14. Claude 4.6 Tips

---

1. Be Explicit and Detailed

Claude doesn’t fill in the blanks. If your prompt is vague, you’ll get vague results. Write clear, detailed instructions.

Less effective:

Summarize this document

More effective:

Summarize this 20-page market research report for executives. Keep the summary under 300 words, highlight 3 key insights, and avoid technical jargon. Format the output as bullet points for a slide deck.

Tip: Add modifiers like “concise,” “detailed,” “executive-friendly,” or “slide-ready” to shape the result you want.

---

2. Add Context for Clarity

Claude works best when it knows why you need the result and who it’s for. Rules alone aren’t enough. Explain the purpose.

Less effective:

Never use ellipses

More effective:

Your response will be read aloud by a text-to-speech system, so never use ellipses. The system cannot pronounce them and it will disrupt the flow.

When possible, include:

• Purpose (e.g., “internal research for Q4 planning”)

• Audience (e.g., “executives with no technical background”)

• Workflow (e.g., “feeds into a presentation deck”)

• Success criteria (e.g., “summary under 300 words, free of jargon”)

---

3. Assign a Role

A simple role can focus Claude’s voice and judgment. This is especially helpful when you want the output to match a specific audience or job function.

Example:

Act as a research analyst writing for senior leadership.
Your job is to surface the most decision-relevant insights,keep the tone factual, 
and avoid unnecessary technical detail.

---

4. Give Step-by-Step Instructions

Breaking tasks into steps helps Claude follow complex requests more reliably. Instead of bundling everything, spell it out.

Unclear prompt:

Summarize this 20-page report

Clear prompt with steps:

Task: Summarize this 20-page market research report for executives.
Steps:
1. Identify the 3 most important insights
2. Remove all technical jargon and use plain language
3. Keep the entire summary under 300 words
4. Format the result as bullet points for a slide deck

---

5. Structure Complex Prompts with XML Tags

Claude handles structured prompts especially well. XML-style tags make different parts of the prompt easier to separate and reduce ambiguity.

Example:

<context>
Board presentation for executives with
no technical background.
</context>
<instructions>
Summarize the report into 3 bullets.
Remove jargon.
</instructions>
<input>
[Paste report here]
</input>
<output_format>
Exactly 3 bullets. No intro. No
conclusion.
</output_format>

Clear prompt with steps:

• <context>

• <instructions>

• <input>

• <examples>

• <output_format>

---

6. Use Examples

Examples are one of the strongest ways to steer Claude’s tone, structure, and formatting. If the output needs to look a certain way, show Claude what “good” looks like.

Tip:

Use 3–5 short examples when consistency matters. Keep them high quality, clearly relevant, and aligned to the exact output you want.

<examples>
 <example>
 Input: Summarize this report for
executives.
 Output: 3 short bullets, plain
language, no jargon.
 </example>
 <example>
 Input: Summarize this issue update
for leadership.
 Output: 3 bullets plus 1 risk
note, concise and factual.
 </example>
</examples>

7. Use Claude’s “Thinking” Mode

Claude 4 can pause and reflect before giving its final output. This makes it especially strong for reviewing documents or complex reasoning.

Prompt idea:

After reading the report, reflect on the key themes before writing the summary. Double-check that the final version is clear, jargon-free, and under 300 words.

This approach works well for:

• Reviewing lengthy reports before drafting summaries

• Iterating on a first draft for clarity

• Comparing multiple sources and extracting common themes

---

8. Prompt Well for Long Documents

For long-context tasks, structure matters. Put long documents near the top, place the main question near the end, and tell Claude how to process the material.

• If you have multiple documents, label them clearly.

• Ask Claude to quote or extract the most relevant passages first when accuracy matters.

• Tell Claude exactly what to synthesize, compare, or prioritize

---

9. Run Through a Quick Checklist

Before sending your prompt, ask yourself:

• Did I specify the purpose, audience, workflow, and success criteria?

• Did I clearly state what to include and what to avoid?

• Did I break complex instructions into steps?

• Did I add quality modifiers (“concise,” “executive-ready,” etc.)?

• Do I want Claude to reflect before finalizing the output?

This five-second check can turn a weak summary into a strong one.

10. Task-Oriented Prompt Template

Use this when you need Claude to produce a clear, finished output.

Context: [Where this will be used, who the audience is]
Task: [Exactly what you want Claude to do; add modifiers like “executive-friendly,” “concise,” etc.]
Steps:
1. [Step one]
2. [Step two]
3. [Step three]
Constraints: [Tone, format, length, what to avoid]
Optional: Ask Claude to reflect and refine before finalizing

Example:

Context: Board presentation for executives with no technical background
Task: Summarize this 20-page market research report into 3 clear slides
Steps:
1. Identify the 3 most important findings
2. Remove all technical jargon
3. Keep each slide under 40 words
Constraints: Output only the 3 slides, no introduction or conclusion

---

11. Instruction and Reason Template

When formatting or rules matter, tell Claude the reason. It follows rules more reliably when it understands the “why.”

Task: Do not use ellipses (…) in your response
Reason: The text will be read aloud by a text-to-speech system, which cannot pronounce ellipses

This is useful for tone, formatting, or compliance requirements.

---

12) Step-by-Step Workflow Template

For multi-step work (like processing or transforming documents), give Claude a workflow.

Task: [Overall goal]
Instructions:
1. [Step one]
2. [Step two]
3. [Step three]
Final Output: [Exact format you want]

Example:

Task: Process customer survey responses for quarterly review
Instructions:
1. Anonymize all personal information (names, emails, phone numbers)
2. Extract the top 5 recurring themes
3. Summarize each theme in 2 sentences
Final Output: Show only the anonymized themes, formatted as bullet points

14) Claude 4.6 Tips

1. Control verbosity more deliberately: Claude 4.6 is generally more concise, direct, and efficient than older Claude models. If you want status updates, summaries after tool calls, or more visible reasoning steps, ask for them explicitly.

2. Guard against overengineering: Claude Opus 4.6 can sometimes overbuild by adding extra files, abstractions, flexibility, or polish that was not requested. Add constraints like “keep the solution minimal” or “do not add extra structure unless required.”

3. Be explicit when you want action, not suggestions: Claude 4.6 may follow your wording literally. If you ask it to “suggest edits,” it may only propose changes.

4. Use Positive Steering: Tell Claude what to do rather than what not to do (e.g., "Use flowing prose" instead of "Do not use bullet points").

Final Tip

With Claude, clarity beats cleverness. Don’t just say “summarize”. Tell it how long, for whom, and in what format. That’s how you turn a 20-page report into something useful in minutes.
