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 | $0.00018 | $0.01168 |
| Opus 5 | $0.00009 | $0.00584 |
| Sonnet 5 | $0.00004 | $0.00234 |
| Haiku 4.5 | $0.00002 | $0.00117 |
Grade A, and why
email-drafting 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 7d 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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Email Drafting SOP
Goal
Write clear, professional emails that get read and acted upon. Match tone to context. Drive the desired outcome with minimal friction for the recipient.
Email Anatomy
Subject: [Category] Specific, actionable title
Hi [Name / Team],
[Opening: 1 sentence — context or reason for writing]
[Body: 2-4 sentences — the point, details, or ask]
[CTA: 1 clear ask or next step]
[Closing],
[Your name]
Subject Line Formulas
| Pattern | Example |
|---|---|
| Direct action | "Review needed: API proposal by Friday" |
| Question | "Quick question about Q3 roadmap scope" |
| FYI/update | "Update: auth migration completed" |
| Number | "3 options for the database decision" |
| Deadline | "Decision needed before Thursday standup" |
Rules:
- Under 50 characters where possible
- Put the most important word first
- Avoid "Hello", "Following up", "Just checking in" as openers
- Never use ALL CAPS
Tone Calibration
| Context | Tone | Avoid |
|---|---|---|
| Executive / C-suite | Concise, direct, no fluff | Long intros, excessive detail |
| Colleague / peer | Conversational, collaborative | Overly formal language |
| Client / external | Professional, warm | Jargon, internal acronyms |
| Vendor / support | Clear, factual, firm | Aggressive or passive |
| Sensitive topics | Empathetic, non-accusatory | Blame, assumptions |

Cold outreach
Subject: [Specific hook — their work, mutual connection, or shared interest]
Hi [Name],
[1 sentence: who you are + why you're reaching out — be specific, not generic]
[1-2 sentences: the value or relevance to them specifically]
[Clear, low-friction ask — not "let me know if you're interested" but a specific question or step]

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.

email-drafting is a skill published in the GitHub repository furkangonel/cowrangler (2 stars, last pushed yesterday), licensed MIT.
