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 | $0.00000 | $0.02410 |
| Opus 5 | $0.00000 | $0.01205 |
| Sonnet 5 | $0.00000 | $0.00482 |
| Haiku 4.5 | $0.00000 | $0.00241 |
Grade A, and why
form-wiring 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 5d 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 — 395 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SKILL 4: Form Wiring
Connect your generated website to Resend for email delivery and Beehiiv for newsletter signup.
Overview
This skill transforms form placeholders in your site-generator output into fully functional forms that:
- Send contact inquiries via Resend
- Capture newsletter signups in Beehiiv
- Validate input client-side
- Handle errors gracefully
- Show success confirmations
- Protect against spam
What This Skill Does
1. Detects Forms
- Scans generated website files
- Identifies contact forms, newsletter fields, inquiry forms
- Finds Beehiiv embed placeholders
2. Creates Serverless Functions
- Generates
api/contact.tsorapi/contact.js - Implements Resend email delivery
- Handles multiple form types (contact, inquiry, etc.)
- Includes error handling and validation
3. Enhances Client-Side Forms
- Adds form validation (required, email, phone)
- Implements toast notifications (success/error)
- Adds honeypot field for spam protection
- Wires form submit to serverless function
- Adds loading states to buttons
4. Configures Services
- Resend API integration
- Beehiiv embed setup (zero-code iframe)
- Vercel environment variables
- Domain verification for Resend
Skill Workflow
Input
- Website folder (generated by site-generator)
- User's Resend API key (provided by user)
- User's Beehiiv publication ID (if using newsletter)
Processing
- Scan for form markup in HTML/JSX files
- Create
api/contact.tsserverless function - Add form submission handler in main JS
- Inject toast notification UI
- Generate environment variable setup instructions
- Create Beehiiv embed code
Output
- Updated website with wired forms
api/contact.tsserverless function- Updated form HTML with event listeners
.env.examplefile with required variables- Setup instructions for Vercel
- Beehiiv embed code (copy-paste ready)
Form Types Supported
Contact Form
Purpose: General inquiries from visitors
Fields:
- Name (required, text)
- Email (required, email)
- Subject (required, text)
- Message (required, textarea)
- Honeypot field (hidden)
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.

form-wiring is a skill published in the GitHub repository mrhinkle/VibeCoding-a-Website (11 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,410 tokens. 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.
