└────────────────────────────────────────────┘Workflow | 工作流程
1. DISCOVERY - Explore Behavior | 探索行為
Discuss with stakeholders, identify examples and edge cases, understand the "why".
2. FORMULATION - Write Scenarios | 制定場景
Write Gherkin scenarios using ubiquitous language, make them concrete and specific.
3. AUTOMATION - Implement Tests | 自動化測試
Implement step definitions, write minimal code to pass, follow TDD within automation.
4. LIVING DOCUMENTATION - Maintain | 活文件維護
Keep scenarios current, use as shared documentation, review with stakeholders.

Usage | 使用方式
/bdd - Start interactive BDD session | 啟動互動式 BDD 會話
/bdd "user can reset password" - BDD for specific feature | 針對特定功能
/bdd login-feature.feature - Work with existing feature file | 處理現有功能檔案Next Steps Guidance | 下一步引導
After /bdd completes, the AI assistant should suggest:
BDD 場景已定義。建議下一步 / BDD scenarios defined. Suggested next steps: - 執行/tdd實作步驟定義 ⭐ Recommended / 推薦 — Implement step definitions - 執行/checkin品質關卡（若功能完成）— Quality gates (if feature complete) - 與利害關係人審查場景確保業務正確性 — Review scenarios with stakeholders
