Good for

  • Review today's tasks and inbox
  • Add tasks with deadlines and checklists
  • Find and update existing tasks
  • Organize tasks by project and tag

Overview

What it does

things-mac lets your agent review, add, and update tasks in Things 3 on macOS. It lists your inbox, today’s tasks, and upcoming tasks, searches existing entries, and checks projects, areas, and tags. When adding a task, you can include notes, deadlines, tags, and a checklist. Existing tasks can be renamed, moved, marked complete, or canceled, and their notes can be extended.

When it helps

Use it to review your daily plans with an agent or collect work such as travel preparations into a project. It also helps you find tasks already registered in Things 3 and update their contents or status.

Example requests

  • “List today’s tasks and my inbox.”
  • “Add trip preparation to Travel, with Passport and Tickets as checklist items.”
  • “Find the task to buy milk and append a note.”

Notes

This skill is for macOS and requires the things command. If the database cannot be read, grant Full Disk Access to the app running the command. Updates require an authentication token. Use --dry-run to preview the URL for a change. Task deletion is not supported; delete tasks through the Things 3 interface.

Things 3 CLI

Use things to read your local Things database (inbox/today/search/projects/areas/tags) and to add/update todos via the Things URL scheme.

Setup

  • Install (recommended, Apple Silicon): GOBIN=/opt/homebrew/bin go install github.com/ossianhempel/things3-cli/cmd/things@latest
  • If DB reads fail: grant Full Disk Access to the calling app (Terminal for manual runs; OpenClaw.app for gateway runs).
  • Optional: set THINGSDB (or pass --db) to point at your ThingsData-* folder.
  • Optional: set THINGS_AUTH_TOKEN to avoid passing --auth-token for update ops.

Read-only (DB)

  • things inbox --limit 50
  • things today
  • things upcoming
  • things search "query"
  • things projects / things areas / things tags

Write (URL scheme)

  • Prefer safe preview: things --dry-run add "Title"
  • Add: things add "Title" --notes "..." --when today --deadline 2026-01-02
  • Bring Things to front: things --foreground add "Title"

Examples: add a todo

  • Basic: things add "Buy milk"
  • With notes: things add "Buy milk" --notes "2% + bananas"
  • Into a project/area: things add "Book flights" --list "Travel"
  • Into a project heading: things add "Pack charger" --list "Travel" --heading "Before"
  • With tags: things add "Call dentist" --tags "health,phone"
  • Checklist: things add "Trip prep" --checklist-item "Passport" --checklist-item "Tickets"
  • From STDIN (multi-line => title + notes):
    • cat <<'EOF' | things add -
    • Title line
    • Notes line 1
    • Notes line 2
    • EOF

Examples: modify a todo (needs auth token)

  • First: get the ID (UUID column): things search "milk" --limit 5
  • Auth: set THINGS_AUTH_TOKEN or pass --auth-token <TOKEN>
  • Title: things update --id <UUID> --auth-token <TOKEN> "New title"
  • Notes replace: things update --id <UUID> --auth-token <TOKEN> --notes "New notes"
  • Notes append/prepend: things update --id <UUID> --auth-token <TOKEN> --append-notes "..." / --prepend-notes "..."
  • Move lists: things update --id <UUID> --auth-token <TOKEN> --list "Travel" --heading "Before"
  • Tags replace/add: things update --id <UUID> --auth-token <TOKEN> --tags "a,b" / things update --id <UUID> --auth-token <TOKEN> --add-tags "a,b"
  • Complete/cancel (soft-delete-ish): things update --id <UUID> --auth-token <TOKEN> --completed / --canceled
  • Safe preview: things --dry-run update --id <UUID> --auth-token <TOKEN> --completed

Delete a todo?

  • Not supported by things3-cli right now (no "delete/move-to-trash" write command; things trash is read-only listing).
  • Options: use Things UI to delete/trash, or mark as --completed / --canceled via things update.

Notes

  • macOS-only.
  • --dry-run prints the URL and does not open Things.
