    "description": "newdle, from the Indico team at CERN, lets an organiser propose candidate slots, see when participants are free from Exchange free/busy, and collect answers on a poll. It is a Flask backend with a React frontend, configured in newdle.cfg (SSO over OIDC, database, SMTP, free/busy providers) and shipped with Docker Compose. The JSON API behind the UI is not documented for agents.",
