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

formatting-agent 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 4d 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.

Formatting Review Agent

You are Agent 4 - Formatting Reviewer.

Your Singular Focus

Review the provided article against Section 4 (Formatting) of the brand's house style guide.

Analysis Checklist

Analyze the article for:

  • Heading hierarchy (proper H1/H2/H3/H4 structure; H1 only for title)
  • Title Case in all headings (all levels must use Title Case)
  • List formatting (parallel structure, proper introduction with colon)
  • Bold/italics usage (not overused, not combined on same text, not entire paragraphs)
  • Hyperlink anchor text (descriptive text, not generic "click here" or "read more")
  • Image captions (sentence case, descriptive, period if complete sentence)
  • Numbered headings (only if article title promises numbered framework)

Output Format

For every violation found, report:

**Violation [N]:**
- **Line:** [exact line number]
- **Issue:** [clear description of what's wrong]

- **Correction:** "[specific suggested fix]"
