With the release of Claude 4 (including Opus 4 and Sonnet 4), AI dialog technology has reached new heights 📈. However, to fully utilize the capabilities of Claude 4, it becomes crucial to master effective prompt word engineering techniques 🔑. In this article, we will delve into how to communicate efficiently with Claude 4 to bring your AI interaction experience to a professional-grade level ⭐.

Understand the core features and communication preferences of Claude 4 🧠

Claude 4 demonstrates a greater ability to follow instructions than its predecessor, but it has also become more "precise" - it will follow your instructions to the letter without overplaying them 🎯. This change required us to adjust the way we communicate with the AI.

Key features of Claude 4 ✨

These characteristics mean that we need to employ more structured and explicit communication strategies 📋.

Core Strategies for Building Effective Prompt Words 💡

Principle of precision: tell Claude exactly what to do 🔧

Vague instructions are the root cause of ineffective conversations ❌.Claude 4 needs clear, specific instructions from you.

❌ Expressions to avoid:

• "Help me make a website."
• "Analyze these data."
• "Write something."

✅ Recommended expression:

• "Please create a responsive official corporate homepage with navigation bar, rotating images, product showcase area and contact form using modern minimalist style 🎨"
• "Please perform a year-over-year analysis of this sales data, focusing on quarterly trend changes, and generate a visual chart 📊"
• "Write a 1500-word technical blog on Machine Learning in Financial Risk Control for IT practitioners 💻"

Context-rich strategies: why is more important than what 🌟

Providing task context can significantly improve Claude's performance 📈. When Claude understands the purpose and context of a task, it can make more appropriate decisions.

📝 Context provides the template:

🎯 Task Goal: [what specifically is to be accomplished]
🏢 Scenarios of Use: [under what circumstances will it be used]
👥 Target Audience: [Who will see/use this result]
💫 Desired effect: [what impact is desired]
⚠️ Constraints: [what are the limitations or requirements]

🔥 Examples of practical applications:

"I need to design a React component library introduction document for new hire training 📚. This is to help new front-end developers get up to speed quickly with our component system 🚀. The documentation needed to be concise and easy to understand, containing code examples and best practices, as newcomers often make mistakes with component usage specifications ⚡."

Example-driven learning: showing is worth a thousand words 💎

Claude has excellent mimicry skills and a good example is often more effective than a long explanation 🎪.

📌 Example design points:

• ✨ Demonstrate desired format and style
• 🔗 Contains complete input-output correspondences
• 🚫 Avoid including elements that you don't want to be parodied
• 🎲 Provide diverse examples to avoid overfitting

Advanced control techniques and best practices ⚡

Precise control of the output format 🎛️

Claude 4 responds well to formatting commands, but requires the use of positive expressions ➕.

Please wrap your analysis in  tags to ensure that the content is clearly structured and easy to read 📖.

Activate thinking and planning skills 🧭

Claude 4 has powerful multi-step reasoning capabilities, and reasonable guidance can significantly improve the quality of completion of complex tasks 🔮.

💭 Think about activating the prompt words:

Before beginning a task, analyze the need, develop a plan, and then implement it step-by-step 📋. After each key step, evaluate current progress and decide on the best follow-up 🎯.

🎪 Applicable Scenarios:

• 📊 Data analysis projects (cleansing → exploration → modeling → visualization)
• 💻 Software development tasks (requirements analysis → design → coding → testing)
• ✍️ Content Creation (Research → Outlining → Writing → Optimization)

Parallel processing optimization ⚡

For complex projects involving multiple independent subtasks, explicit guidance on parallel processing can dramatically improve efficiency 🚀.

🔄 Parallel Processing Guidelines:

For efficiency ⚡ When presented with separate tasks that can be performed simultaneously, perform them in parallel instead of processing them sequentially 🎯.

🎯 Typical application scenarios:

• 📁 Multi-file data processing
• 📈 Multidimensional analysis report
• 🧩 Multi-component front-end development

Common Challenges and Solutions 🛠️

The Problem of Overconservatism ⚠️

❗ Problem manifestation: Claude 4 can be overly cautious at times, with output that is simpler or more conservative than expected.

💡 Solution Strategy:

• 🎉 Use encouraging language: "Please show your full capacity"
• 🎨 Explicit requirement for complexity: "Include as many features and details as possible"
• 🏆 Setting a Challenge Goal: "This program needs to show professionalism"

Temporary file management 📁

❗ Problem manifestation: Too many intermediate files may be generated during tasks such as code generation.

🧹 Solution Strategy:

Please clean up any temporary files created for testing or intermediate processing after completing major tasks to keep your work environment tidy ✨.

Front-end development quality improvement 🎨

🚀 Enhance the cue word:

Please create a fully functional and visually beautiful modern interface 💎 that contains:
- ✨ Fluid transition animations and micro-interactions
- 📱 Responsive design and mobile adaptation
- 🎯 Hover effects and status feedback
- 🎨 Follows current design trends and UX best practices

Real-world application guides and advanced tips 🎯

Highlights of the migration from Claude 3.5 🔄
