How to install
Which AI tool do you use?
1. Open the Terminal app on your computer, paste the line below and press Enter
npx skills add anthropics/skills @slack-gif-creator -g With no tool name, the command looks for the AI tools on your computer and asks where to install. If it says npx is missing or too old, install the latest Node.js (22 or newer) first.
First time using the terminal?
- How to open it: on a Mac, press ⌘ + Space and search “Terminal”. On Windows, search “PowerShell” in the Start menu. In Cursor, Trae or VS Code, use the menu Terminal → New Terminal.
- Windows says “running scripts is disabled”: change npx at the start of the command to npx.cmd and try again.
- If a list pops up: move with the arrow keys, press Space to tick the tools you want, then press Enter.
- How to tell it worked: you'll see a success message. Reopen your AI tool and ask “What Skills do you have now?” to check.
Don't feel like opening a terminal?
Tools like Claude Code, Codex, Cursor and Trae can run commands themselves. Send them this:
Please run this command in my terminal and tell me how it went:npx skills add anthropics/skills @slack-gif-creator -g 2. Reopen your AI tool
New Skills only get picked up after a restart.
3. Just say what you want
Say it the way the examples do. To call it by name, say “Use slack-gif-creator to help me…”.
