How to use the Brand Copy Writer agent skill (brand-copy)
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Brand Copy Writer (skill name brand-copy) is an agent skill that makes an AI agent work as a brand copywriter. You give it your product details, target audience and tone, and it returns several versions of taglines, selling points and a brand story, delivered as Markdown. This guide explains what an agent skill is, how to install this one, how to ask for what you need, and where to be careful before you publish anything.

What is an agent skill and what does brand-copy do?
An agent skill is a set of instructions, packaged as a folder with a SKILL.md file, that tells an AI agent how to handle a specific kind of task. When the skill is active, the agent follows its workflow and rules instead of its default behaviour.
The brand-copy skill is in the marketing category. It turns product and audience information into multiple versions of taglines, short and long selling points, and a website and social-media brand story. It also produces a simple tone guide that lists what to say and what to avoid.
- Collects missing details in one go before writing, such as the product, the audience problem, the main difference from alternatives, the brand tone and where the copy will run.
- Opens with a one-sentence core brand proposition and three candidate angles: functional, emotional and identity.
- Delivers 10 taglines grouped by angle, with a recommended top 3 and a one-line reason for each.
- Delivers 3 to 5 selling points, each with a short and a long version.
- Delivers two brand story versions: about 150 words for a website and about 60 words for social media.
- Warns you before any efficacy, safety or financial-return claims.
How do you install the brand-copy skill?
Download the brand-copy ZIP from this page, then choose one of the two methods below. The skill itself is a single file, SKILL.md, so the folder you unzip should contain that file.
For a personal setup, unzip the skill into ~/.claude/skills/. To use it only inside one project, unzip it into the project's .claude/skills/ folder. Alternatively, if you use the Claude apps, upload the ZIP under Settings → Capabilities → Skills.
- Personal: unzip into ~/.claude/skills/ so it is available across your projects.
- Project only: unzip into .claude/skills/ inside the project folder.
- Claude apps: upload the ZIP under Settings → Capabilities → Skills.
How do you trigger the skill with a natural request?
You do not need a special command. Describe the product, the audience and what you need, and ask for the copy in plain language. The skill's own quick prompts are a good model for the kind of request it expects.
If your request is missing details, the agent should ask for them in one go before writing. You can also give everything up front to skip that round.
- Write 10 taglines for this product and recommend the top 3.
- Rewrite these feature points as user-centred selling points.
- Write a brand story for our homepage, about 150 words, for small business owners who lose time to manual invoicing.
- Give me a tone guide for a warm, professional brand aimed at first-time home buyers.
What should you give the agent before it writes?
The more specific your input, the more usable the output. The skill asks for these items, and you can include them in your first message.
If you already have a tagline or visual language, mention it. The skill is designed to build on existing material rather than start over. You can also name banned words.
- What the product is.
- Whose problem it solves and which problem.
- The biggest difference from alternatives.
- The brand tone, such as professional, warm or sharp.
- Where the copy will run: homepage, packaging or paid ads.
- Any banned words or existing taglines.
How do you read and use the output?
The reply is a Markdown document titled with your product name followed by Brand Copy. Taglines and selling points are numbered so you can copy them directly. After delivery, the agent suggests where each version is best placed and asks which group you want to develop further.
Treat the output as a set of drafts. Each selling point's long version is meant to contain one verifiable fact, and any fact you did not supply is marked TBD so you can fill it in.
- Pick the angle closest to your product, or say "you decide" and the agent will choose the one nearest your point of difference.
- Check every fact against your own records.
- Replace any TBD with a real specification, scenario or comparison.
- Ask for a language version after the main copy is final; the skill says taglines are not translated word for word.
What are the safety notes and limits?
The skill requires nothing to be installed beyond the skill files. It does not run scripts and does not use the network, according to its listing. It also cannot verify facts about your product.
The skill's own rules say claims about efficacy, safety or financial returns get an advertising-law compliance warning first and need legal review before they run. Regulated categories such as health, finance and food carry real risk if claims are wrong. The skill is also built not to add awards or user counts, but you should still check every fact it uses.
- Runs scripts: no.
- Uses network: no.
- Requires: nothing listed.
- Always get legal review for efficacy, safety or return claims before publishing.
What people use it for
- Generating a batch of tagline options for a small team's new product launch.
- Drafting homepage selling points that a marketer can edit before publishing.
- Writing a 150-word website brand story and a 60-word social post from the same brief.
- Creating a tone guide with clear do-say and never-say pairs for a writing team.
- Rewriting technical feature lists as user-centred selling points.
Frequently asked questions
Is the brand-copy skill free to use?
The skill is published under the Apache-2.0 licence, as shown on this page. Check the licence text in the repository for the terms that apply to your use.
What do I need to install brand-copy?
The listing says it requires nothing beyond the skill itself. It runs no scripts and uses no network, and you install it by unzipping the ZIP into a skills folder or uploading it in the Claude apps.
Where do I put the brand-copy skill folder?
For personal use, unzip it into ~/.claude/skills/. For a single project, unzip it into that project's .claude/skills/ folder. In the Claude apps, upload the ZIP under Settings → Capabilities → Skills.
Can the skill write copy in other languages?
Yes, with a specific order. The skill finalises the copy in your language first, then creates the other-language versions, and it does not translate taglines word for word.
Can brand-copy check whether my product claims are true?
No. The skill cannot verify facts about your product. It warns you before efficacy, safety or financial-return claims and says legal review is needed, so you must check facts yourself.
How does brand-copy compare with writing copy by hand or with a general AI prompt?
The skill gives a fixed structure: a core proposition, three angles, 10 taglines, selling points with short and long versions, two brand story lengths and a tone guide. A general prompt can produce similar text, but this skill's workflow and rules keep the output consistent. The listing does not compare it with named alternatives.

Our verdict
Use brand-copy if you are a small team, founder, marketer or writer who needs a quick batch of structured marketing drafts to edit. Pick something else, or bring in a professional, if your copy makes health, finance or food claims or must be final without review, because the skill cannot verify facts and says legal review is required for those claims.
