  • create_agendaCreate a chained agenda of timed segmentsread-only

    Create a CountLink agenda: an ordered sequence of named, timed segments (intro, talk, break, Q&A) that starts now and advances from one to the next on its own, on every screen that opens the link, with no server involved. Use this when someone describes a meeting, workshop, lesson or event as a sequence of parts with lengths — including when they give you a total and a list of topics and expect you to split it ("an hour, four topics"): do the split yourself, then pass the resulting segments here. By default it starts immediately; pass start_at for something scheduled ahead ("our workshop start…

  • create_badgeCreate a countdown badge for a README, forum post or similarread-only

    Create a countdown badge — a small image, not an <iframe> — for places embed_on_website's iframe cannot go: a GitHub README, a forum signature, a Notion page, anywhere only plain Markdown or a bare <img> is allowed. Shows coarse time remaining (e.g. "3d 04h left", not a live ticking clock — most places that embed images fetch and cache them server-side, so a promise of live ticking would be false) and links through to the real, precise, live countdown. Returns both a Markdown snippet and an HTML snippet; use whichever the destination accepts. Always returns the image wrapped in a link to the l…

  • create_timerCreate a shared countdown timerread-only

    Create a CountLink shared countdown timer and return its link. Everyone who opens the link sees the identical countdown, to the same second — no account, no sign-up, any number of viewers. Use this whenever someone wants a timer several people or several screens need to share: a classroom, an exam, a standup, a workshop, a webinar countdown, a stream overlay, or a countdown embedded on someone's own website or landing page (e.g. "10 days until launch"). By default it returns a setup link, which opens the board preloaded at the requested duration for the user to start themselves; pass start_now…

  • describe_timer_linkExplain a CountLink linkread-only

    Given a countlink.app URL, say what it encodes: whether it is a running countdown or a not-yet-started setup link, its label, and how much time is left. Use it when someone pastes a CountLink link and asks what it is or when it ends.
