Writing effective prompts

All interactions with Claude begin with a prompt, and these prompts, combined with other context, impact Claude’s response. The best approach when speaking to Claude is like you would a coworker—naturally, concisely, and conversationally.

But you may ask, what is a good prompt? Before your next conversation with Claude, consider a few things:

1. Setting the stage: What is your role and what are your objectives? Is there context about your work that Claude should know about?
2. Defining the task: What action do you want Claude to take? Do you want Claude to write, analyze, build, or something else?
3. Specifying rules: What’s the style or tone you want Claude to use? Are there examples that you can attach to show Claude what you’re looking for?

Putting it together

Here’s an example prompt that uses all three elements:

“I’m the marketing lead at an indie streaming startup, and we’re preparing an investor pitch deck for Series A investors. Can you research the current state of the independent film streaming market and identify key trends, competitor positioning, and growth opportunities? Use current web research with citations and structure it as a professional report of up to 5 pages, with an executive summary, market analysis, competitive landscape, and growth opportunities.”

In this prompt:

• Setting the stage: We tell Claude this is for an investor pitch deck for a new indie streaming app—that’s the context and objective.
• Defining the task: We provide the specific action (research the market) with relevant details (trends, competitors, opportunities).
• Specifying rules: We ask for current web research with citations, structured as a professional report—telling Claude exactly what style and format we need.

Want to go deeper? This prompt framework is adapted from the 4D Framework for AI Fluency, developed through research collaboration between Professor Rick Dakan (Ringling College of Art and Design) and Professor Joseph Feller (University College Cork). The framework identifies four core competencies—Delegation, Description, Discernment, and Diligence—that enable effective collaboration with AI.

Adding context

Uploads, connectors, and custom preferences offer ways to give Claude even more context about your work.

Claude can analyze both text and visual elements (like images, charts, and graphics) in PDFs and other documents. Supported file types include PDF, DOCX, CSV, TXT, and common image formats like PNG and JPEG.

Some practical ways to use file uploads:

• Upload a document and ask Claude to summarize the key points
• Share an image and ask Claude to describe or analyze what it sees
• Attach a spreadsheet and ask Claude to identify trends in the data
• Upload code and ask Claude to explain how it works or find bugs

Once uploaded, Claude will automatically attempt to parse the file’s content. In the chat, the file appears as an attachment and you can then prompt Claude about it.

Pro-tip: If you’d like Claude to consider specific preferences in every response, go to Settings > General > ‘What personal preferences should Claude consider?’ to set preferences that apply to every conversation.

Iterating on Claude’s responses

Conversations with Claude are meant to be iterative. Chaining bite-sized prompts together allows for a natural dialogue where you guide the conversation based on Claude’s replies.

If Claude’s first response isn’t quite what you wanted, you have several options:

Ask follow-up questions: Build on Claude’s response by asking for more detail, a different angle, or clarification. For example: “Can you expand on the second point?” or “That’s helpful, but can you make it more concise?”

Provide feedback: Tell Claude what you liked and didn’t like about its response. “This is good, but the tone is too formal. Can you make it more conversational?”

Redirect or restart: If Claude went in a different direction than you intended, simply steer it back. “Actually, I was asking about X, not Y. Let me clarify…“. Worst case, restart your conversation in a new chat to fully refresh the context.

Pro tip: You can also click the pencil icon on any of your messages to edit and resubmit your prompt — useful when you want to refine your request rather than add a new message.

Personalizing Claude

There are two features that help Claude work better for you over time to increase the power of your prompts.

Memory automatically saves key context from your conversations — your role, preferences, past decisions, and working style — so you don’t have to repeat yourself every time you start a new chat. For example, if you tell Claude you work in marketing at a B2B company, it’ll remember that context going forward. You can review, edit, or delete anything Claude remembers anytime in Settings, and memory syncs across all your devices.

Styles let you customize how Claude communicates. Choose from preset options — like concise, formal, or explanatory — or create your own custom style by describing exactly how you want Claude to write. Once set, your style applies across all conversations automatically.
