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.

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 | $0.00065 | $0.03687 |
| Opus 5 | $0.00032 | $0.01843 |
| Sonnet 5 | $0.00013 | $0.00737 |
| Haiku 4.5 | $0.00006 | $0.00369 |
Grade A, and why
email-notification-expert 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 9d 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

Email & Notification Expert (2026 Edition)
English
Orchestration & Integration
Connects and orchestrates with relevant domain skills like brainstorming, zero-to-prod-orchestrator, and project-context-mapper to ensure cohesive execution.
Description
Production-grade guide for building reliable email delivery systems and unified notification pipelines. Covers Resend, Postmark, AWS SES, React Email / MJML template engines, email deliverability (SPF, DKIM, DMARC), in-app notification systems (bell icon, toast, notification center), webhook-triggered email flows, email queuing with BullMQ/Inngest, and CAN-SPAM/GDPR compliance.
Trigger Conditions
Activate this skill when:
- Setting up transactional email (welcome, password reset, invoices, team invites).
- Building email templates with React Email or MJML.
- Integrating Resend, Postmark, SendGrid, or AWS SES.
- Implementing in-app notification systems (real-time bell, toast, notification center).
- Configuring email deliverability (SPF, DKIM, DMARC records).
- Building email queue systems for high-volume sends.
- Implementing unsubscribe management and compliance.
Email Provider Selection Guide
| Provider | Best For | Key Strength | Pricing Model |
|---|---|---|---|
| Resend | Modern apps, React Email | Developer DX, React components as email | Per email (free tier: 3k/mo) |
| Postmark | Transactional-only | Industry-best deliverability, dedicated IP | Per email (free tier: 100/mo) |
| AWS SES | High volume, cost-sensitive | Cheapest at scale ($0.10/1000 emails) | Per email |
| SendGrid | Marketing + Transactional | Full marketing suite, analytics | Tiered plans |
| Plunk | Self-hostable, open-source | Full control, no vendor lock-in | Free (self-hosted) |
Recommendation: Use Resend for most new projects (best DX with React Email). Use Postmark for mission-critical transactional emails. Use AWS SES for high-volume (10k+/day) cost optimization.
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-notification-expert is a skill published in the GitHub repository roedyrustam/vibes-plug (50 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 3,687 once invoked, about $0.0003 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 2026-08-30.
