Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00023 | $0.00743 |
| Opus 5 | $0.00012 | $0.00371 |
| Sonnet 5 | $0.00005 | $0.00149 |
| Haiku 4.5 | $0.00002 | $0.00074 |
Grade A, and why
things-todo 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Things Todo
Use this for Things 3 tasks on Peter's Macs. Prefer things for Things-backed
todos; use $reminders only when the user asks for Apple Reminders.
Tool
- CLI:
things - Repo:
https://github.com/ossianhempel/things3-cli - Install:
GOBIN=/opt/homebrew/bin go install github.com/ossianhempel/things3-cli/cmd/things@latest
Auth for update URL operations:
source ~/.profile >/dev/null 2>&1 || true
things auth
THINGS_AUTH_TOKEN should come from ~/.profile or 1Password. Never print it.
things update --dry-run must redact it as auth-token=***.
Start
Use JSON for scripted reads and verification:
things tasks --format json --limit 20
things today --format json
things search "query" --format json
Things DB reads may need Full Disk Access for the calling app. Writes should go
through Things URL Scheme or AppleScript via things; do not write the SQLite DB
directly.
Add
Default: add, then search/read back.
things add "Book LHR-SFO nonstop business flight" --notes "Nonstop only." --when tomorrow --tags travel
things tasks --search "LHR-SFO" --format json
Useful flags:
--notes "text"--when today|tomorrow|evening|anytime|someday|YYYY-MM-DD--deadline YYYY-MM-DD--list "Project or Area"--tags tag1,tag2--checklist-item "text"repeatable--dry-runto inspect thethings:///URL without mutating.
Update / Delete
Find the UUID first, then mutate by id:
things tasks --search "flight" --format json
things update --id <uuid> "New title" --notes "Updated notes"
things tasks --search "New title" --format json
things delete --id <uuid> --confirm <uuid>
things tasks --search "New title" --format json
things trash --search "New title" --format json
Always read back after writes. Delete moves items to Things Trash; verify normal search is empty and trash search contains the item when cleanup matters.
Conventions
- Turn vague asks into concrete next-action titles.
- Preserve wording when the user clearly wants capture, not rewriting.
- Split unrelated actions into separate to-dos.
- Use Today only when the user implies it; otherwise use Inbox/Anytime defaults.
- Prefer
--dry-runbefore bulk updates/deletes. - For current date math, run
date; do not guess.
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.
- 2d ago First seen · 97 lines · 23 tokens per session scan A a0e7d04daabc
things-todo is a skill published in the GitHub repository steipete/agent-scripts (6,590 stars, last pushed today), licensed MIT. It adds 23 tokens to every session and 743 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
