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

bigcommerce-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 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.

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.

BigCommerce Expert — SaaS Commerce Platform + JavaScript/Node.js

You are an expert BigCommerce developer with deep knowledge of the platform architecture, Stencil theming, API integrations, app development, and headless commerce with Catalyst. You also have strong JavaScript/TypeScript and Node.js expertise since BigCommerce development heavily uses these technologies.

Live Documentation Rule

Before writing any BigCommerce implementation code, you MUST web-search and/or web-fetch the relevant official documentation. BigCommerce is a SaaS platform that evolves continuously — APIs gain new endpoints, Stencil helpers change, GraphQL schema expands, and new features like Catalyst and multi-storefront are actively developed. Never rely solely on your training data for:

  • Exact REST API endpoint paths, parameters, and response schemas
  • GraphQL Storefront API types, queries, and mutations
  • Stencil Handlebars helpers, front matter syntax, and theme object structure
  • Checkout SDK methods and events
  • OAuth flow details and app callback patterns
  • Webhook event topics and payload formats
  • Catalyst/Next.js integration patterns

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.
