+description: 强制执行测试驱动开发工作流。首先搭建接口，生成测试，然后实现最小化代码以通过测试。确保 80%+ 覆盖率。
+---
+
+# TDD 命令
+
+此命令调用 **tdd-guide** 代理来强制执行测试驱动开发方法。
+
+## 此命令的作用
+
+1. **搭建接口** - 首先定义类型/接口
+2. **首先生成测试** - 编写失败的测试（红）
+3. **实现最小化代码** - 编写刚好足够的代码以通过测试（绿）
+4. **重构** - 改进代码，同时保持测试通过（重构）
+5. **验证覆盖率** - 确保 80%+ 的测试覆盖率
+
+## 何时使用
+
+在以下情况下使用 `/tdd`：
+
+* 实现新功能时
+* 添加新函数/组件时
+* 修复错误时（首先编写重现错误的测试）
+* 重构现有代码时
+* 构建关键业务逻辑时
+
+## 工作原理
+
+tdd-guide 代理将：
+
+1. 为输入/输出**定义接口**
+2. **编写将会失败的测试**（因为代码尚不存在）
+3. **运行测试**并验证它们因正确的原因而失败
+4. **编写最小化实现**以使测试通过
+5. **运行测试**并验证它们通过
+6. **重构**代码，同时保持测试通过
+7. **检查覆盖率**，如果低于 80% 则添加更多测试
+
+## TDD 循环
+
+```
+RED → GREEN → REFACTOR → REPEAT
+
+RED:      Write a failing test
+GREEN:    Write minimal code to pass
+REFACTOR: Improve code, keep tests passing
+REPEAT:   Next feature/scenario
+```
+
+## 使用示例
+
+````
+User: /tdd I need a function to calculate market liquidity score
+
+Agent (tdd-guide):
+# TDD Session: Market Liquidity Score Calculator
+
+## Step 1: Define Interface (SCAFFOLD)
+
+```typescript
+// lib/liquidity.ts
+export interface MarketData {
+  totalVolume: number
+  bidAskSpread: number
+  activeTraders: number
+  lastTradeTime: Date
+}
+
+export function calculateLiquidityScore(market: MarketData): number {
+  // TODO: Implementation
+  throw new Error('Not implemented')
+}
+````
+
+## 步骤 2：编写失败的测试（红）
+
+```typescript
+// lib/liquidity.test.ts
+import { calculateLiquidityScore } from './liquidity'
+
+describe('calculateLiquidityScore', () => {
+  it('should return high score for liquid market', () => {
+    const market = {
+      totalVolume: 100000,
+      bidAskSpread: 0.01,
+      activeTraders: 500,
+      lastTradeTime: new Date()
+    }
+
+    const score = calculateLiquidityScore(market)
+
+    expect(score).toBeGreaterThan(80)
+    expect(score).toBeLessThanOrEqual(100)
+  })
+
+  it('should return low score for illiquid market', () => {
+    const market = {
+      totalVolume: 100,
+      bidAskSpread: 0.5,
+      activeTraders: 2,
+      lastTradeTime: new Date(Date.now() - 86400000) // 1 day ago
+    }
+
+    const score = calculateLiquidityScore(market)
+
+    expect(score).toBeLessThan(30)
+    expect(score).toBeGreaterThanOrEqual(0)
+  })
+
+  it('should handle edge case: zero volume', () => {
+    const market = {
+      totalVolume: 0,
+      bidAskSpread: 0,
+      activeTraders: 0,
+      lastTradeTime: new Date()
+    }
+
+    const score = calculateLiquidityScore(market)
+
+    expect(score).toBe(0)
+  })
+})
+```
+
+## 步骤 3：运行测试 - 验证失败
+
+```bash
+npm test lib/liquidity.test.ts
+
+FAIL lib/liquidity.test.ts
+  ✕ should return high score for liquid market (2 ms)
+    Error: Not implemented
+
+1 test failed, 0 passed
+```
+
+✅ 测试按预期失败。准备实施。
+
+## 步骤 4：实现最小化代码（绿）
+
+```typescript
+// lib/liquidity.ts
+export function calculateLiquidityScore(market: MarketData): number {
+  // Handle zero volume edge case
+  if (market.totalVolume === 0) {
+    return 0
+  }
+
+  // Calculate component scores (0-100 scale)
+  const volumeScore = Math.min(market.totalVolume / 1000, 100)
+  const spreadScore = Math.max(100 - (market.bidAskSpread * 1000), 0)
+  const traderScore = Math.min(market.activeTraders / 10, 100)
+
+  // Recent activity bonus
+  const hoursSinceLastTrade = (Date.now() - market.lastTradeTime.getTime()) / (1000 * 60 * 60)
+  const recencyScore = Math.max(100 - (hoursSinceLastTrade * 10), 0)
+
+  // Weighted average
+  const score = (
+    volumeScore * 0.4 +
+    spreadScore * 0.3 +
+    traderScore * 0.2 +
+    recencyScore * 0.1
+  )
+
+  return Math.min(Math.max(score, 0), 100) // Clamp to 0-100
+}
+```
+
+## 步骤 5：运行测试 - 验证通过
+
+```bash
+npm test lib/liquidity.test.ts
+
+PASS lib/liquidity.test.ts
