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 B, and why

voice-dna-creator scanned grade B with 1 finding 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 13d 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.

Voice DNA Creator

Analyze writing samples to extract and codify a unique voice profile that AI can use to replicate your authentic writing style.

When to Use This Skill

  • Setting up a new writing system
  • Creating voice profiles for clients (ghostwriting)
  • Updating voice profiles after style evolution
  • Onboarding into content creation workflow

Requirements

The user must provide:

  • Minimum: 3 writing samples (500+ words each)
  • Ideal: 5-10 samples across different content types
  • Best: Mix of casual (social posts) and formal (articles) content

Analysis Process

Step 1: Collect Samples

Ask: "Please share 3-10 writing samples that represent your authentic voice. These can be:

  • Newsletter issues
  • Blog posts
  • Social media posts
  • Emails you've written
  • Any content where you feel 'this sounds like me'

Paste them here or point me to files."

Step 2: Analyze Core Elements

For each sample, analyze:

Personality Markers

  • What personality traits come through?
  • What's the energy level?
  • How does the writer relate to the reader?

Emotional Range

  • What emotions are expressed?
  • How intense are they?
  • What's the dominant emotional tone?

Communication Style

  • Formality level (casual to professional)
  • Sentence length patterns
  • Paragraph structure
  • Use of questions, commands, statements

Language Patterns

  • Signature phrases that repeat
  • Power words used frequently
  • Transition phrases
  • Opening and closing patterns

What They Avoid

  • Words or phrases never used
  • Tones never taken
  • Approaches avoided

Formatting Habits

  • Emoji usage
  • List usage
  • Header styles
  • Bold/italic patterns

Step 3: Synthesize Findings

Combine analysis across all samples to identify:

  • Consistent patterns (appear in most samples)
  • Contextual variations (change based on content type)
  • Core voice elements (never change)

Step 4: Generate Voice DNA

Create the profile following this structure:

{
  "voice_dna": {
    "version": "1.0",
    "last_updated": "YYYY-MM-DD",
    "core_essence": {
      "identity": "",
