Install it in Claude as an Agent Skill, or copy it into ChatGPT, Gemini, or any assistant. Same method either way.
What this does and why it matters
When every writer and every tool sounds different, a brand feels untrustworthy and forgettable. This skill builds a practical, example-driven voice guide that anyone (or any AI) can apply to produce content that sounds unmistakably like the brand, which is what makes content compound into recognition.
Inputs to gather
- Examples of content that sounds right, and content that sounds wrong.
- The audience and how the brand wants to make them feel.
- The brand's personality and point of view.
- Any hard rules (words banned, formatting conventions, claims to avoid).
Method
1. Define the voice in traits, then show them
Name three to five voice traits (for example: direct, warm, expert, plain-spoken). Traits alone are useless, so pair each with a "this not that" example that makes the trait operational.
2. Capture the personality and point of view
What the brand believes, the stance it takes, and the register (formal to casual). A brand with a point of view is memorable; a neutral one is wallpaper.
3. Set concrete rules
Sentence length tendencies, person (we, you), how to handle jargon, humor, and emotion. Include a banned and preferred word list, since specific word choices carry more brand signal than abstract adjectives.
4. Document formatting conventions
Headings, capitalization, numbers, dates, and any signature stylistic rules, so mechanics stay consistent.
5. Provide before-and-after rewrites
The single most useful part of a voice guide: take an off-brand passage and rewrite it on-brand, so the guide teaches by demonstration.
Output format
ALWAYS use:
# Brand Voice Guide: [Brand]
## Voice in one line
## Voice traits (each with "this not that" examples)
## Personality and point of view
## Register and audience feeling
## Rules (person, sentence style, jargon, humor)
## Preferred and banned words
## Formatting conventions
## Before-and-after rewrites (2 to 3)
Anti-patterns to avoid
- Abstract adjectives with no examples.
- A guide so long no one uses it.
- Rules with no demonstrations.
- Ignoring the mechanical conventions that also signal brand.
Example
For a direct, operator brand, the guide bans hedge words and corporate filler, prefers plain verbs and short sentences, and shows a before-and-after turning a fluffy paragraph into a crisp one.
