At a glance

Manage Things 3 via the things CLI on macOS (add/update projects+todos via URL scheme; read/search/list from the local Things database).

  • A user asks OpenClaw to add a task to Things
  • Calls go; needs THINGS_AUTH_TOKEN
  • List inbox/today/upcoming
  • Inspect projects/areas/tags

What it does

Things Mac is an agent skill from trpc-group/trpc-agent-go. Manage Things 3 via the things CLI on macOS (add/update projects+todos via URL scheme; read/search/list from the local Things database). Use when a user asks OpenClaw to add a task to Things, list inbox/today/upcoming, search tasks, or inspect projects/areas/tags.

Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Email management. It works with macOS. The repository describes itself as: A Go framework for building production agent systems with graph workflows, tools, memory, A2A, AG-UI, MCP, evaluation, and observability. The licence is Apache-2.0.

When your agent uses it

  • A user asks OpenClaw to add a task to Things
  • List inbox/today/upcoming
  • Inspect projects/areas/tags

Example prompts

  • “/things-mac”

Requirements

  • A credential in THINGS_AUTH_TOKEN

What it can do on your machine

Read from SKILL.md and the folder at commit 9bb1c42. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • go

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • THINGS_AUTH_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Things Mac loads about 888 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 340 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~888

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Manage Things 3 via the `things` CLI on macOS (add/update projects+todos via URL scheme; read/search/list from the local Things database). Use when a user asks OpenClaw to add a task to Things, list inbox/today/upcoming, search tasks, or inspect projects/areas/tags.

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.
