The fastest way to get comfortable with Claude isn't reading about prompting - it's running a handful of prompts that show you what it can actually do. Here are ten worth trying in your first week, roughly in order of how much they'll teach you.
1. The "explain it to me" prompt
"Explain [topic] like I'm smart but new to this." Try it with something from your job. Notice how it adjusts depth based on how you phrase the request.
2. The rewrite
Paste a clumsy email or message you wrote and ask: "Rewrite this to sound more confident, keep it under 100 words." This is the single highest-value habit most people build first.
3. The structured summary
Paste a long article or report and ask for "a 5-bullet summary, then a one-sentence takeaway." You'll see how well Claude compresses information without losing the point.
4. The devil's advocate
Describe a decision you're weighing and ask Claude to argue the other side. This is one of the most underused prompts - it's a free sounding board that doesn't get tired of disagreeing with you.
5. The step-by-step plan
"I need to [goal]. Give me a step-by-step plan, and flag anything that could go wrong." Good for anything from a product launch to reorganizing a closet.
6. The role-based answer
"Answer this as a skeptical CFO would" or "as a first-time user would." Framing who's answering changes the answer more than you'd expect.
7. The format constraint
Ask for the same information as a table, then as three bullet points, then as a two-line summary. This teaches you that Claude's output format is something you control, not something fixed.
8. The "what am I missing" prompt
Share a plan or draft and ask: "What am I missing? What would an expert critique here?" Genuinely useful before you ship anything important.
9. The follow-up
Don't start a new chat for your next question - reply in the same thread with "now make it shorter" or "now do the same for X." Claude remembers the conversation, and building on previous answers is faster than starting fresh each time.
10. The honest self-check
Ask Claude to grade its own answer: "Rate your last response 1-10 for accuracy and tell me what you're least sure about." It's surprisingly good at flagging its own uncertainty when asked directly.
