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 | $0.00217 | $0.07912 |
| Opus 5.5 | $0.00087 | $0.03165 |
| Sonnet 5.5 | $0.00043 | $0.01582 |
| Haiku 4.5 | $0.00022 | $0.00791 |
Grade A, and why
grow-payment-gateway 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 1mo 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.

Grow Payment Gateway (Meshulam)
Overview
Grow (formerly Meshulam) is one of Israel's leading payment gateways, powering thousands of businesses with credit card processing, Bit payments, Apple Pay, Google Pay, and more. Unlike other Israeli gateways, Grow offers a unified API (the "Light API") that covers payment pages, tokenization, recurring billing, payment links, invoices, and webhooks in a single integration.
This skill guides integration with Grow's Light API for the full payment lifecycle: accepting payments, saving tokens for recurring charges, creating payment links for invoices, processing refunds, and handling real-time webhook notifications.
Official docs: https://developers.grow.business/
Developer support: [email protected] (carried from an earlier cycle; not confirmed against Grow's published documentation this cycle, so confirm it in your merchant portal before relying on it).
Instructions
Step 1: Understand Grow's Authentication
Grow uses three credentials provided during merchant onboarding:
| Credential | Purpose | Notes |
|---|---|---|
userId |
Merchant identifier | Unique per business account |
pageCode |
Payment page configuration | Different page codes for different payment types (credit card, Bit, recurring, etc.) |
apiKey |
API authentication | Required when managing multiple businesses or specific configurations |
Environments:
| Environment | Base URL |
|---|---|
| Sandbox (testing) | https://sandbox.meshulam.co.il |
| Production | https://secure.meshulam.co.il |
Critical: Server-side only. All API requests must originate from your server. Client-side (browser) requests are blocked by Grow.
Critical: FormData format. All request bodies use multipart/form-data, NOT JSON. If you send application/json the API does not parse your fields at all, so you get a misleading validation error about a missing or invalid field rather than a content-type error.
What ships with it
9 files 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.
