The Voice Fingerprint
Extract a reusable voice profile from your best writing
$ npx skills add sidchaudhary/gtm-skills/skills/brand-designer/the-voice-fingerprintWhat it does
Analyzes your content samples to extract a reusable voice profile - 6 dimensions, vocabulary rules.
You'll know it's time when...
Writers are sounding different from each other, and the voice guide is either missing or being ignored.
How it works
Run it in three steps
Install
Copy the install command above and run it in your project.
Ask Claude
Ask for what you need in plain English, no prompt tuning required.
Get the output
Claude returns a structured artifact aligned to your ICP and voice.
Context
- Check for
.agents/product-context.md. If missing, ask the user to run/gtm:product-contextfirst. If the user prefers to proceed without it, ask for the minimum required info inline: brand voice summary, ICP, and primary color. - Read
.agents/product-context.mdfor any existing brand voice notes.
Inputs
- Ask: "Paste 3-5 examples of your best content, the pieces that sound most like you." If fewer than 3 samples are provided, proceed but note that confidence in ratings is lower.
Process
- Read
references/brand-voice-dimensions.mdfor the 6 voice dimensions and their rating scales. - Analyze all content samples across the 6 voice dimensions:
- Formality (1 = casual, 10 = formal)
- Energy (1 = calm, 10 = high-energy)
- Humor (1 = serious, 10 = playful)
- Authority (1 = peer-level, 10 = expert)
- Warmth (1 = detached, 10 = personal)
- Complexity (1 = simple, 10 = technical)
- Rate each dimension 1-10 with a descriptive label (for example, a 7 paired with the label "Confident expert"). Keep the rating number and the label as separate values, never joined into one string with a dash.
- Identify vocabulary patterns: frequently used words, characteristic phrases, power words.
- Identify banned words or patterns: terms the brand avoids, cliches absent from samples.
- Determine jargon policy: does the brand use industry jargon freely, sparingly, or never?
- Analyze sentence structure: average sentence length, active vs. passive voice ratio, question frequency, use of fragments.
- Generate do/don't examples for each dimension: show a "sounds like us" and "doesn't sound like us" pair.
- Generate channel-specific adaptations: how the voice shifts for website copy, social media, email, and documentation.
Output
- Format the brand voice profile as:
Voice Profile
| Dimension | Rating /10 | Description |
|---|---|---|
| Formality | X | [label] |
| Energy | X | [label] |
| Humor | X | [label] |
| Authority | X | [label] |
| Warmth | X | [label] |
| Complexity | X | [label] |
Vocabulary
- Preferred words: [list]
- Banned words: [list]
- Jargon policy: [free / sparingly / never]
Sentence Patterns
- Average length: X words
- Active voice: X%
- Question frequency: [per paragraph or section]
- Fragment usage: [yes/no, when]
Do / Don't
| Dimension | Do (sounds like us) | Don't (doesn't sound like us) |
|---|
Channel Adaptations
| Channel | Voice Modifier | Example |
|---|---|---|
| Website | [adjustment] | [sample sentence] |
| Social | [adjustment] | [sample sentence] |
| [adjustment] | [sample sentence] | |
| Docs | [adjustment] | [sample sentence] |
Quality check before returning
- Before returning the output, verify:
- Is every dimension in the Voice Profile table rated 1-10 with a descriptive label, not just a bare number?
- If fewer than 3 samples were provided, is the lower-confidence note actually present in the output?
- Does the Do/Don't table have at least one real pair per dimension, drawn from the samples, not invented examples?
- Do the Channel Adaptations reference an actual pattern found in the samples rather than a generic statement that could apply to any brand?
If any check fails, correct it before returning the output.
- End every output with:
