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 | $0.00127 | $0.01632 |
| Opus 5 | $0.00063 | $0.00816 |
| Sonnet 5 | $0.00025 | $0.00326 |
| Haiku 4.5 | $0.00013 | $0.00163 |
Grade A, and why
newsletter-welcome-sequence 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.
How it starts
The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build A Welcome Sequence That Turns Subscribers Into Fans
Write a complete 5-email welcome sequence that establishes trust, delivers value, and primes new subscribers to become customers.
Why This Sequence Works
The first 5–7 days after someone subscribes are the highest-engagement window you'll ever have. New subscribers are curious, paying attention, and ready to act.
This 5-email sequence is engineered to:
- Make a great first impression
- Demonstrate your value immediately
- Build trust through expertise and story
- Introduce your paid offer naturally — without being pushy
The 5-Email Framework
| # | Purpose | |
|---|---|---|
| 1 | The Warm Welcome | Set expectations, encourage immediate engagement |
| 2 | The Greatest Hits | Showcase best content, demonstrate value |
| 3 | The Biggest Mistake/Misconception | Challenge assumptions, position expertise |
| 4 | The Origin Story | Build personal connection through your journey |
| 5 | The Soft Sales Pitch | Introduce an offer naturally |
Workflow
- Interview the user (questions below) — one at a time
- Write all 5 emails using the frameworks below
- Present them clearly labeled and ready to copy/paste
Interview Questions
Ask these one at a time — do NOT front-load all questions:
- What's your name and newsletter name?
- What's your niche/industry and target audience?
- What are 2–3 main pain points your audience deals with?
- What are 2–3 outcomes/goals your audience wants?
- How often do you send your newsletter?
- How many subscribers do you have? (for social proof)
- What are 3–5 of your best content pieces or resources? (titles + one-line descriptions)
- What's a common misconception or mistake in your industry that you disagree with?
- What's your unique framework or approach that counters it?
- What are the key moments of your origin story? (bullet points are fine)
- What credentials or results establish your authority?
- What paid offer will you soft-pitch in Email 5?
- What simple action do you want subscribers to take in Email 1? (e.g., "reply with the word READY")
- What do they get for taking that action? (e.g., "a bonus PDF guide")
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.
