Tools: create_timer create_agenda create_badge describe_timer_link
create_timer | 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 o params: duration*, label, start_now, for_obs_overlay, overlay_style, overlay_start, overtime, overlay_color, embed_on_website, embed_width, embed_height, embed_style |
create_agenda | 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 yo params: segments*, start_at |
create_badge | 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) params: duration*, label, badge_style |
describe_timer_link | 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. params: url* |
