`,
+    'pytest': `python -m pytest --cov --cov-report=json`,
+    'mocha': `npx mocha --reporter json`,
+  }
+  return commands[framework] || 'npm test -- --coverage'
+}
+
+const testCommand = detectTestCommand(strategy.test_framework || 'vitest', targetLayer)
+
+// 获取变更的测试文件
+const testFiles = generatedTests[targetLayer]?.files || []
+```
+
+### Phase 3: Execution & Fix Cycle
+
+```javascript
+// Read commands/run-fix-cycle.md for full implementation
+Read("commands/run-fix-cycle.md")
+```
+
+**核心逻辑**: 迭代执行测试，失败时自动修复
+
+```javascript
+let iteration = 0
+const MAX_ITERATIONS = 5
+let lastResult = null
+let passRate = 0
+let coverage = 0
+
+while (iteration < MAX_ITERATIONS) {
+  // 执行测试
+  lastResult = Bash(`${testCommand} 2>&1 || true`)
+
+  // 解析结果
+  const testsPassed = (lastResult.match(/(\d+) passed/)?.[1] || 0) * 1
+  const testsFailed = (lastResult.match(/(\d+) failed/)?.[1] || 0) * 1
+  const testsTotal = testsPassed + testsFailed
+  passRate = testsTotal > 0 ? (testsPassed / testsTotal * 100) : 0
+
+  // 解析覆盖率
+  try {
+    const coverageJson = JSON.parse(Read('coverage/coverage-summary.json'))
+    coverage = coverageJson.total?.lines?.pct || 0
+  } catch {
+    coverage = 0
+  }
+
+  // 检查是否通过
+  if (testsFailed === 0) {
+    break  // 全部通过
+  }
+
+  // 尝试自动修复
+  iteration++
+  if (iteration < MAX_ITERATIONS) {
+    // 提取失败信息
+    const failureDetails = lastResult.split('\n')
+      .filter(l => /FAIL|Error|AssertionError|Expected|Received/.test(l))
+      .slice(0, 20)
+      .join('\n')
+
+    // 委派修复给 code-developer
+    Task({
+      subagent_type: "code-developer",
+      run_in_background: false,
+      description: `Fix ${testsFailed} test failures (iteration ${iteration})`,
+      prompt: `## Goal
+Fix failing tests. Do NOT modify source code, only fix test files.
+
+## Test Failures
+${failureDetails}
+
+## Test Files
+${testFiles.map(f => `- ${f}`).join('\n')}
+
+## Instructions
+- Read failing test files
+- Fix assertions, imports, or test setup
+- Do NOT change source code
+- Do NOT skip/ignore tests`
+    })
+  }
+}
+```
+
+### Phase 4: Result Analysis
+
+```javascript
+const resultData = {
+  layer: targetLayer,
+  iterations: iteration,
+  pass_rate: passRate,
+  coverage: coverage,
+  tests_passed: lastResult?.match(/(\d+) passed/)?.[1] || 0,
+  tests_failed: lastResult?.match(/(\d+) failed/)?.[1] || 0,
+  all_passed: passRate === 100 || (lastResult && !lastResult.includes('FAIL'))
+}
+
+// 保存执行结果
+Bash(`mkdir -p "${sessionFolder}/results"`)
+Write(`${sessionFolder}/results/run-${targetLayer}.json`, JSON.stringify(resultData, null, 2))
+
+// 更新 shared memory
+sharedMemory.execution_results = sharedMemory.execution_results || {}
+sharedMemory.execution_results[targetLayer] = resultData
+sharedMemory.execution_results.pass_rate = passRate
+sharedMemory.execution_results.coverage = coverage
+Write(`${sessionFolder}/shared-memory.json`, JSON.stringify(sharedMemory, null, 2))
+```
+
+### Phase 5: Report to Coordinator
+
+```javascript
+const statusMsg = resultData.all_passed
+  ? `全部通过 (${resultData.tests_passed} tests, 覆盖率 ${coverage}%)`
+  : `${resultData.tests_failed} 个失败 (${iteration}次修复尝试, 覆盖率 ${coverage}%)`
+
+const msgType = resultData.all_passed ? 'tests_passed' : 'tests_failed'
+
+mcp__ccw-tools__team_msg({
+  operation: "log",
+  team: teamName,
+  from: "executor",
+  to: "coordinator",
+  type: msgType,
+  summary: `[executor] ${targetLayer}: ${statusMsg}`,
+  ref: `${sessionFolder}/results/run-${targetLayer}.json`,
+  data: { pass_rate: passRate, coverage, iterations: iteration }
+})
+
+SendMessage({
+  type: "message",
+  recipient: "coordinator",
+  content: `## [executor] Test Execution Results
+
+**Task**: ${task.subject}
+**Layer**: ${targetLayer}
+**Status**: ${resultData.all_passed ? 'PASS' : 'FAIL'}
+**Pass Rate**: ${passRate}%
+**Coverage**: ${coverage}%
+**Iterations**: ${iteration}/${MAX_ITERATIONS}
+
+### Details
+- Tests passed: ${resultData.tests_passed}
+- Tests failed: ${resultData.tests_failed}`,
+  summary: `[executor] QARUN ${targetLayer}: ${resultData.all_passed ? 'PASS' : 'FAIL'} ${passRate}%`
+})
+
+TaskUpdate({ taskId: task.id, status: 'completed' })
+
+const nextTasks = TaskList().filter(t =>
+  t.subject.startsWith('QARUN-') && t.owner === 'executor' &&
+  t.status === 'pending' && t.blockedBy.length === 0
+)
+if (nextTasks.length > 0) { /* back to Phase 1 */ }
+```
+
+## Error Handling
+
+| Scenario | Resolution |
+|----------|------------|
+| No QARUN-* tasks available | Idle, wait for coordinator |
+| Test command fails to execute | Try fallback: `npm test`, `npx vitest run`, `pytest` |
+| Max iterations reached | Report current pass rate, let coordinator decide |
+| Coverage data unavailable | Report 0%, note coverage collection failure |
+| Test environment broken | SendMessage error to coordinator, suggest manual fix |
+| Sub-agent fix introduces new failures | Revert fix, try next failure |