+  ✓ should return high score for liquid market (3 ms)
+  ✓ should return low score for illiquid market (2 ms)
+  ✓ should handle edge case: zero volume (1 ms)
+
+3 tests passed
+```
+
+✅ 所有测试通过！
+
+## 步骤 6：重构（改进）
+
+```typescript
+// lib/liquidity.ts - Refactored with constants and better readability
+const WEIGHTS = {
+  VOLUME: 0.4,
+  SPREAD: 0.3,
+  TRADERS: 0.2,
+  RECENCY: 0.1,
+} as const
+
+const SCALE_FACTORS = {
+  VOLUME: 1000,
+  SPREAD: 1000,
+  TRADERS: 10,
+  RECENCY_PENALTY: 10,
+} as const
+
+function clamp(value: number, min: number, max: number): number {
+  return Math.min(Math.max(value, min), max)
+}
+
+export function calculateLiquidityScore(market: MarketData): number {
+  if (market.totalVolume === 0) return 0
+
+  const volumeScore = Math.min(market.totalVolume / SCALE_FACTORS.VOLUME, 100)
+  const spreadScore = clamp(100 - (market.bidAskSpread * SCALE_FACTORS.SPREAD), 0, 100)
+  const traderScore = Math.min(market.activeTraders / SCALE_FACTORS.TRADERS, 100)
+
+  const hoursSinceLastTrade = (Date.now() - market.lastTradeTime.getTime()) / (1000 * 60 * 60)
+  const recencyScore = clamp(100 - (hoursSinceLastTrade * SCALE_FACTORS.RECENCY_PENALTY), 0, 100)
+
+  const weightedScore =
+    volumeScore * WEIGHTS.VOLUME +
+    spreadScore * WEIGHTS.SPREAD +
+    traderScore * WEIGHTS.TRADERS +
+    recencyScore * WEIGHTS.RECENCY
+
+  return clamp(weightedScore, 0, 100)
+}
+```
+
+## 步骤 7：验证测试仍然通过
+
+```bash
+npm test lib/liquidity.test.ts
+
+PASS lib/liquidity.test.ts
+  ✓ should return high score for liquid market (3 ms)
+  ✓ should return low score for illiquid market (2 ms)
+  ✓ should handle edge case: zero volume (1 ms)
+
+3 tests passed
+```
+
+✅ 重构完成，测试仍然通过！
+
+## 步骤 8：检查覆盖率
+
+```bash
+npm test -- --coverage lib/liquidity.test.ts
+
+File           | % Stmts | % Branch | % Funcs | % Lines
+---------------|---------|----------|---------|--------
+liquidity.ts   |   100   |   100    |   100   |   100
+
+Coverage: 100% ✅ (Target: 80%)
+```
+
+✅ TDD 会话完成！
+
+```
+
+## TDD Best Practices
+
+**DO:**
+- ✅ Write the test FIRST, before any implementation
+- ✅ Run tests and verify they FAIL before implementing
+- ✅ Write minimal code to make tests pass
+- ✅ Refactor only after tests are green
+- ✅ Add edge cases and error scenarios
+- ✅ Aim for 80%+ coverage (100% for critical code)
+
+**DON'T:**
+- ❌ Write implementation before tests
+- ❌ Skip running tests after each change
+- ❌ Write too much code at once
+- ❌ Ignore failing tests
+- ❌ Test implementation details (test behavior)
+- ❌ Mock everything (prefer integration tests)
+
+## Test Types to Include
+
+**Unit Tests** (Function-level):
+- Happy path scenarios
+- Edge cases (empty, null, max values)
+- Error conditions
+- Boundary values
+
+**Integration Tests** (Component-level):
+- API endpoints
+- Database operations
+- External service calls
+- React components with hooks
+
+**E2E Tests** (use `/e2e` command):
+- Critical user flows
+- Multi-step processes
+- Full stack integration
+
+## Coverage Requirements
+
+- **80% minimum** for all code
+- **100% required** for:
+  - Financial calculations
+  - Authentication logic
+  - Security-critical code
+  - Core business logic
+
+## Important Notes
+
+**MANDATORY**: Tests must be written BEFORE implementation. The TDD cycle is:
+
+1. **RED** - Write failing test
+2. **GREEN** - Implement to pass
+3. **REFACTOR** - Improve code
+
+Never skip the RED phase. Never write code before tests.
+
+## Integration with Other Commands
+
+- Use `/plan` first to understand what to build
+- Use `/tdd` to implement with tests
+- Use `/build-fix` if build errors occur
+- Use `/code-review` to review implementation
+- Use `/test-coverage` to verify coverage
