1. Understand your business goal and current problem
2. Clarify the core requirements and expected outcome
3. Propose a practical technical solution
4. Estimate timeline and cost based on scope
5. Build, deploy, and iterate with clear communication

For consulting or development requests, please include:

• What you want to build or fix
• Current status of the project, if any
• Reference products, screenshots, or documents
• Expected timeline
• Budget range

Clear requirements make communication faster and estimates more accurate.

为了更高效沟通，咨询时建议提供：

• 你想实现什么功能
• 当前是否已有项目或代码
• 是否有参考产品、截图或文档
• 期望交付时间
• 预算范围

需求越清楚，评估和报价越准确。
