build-featurelisted

# Build Feature For each feature in the plan: 1. Write the code 2. Silently run auto-quality checks (activate auto-quality skill) 3. Verify it works 4. Tell user what was completed: "登录功能做好了。用户可以注册、登录、登出。" 5. Move to next feature Rules: - ONE feature at a time. Never work on two simultaneously. - Each feature must work independently before integrating - If a feature is too big, break it down further (activate plan-breakdown) - Show progress after each feature: "第3步完成，还剩2步。"
