Token cost

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	$0.00131	$0.02867
Opus 5	$0.00066	$0.01434
Sonnet 5	$0.00026	$0.00573
Haiku 4.5	$0.00013	$0.00287

Measured 10d ago against content hash cdfa6d2c3392, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-10, from the pricing page.

Security

Grade A, and why

saas-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 10d 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.

SaaS Email — E-posta Altyapısı

Bu skill, bir SaaS uygulamasının e-posta katmanını kurar. E-posta, kullanıcıyla iletişimin en kritik kanalıdır — magic link giriş, ödeme onayları, bildirimler ve destek hep e-postaya bağlıdır.

Bağımlılık: Bu skill saas-launcher orkestratör skill'inin Faz 5'idir. Bağımsız olarak da kullanılabilir.

Bağlı skill'ler:

saas-auth — Magic Link stratejisi bu skill'in altyapısına bağlıdır.
saas-payments — Ödeme bildirimleri (onay, hata, iptal) e-posta ile gönderilir.

Zamanlama notu: DNS kayıtlarının yayılması 24-48 saat sürebilir. E-posta altyapısını mümkün olduğunca erken — ideal olarak projenin ilk gününde — başlat. En azından DNS kayıtlarını ekle, servis tarafında doğrulamayı beklerken diğer fazlara devam et.

E-posta Servisi Seçimi

Resend — Varsayılan Önerimiz

Ne zaman seç: Çoğu SaaS projesi için. Modern API, React Email ile güzel şablonlar, Next.js ekosistemiyle doğal uyum.

Güçlü yönleri: API tasarımı basit ve modern, React Email ile tip güvenli şablonlar, webhook desteği, domain doğrulama dashboard'u anlaşılır, Next.js ve Vercel ile sorunsuz entegrasyon.

Zayıf yönleri: Ücretsiz katman günde 100 e-posta ile sınırlı (launch günü aşılabilir), inbound e-posta desteği sınırlı, görece yeni servis (Mailgun kadar olgun değil).

Fiyatlandırma: Ücretsiz katman (100/gün), ardından $20/ay (50K e-posta). Çoğu erken SaaS için yeterli.

Mailgun

Ne zaman seç: Yüksek hacimli gönderim, gelişmiş inbound e-posta routing, mevcut Mailgun altyapısı varsa.

Güçlü yönleri: Yüksek hacim desteği, güçlü inbound routing (gelen e-postaları webhook'la işle), olgun ekosistem, detaylı analitik.

Zayıf yönleri: API tasarımı eski, React Email desteği yok (HTML şablonları elle yazılmalı), kurulum daha karmaşık, EU ve US bölgeleri ayrı.

DNS Altyapısı — E-postanın Temeli

DNS kayıtları, e-postalarının spam yerine inbox'a düşmesini sağlayan teknik altyapıdır. Bu kayıtlar olmadan gönderilen e-postaların büyük çoğunluğu spam klasörüne gider veya hiç teslim edilmez.

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.
