Most of you are running Claude. Some on Desktop. Some on Code. A few running full agent systems. All of you have tried to teach the same lesson twice and watched Claude forget it the next morning. I built a small file that fixes that. It is called a self-learning skill. Today I am sharing it for free. Drop it into your Claude Code project and your agent starts remembering every correction you give it. Works with Claude Code, Claude Code coworkers, and Claude Desktop (with Filesystem MCP). One file. No code to write. ## What It Does A self-learning skill turns one correction into one permanent rule. You correct your agent once. The file captures the fix. Every future session, that rule loads before the agent works. The same mistake never happens twice. Three lines per lesson. That is the whole format: ``` ## Learned 2026-04-15 TRIGGER: What happened. One line. LEARNING: The specific insight. ACTION: What to do different next time. ``` The agent loads these entries on session start. When the current situation matches a past trigger, the rule fires. When something new breaks, the agent writes a fresh entry at the bottom. Next session, that rule is live too. ## Why It Compounds James Clear said 1% better every day is 37 times better after a year. The math here is the same. Week 1 you correct 10 mistakes. 10 new rules live forever. Week 4 those mistakes stop. Different ones show up. 8 more rules. Week 12 the agent handles the work. You correct rare edge cases. 3 rules. Month 6 the agent catches things you forgot to teach it. Every correction is a one-time tax. Every rule is permanent interest. ## Three Real Examples From My System ### 1. Image Agent Learned What a Metaphor Is (This Morning, 44 Minutes) At 09:54 CET today, my Image Agent shipped a 4-zone color-coded reference card for the Apr 15 LinkedIn post. Dense. Clean. Technically strong. I looked at it and said: "No, a metaphor." Four words. My Chief of Staff pitched five metaphor options. I picked one: a craftsman's workshop journal. A leather notebook open on a wooden workbench. Each page is one SKILL.md file. The self-learning page is the hero, with margin notes added after every correction. Tabs for each description field.

You saw the LinkedIn post. Here is the kit. This is the exact folder my Image Agent uses to generate one infographic every day. Open it in Claude Code. It reads 764 lines of creative system before touching a single pixel. Visual metaphors, density rules, 12 design moves, anti-template checks, quality gate. The same brain my agent uses. How it works: You send your post caption. That is it. The agent handles everything. Picks the visual metaphor. Writes the Gemini prompt. Generates the image. Runs quality checks. Delivers the PNG. You do not pick layouts. You do not write prompts. You do not give design instructions. The agent figures it out. What is in the kit: - CLAUDE.md -- the agent brain. Full execution checklist it follows for every image. - scroll-stopping-visuals.skill -- 764 lines. Visual metaphors, 12 design moves, density standards, quality gate. The agent reads this before every image. No exceptions. - 5 example briefs -- one per visual metaphor (hourglass, cheat sheet, comparison, pyramid, metro map). So the agent knows how to think about different topics. - feedback-log.md -- this is how the agent learns your taste. Say "headline too small" and it adjusts next time. - README.md -- setup in 3 steps. Setup: 1. Get a Gemini API key (free at aistudio.google.com/apikey) 2. Paste it in the .env file 3. Open the folder in Claude Code First message to send: Set up my brand The agent asks 5 questions. Your name, handle, brand colors, vibe. Takes 2 minutes. Saves your brand config. Updates the skill file to match YOUR style. After that, just paste your caption: "Here is my LinkedIn post: [paste]. Make me an infographic for this." Or keep it simple: "make me an infographic about 5 ways to save time with AI" Cost is about $0.04 per image. A dollar a month for daily posting. The file is below. Download it. Ship tonight. Drop a comment when you generate your first one. I want to see what you make.
