Almost nobody knows Claude has secret codes. Here are 14 you can (actually) download and own: "Secret codes" sounds like a trick you type. It's not. It's a Skill - a long, detailed prompt I already wrote, turned into one slash command. Everything you'd normally type into a long prompt - your voice, rules, structure - lives inside the Skill. So you type one word instead of one page: "/my-viral-linkedin-post AI tools I actually use." That's the secret. The work is already in there. ✦ Part 1 - Download all 14 Claude Skills (in 2 mins): Step 1. Go to http://how-to-ai.guide. Step 2. Subscribe for free. Don't pay anything. Step 3. Open the welcome email (don't skip this). Step 4. Click the Notion link inside it. Step 5. Open the "Claude Skills" folder. Step 6. Download all 14 Claude Skills. Step 7. Each one is a small file ending in .md. ✦ Part 2 - Upload the Skills to Claude (3 minutes): Step 1. Open Claude → Customize in the left menu. Step 2. Click on Skills. Step 3. Click Add → Upload a skill. Step 4. Select the first file you downloaded. Step 5. Repeat for all 14 (you do this once). Step 6. Start any chat & type the slash command, like /my-viral-linkedin-post. That's the whole setup. You'll never do it again. Now type the slash command. Done. A few of the 14 you'll reach for daily: /linkedin-hook: writes the viral format LinkedIn hook /meeting-notes: turns transcripts into action items. /excel-style: makes your data look like a pro built it. /anti-writing: turns AI text into a human-written one. Want to build your own from scratch? Here's how: 1. Open Claude Cowork. Pick Opus 4.8 (High). 2. Type /skill-creator & name the task. 3. Answer the questions it asks you. Be specific. 4. It writes the SKILL .md for you. Review it. 5. Add: "Do NOT use for [what it should ignore]." 6. Save the folder. 7. Upload it the same way as Part 2 above. One /command & Claude reads it as you wrote it. That's the real secret shortcut. You build it once. It works forever. Get all 14 Skills, free: http://how-to-ai.guide.
