# gcalcli calendar wrapper + reminder planner This skill provides: - `scripts/calendar` — wrapper around `gcalcli` - `scripts/calendar_reminder_plan.py` — produces a JSON plan for reminder scheduling - `references/openclaw-calendar.example.json` — example config format ## Config Copy the example config to a private location and edit it: - Default path: `~/.config/openclaw/calendar.json` - Override with env: `OPENCLAW_CALENDAR_CONFIG=/path/to/calendar.json` ## Requirements - Required: `python3`, `gcalcli` - Optional (for CalDAV/iCloud): `vdirsyncer`, `khal` ## Security notes (why ClawHub may flag this) This skill *invokes external binaries* and is config-driven. - The planner runs `gcalcli`/`khal` using `subprocess.check_output([...], shell=False)` (argument-list form; safe against shell injection from event titles). - If you wire a cron job to run `vdirsyncerSyncCommand`, make sure you run it as an **argv list** (`subprocess.run(cmd_list, shell=False)`), not as a shell string. - Only point `gcalcliPath` / `khalBin` to **trusted binaries** (prefer absolute paths). Don’t run untrusted paths. ## Auth (Google) `gcalcli` requires OAuth. On headless servers you may need SSH port-forwarding. The wrapper uses `--noauth_local_server` to print instructions. ## Reminder planning The planner outputs a JSON blob describing reminders to schedule. A separate cron job (or an agent turn) can read it and create one-shot OpenClaw reminders. Defaults: - Ignore birthdays. - Timed events are considered important. - All-day events only trigger reminders if their title matches configured keywords. ## Wiring a daily reminder scheduler (OpenClaw) Create a daily cron job (e.g. 00:05 local time) that: 1) If CalDAV is enabled in config, runs the configured `vdirsyncer` sync command. 2) Runs `scripts/calendar_reminder_plan.py` to get a JSON plan. 3) For each planned reminder, creates a one-shot OpenClaw `systemEvent` reminder at `reminderAtUtc`. 4) Writes a small state file so you don’t schedule duplicates. (Our skill intentionally provides the wrapper + planner; scheduling is left to your cron/agent wiring.)
