deep-voice-analysis

deep-voice-analysis is a skill for Claude Code, Codex from Ckokoski/AuthorAgent. It costs 26 tokens per session (1,391 once invoked), scanned A, original, MIT.

A writing-analysis tool that examines your text across 47 patterns, such as sentence rhythm, paragraph length, vocabulary, and repeated words, to create a profile of your writing style.

In plain words
What is it for?
Use it to study your existing writing and document the patterns that make your style recognisable.
Why use it?
It helps capture writing habits that a basic style check may miss, so later text can be compared with a more detailed picture of your voice.

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

deep-voice-analysis 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 6d 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.

Deep Voice Analysis — Premium Skill

Advanced writing voice analysis that goes far beyond the free style-clone skill. Analyzes your writing across 47 markers to create a forensic-level Voice Profile.

What Makes This Different From the Free Style-Clone Skill

The free style-clone skill does a basic voice analysis (~10 markers). This premium skill runs a 47-marker deep analysis that captures the invisible patterns that make YOUR writing yours — the kind of patterns that fool AI detectors because they encode genuine human writing habits.

The 47 Markers

Rhythm Markers (12)

  1. Average sentence length (words)
  2. Sentence length variance (burstiness)
  3. Short sentence frequency (1-5 words)
  4. Medium sentence frequency (6-15 words)
  5. Long sentence frequency (16-25 words)
  6. Very long sentence frequency (26+)
  7. Paragraph average length (sentences)
  8. Paragraph length variance
  9. Scene-opening sentence length pattern
  10. Chapter-opening sentence length pattern
  11. Dialogue line average length
  12. Action beat average length

Vocabulary Markers (10)

  1. Vocabulary richness (unique/total word ratio)
  2. Perplexity score (word unpredictability)
  3. Top 20 signature words (words you overuse — in a good way)
  4. Top 10 avoided words (words you never use)
  5. Formality level (casual ↔ academic)
  6. Jargon/domain-specific vocabulary
  7. Curse word frequency and type
  8. Sensory word distribution (sight/sound/touch/smell/taste)
  9. Emotional vocabulary range
  10. Abstract vs. concrete word ratio

Structural Markers (8)

  1. Narrative distance (close/medium/distant POV)
  2. Scene-to-sequel ratio
  3. Dialogue-to-narrative ratio
  4. Description density per scene
  5. Flashback/memory frequency
  6. Transition style (hard cuts vs. smooth)
  7. Chapter hook style (question, action, dialogue, mystery)
  8. White space usage (single-line paragraphs as emphasis)

Dialogue Markers (7)

  1. Tag preference (said/asked vs. creative tags)
  2. Action beat vs. tag ratio
  3. Average dialogue line length
  4. Subtext level (direct ↔ heavily implied)
  5. Interruption frequency
  6. Character voice differentiation score
  7. Monologue vs. rapid exchange ratio

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.
