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

visual-regression-testing 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 3d 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.

  • Generates actionable monitoring & alerts frameworks based on your specific business context
  • Works across major e-commerce platforms (Amazon, Shopify, Walmart, WooCommerce, Etsy, TikTok Shop)
  • Provides data-driven recommendations with industry benchmarks
  • Outputs ready-to-implement plans, not just generic advice

Install

Usage

Input: Website URL, critical pages, device/viewport targets

Output: Visual test suite design, screenshot comparison rules, mobile check checklist, anomaly alerting config

Example Prompt

"I run a [your business type] on [platform]. Help me set up visual regression testing for my business. Here's my current situation: [describe context]."

Limitations

  • Requires your specific business data for accurate recommendations
  • Market benchmarks are based on US/EU data — adjust for other regions

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.
