A "Copy prompt for your agent" button in the header copies SKILL.md as a prompt: one line pointing to the hosted file (for agents that can install skills) and then the skill itself, without its frontmatter, so it works in any agent, including one that can't open links. Until SKILL.md loads, or if it can't, the button copies a one-line prompt that points to it. SKILL.md teaches the format, the #d= link recipe in Python and Node, the #md= fallback for agents without code, and how to hand the link over. How it works gets a fourth card, and the README points to both. Two agents given only the copied prompt made working links, one compressed with code and one percent-encoded by hand.
