Put this in your README

markdown for agents

Hand a coding agent one prompt and it adds the star-history chart, a stars-and-forks badge, and whichever repo-health charts fit tofacebook/folly's README — light and dark variants, alt text, and the measured numbers already filled in.

Paste it into Claude Code, Cursor, Codex, or any coding agent with your checkout open. It carries the measured numbers, the exact snippets, and the rules — including replacing an existing star-history widget in place rather than stacking a second chart under it.
