XP

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

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)
