How to use it

  1. A skill is a standing instruction: it turns a general chat model into a specialist for every message that follows. Read it once so you know what it will do.
  2. Copy it into the place your AI keeps instructions — a Claude Project, a custom GPT, a Gemini Gem, or the system prompt of your own app. On a plan, the .md file drops straight into a Claude Code skills folder.
  3. Replace anything in [BRACKETS] with your details. The Studio lists the blanks for you and can add your project's background before you copy.

Works with

Any chat AI — ChatGPT, Claude, Gemini, Copilot, Grok, Mistral or a local model. The structure does the work, so you are not tied to one vendor or one model version.
