Brand skill brief prompt: free ChatGPT template
Updated · By Robert Breen
Use this when proposals, flyers and social posts keep coming out looking different, because you explain your brand to Claude from scratch each time. It turns your brand rules into one brief that Claude can save as a skill and apply whenever a request matches.
Give every color a job, name a fallback font for each brand font, and attach your logo to the chat. It does not design a brand for you. If you do not have colors and fonts yet, decide them first.
The prompt
Copy it into ChatGPT (or Claude, Gemini or Copilot) and replace every [BLANK] with your own details. It uses the four parts from Prompt Writing 101: Role, Context, Task and Format.
Role: You are a brand designer at [BUSINESS], using Claude's skill creator to write our brand rules as a skill. Context: Our colors, each with its job: [COLORS]. Our fonts: [FONTS], each with a fallback font. Logo rules: [LOGO RULES]. Our voice: [VOICE]. Use only these rules. Do not invent colors, fonts or slogans, and ask me if something is missing. Task: Draft a brand skill with a description that says to use it for anything a customer will see. Include sections for colors, fonts, logo and voice, and add the sign-off we use: [SIGN OFF]. Then show me the draft before saving it. Format: The skill as a SKILL.md with a short description first, then four short sections, one per rule type. Plain words, under [WORD LIMIT] words.
Fill in the blanks
[BUSINESS]- Your business name.
[COLORS]- Each color with its hex code and what it is used for.
[FONTS]- Heading and body fonts, plus a fallback for each.
[LOGO RULES]- Where the logo goes on documents and slides, and what never to do to it.
[VOICE]- Three to five short rules for how you sound.
[SIGN OFF]- The closing line you use.
[WORD LIMIT]- 400 keeps the skill short and easy to read.
Example, filled in
A made-up example from the free lesson Make Every Claude Document On-Brand with a Brand Guidelines Skill. Fernbrook Florals is the made-up flower shop in the Brand Guidelines Skill lesson. The brand details below are an illustration of how the shop might fill the prompt in, not the lesson's exact data.
Role: You are a brand designer at Fernbrook Florals, using Claude's skill creator to write our brand rules as a skill. Context: Our colors, each with its job: fern green for headings and the logo, blush for accents, cream for backgrounds, charcoal for text. Our fonts: Playfair Display for headings and Lato for body text, each with a fallback font. Logo rules: top left on documents, bottom right on slides and social posts, never stretched or recolored. Our voice: warm, plain and confident, short sentences, at most one exclamation mark. Use only these rules. Do not invent colors, fonts or slogans, and ask me if something is missing. Task: Draft a brand skill with a description that says to use it for anything a customer will see. Include sections for colors, fonts, logo and voice, and add the sign-off we use: Fresh from our shop to your door. Then show me the draft before saving it. Format: The skill as a SKILL.md with a short description first, then four short sections, one per rule type. Plain words, under 400 words.
What a good answer looks like
- Every color has a job, so Claude knows where to use it and not only what it looks like.
- Each font has a fallback, which keeps Word and PowerPoint files readable on computers without your fonts.
- You review the draft before it is saved, so you catch a wrong rule early.
How to check it before you use it
An AI draft can sound right and still say something you never told it. Use the habit from the Reply Faster lesson: check every promise, name, date and number against what you gave it before anything goes out.
- Compare the hex codes in the draft with your real brand guide, character by character.
- Ask for a proposal and a social post and look at both next to your logo before you rely on the skill.
- Check that the logo actually made it into the skill's files and was not left in the chat.
- Do not upload anything that is not yours to share, such as a client's logo.
Why this prompt works
Brand rules are a classic skill because they apply to many different documents but never change. Writing the rules once means the proposal, the price sheet and the Instagram post all follow them, with no repeated explaining.
Practice it in the free lesson
Make Every Claude Document On-Brand with a Brand Guidelines Skill: Build a brand skill for a small flower shop by chatting with Claude: colors, fonts, logo placement and voice. Then ask for a proposal and a social post and watch both come out on brand. You do every step yourself in a practice copy of Claude, and nothing touches your real accounts.

Frequently asked questions
- Will the skill make Claude use my fonts?
- Only as far as the file allows. Word and PowerPoint show a font only on computers that have it installed, which is why each font needs a fallback.
- Should I use Anthropic's brand-guidelines skill?
- Use it as a pattern only. Its colors and fonts are Anthropic's own, so switching it on would make your documents look like theirs.
