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.

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 | $0.00041 | $0.01340 |
| Opus 5 | $0.00020 | $0.00670 |
| Sonnet 5 | $0.00008 | $0.00268 |
| Haiku 4.5 | $0.00004 | $0.00134 |
Grade A, and why
welcome-email-writer 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 8d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Welcome Email Writer
What This Skill Does
Writes the automated welcome email that new subscribers receive immediately after signing up, establishing the newsletter's voice, making the editorial promise concrete, and setting expectations that reduce early unsubscribes.
When To Use This Skill
- You are launching a new newsletter and need a welcome email before your first subscriber arrives
- Your current welcome email is the default platform auto-reply ("Thanks for subscribing!") and you are losing early subscribers
- You have rebranded or significantly changed editorial direction and need a welcome email that reflects the new positioning
- You are building a paid newsletter and need a welcome sequence that primes free subscribers for eventual upgrade
What You Need To Provide
Required: Newsletter name and a 2–3 sentence description of what it covers and for whom; the publishing cadence (daily, weekly, etc.); the newsletter's tone and voice in your own words Optional: What prompted you to start the newsletter (if personal origin helps the voice); what you want subscribers to do immediately after reading (reply, whitelist, follow on social, etc.); any paid tier details if applicable; one concrete example of the type of story or insight a subscriber can expect
How the Assistant Approaches This
- Opens with a brief, human acknowledgment of the subscription — not "You've been added to our list" but something that recognises the reader made a deliberate choice and honours that
- Delivers the editorial promise in specific, concrete terms: not "we cover the media industry" but "every Monday we give you the one story the media industry spent the week avoiding"; the specificity is what converts a vague interest into an expectation the reader will look forward to
- Sets practical expectations: cadence, typical length, what a reader should do if they miss issues (archive links, search tips), and any important logistical notes (whitelist instructions if the newsletter has deliverability issues)
- Ends with a single, clear call to action — ideally one that invites a reply, because early replies dramatically improve deliverability by signalling to email providers that the newsletter is wanted

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.
