Star rating

Five stars, an optional comment and bars that grow with the vote.

Five stars a visitor can choose with the mouse or the arrow keys, an optional comment and a histogram whose bars grow when the vote counts. The votes are anonymous. The bars start from sample counts you pass, marked as sample content.

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 "Star rating" (rating-stars): Five stars, an optional comment and bars that grow with the vote. 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.
