SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Analyze and extract voice patterns from writing samples to create or update robust voice skills with measurable targets and authorship-matching validation. Use when calibrating a new voice, refining an existing voice profile, validating content against a voice profile, or comparing two voices. Do NOT use for content generation, general writing, or non-voice editing.

Core Features & Use Cases

  • Calibrate voice profiles from 50+ writing samples via deterministic scripts
  • Analyze writing samples to extract quantitative voice metrics (sentence length, punctuation, contractions)
  • Generate machine-readable profile.json with measurable targets and tolerances
  • Generate SKILL.md voice skills with sample-first architecture for authorship matching
  • Validate generated content against voice profile metrics
  • Show A/B comparisons between default and calibrated output

Quick Start

Collect 50+ writing samples from diverse sources and run the calibration workflow with your samples.

FAQPage Schema
How do I calibrate a voice profile from writing samples?

To calibrate a voice profile, you need to collect 50+ writing samples and run the deterministic calibration workflow, which extracts quantitative metrics like sentence length and punctuation to generate a machine-readable profile.

How does deterministic voice analysis work for authorship matching?

Deterministic voice analysis works by running scripts on writing samples to extract quantitative metrics, interpreting the results with AI, and validating the outputs against measurable targets to ensure accurate authorship matching.

Can I validate generated content against an existing voice profile?

Yes, you can validate generated content against a voice profile by comparing the content's metrics to the established tolerances, allowing you to verify authorship matching and perform A/B style comparisons between outputs.

What is the minimum number of writing samples needed for voice calibration?

Voice calibration requires a minimum of 50 writing samples from diverse sources to accurately extract quantitative voice metrics and generate a robust profile with measurable targets.

When should I not use voice calibration for content?

You should not use voice calibration for general content generation, general writing, or non-voice editing, as the workflow is specifically designed for creating, refining, and validating voice profiles.

What outputs do I get from a voice calibration workflow?

The voice calibration workflow outputs a machine-readable profile.json with measurable targets and tolerances, alongside a SKILL.md voice skill utilizing a sample-first architecture for authorship matching.
