The meta-skill that builds new AI skills from scratch and audits the ones you already own. Most people building a library of AI skills hit the same two walls. First, they write skills that read fine but never fire, because the description does not match how they talk in the moment they need it. Second, the stack quietly rots: a skill written in March still claims a platform limitation that disappeared in May, two skills overlap so the assistant picks unpredictably between them, and nobody notices until an output comes back wrong. This skill covers both jobs. In builder mode, it interviews you about a raw skill idea and writes a properly structured SKILL.md file with a trigger-optimized description, the right setup tier, and a draft-test-tighten loop before you install anything. In evaluator mode, it scores your existing skill files against a weighted 100-point rubric covering trigger accuracy, rule compliance, output completeness, bloat and staleness, and overlap, then returns a health report with fix briefs, consolidate recommendations, and a list of gaps worth building next. You walk away with installable skill files that fire when they should, and a monthly audit flow that keeps every skill in your stack earning its place. It even tests your should-trigger prompts against the draft in the same conversation, so weak spots get fixed in the file instead of patched in chat. This is a Plug & Play Skill. Install it once and it works immediately. No setup interview, no questions before you start. Say the trigger phrase and your AI picks it up from there. Plug & Play Skills are calibrated for general use out of the box, with no customization required to get value from day one. What is a Portable Brain Skill? A Portable Brain Skill is a plain text file, specifically a Markdown (.md) file, that you install directly into your AI account. Claude and ChatGPT both support Skills natively, built on the same open standard, so the exact same file installs in either one. Once it's in, your AI reads it automatically at the start of every relevant conversation, so you never have to re-explain your brand, your process, or your preferences again. It works like permanent memory that loads on demand. Because you own the file itself, you are not locked into any platform. Install it in Claude today, in ChatGPT tomorrow, or in both at once. Your investment travels with your business, not with any single tool. Use It on Any AI Platform This Skill installs directly in Claude and in ChatGPT with no conversion required. ChatGPT's native Skills support works on any paid ChatGPT plan (not available on the free plan yet), and Claude Skills work on both free and paid Claude plans. Every Portable Brain Skill also includes free access to the Portable Brain Skill Extractor, a tool that converts your .md Skill file into formats for every other platform: Google Gem (Gemini) Plain System Prompt Project Knowledge file NotebookLM format Access details are included with your purchase.
