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 | $0.00078 | $0.02748 |
| Opus 5.5 | $0.00031 | $0.01099 |
| Sonnet 5.5 | $0.00016 | $0.00550 |
| Haiku 4.5 | $0.00008 | $0.00275 |
Grade A, and why
email-write 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.

Email Write Sub-Skill
Purpose
Generate professional, high-converting email copy using proven copywriting frameworks. Produces subject line variants with scoring, responsive HTML templates with dark mode support, plain-text fallback, and preheader recommendations.
Activation
This sub-skill is invoked by the main /email skill when the user needs to compose a new email.
Workflow
1. Gather Context
First, check if email-profile.md exists in the project directory. If yes, load business type, tone preferences, and target audience from the profile.
If no profile exists or user provides new context, ask for:
- Email Purpose: cold outreach, newsletter, product launch, promotional, re-engagement, welcome, feature announcement, etc.
- Recipient: name, role, relationship (new lead, existing customer, subscriber, team member)
- Tone: professional, friendly, casual, authoritative, empathetic, enthusiastic
- Business Type: (from profile or ask) SaaS, e-commerce, service business, agency, creator, B2B, B2C
- Key Message: what action should the recipient take?
- Additional Context: product details, promotion details, deadline, personalization data
2. Select Copy Framework
Based on the email purpose, choose the appropriate framework from references/copy-frameworks.md:
| Email Purpose | Recommended Framework | Why |
|---|---|---|
| Cold outreach | PAS | Empathy-driven, addresses pain points |
| Product launch | AIDA | Builds excitement, drives action |
| Newsletter | BAB or AIDA | Aspirational or engaging storytelling |
| Feature announcement | FAB | Clear value proposition for features |
| Promotional/sale | AIDA | Creates desire and urgency |
| Re-engagement | PAS | Identifies problem of disengagement |
| Welcome email | BAB | Shows transformation journey |
| Case study | 4Ps | Proof-heavy, testimonial-driven |
| Review request | PAS | Empathetic ask for feedback |
| Appointment reminder | Direct | No framework needed |
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.
