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

validate-style-guide 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 5d 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.

Validate Style Guide

Check the $1 style guide for internal contradictions, completeness, and quality issues.

Step 1: Load Style Guide

  • Read style guide from brands/$1/style-guide.md
  • If not found: Error and suggest running /generate-style-guide $1 [source]
  • Parse the document into 8 sections
  • Extract all rules, examples, and exceptions

Step 2: Run Completeness Checks

Required Sections

  • Section 1: Voice & Tone
  • Section 2: Grammar & Usage
  • Section 3: Punctuation
  • Section 4: Formatting
  • Section 5: Technical Standards
  • Section 6: Content Patterns
  • Section 7: Industry-Specific Terms
  • Section 8: Quick Reference Checklist

For each section, verify:

  • Section header exists
  • At least 3 subsections present
  • At least 5 rules per section
  • Each rule has at least one example

Rule Count

  • Count total rules across all sections
  • Target: 50+ rules
  • Warning if <50 rules: "Style guide may be incomplete"
  • Critical if <30 rules: "Style guide needs expansion"

Example Coverage

  • Count rules with examples
  • Target: 90%+ rules should have examples
  • Flag rules missing examples

Step 3: Run Consistency Checks

Cross-Section Contradictions

Check for rules that contradict each other across sections:

Common contradiction patterns to detect:

  • Section 1 (Voice) says "use contractions" but Section 2 (Grammar) says "avoid contractions"
  • Section 3 (Punctuation) says "em dash with spaces" but examples show without spaces
  • Section 4 (Formatting) heading case rule conflicts with Section 2 capitalization rule
  • Section 5 (Technical) date format conflicts with examples in other sections

Example Consistency

  • Check that DO examples don't appear in DON'T sections
  • Verify examples follow the rules they illustrate
  • Flag contradictory examples

Terminology Consistency

  • Extract all defined terms from Section 7
  • Check if same terms are used consistently throughout document
  • Flag inconsistent capitalization of product/brand names

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.
