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

account-security 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.

Account Security

Overview

Customer accounts hold saved payment methods, loyalty points, purchase history, and shipping addresses — making them high-value targets for credential-stuffing attacks and account takeovers. Effective account security layers brute-force protection on the login page, breach-exposed password detection, optional multi-factor authentication (MFA), and anomaly detection for account takeover patterns. The right approach depends heavily on your platform — Shopify manages most security controls at the platform level, while WooCommerce requires additional plugins.

When to Use This Skill

  • When building a customer account system from scratch
  • When auditing an existing account system for security weaknesses
  • When observing credential stuffing attacks (high login failure rates from distributed IPs)
  • When adding MFA as an optional or required layer for high-value customers
  • When implementing "Sign in with Google/Apple" as a more secure alternative to passwords

Core Instructions

Step 1: Understand your platform's security model

Platform What the Platform Handles What You Need to Configure
Shopify SSL/TLS, brute-force protection on login, PCI compliance, server-side security Customer account settings, whether to require phone verification, Social login apps for Google/Apple sign-in
WooCommerce Basic login form only Install Wordfence (free) for brute-force protection, limit login attempts, 2FA, and login security monitoring
BigCommerce SSL/TLS, platform-managed account security, basic brute-force protection Two-factor authentication for admin users; customer-facing 2FA requires an app
Custom / Headless Nothing — you build all security controls Rate limiting, password hashing, MFA, session management, ATO detection

Step 2: Platform-specific account security setup


Shopify

Shopify handles the majority of customer account security at the platform level — you do not manage SSL, brute-force detection, or password hashing yourself.
