## Tools (as reported by the server, not verified)

- `create\_event`: Create a sync.day availability poll and get its share link. Candidate days run from startDate to endDate \(inclusive; or give days instead\). Each day offers candidate START times from hourFrom, every startStepMinutes, as long as start + durationMinutes \<= hourTo. Returns slug, public url \(share this\)
- `parse\_event\_text`: Turn a natural-language sentence \(Chinese works best\) into create\_event input using sync.day's AI parser. Does NOT create anything; review the result, then call create\_event. Example: '下周六或周日下午聚餐，大概 3 小时'.
- `get\_event`: Read an event: settings, every candidate start key per day \(startOptions\), who has answered \(participants with their start keys; names may repeat\), the top 10 start times by head-count \(ranked\), the starts EVERYONE with picks can make with their votes \(voteOptions\), each person's vote \(votes\) and de
- `submit\_availability`: Save \(or replace\) one person's availability: the candidate start keys they can make, from get\_event.startOptions. The person is identified by \`identity\`, not by name: the same identity later overwrites the same row \(and can rename it\), a different identity with the same name is a second participant.
- `remove\_participant`: Organiser only: remove one participant by name \(the oldest row with that name when it repeats\), together with their vote. Requires the adminKey from create\_event.
- `update\_event`: Organiser only: change any event settings \(same fields and rules as create\_event; omitted fields keep their current value; endDate wins over days\). Existing picks are kept; those no longer valid starts are just hidden.
- `vote\_time`: Approval voting: set every start one person accepts \(replaces their earlier approvals; an empty list clears them\). The voter is the \`identity\` used in submit\_availability and must have at least one start saved. Only keys listed in get\_event.voteOptions are accepted; the error lists the current optio
- `decide\_time`: Organiser only: settle on a start time \(locks availability picking and voting; the page shows 已定\). Pass start=null to reopen. Requires the adminKey from create\_event.
