description	Extreme Programming workflow orchestrator. Use when implementing features. Coordinates planning, TDD, refactoring, and commits.

Extreme Programming Workflow

Overview

This skill orchestrates the full XP workflow for feature implementation. It coordinates sub-skills and ensures proper sequencing of phases.

The XP Workflow

┌─────────────────────────────────────────────────────────────┐
│  📋 PLAN     → Discuss and break down the feature          │
│  🔴 DEVELOP  → TDD cycle (red-green)                       │
│  🔵 REFACTOR → Improve design (tests stay green)           │
│  💾 COMMIT   → Save working state                          │
│  🔁 ITERATE  → Next task or feature complete              │
└─────────────────────────────────────────────────────────────┘

Phase 1: Planning (📋 PLAN)

Goal: Understand and decompose the feature before writing any code.

Invoke: Switch to planning skill

---

Phase 2: Development (🔴 DEVELOP)

Goal: Implement the task using strict TDD.

Invoke: Switch to development skill

---

Phase 3: Refactoring (🔵 REFACTOR)

Goal: Improve code design while keeping tests green.

1. Invoke: Switch to refactor skill
2. STOP
   • Ask the user if they want to see any other changes
3. Ensure all tests pass before continuing

---

Phase 4: Commit (💾 COMMIT)

Goal: Save working state with clear, simple, commit message.

Invoke: Switch to commit-helper skill

Commit Points

• After each passing test
• After completing a task
• After refactoring session

---

Phase 5: Iterate (🔁 ITERATE)

Goal: Continue until feature complete.

1. Mark task as done
2. Review remaining tasks
3. Adjust plan if needed (new learnings)
4. Return to Phase 2 for next task
5. When all tasks complete → feature done

---

Announcing Phase Transitions

When switching phases, announce clearly:

📋 PLAN → Starting feature discussion
🔴 DEVELOP → Writing failing test for [task]
🟢 DEVELOP → Making test pass
🔵 REFACTOR → Improving [aspect]
💾 COMMIT → Saving [task] implementation
🔁 ITERATE → Moving to next task
✅ COMPLETE → Feature done

Integration with Sub-Skills

Phase	Skill
PLAN	planning
DEVELOP	development
REFACTOR	refactor
COMMIT	commit-helper

Core Principles (Always Apply)

• Communication first — discuss before coding
• Small steps — one task, one test, one change at a time
• Continuous feedback — tests run constantly
• Simplicity — implement only what's needed now
• Courage — refactor fearlessly (tests protect you)
