Sessions you're already having — Read, Edit, Bash, the rest — quietly grow a creature in your collection. Nothing else changes about how you code.
Three constellations to choose from. Each has its own evolution chain and move set. You can change your active later.
/plugin install moonlets in Claude Code adds three things at once:
slash commands (/moonlets:status, /moonlets:roster), a
tiny hook that ships your tool calls here, and a statusline that lives at the
bottom of your terminal.
Every tool call earns XP. Hit a level boundary, the bar in your statusline fills. Hit an evolution threshold, your moonlet becomes something new. Diverse work hatches eggs of other species. Long-term play unlocks rituals for the rare ones.
Nothing to switch to, nothing to keep open. You see your moonlet at the bottom of Claude Code, always — and only when something changes does the line shift.

Three constellations to choose from. After that, the moonlet grows from your real sessions — no manual grinding.
Every event is HMAC-signed by a secret that lives only on your machine. The hook script is auditable shell.
