We built Sundial because agent skills shouldn't live in silos.
Every coding agent — Claude Code, Cursor, Copilot, Codex, and dozens more — can read markdown. That shared surface means a single skill file can work everywhere. Sundial is the open registry that makes discovering, sharing, and installing those skills effortless.
We're working on team workspaces, skill analytics, and deeper IDE integrations. If you have ideas, come say hi — we'd love to hear from you.
