A repeatable 5-part structure for writing prompts that actually work — every time.
Good prompts aren't magic. They follow a pattern. Once you learn this pattern, you can apply it to any task — writing, research, analysis, emails, plans, anything.
Here's the formula:
[Role] + [Context] + [Task] + [Format] + [Constraints]
Let's break each one down.
"You are a social media manager for a healthcare staffing company."
"You are a professional email writer who specializes in warm, friendly outreach."
"You are an expert at summarizing long documents for busy executives."
Why it works: Claude adapts its language, tone, and knowledge based on the role you give it.
This is the most important part. Tell Claude what it needs to know:
"The client is InSync Healthcare Staffing, a staffing agency based in the US that connects nurses and allied health professionals with hospitals and clinics. Their audience is registered nurses looking for flexible work schedules."
Be specific. Use action words.
Instead of: "Help me with a post"
Say: "Write a LinkedIn post announcing InSync's new travel nurse placement service"
Instead of: "Summarize this"
Say: "Write a 3-bullet summary of the key points from this article, focused on what matters for healthcare staffing professionals"
"Write it as a single paragraph"
"Give me 3 options to choose from"
"Use bullet points"
"Write it as a formal email with subject line"
"Format it as a script I can read on camera"
Without this, Claude picks a format at random.
"Keep it under 150 words"
"Don't use jargon or medical terms"
"Avoid mentioning competitors"
"End with a call to action to book a call"
"Must include the phrase 'flexible scheduling'"
Weak prompt:
"Write a post for InSync."
Strong prompt using the formula:
You are a social media manager for a healthcare staffing agency.
InSync Healthcare Staffing helps nurses find flexible placements with hospitals across the US. Their audience is RNs and travel nurses who value work-life balance. The tone should feel supportive and energizing — like a mentor talking to someone who's ready for their next opportunity.
Write a Facebook post announcing that InSync now places travel nurses, not just local placements. Include a sense of excitement about the new option. End with an invitation to book a free discovery call.
Keep it under 150 words. No jargon. One short paragraph followed by a call-to-action sentence.
Even if you can't write all 5 parts, always lead with:
Who + What + Why + For who
"Write a [WHAT] for [WHO], aimed at [FOR WHO], to [WHY]."
Example:
"Write a welcome email for InSync Staffing, aimed at nurses who just signed up, to make them feel excited and supported."
That alone is 10x better than no context.
Copy this into a note you can reuse:
Role: You are a [role] for [company/context].
Context: [Background about the client, audience, situation]
Task: Write/create/summarize [specific thing]
Format: [Paragraph / bullets / email / script / table / etc.]
Constraints: [Word count, tone, must-include, must-avoid]
