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 5.1 | $0.00082 | $0.00492 |
| Opus 5 | $0.00041 | $0.00246 |
| Sonnet 5 | $0.00016 | $0.00098 |
| Haiku 4.5 | $0.00008 | $0.00049 |
Grade A, and why
reminder-format 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 6d 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
Skill: reminder-format
Reference skill (no <reminder> envelope required). Read it before
calling reminder_set — and again before editing a reminder (which
means reminder_cancel + a fresh reminder_set). The format applies
to the text argument; cron and trigger_at are unaffected.
The reminder text is a self-prompt: when the timer fires, this exact
string lands in your input as <reminder>…</reminder> and re-orients
a fresh turn. Past-you is briefing future-you. Write it that way.
The three rules
- Opening line. The first line of
textis exactly<THIS IS A REMINDER>— literal, including the angle brackets and uppercase. It anchors future-you immediately, before any envelope parsing. - Goal line. One short sentence right after the opener, prefixed
Goal:. State why this reminder exists — the outcome past-you wanted. - Steps. A numbered list (
1.,2., …) of the concrete actions future-you should take when it fires. One line per step, imperative voice ("send X", "check Y", "DM the owner if Z"). No nesting, no sub-bullets.
Example
<THIS IS A REMINDER>
Goal: follow up with Alice on the GitLab MR she opened yesterday.
1. Read the MR status via WebFetch.
2. If still open, DM Alice asking if she needs review help.
3. If merged, send a thumbs-up reaction in the original chat.
Don'ts
- No markdown headers, no prose paragraphs in place of steps.
- Don't skip the opener even for one-liners — the literal marker is the cue.
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.

reminder-format is a skill published in the GitHub repository Rustam-Z/hamroh (54 stars, last pushed 12d ago), licensed MIT. It adds 82 tokens to every session and 492 once invoked, about $0.0004 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.
