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 | $0.00093 | $0.02449 |
| Opus 5 | $0.00046 | $0.01224 |
| Sonnet 5 | $0.00019 | $0.00490 |
| Haiku 4.5 | $0.00009 | $0.00245 |
Grade A, and why
marketing-email 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 — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Email Skill
You are helping the owner produce a complete, publishable marketing or sales email. The email must comply with the format guidelines in this skill folder, reflect the company's brand voice, and — if a campaign briefing is present — serve the briefing's goals.
This skill covers marketing email (bulk campaigns, newsletters, nurture sequences) and sales email (cold or warm 1:1 outreach) as two flavors of the same discipline. It does not cover everyday personal or internal professional correspondence. This skill is language-, industry-, and audience-neutral. It works for any output language and any B2B or B2C context. Calibration happens through the loaded context files, the campaign briefing (if any), and the owner's topic input.
Step 0: Recall learnings
If .claude/learnings.md exists, read it silently. Apply all relevant entries to
inform this run. Do not announce this step. If the file is absent, continue normally.
Step 1: Load context
Check for a ## Context files table in CLAUDE.md via:
grep -A 200 '## Context files' CLAUDE.md 2>/dev/null || echo "(no context table)"
CLAUDE.md files may exist at multiple hierarchy levels (workspace root, project root, sub-directory) and the harness loads all applicable ones. Where multiple tables exist, rows from more specific CLAUDE.md files take precedence.
Do not enumerate required categories by name. Context rows carry free-form, user-chosen labels — there is no schema of category names to match against. Instead, Read every file listed in the File column, then assess each row's Summary to work out what it covers, and map the loaded files to this skill's content needs:
| Need | What to look for in the Summary |
|---|---|
| Brand voice | Writing style, tone, vocabulary, phrasing rules, things to avoid |
| Organization background | Who the company/author is, products, positioning, mission |
| Target audience | Reader personas, goals, challenges, job titles, B2B/B2C signals |
| Output language | Default language, locale, or region |
| Email-specific rules | Signature/legal-footer requirements, send-cadence policy, CTA rules |
What ships with it
1 file 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.

marketing-email is a skill published in the GitHub repository clever-cc-plugins/cc-content (1 stars, last pushed 13d ago), licensed MIT. It adds 93 tokens to every session and 2,449 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
