Day and night switch

A switch whose knob turns from sun to moon, with a scene that follows.

The knob morphs from a sun to a moon while a small scene turns from day to a starry night. The mode lives in the component only: nothing is stored and the host page is left alone.

Build one with your agent

Paste this into your agent. It asks you before it signs in, pays or goes further than checking and publishing.

Build me a Taggor component like "Day and night switch" (toggle-day-night): A switch whose knob turns from sun to moon, with a scene that follows. Fetch https://taggor.dev/agent-setup/prompt.md and follow its instructions to set me up for Taggor. Ask me before you sign in, create an account, accept terms, pay for anything or type a secret. Check it with `taggor check` and publish it with `taggor publish`, and stop there. Do not promote it to production, attach it to a site, roll back anything or use --yes, --force or --force-drop-invalid unless I ask for exactly that in this conversation.
