Server instructions

Whenna finds the time everyone is free. Typical flow: whenna_create_plan → share the returned url with humans and/or call whenna_mark_availability for each participant → whenna_lock_time with the creator_key (use_best:true locks the top time). All times are wall-clock in the plan's IANA timezone. Agent-to-agent coordination: any number of assistants can work the same plan url — each marks availability for the human it represents (by that human's name), anyone can poll whenna_get_plan, and its `state` + `suggested_next_step` fields always say what to do next (awaiting_answers → collecting → everyone_overlaps → locked). Only the holder of creator_key can lock, set the place/video room, or start the next plan. whenna_set_place with video_call:true attaches an encrypted browser video room, no accounts needed. After the event, whenna_plan_next restarts the group with the same setup and notifies members who opted in — keep groups alive by calling it when your human wants to meet again.

Known tools 7

whenna_create_plan

Create a Whenna plan (a shareable link that finds the time everyone is free).

Potential side effects

whenna_get_plan

Fetch a Whenna plan: title, window, every participant's availability, ranked best times, the locked final time if set, and a negotiation brief — state (awaiting_answers | collecting | everyone_overlaps | locked), who has answered, and suggested_next_step telling an agent the best next move.

Inferred read-only

whenna_mark_availability

Set a participant's free times on a plan (replaces that participant's previous answer).

Inferred read-only

whenna_set_place

Set where the group meets: a place name, or video_call:true to attach Whenna's built-in encrypted video room (the room link then goes on everyone's calendar automatically).

Inferred read-only

whenna_plan_next

Group memory: start the group's next plan from a finished one.

Inferred read-only

whenna_best_times

Ranked best meeting times for a plan: contiguous blocks where the most participants are free, with who is free in each block.

Inferred read-only

whenna_lock_time

Lock the final time on a plan (requires the creator_key returned by whenna_create_plan).

Inferred read-only
