Claude 高阶使用指南

Claude has been out for two years. Most people who use it every day are still using 10% of what it can do. Not because it's complicated. Because nobody showed them what the other 90% looks like. This guide fixes that. By the end you will have Claude set up in a way that remembers you, understands you, and works the way you actually think. And you will know how to use it for things most people have never tried. Start Here 1 - Create a Project, not a chat Every time you open a new Claude chat, it starts with zero memory. It doesn't know your name, your work, your goals, or how you like to communicate. You spend the first few messages re-explaining yourself, or you don't, and Claude gives you something generic that doesn't fit how you actually work. Projects fix this. A Project is a persistent workspace where Claude keeps context across every conversation inside it. You set it up once and every session that follows starts with Claude already knowing who you are. Go to Claude, click Projects in the sidebar, and create a new one. Name it something like "Work" or "Personal" depending on how you plan to use it. Everything that follows goes inside this Project. 2 - Tell Claude who you are Before Claude can help you well, it needs to understand you. Most people skip this step entirely and wonder why Claude gives them answers that feel slightly off. Paste this into your Project and fill in every field honestly. The more specific you are, the better every single response becomes. Save this inside your Project's knowledge base. Claude will read it at the start of every conversation in this Project. 3 - Turn that into Custom Instructions Pasting your background is a good start. But Custom Instructions go further. They tell Claude not just who you are, but exactly how to behave with you by default.

Paste this prompt into Claude after you've filled in the template above: Take the output and paste it into your Project Instructions. This becomes Claude's permanent operating mode for every conversation in this Project. Claude Is Not What You Think 4 - Claude is not a search engine Most people use Claude the way they use Google. They type a question and wait for an answer. That is the lowest-value way to use it. Claude is not a retrieval tool. It is a thinking partner. It doesn't just pull information, it reasons, synthesizes, argues, and builds on context. The moment you treat it like a search engine, you cut its usefulness by 80 percent. Stop asking Claude what something is. Start asking Claude to help you think through something. Instead of: "What is prompt caching?" Try: "I'm building a workflow that calls Claude 20 times per session. Walk me through how prompt caching works and whether it would actually reduce my costs given that context." The second prompt gives Claude a problem to solve with you. The first gives it a definition to recite. 5 - Ask Claude to ask you questions first This is one of the most powerful techniques almost nobody uses. Before Claude starts any complex task, tell it to gather information from you first. When Claude asks you questions before starting, the output is dramatically better because it's built on the right foundation. Without this, Claude makes assumptions and you spend time correcting things that could have been right the first time. Use this before any important task: Or for a specific task: What Even Regular Users Don't Know 6 - Style cloning When Claude writes in your voice without examples, it writes in its own voice. The output is grammatically correct and completely wrong in tone. It sounds like AI because it is. Give Claude three to five samples of your own writing. Ask it to analyze your patterns, not just describe your style. After that analysis, it writes like you, not like a polished corporate assistant. 7 - Claude as your sparring partner Most people ask Claude to help them with ideas. That means Claude builds on what you say, adds to it, expands it. You get agreement and elaboration. That is useful sometimes. But it is not how you stress-test an idea. Before committing to any plan, decision, or piece of writing, ask Claude to attack it. Not critique it. Attack it. The distinction matters. 8 - Extended Thinking Most Claude users have never turned this on. Extended Thinking is a mode where Claude reasons through a problem step by step before giving you an answer, instead of going straight to the output. For simple tasks, you don't need it. For complex decisions, analysis, or any question where you want Claude to actually think rather than pattern-match, turn it on. In Claude, click the brain icon before sending your message. Or add this to your prompt: The difference in output quality on hard questions is significant. 9 - Claude writes prompts for Claude This is the most underused thing you can do. If you're not sure how to prompt Claude for a specific task, ask Claude to write the prompt for you. Claude knows what kinds of instructions produce better results. Let it use that knowledge on your behalf. How to Spend Fewer Tokens and Get More 10 - Specify the output length Claude's default is to write as much as it thinks is appropriate That is usually more than you need, which means more tokens used, more time spent reading, and more noise in the output. Tell Claude exactly how long you want the answer before it starts. This one instruction cuts token usage on most tasks by 40 to 60 percent without losing any of the value you actually need. 11 - Remove the preamble Every Claude response defaults to starting with something you didn't ask for. "Great question. Let me break this down for you." Or a full restatement of what you just said. Or a disclaimer. Or a closing summary that repeats everything it just told you. You didn't ask for any of that. It costs tokens and it wastes your time. Add this to your Custom Instructions: 12 - Don't re-explain yourself every conversation If you're pasting the same background information into every new chat, you are wasting tokens every single time and training yourself into a habit that costs you more as Claude usage scales. This is exactly what Projects and Custom Instructions are for. Put your context in once. Let Claude read it automatically at the start of every session. Never paste your background again. If you are not using Projects yet, start there before anything else in this article. 13 - Start a new chat for a new topic Claude carries the context of everything said earlier in a conversation. When you switch topics inside a long chat, Claude still has all the previous context loaded. That means more tokens used on every response, slower processing, and context bleed from earlier in the conversation affecting your new topic. When you switch to something unrelated, start a fresh chat inside your Project. You keep the Project memory. You lose the irrelevant baggage. Ready to Use Right Now These are complete prompts you can copy and use immediately. 14 - Understand anything through analogies (Feynman method) Most explanations Claude gives by default are technically correct and practically useless. They use the same vocabulary as the thing you're trying to understand, which means you walk away with a definition but not actual comprehension. The Feynman method forces understanding through simplicity. If Claude can't explain it in plain terms using analogies, it means the explanation isn't clear enough yet. This prompt works for anything from investing to quantum physics to how a specific API works 15 - Travel plan built around how you actually travel Most travel planning starts with destinations and ends with a generic itinerary you could find on any travel blog. Claude can do something different: build a plan around your specific travel style, pace, budget, and what actually matters to you, not what's on every must-see list. The key is giving it real information about you, not just dates and locations. 16 - Monthly expense analysis with real conclusions Most people look at their bank statement and feel vaguely bad about their spending without understanding what's actually happening. Claude can turn raw numbers into a clear picture of where your money is going and what you should actually do about it. This works best when you paste real data, not estimates. 17 - Claude as your personal thinking partner Most people don't have someone in their life who will listen without judgment, ask the right questions, and help them work through something they're stuck on without pushing their own agenda. Claude can fill that role, but only if you give it the right instructions. This isn't therapy. It's structured self-reflection with an outside perspective that helps you think more clearly. 18 - Stress-test any business idea before you commit Most business ideas die because people fall in love with them before testing them. They spend months building something nobody wants because they never honestly asked whether the idea was actually good. Claude can act as a ruthless first filter. Not to kill ideas, but to find the real problems before they cost you time and money. The Actual Point Claude is not smarter than you. It does not have better ideas than you What it has is infinite patience, broad knowledge, and the ability to think through problems from angles you haven't considered. The people who get the most from Claude are not the ones with the best questions. They are the ones who have set it up to understand them, who give it real context, and who know how to use it as a partner rather than a dispenser. Most people will read this and keep opening Claude the same way they always have. Set it up once. Change how you work permanently.
