ClaudeスキルとプロンプトTaxの違い

Every time you open a new Claude session and type the same context again, you are paying a tax. > "You are a senior copywriter with 10 years of experience" > "Always respond in bullet points" > "My brand tone is direct and conversational" You type it -> Claude uses it -> You close the tab -> Next session -> gone. Then you type it again. This is the prompt loop, most people are stuck in it forever. There is a way out, it is called skills, and the difference between someone who uses prompts and someone who uses skills is not just workflow preference. It is the difference between a tool that resets every day and a tool that compounds every day. Picture from: rubenhassid There are actually three levels, most people are on level one... Prompts, Projects, Skills. Same AI, tho three completely different setups, here is how to think about them. > LEVEL 1 / Prompts are telling a stranger your job every single morning, it works, but tomorrow they forgot everything and you explain it again. > LEVEL 2 / Projects are giving a new hire a binder on day one, you upload your files, your instructions, your voice, every chat inside that project knows you, your context sticks. > LEVEL 3 / Skills are training an employee once, forever, you teach Claude a process, it fires automatically every time it recognizes the task, no prompt needed, no opening the right project, claude just knows. Why you're stand out if you use skills Most people never make it past Level 1, this article is about getting to Level 3. How to Actually Move Through the Levels: Level 1: Start with a Prompt Open Claude -> type your task -> get an answer -> it works. But tomorrow Claude forgot everything, and you just have to re-explain, again every single chat, that is the tax. Level 2: Move to a Project Go to claude.ai, create a Project, and upload your voice file and instructions. Now every chat inside that Project knows your context, your style, and your tone. It sticks. Still not perfect though, you still have to open the right Project. You still have to remember it exists. Level 3: Build a Skill Open Claude Code or Cowork, select Opus 4.6 with extended thinking. Then type: Use the skill-creator to help me build a skill for [your most repeated task] Claude interviews you, answer with specifics. "I write reports" is useless, that is not a skill. "I write weekly reports that start with the headline metric, three sections max, next steps as bullets" is a skill. The specificity is the skill. Then save it, go to Settings, Capabilities, Skills, and upload, open a new chat, type your task normally, the skill fires on its own, no slash command. Claude just knows. The 3-conversation rule If you have typed the same instructions more than three times, that is a skill begging to be built, stop retyping it, build it once. What a prompt actually is A prompt is an instruction you give Claude in the moment. It works, it gets answered, then it disappears. Every prompt exists inside a single session, when that session closes, the context is gone. Claude does not remember your tone. It does not remember your brand. It does not remember that you like concise answers or that you always want three options instead of one. Next time you open Claude, you are starting from zero, again. Prompts are one-time transactions. Useful but temporary. You get what you put in and nothing carries forward. What a Skill Actually Is / First skill: Hook Generator 🚨 (PSST...THE MOST IMPORTANT SKILL AT THE END) A skill is a structured .md file that tells Claude how to behave, not just what to do. You write it once. You install it once. From that session forward, Claude has absorbed it as part of how it operates. No re-explaining. No re-prompting. No tax. Here is what a skill looks like. This is the Hook Generator, copy it right now: --- name: hook-generator description: Produces attention-grabbing hooks for videos, social posts, and content intros to maximize engagement. --- # Hook Generator ## Overview Creates compelling openings to capture attention immediately. ## Features - Short, impactful - Curiosity-driven - Adaptable to content type ## Output Format - Hook sentence - Optional follow-up intro ## Instructions - Focus on curiosity or bold statements - Keep concise - Match audience interest ## Constraints - Avoid generic hooks - Maintain relevance That is a skill, persistent instructions that shape Claude's behavior every time it activates, without you saying a single word about hooks or engagement or conciseness. The difference is not complexity. It is permanence. Why prompts do not compound Here is the honest picture of what the prompt loop looks like over 30 days. > Day 1: you write a great prompt, claude gives you a great answer. > Day 2: new session, you write the same prompt again. > Day 15: you have written roughly the same context 15 times. > Day 30: you are exactly as productive as day 1, Nothing has accumulated. The output quality depends entirely on what you remember to include each time. On a tired day you forget something. The output suffers. On a busy day you skip the context entirely. Claude gives you the generic version. Prompts make you the bottleneck. Every single session. Why skills do compound Skills work the opposite way. Day 1: you install a skill. Takes 10 minutes. Day 2: Claude already knows. You just start working. Day 15: you have added three more skills. Each one building on the last. Day 30: your Claude behaves completely differently from everyone else's Claude. It writes in your tone without being told. It structures outputs the way you like without asking. It applies frameworks automatically. Setup cost was one hour spread across the first week. The return is every session after that running at a higher baseline. That is compounding. The work you did in week one pays dividends in month six. The personal skills stack: Here is the full stack across five categories guys.

Super important: How to Install a Skill Three ways depending on how you work. > Claude Code Save the skill as a .md file and drop it into your .claude/skills/ folder inside your project. Claude Code picks it up automatically next session, this is the only method that truly compounds because it persists across every session automatically. > Claude(.)ai Projects Paste the skill content into a Project, every conversation inside that Project starts with the skill already loaded. No re-prompting. Best option if you are not using Claude Code yet. > Single session Paste the skill at the top of your conversation before anything else. Activates for that session only. Not persistent but still better than nothing. The skills in this article took about two hours to build,the compound return on those two hours has no ceiling. That is the difference between prompts and skills, 1 is a transaction, 1 is an investment. Start with one skill, for instance the Hook Generator if you make content. The Code Review skill if you build things etc, install one, use it for a week, and you will understand why you never go back to prompts alone. - Leo
