# Things 3 Task Management

This skill enables interaction with Things 3 on macOS using AppleScript. It provides scripts for creating, reading, updating, and deleting tasks, projects, areas, and tags.

## Prerequisites

- Things 3 must be installed on macOS
- AppleScript permissions must be granted to the terminal

## Core Concepts

### Built-in Lists
Things 3 has these built-in lists:
- **Inbox** - Default landing spot for new tasks
- **Today** - Tasks scheduled for today
- **Upcoming** - Tasks with future dates
- **Anytime** - Tasks available anytime (no specific date)
- **Someday** - Tasks for later consideration
- **Logbook** - Completed tasks
- **Trash** - Deleted items

### Task Properties
To-dos can have:
- `name` - Task title (required)
- `notes` - Additional details
- `due date` - When the task is due
- `when date` - When to start/show the task
- `tag names` - Comma-separated tags
- `status` - open, completed, or canceled

### Organization Hierarchy
- **Areas** - High-level life categories (Work, Personal, Health)
- **Projects** - Collections of related tasks with a goal
- **To-dos** - Individual actionable items

## Available Scripts

All scripts are in `scripts/` directory and output JSON for easy parsing.

```

### Create a project with tasks
```bash
# Create the project

# Add tasks to it
~/.claude/skills/things3/scripts/create-todo.sh "Design mockups" "" "" "" "project:Website Redesign"

## Error Handling

All scripts return JSON with:
- `success`: boolean indicating operation result
- `message`: description of what happened
- `data`: relevant data (task info, list of tasks, etc.)

Example success:
```json
{"success": true, "message": "Task created", "data": {"name": "My Task", "id": "ABC123"}}
```

Example error:
```json
{"success": false, "message": "Task not found", "data": null}
```
