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.

SkillSpector: 6 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00070 | $0.01957 |
| Opus 5 | $0.00035 | $0.00979 |
| Sonnet 5 | $0.00014 | $0.00391 |
| Haiku 4.5 | $0.00007 | $0.00196 |
Grade A, and why
cold-email-weekly-rhythm 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 13d 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.

Cold Email Weekly Rhythm
Having 29 cold email skills doesn't help if you don't run them on a schedule. This is that schedule.
This is a pure playbook. No scripts, no automatic reminders. You put the rhythm on your own calendar (Step 1 below) and run the prescribed skill at the prescribed time. That's the entire system.
Step 1 (required before using this skill): Put the rhythm on your calendar
Open Google Calendar / Outlook / Apple Reminders / whatever you actually look at every day. Create these as recurring events. Copy the titles and cadences exactly.
| Event title | Cadence |
|---|---|
| Cold email: Monday deliverability audit | Every Monday, 9:00 am |
| Cold email: Wednesday positive-reply sweep | Every Wednesday, 10:00 am |
| Cold email: Friday campaign retrospectives | Every Friday, 3:00 pm |
| Cold email: Inbox rotation | Every other Monday, 11:00 am |
| Cold email: Monthly spam placement test | 1st of each month, 10:00 am |
| Cold email: Quarterly experiment review | First Monday of each quarter, 1:00 pm |
Do not skip Step 1. The difference between hobbyist and top-1% cold email operators is that the top-1% operators actually run these tasks on their declared cadence, week after week. Your calendar is the accountability system. This skill doesn't have a built-in reminder — intentionally — because if it did and it broke, your ops would silently fail.
Monday — Deliverability audit (15 min)
Run:
/email-deliverability-audit --days=7
(If using the scoped version: audit-performance.ts --campaign-ids=<active campaign ids> --days=7)
Review:
- Fleet reply rate over last 7 days — must be ≥1% (the 1% rule)
- Flagged campaigns (
flag_low_reply = TRUE) - Flagged inboxes (
flag_high_bounce = TRUE)
Action:
- If any campaign failed the 1% rule: run
/deliverability-incident-response→ triage decision tree - If bounce rate spiked above 2%: pause the offending campaign immediately, then triage
- If everything clean: log the check in a weekly journal, close the tab
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.

cold-email-weekly-rhythm is a skill published in the GitHub repository growthenginenowoslawski/coldoutboundskills (702 stars, last pushed 25d ago), licensed MIT. It adds 70 tokens to every session and 1,957 once invoked, about $0.0003 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.
