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

tasks 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.

Tasks

Use the external things binary via blue exec to read and update a real Things 3 task list on macOS.

Setup

Install the CLI if needed:

blue exec command='GOBIN=/opt/homebrew/bin go install github.com/ossianhempel/things3-cli/cmd/things@latest'

Sanity-check the install:

blue exec command='things --help'

If database reads fail, grant Full Disk Access to the calling app (for example Terminal or your IDE).

Optional environment:

  • THINGSDB or --db to point at a specific ThingsData-* folder
  • THINGS_AUTH_TOKEN to avoid passing --auth-token for update operations

Task Routing

User Intent Action
Read inbox/today/upcoming/search/projects in Things 3 blue exec command='things ...'
Add or update real tasks in the user's Things database blue exec command='things add ...' / blue exec command='things update ...'
User wants a reminder/alert notification Use reminder, not tasks
User wants recurring command automation Use scheduler, not tasks
User only needs an in-chat checklist or plan Prefer normal chat output or the plan skills, not tasks

Command Usage

Read from Things:

blue exec command='things inbox --limit 50'
blue exec command='things today'
blue exec command='things upcoming'
blue exec command='things search "query"'
blue exec command='things projects'

Add tasks:

blue exec command='things --dry-run add "Title"'
blue exec command='things add "Title" --notes "..." --when today --deadline 2026-01-02'
blue exec command='things add "Book flights" --list "Travel"'
blue exec command='things add "Call dentist" --tags "health,phone"'

Update tasks (auth token required):

blue exec command='things search "milk" --limit 5'
blue exec command='things update --id <UUID> --auth-token <TOKEN> --completed'
blue exec command='things update --id <UUID> --auth-token <TOKEN> --notes "New notes"'

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.
