# Extreme Programming (XP) Practices

<default_to_action>
When applying XP practices:
1. START with practices that give immediate value
2. BUILD supporting practices gradually
3. ADAPT to your context
4. MEASURE results

**Core XP Practices (Prioritized):**
| Practice | Start Here | Why First |
|----------|------------|-----------|
| TDD | ✅ Yes | Foundation for everything |
| Continuous Integration | ✅ Yes | Fast feedback |
| Pair Programming | ✅ Yes | Knowledge sharing |
| Collective Ownership | After CI+TDD | Needs safety net |
| Small Releases | After CI | Infrastructure dependent |

**Pairing Quick Start:**
```
Driver-Navigator (Classic):
- Driver: Writes code
- Navigator: Reviews, thinks ahead
- Rotate every 20-30 min

Ping-Pong (with TDD):
A: Write failing test
B: Make test pass + refactor
B: Write next failing test
A: Make test pass + refactor
```

## Quick Reference Card

### When to Pair

| Context | Pair? | Why |
|---------|-------|-----|
| Complex/risky code | ✅ Always | Needs multiple perspectives |
| New technology | ✅ Always | Learning accelerator |
| Onboarding | ✅ Always | Knowledge transfer |
| Critical bugs | ✅ Always | Two heads better |
| Simple tasks | ❌ Skip | Not worth overhead |
| Research spikes | ❌ Skip | Pair to discuss findings |

## Agent Integration

```typescript
// Agent-human pair testing
const charter = "Test payment edge cases";
const tests = await Task("Generate Tests", { charter }, "qe-test-generator");
const reviewed = await human.review(tests);
await Task("Implement", { tests: reviewed }, "qe-test-generator");

// Continuous integration with agents
await Task("Risk Analysis", { prDiff }, "qe-regression-risk-analyzer");
await Task("Generate Tests", { changes: prDiff }, "qe-test-generator");
await Task("Execute Tests", { scope: 'affected' }, "qe-test-executor");
