    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

things-mac scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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; Otto.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.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
