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 | $0.00118 | $0.01354 |
| Opus 5 | $0.00059 | $0.00677 |
| Sonnet 5 | $0.00024 | $0.00271 |
| Haiku 4.5 | $0.00012 | $0.00135 |
Grade A, and why
e-blast-newsletter scanned grade A with 1 finding 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 12d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
6. Windows에서 API 호출은 Python urllib + utf-8 (curl+cp1252 이모지 크래시). How it starts
The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Resend Email
Resend 하나로 트랜잭셔널 메일 + 뉴스레터(브로드캐스트)를 처리한다. Free 티어: $0, 월 3,000통, 일 100통, 도메인 1개 — 소규모 뉴스레터는 무료로 충분하다. (검증: resend.com/pricing, 2026-07-16)
Hard rules
- 발송은 유저 게이트 — "작성해줘"는 발송 승인이 아니다. 브로드캐스트는 반드시 초안 상태로 만들어 유저 확인 후 send.
- 브로드캐스트에는
{{{RESEND_UNSUBSCRIBE_URL}}}필수 — 수신거부 링크 없는 마케팅 메일은 스팸법 위반(CAN-SPAM/개인정보보호법). - 본발송 전 셀프 테스트 — 자기 주소로 1통 보내 렌더링/링크/머지태그 확인.
- 일 100통 제한(Free) — 100명 넘는 리스트는 일 단위 분할 또는 Pro($20/mo, 5만통) 업그레이드를 유저에게 안내.
- 콜드 아웃리치 금지 — Resend는 permission 기반. 콜드메일은 별도 도메인 + 전용 툴로 (b2b-cold-email).
- Windows에서 API 호출은 Python urllib + utf-8 (curl+cp1252 이모지 크래시).
- 제목은 A/B 전제 — 브로드캐스트마다 제목 후보 3개(다른 축: 숫자/질문/ 직설)를 만들어 유저가 고르고, 리스트가 1,000+ 이면 오디언스를 세그먼트로 나눠 실제 A/B 발송 → 오픈율 승자를 다음 호 기본 축으로. 히어로 이미지가 있으면 image-gen 스킬로 변형 2–3개.
Setup (1회)
- resend.com 가입 → API Keys → env
RESEND_API_KEY(re_...) 저장. - 도메인 인증: Dashboard → Domains → Add (또는
POST /domains) → 발급된 SPF/DKIM DNS 레코드를 도메인 DNS에 추가 → Verify.from은 인증된 도메인의 주소만 가능 (뉴스레터 <[email protected]>). - Base
https://api.resend.com,Authorization: Bearer $RESEND_API_KEY. - VERIFY:
GET /domains에 status "verified".
A. 트랜잭셔널 (1:1)
POST /emails
{ "from": "Acme <[email protected]>", "to": ["[email protected]"],
"subject": "...", "html": "..." }
- 대량 개별 발송:
POST /emails/batch— 한 번에 최대 100개 객체. reply_to,cc,bcc,attachments지원.
B. 뉴스레터 (Audience + Broadcast)
# 1) 오디언스 생성 (리스트당 1개)
POST /audiences { "name": "Newsletter" }

# 4) 유저 승인 후 발송 (즉시 또는 예약)

POST /broadcasts/{id}/send { "scheduled_at": "2026-07-20T09:00:00+09:00" }
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.

e-blast-newsletter is a skill published in the GitHub repository crealwork/ai-marketing-kit (18 stars, last pushed 1mo ago), licensed MIT. It adds 118 tokens to every session and 1,354 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
