About this skill

Things 3 (macOS)

Manage Things 3 tasks using URL schemes (built-in) and things-cli (optional). Requires Things 3 app installed from the Mac App Store.

Prerequisites

Things 3 must be installed: https://culturedcode.com/things/

Option 1: URL scheme (no install, built-in)

open "things:///add?title=<Task Name>"

Option 2: things-cli for richer scripting:

npm install -g things-cli

Verify:

things --version

Commands

URL Scheme (works without any CLI install)

# Add a task to Inbox
open "things:///add?title=Buy+groceries"

# Add with notes and due date
open "things:///add?title=Submit+report&notes=Include+Q1+data&deadline=2026-03-25"

# Add to a specific list/project
open "things:///add?title=Write+tests&list=Work"

# Add with tags
open "things:///add?title=Review+PR&tags=code,review"

# Add to Today
open "things:///add?title=Call+Alice&when=today"

# Show the Today list
open "things:///show?id=today"

# Show Inbox
open "things:///show?id=inbox"

# Show Upcoming
open "things:///show?id=upcoming"

things-cli (if installed)

Command Description
things inbox List inbox tasks
things today List today's tasks
things upcoming List upcoming tasks
things search "<query>" Search tasks
things add "<title>" Add a task to inbox
things logbook View completed tasks

Usage Examples

Add a task with deadline:

open "things:///add?title=File+taxes&deadline=2026-04-15&notes=Use+last+year+as+reference"

Show today's tasks (opens Things app):

open "things:///show?id=today"

Add task to a project:

open "things:///add?title=Write+unit+tests&list=My+Project&tags=dev"

List today's tasks via CLI (if installed):

things today

Search for a task:

things search "quarterly report"

Rules

  • Always check that Things 3 is installed: ls /Applications/Things3.app 2>/dev/null || ls "$HOME/Applications/Things3.app" 2>/dev/null
  • If not installed, direct user to https://culturedcode.com/things/ and stop
  • URL scheme works without things-cli — always try URL scheme first
  • URL-encode all parameter values: spaces → +, special chars → %XX
  • The open command launches the Things app and adds/shows the item
  • When using URL scheme, Things 3 must be running or it will open automatically
  • Default destination for new tasks is Inbox unless user specifies a list or when=today
  • For reading/listing tasks, prefer things-cli if installed; if not, use open to show the relevant list in the app
  • Keep responses concise: confirm "Added to Things: " in one line
