What this skill tells the agent
Voice & Tone Analysis
Purpose
Extract and document a writer's distinctive voice patterns for consistent reproduction. Creates a "voice guide" that enables authentic writing that sounds like the source, not a generic approximation.
Core Principle
Capture spirit, not just mechanics. The goal is writing that makes the source say "yes, that's me" not "I guess that's accurate."
Phase 1: Sample Collection
Gather 5-10 Examples from Each Category
Peak Voice - Writing they identify as "most them"
Off-Voice - Writing that doesn't represent them well
Different Contexts:
- Technical/instructional content
- Persuasive/argumentative pieces
- Narrative/storytelling
- Casual communication (emails, messages)
- Formal communication
- Emotional/vulnerable content
Self-Report Prompts
Rewrite Exercise: Ask: "Rewrite this neutral paragraph in your voice:"
"The new policy will be implemented next month. It includes several changes to current procedures. Employees should review documentation and submit questions by the deadline."
Rule Breaking: "What writing 'rules' do you consistently ignore? Why?"
Pet Peeves: "What writing choices immediately signal something wasn't written by you?"
Evolution: "How has your writing changed in 5 years? What stayed constant?"
Phase 2: Linguistic Analysis
Sentence Level
| Pattern | What to Track |
|---|---|
| Average length | Words per sentence |
| Range | Shortest to longest |
| Fragments | Usage frequency, contexts |
| Run-ons | Tendency, intentionality |
| Opening patterns | How sentences typically start |
| Closing patterns | How sentences typically end |
Paragraph Architecture
| Element | What to Track |
|---|---|
| Average length | Sentences per paragraph |
| Topic sentences | Beginning, middle, end, absent |
| Transitions | Explicit words, implicit flow, abrupt |
| Information order | Build-up, front-load, circular |
Punctuation Signature
| Mark | Track Usage Pattern |
|---|---|
| Em dash | Interruption, emphasis, list, asides |
| Parentheses | Frequency, content type |
| Semicolon | Presence, absence, alternative |
| Ellipsis | Trailing, pause, omission |
| Exclamation | Frequency, contexts |
| Rhetorical questions | Frequency, function |
Phase 3: Lexical Fingerprinting
Word Choice Matrix
| Category | Preferred | Avoided | Signature Examples |
|---|---|---|---|
| Technical terms | |||
| Colloquialisms | |||
| Intensifiers | very, extremely, quite... | ||
| Hedging | perhaps, might, seems... | ||
| Abstract/concrete |
Register Analysis
- [ ] Consistent register (formal/informal throughout)
- [ ] Deliberate register mixing (formal content, casual asides)
- [ ] Context-dependent shifting (formal for X, casual for Y)
Recurring Constructions
List phrases/patterns appearing 3+ times:
- ___
- ___
- ___
Phase 4: Conceptual DNA
Metaphor Mapping
| Source Domain | Target Domain | Example | Frequency |
|---|---|---|---|
| (war, journey, building...) | (ideas, processes...) |
Reference Pool
- Cultural touchstones: (movies, books, memes, history...)
- Time period: (contemporary, 90s, classic...)
- Accessibility level: (mainstream, niche, insider)
- Domains drawn from: (sports, cooking, science...)
Reasoning Patterns
Rate 1-5 for prevalence:
- [ ] Analogical reasoning (like X, therefore Y)
- [ ] First principles (from basics up)
- [ ] Empirical evidence (data, studies)
- [ ] Personal anecdote (I experienced...)
- [ ] Hypotheticals (imagine if...)
- [ ] Socratic questioning (but what if...?)
Phase 5: Emotional Texture
Enthusiasm Spectrum
| Low | Medium | High |
|---|---|---|
| (understated) | (balanced) | (expressive) |
Criticism Styles
| Style | When Used | Markers |
|---|---|---|
| Direct | "This is wrong because..." | |
| Diplomatic | "One consideration might be..." | |
| Humorous | "Well, that's one way to..." | |
| Analytical | "The issue breaks down to..." |
Vulnerability Patterns
- Admission phrases: "I'll admit...", "honestly..."
- Uncertainty markers: "I think...", "not sure but..."
- Personal revelation style: Direct? Buried in humor? Rare?
Phase 6: Reader Dynamics
Positioning
The writer positions as:
- [ ] Expert/teacher (I know, let me explain)
- [ ] Peer/collaborator (we're figuring this out together)
- [ ] Student/learner (I'm working through this)
- [ ] Challenger/provocateur (conventional wisdom is wrong)
- [ ] Guide/facilitator (here's how to navigate)
Assumed Context
- Shared knowledge level: Assumes expertise? Explains basics?
- Cultural assumptions: In-group references? Universal?
- Relationship warmth: Distant professional? Familiar?
Interactive Patterns
- Questions per 1000 words: ___
- Direct address frequency ("you"): ___
- Imperative usage (commands): ___
- Inclusive language ("we/us"): ___

The Litmus Test
A piece captures this voice when: 1. 2. 3.
Red Flags
Definitely NOT this voice when: 1. 2. 3.
Phase 8: Validation
Before finalizing the voice guide:
- [ ] Can identify the author in a blind test?
- [ ] Guided writing feels authentic, not performative?
- [ ] Patterns are descriptive, not prescriptive?
- [ ] Captures spirit, not just mechanics?
- [ ] Source would say "yes, that's me"?

The Heart of the Voice
_[Single paragraph essence]_
Emergency Voice Recovery
When writing has gone generic, add: 1. 2. 3.
Usage Notes
For AI Writing
Once the voice guide is complete, include relevant sections in the prompt to guide generation toward authentic voice reproduction.
For Self-Analysis
Writers can use this framework to understand their own voice, identify what makes their writing distinctive, and consciously apply those patterns.
For Editing
Use the voice guide as a checklist when editing to ensure consistency and authenticity.
Anti-Patterns
1. Mechanics Over Spirit
Pattern: Cataloging every linguistic feature without understanding what makes the voice feel distinctive. Why it fails: A perfect inventory of word frequencies and sentence lengths can produce writing that's technically accurate but feels like a parody. Voice is gestalt, not components. Fix: Start from "what makes this voice feel like this?" Work backward to mechanics. The inventory serves understanding; understanding doesn't emerge from inventory alone.
2. Single-Context Capture
Pattern: Analyzing voice from one type of writing, then applying it to all contexts. Why it fails: Writers shift voice across contexts. Technical writing voice differs from casual email voice. Capturing one context and forcing it everywhere creates uncanny artifacts. Fix: Sample across contexts. Map how voice shifts. Include context-switching rules in the voice guide. Understand which elements are constant vs. context-dependent.
3. Frequency as Rule
