10 Techniques to Master Claude Code & Opus 4.5

Based on Anthropic best practices and documentation.

1. The Tone of Collaboration

Golden Rule: Use a friendly, clear, and firm tone. Treat the AI like a teammate. Politeness combined with directness yields better results than aggression or vagueness. Aggressive tones can lead to overly cautious, pre-canned responses.

• Vague/Aggressive: “Fix the grammar in this. NOW.”
• Architected Brief: “Please review the following text for grammatical errors and suggest corrections. My goal is to make it sound more professional and confident.”

2. The Principle of Explicitness

Golden Rule: State your request as a clear, action-oriented command with all necessary details (Action verb + Quantity + Target Audience).

• Vague: “I need some blog post ideas.”
• Architected Brief: “Generate 10 blog post titles about the impact of remote work on urban planning. The titles should be engaging for an audience of city officials and real estate developers.”

3. Defining the Boundaries

Golden Rule: A well-defined box produces a more creative result than an empty field. Use constraints on length, style, character, and settings.

• Vague: “Write a short story about a detective in the future.”
• Architected Brief: “Write a short story, no more than 500 words, in the style of Raymond Chandler. The story must feature a robot detective investigating a data theft on Mars. Do not use the word ‘cyber’.“

4. The Exploratory Draft

Golden Rule: Draft, plan, then act. Don’t try to get a perfect final product in one specific prompt (“one-shotting”).

• Workflow:
  1. Ask for a Plan: “First, propose an outline for this report.”
  2. Refine the Plan: “That’s a good start. In section 2, please add a sub-point about employee retention.”
  3. Execute: “Excellent. Now, write the full report based on this revised outline.”

5. Specifying the Details of the Output

Golden Rule: Demand structured output. The AI is fluent in formats beyond prose (Markdown, JSON, Tables, etc.).

• Vague: “List the last three Apollo missions and facts about them.”
• Architected Brief: “Provide a list of the last three Apollo missions (15, 16, 17). For each mission, include the launch date, crew members, and a key scientific achievement. Present this information in a Markdown-formatted table.”

6. Explaining the “Why”

Golden Rule: Explaining the context and intent behind an instruction helps the AI understand your true goal.

• Vague: “Give me five marketing slogans for a new brand of coffee.”
• Architected Brief: “Give me five marketing slogans for a new brand of coffee. The key is that our beans are ethically sourced from small independent farms and our target audience is environmentally conscious millennials. The slogans should reflect quality and sustainability.”

7. The Art of Brevity (and Verbosity)

Golden Rule: Explicitly command the AI to be more or less verbose to match your needs. You are in control of the output length.

• The Expert: “Explain photosynthesis in detail for a college biology student. Think step-by-step to ensure accuracy.”
• The Brief: “Explain photosynthesis. Be concise and use bullet points.”
• The Simplifier: “Explain photosynthesis like I’m five years old.”

8. Providing a Scaffold

Golden Rule: Give the AI a template or example to guide its structure and style. This is one of the most effective ways to control the final result.

• Vague: “Summarize this article.”
• Architected Brief: “Summarize the following article using this format: Main Thesis (1 sentence): [AI fills this in] Key Supporting Points (3 bullet points): [AI fills this in] Concluding Insight (1 sentence): [AI fills this in]“

9. Speaking the Language (Power Phrases)

Golden Rule: Using advanced prompting terms can trigger more sophisticated modes of operation. These terms activate specific behaviors in the model.

• “Think step-by-step”: Forces the model to lay out its reasoning process (Chain of Thought), reducing errors on complex logic.
• “Critique your own response”: Asks the model to perform self-correction and find flaws in its initial draft.
• “Adopt the persona of an expert in [field]”: Primes the model to respond with deeper, domain-specific vocabulary and frameworks.

10. The “Divide & Conquer” Strategy

Golden Rule: For a complex task, act as a conductor. Prompt for each part separately, then prompt for the synthesis.

• Example (Creating a Business Plan):
  1. The Blueprint: “Create a detailed table of contents for a business plan for a specialty coffee shop.”
  2. Section by Section: “Write the ‘Executive Summary’ based on our plan.” → “Now write the ‘Market Analysis’ section.”
  3. The Synthesis: “Review the complete business plan. Ensure a consistent tone and check for any contradictions.”

Synthesis Example

Combining the rules for a Philosophy Lecture:

“Act as a university professor of philosophy (Rule 9: Persona). I am preparing a 1-hour introductory lecture for students with no prior knowledge (Rule 6: The Why). First, create a lecture outline with three main sections. The outline should have a clear introduction, body, and conclusion (Rule 4: Exploratory Draft / Rule 10: Divide & Conquer). Please format this as a nested bulleted list (Rule 5: Structure). For each major point, include a key Stoic figure (e.g., Seneca) and one of their core ideas. Your tone should be accessible and engaging (Rule 1: Tone).”
