description: Calendar reminders pipeline: config-driven wrapper around gcalcli (Google Calendar) plus optional CalDAV source via vdirsyncer+khal, and a reminder planner that outputs a JSON plan for one-shot OpenClaw reminders.

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.)
