# Migration: reminder_check.py → calendar todo

## What's changing

| Before | After |
|--------|-------|
| `scripts/reminder_check.py` | `skills/calendar/scripts/calendar.sh todo` |
| `reminders/active.md` (markdown table) | `calendars/tasks/*.ics` (RFC 5545 VTODO) |
| Local only, no sync | CalDAV sync to all devices via vdirsyncer |
| No native reminders | VALARM triggers on phone/desktop |
| Cron reads markdown | Cron reads .ics via todoman |
| Custom Python parsing | todoman for robust RFC 5545 VTODO handling |

## Prerequisites

- [ ] Install todoman (see below)
- [ ] Configure todoman (see below)
- [ ] `calendar.sh todo add --dry-run` works
- [ ] `~/.openclaw/workspace/calendars/tasks/` directory exists (auto-created by `todo add`)
- [ ] vdirsyncer has a `cal/tasks` pair configured
- [ ] Live tests 8-12 from `TESTING.md` pass on the Linux machine

## Step 0: Install and configure todoman

### Install

```bash
# Debian/Ubuntu (the agent's Linux machine)
pip install todoman

# macOS (Homebrew)
brew install todoman
```

The CLI command is `todo`.

### Configure

Create `~/.config/todoman/config.py`:

```python
path = "~/.openclaw/workspace/calendars/tasks/"
date_format = "%Y-%m-%d"
time_format = "%H:%M"
default_due = 24
default_priority = 0
humanize = True
```

### Verify

```bash
# Should list todos (or show empty list without errors)
todo list
```

## Step 1: Migrate pending reminders

Two items are pending in `reminders/active.md`:

```bash
SKILL_DIR=~/.openclaw/workspace/skills/calendar

$SKILL_DIR/scripts/calendar.sh todo add \
  --summary "跟进iui保险报销" \
  --due "2026-03-25" \
  --priority medium \
  --description "确认iui（人工授精）费用保险报销进度，避免过期"

$SKILL_DIR/scripts/calendar.sh todo add \
  --summary "打电话给progyny问iui报销" \
  --due "2026-04-04" \
  --priority medium \
  --description "询问iui报销相关事宜"
```

Note: `todo add` emails each item to `mail@luyx.org`. This is expected.

Verify:
```bash
$SKILL_DIR/scripts/calendar.sh todo list
```

## Step 2: Set up cron

Ask the agent to set up a daily cron job via `openclaw cron`:

> Set up a daily cron at 8:00 AM PST that runs:
> `~/.openclaw/workspace/skills/calendar/scripts/calendar.sh todo check`
> and emails the output to mail@luyx.org with subject "📋 今日待办清单"

The old `reminder_check.py` cron should be removed by the agent at the same time.

## Step 3: Verify

- [ ] `todo list` (todoman directly) shows both migrated items
- [ ] `calendar.sh todo list` shows both items with Chinese priority labels
- [ ] `vdirsyncer sync` completes without errors
- [ ] Todos appear on phone/CalDAV client
- [ ] Next morning's cron email arrives with the new format

## Step 4: Clean up

After a few days of successful operation:

```bash
# Remove old reminder system
rm scripts/reminder_check.py
rm -r reminders/
```

## Rollback

If something goes wrong, the old system is still intact until Step 4:
- `reminders/active.md` is unchanged
- `scripts/reminder_check.py` still works
- Re-add the old cron entry to restore the previous behavior
