How to use a game dev skill
Three steps in Claude Code, Codex, Cursor or any agent that reads SKILL.md.
- 01
Install it
Run the command on the skill's page, or copy the install prompt and let your agent run it.
- 02
Ask in plain words

Review and play
Run the game, read what the agent changed, and ask for fixes in the same session.
