Meeting Scheduler

Encapsulates the ~10 manual steps of "set up a quick meeting" into one command: resolve attendee emails → check the owner's calendar for the slot → dedup-check → create the event + send invites → report the link.

Usage: /meeting-scheduler [what to schedule]

ARGUMENTS: $ARGUMENTS

Scope (read first)

This skill handles the mechanical core only. It does NOT negotiate availability across people — proposing times, collecting "does 3pm work?", juggling everyone's free/busy stays an interactive conversation you have with the owner (and, if asked, the attendees). Once a concrete slot is chosen, this skill does the rote work.

Authority note. Creating and sending a calendar invite is an owner action. Run the create+send step only when the owner has invoked this skill for a concrete meeting. Never auto-send speculatively — default to a dry-run and show the plan first. The helper enforces this: it defaults to --dry-run and only creates with an explicit --send.

Inputs

Input	Required	Notes
title	yes	Event summary, e.g. "Sutando sync"
attendees	yes	Either explicit emails (--attendees) or names to resolve (--resolve)
when	yes	Start time — ISO 8601 (2026-07-25T15:00) or today/tomorrow HH[:MM][am/pm]
duration	no	Minutes; default 30
location	no	Room, address, or a video link
description	no	Agenda / notes

Emails must come from a Gmail lookup — the identity map (workspace/.claude-sutando/projects/<slug>/memory/reference_identity_map.md) resolves a name to a person (and their Discord/GitHub ids) but does not store email addresses. Use the map to disambiguate who is meant; get the address from Gmail.

Run order

Everything below is done by scripts/schedule_meeting.py, which shells out to the gws (Google Workspace) CLI. You can run it directly, or perform the steps by hand with the gws commands shown.

1. Resolve attendee emails (names → emails via Gmail)

For each name, search recent mail and read From/To headers to extract the address:

gws gmail users messages list --params '{"userId":"me","q":"\"Alice\" newer_than:365d","maxResults":10}'
# then, per hit id:
gws gmail users messages get --params '{"userId":"me","id":"<id>","format":"metadata","metadataHeaders":["From","To","Cc"]}'

Strip any line containing keyring from gws output before parsing JSON. For the ag2.ai account, set GOOGLE_WORKSPACE_CLI_CONFIG_DIR=$HOME/.config/gws-ag2 (the helper's --account ag2 does this). If a name is ambiguous, confirm with the owner rather than guessing.

2. Check the OWNER's calendar for the slot

Read the owner's events across that day and flag anything whose busy time overlaps [start, end) (back-to-back is not a conflict; transparency:transparent / all-day events don't block):

gws calendar events list --params '{"calendarId":"primary","timeMin":"2026-07-25T00:00:00-07:00","timeMax":"2026-07-26T00:00:00-07:00","singleEvents":true,"orderBy":"startTime"}'

3. Dedup-check

From the same day's events, refuse if one already has the same title (case/space-insensitive, ignoring cancelled ones) — prevents a double-booked duplicate invite.

4. Create the event + send invites

Only on explicit owner action (--send). sendUpdates=all makes Google email the invitations:

gws calendar events insert \
  --params '{"calendarId":"primary","sendUpdates":"all"}' \
  --json '{"summary":"Sutando sync","location":"Meet link","description":"...","start":{"dateTime":"2026-07-25T15:00:00","timeZone":"America/Los_Angeles"},"end":{"dateTime":"2026-07-25T15:30:00","timeZone":"America/Los_Angeles"},"attendees":[{"email":"[e-mail]"},{"email":"[e-mail]"}]}'

5. Report the event link

Print the htmlLink from the insert response back to the owner.

The helper script

# Dry-run (default) — resolve, check, dedup, report. NO changes:
python3 skills/meeting-scheduler/scripts/schedule_meeting.py \
  --title "Sutando sync" --when 2026-07-25T15:00 --duration-min 30 \
  --resolve "Alice, Bob"

# Create + email invites (owner action):
python3 skills/meeting-scheduler/scripts/schedule_meeting.py \
  --title "Sutando sync" --when 2026-07-25T15:00 --duration-min 30 \
  --attendees "[e-mail],[e-mail]" --location "https://meet.google.com/xxx" --send

# Override a detected conflict/duplicate (owner's explicit call):
#   ... --send --force

Flags: --title --when --duration-min --attendees --resolve --location --description --calendar (default primary) --timezone --account {default,ag2} --gmail-lookback --send/--dry-run --force --self-check --verbose.

Fail-safe behavior:

• Defaults to --dry-run — nothing is created or emailed without --send.
• On a conflict or a same-title duplicate, it refuses to create even with --send, unless --force is also given (the owner's explicit override).
• If no attendee email is present (none given, none resolved), it stops.

Offline self-check

The pure logic (when-parsing, conflict overlap, dedup, email-pick) is unit-tested without the network:

python3 skills/meeting-scheduler/scripts/schedule_meeting.py --self-check
python3 tests/meeting-scheduler.test.py

Notes / limitations

• Natural-language dates are intentionally minimal — ISO 8601 and today/tomorrow HH[:MM][am/pm] only. For "next Tuesday afternoon" etc., resolve it to a concrete ISO time (the owner picks the slot) before calling the helper.
• Free/busy is checked on the owner's calendar only — attendee availability is the interactive part this skill deliberately leaves out.
• Timezone defaults to the host's IANA zone (falls back to America/Los_Angeles); override with --timezone.
