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.

Security

Grade A, and why

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 6d 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 — Email & Notification Systems

Activate When

  • User invokes /godmode:email
  • User says "send emails", "email templates"
  • User says "notification system", "push notifications"
  • User says "bounce handling", "deliverability"
  • Application needs email or notification infrastructure

Workflow

Step 1: Requirements Discovery

# Detect existing email infrastructure
grep -r "resend\|sendgrid\|aws-sdk.*ses\|postmark" \
  package.json pyproject.toml go.mod 2>/dev/null

# Find existing templates
find . -path ./node_modules -prune -o \
  -name "*.mjml" -o -name "*.email.tsx" \
  -o -path "*/emails/*" 2>/dev/null | head -20

# Check for queue system
grep -r "bullmq\|bull\|sqs\|celery" \
  package.json pyproject.toml 2>/dev/null
NOTIFICATION REQUIREMENTS:
  Channels: Email | Push | SMS | In-app
  Email types: Auth (critical) | Transactional (high)
    | Product (medium) | Marketing (low)
  Volume: Trans <N>/day, Marketing <N>/month
  Compliance: CAN-SPAM, GDPR, CASL

IF no queue system: add one (never send sync)
IF no provider: recommend based on needs
IF no DNS auth: set up SPF/DKIM/DMARC

Step 2: Email Service Selection

| Feature     | SendGrid | SES    | Postmark | Resend |
|-------------|----------|--------|----------|--------|
| Best for    | Full feat| Volume | Transact | Dev DX |
| Free tier   | 100/day  | 62K/mo | 100/mo   | 3K/mo  |
| Delivery    | Good     | Good   | Excellent| Good   |
| Templates   | Yes      | SES v2 | Yes      | React  |

IF startup/dev-focused: Resend (best DX)
IF high-volume transactional: Postmark
IF full marketing + transactional: SendGrid
IF AWS-native / cost-sensitive: SES

Step 3: Email Template Design

EMAIL DESIGN CHECKLIST:
  Layout: single column, max 600px, large tap targets
  Content: plain text version, alt text on images
  Legal: visible unsubscribe, physical address
  Technical: inline CSS, table layout (Outlook)
  Deliverability: authenticated from-address,
    List-Unsubscribe header, text:image > 60%

THRESHOLDS:
  Max email size: 100KB (incl. HTML + inline CSS)
  Image hosting: CDN only, no base64 in email
  Preheader text: 40-130 characters

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.
