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 | $0.00121 | $0.02369 |
| Opus 5.5 | $0.00048 | $0.00948 |
| Sonnet 5.5 | $0.00024 | $0.00474 |
| Haiku 4.5 | $0.00012 | $0.00237 |
Grade A, and why
email-sequences 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 1mo 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 — 283 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Email Sequences
Plan and write email campaigns. Sequences (multi-message flows triggered by events) and broadcasts (one-off sends). Stack-agnostic. Works with any email service provider.
When to use
- Writing welcome and onboarding email sequences
- Planning lifecycle campaigns (activation, retention, win-back)
- Writing transactional emails (receipts, password resets, notifications)
- Newsletter design and writing
- Abandoned-cart or re-engagement flows
- Writing a one-off broadcast, launch announcement, or news email
- Drafting email subject lines and preview text for any send
When NOT to use
- Landing pages and conversion pages (use
landing-page-copy) - Long-form articles (use
content-and-copy) - Brand voice work (use
brand-voice) - Analytics setup for email (use
analytics-strategy)
Required inputs
- The audience (segment or list)
- The trigger or context (signup, purchase, abandonment, time-based, manual)
- The goal of the email or sequence
- Brand voice
- Any technical constraints (provider, deliverability requirements)
If the audience is undefined, define it before writing. Generic emails to "everyone" perform worse than targeted ones.
The framework: 6 sequence types
Most email programs run a handful of standard sequence patterns. Each has its own goals, structure, and pitfalls.
1. Welcome / onboarding
Triggered by signup. Goal: get the user to first value.
Typical structure (5 emails over 14 days):
- Email 1 (immediate): Welcome. Confirm they're in. State what happens next. Single CTA: the next obvious action.
- Email 2 (day 1 or 2): First-value step. Help them get to a quick win or core action.
- Email 3 (day 4 or 5): Education. Show them something they probably haven't discovered yet.
- Email 4 (day 8): Social proof. Customer story or use case relevant to their segment.
- Email 5 (day 14): Outcome reminder. Where they could be in 30/60/90 days. Soft commercial cue.
Common failure: Front-loading product features. Users don't care about features yet; they care about getting to value.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
