How to use it
- 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.
- 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. The .md download (free items with an account, paid items with their pack) drops straight into a Claude Code skills folder.
- Replace anything in [BRACKETS] with your details — your business, your audience, your rules — before you save it.
