## Key Concepts

### Short IDs

Reminders have UUIDs like `x-apple-reminder://AB12CD34-...`. The CLI displays the first 8 characters as a short ID (`AB12CD34`). You can pass any unique prefix to commands — `rem complete AB1` works if it matches exactly one reminder.

### Natural Language Dates

The `--due` flag accepts natural language:

```bash
rem add "Call dentist" --due tomorrow
rem add "Submit report" --due "next friday at 2pm"
rem add "Quick task" --due "in 30 minutes"
rem add "Wrap up" --due eod
```

Supported patterns: `today`, `tomorrow`, `next monday`, `in 3 hours`, `eod`, `eow`, `5pm`, `2026-02-15`, and more. See [references/dates.md](references/dates.md) for the full list.

### Priority Levels

| Level | Flag value | AppleScript value |
|-------|-----------|-------------------|
| High | `--priority high` | 1 (range 1-4) |
| Medium | `--priority medium` | 5 |
| Low | `--priority low` | 9 (range 6-9) |
| None | `--priority none` | 0 |

### Output Formats

All read commands support `-o` / `--output`:

- **table** (default) — formatted table with borders
- **json** — machine-readable JSON
- **plain** — simple text, one item per line

The `NO_COLOR` environment variable is respected.

### URL Storage

macOS Reminders has no native URL field. rem stores URLs in the notes/body field with a `URL: ` prefix and extracts them for display.

## Common Workflows

### Daily review
```bash
rem overdue                          # Check what's past due
rem upcoming --days 1                # See today's reminders
rem list --list Work --incomplete    # Focus on work items
```

### Batch operations with JSON
```bash
rem export --list Work --format json > backup.json
rem import backup.json --list "Work Archive"
```

### Scripting with JSON output
```bash
# Get overdue count
rem overdue -o json | jq 'length'

# List all incomplete reminder titles
rem list --incomplete -o json | jq -r '.[].name'
```

## Public Go API

For programmatic access, use [`go-eventkit`](https://github.com/BRO3886/go-eventkit) directly:

```go
import "github.com/BRO3886/go-eventkit/reminders"

client, _ := reminders.New()
r, _ := client.CreateReminder(reminders.CreateReminderInput{
    Title:    "Buy milk",
    ListName: "Shopping",
    Priority: reminders.PriorityHigh,
})
items, _ := client.Reminders(reminders.WithCompleted(false))
```

See [go-eventkit docs](https://github.com/BRO3886/go-eventkit) for the full API surface.

## Limitations

- **macOS only** — requires EventKit framework and `osascript`
- **No tags, subtasks, or recurrence** — not exposed by EventKit/AppleScript
- **`--flagged` filter is slower** (~3-4s) — falls back to JXA since EventKit doesn't expose flagged
- **List deletion** may fail on some macOS versions
