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 THINGSAUTHTOKEN 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 THINGSAUTHTOKEN or pass --auth-token
  • Title: things update --id --auth-token "New title"
  • Notes replace: things update --id --auth-token --notes "New notes"
  • Notes append/prepend: things update --id --auth-token --append-notes "..." / --prepend-notes "..."
  • Move lists: things update --id --auth-token --list "Travel" --heading "Before"
  • Tags replace/add: things update --id --auth-token --tags "a,b" / things update --id --auth-token --add-tags "a,b"
  • Complete/cancel (soft-delete-ish): things update --id --auth-token --completed / --canceled
  • Safe preview: things --dry-run update --id --auth-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.
