This is Anthropic's official Skill for generating brand guideline documents, maintained in their public skills repository. It's a pure prompt template that structures Claude's output into usable brand books covering voice, tone, colour, typography, and usage rules. Because it's a Skill rather than an MCP server, it runs entirely within Claude's context window with no external code execution, network calls, or filesystem access. The supply chain is as simple as it gets: a YAML file in Anthropic's GitHub repo that Claude Desktop reads directly. No dependencies, no install scripts, no package managers. The only theoretical risk is if someone compromised Anthropic's GitHub account, but that would affect their entire product line. For a writing template that touches no systems and executes no code, this is about as safe as software gets. The editorial review confirms it produces actionable output rather than vague guidance.

Brand Guidelines is an Anthropic Skill that gives Claude a structured template for drafting comprehensive brand guideline documents. It covers voice and tone (with specific examples, not vague adjectives), colour palettes (hex codes and usage rules), typography (font pairings and hierarchy), and do's and don'ts sections that prevent common brand misuse. The output is formatted for immediate use in Notion, Google Slides, or PDF exports. It's designed for startups building their first brand book, content teams standardising voice, or agencies drafting client-facing decks. You'll still need to provide context (existing assets, target audience, competitive positioning), but the Skill ensures nothing gets missed. It's a starting point, not a finished artefact, but it's a much better starting point than asking Claude to wing it.

Review

I've asked Claude to draft brand guidelines before, and the results were always a bit scattershot: some colour hex codes here, a vague paragraph on tone there, nothing you could actually hand to a designer or copywriter. This Skill fixes that. It gives Claude a structured template for brand books that covers voice, tone, colour palettes, typography, and the crucial do's and don'ts section that stops people from winging it. I tested it on a fictional SaaS startup and got a usable first draft in about two minutes. The voice section was specific enough to be actionable (it suggested sentence structures, not just adjectives like "friendly" or "professional"). The colour palette came with hex codes and usage guidance. Typography recommendations included font pairings and hierarchy rules. The do's and don'ts were genuinely helpful, not just "be consistent" platitudes. What it does well: it forces completeness. Without the Skill, I'd forget to cover accessibility or logo misuse. With it, Claude walks through every section methodically. The output format is clean enough to drop into a Notion doc or Google Slides deck without much editing. Rough edges: it's still a starting point, not a finished artefact. If you're working with an established brand, you'll need to feed Claude existing assets and context. The Skill doesn't magically know your Pantone codes or your existing voice guidelines. It's also overkill for tiny projects. If you're just writing a few blog posts, you don't need a 12-page brand book. I'd reach for this when I'm working with a startup that's never formalised its brand, or when a content team needs a shared reference doc and no one has time to write it from scratch. It's not a replacement for a brand designer, but it's a solid brief for one.

Verdict

Load this if you're drafting a brand book from scratch or standardising voice across a team. Overkill if you just need a quick tone guide for a single project.

Good at

Structured template ensures completeness (voice, tone, colour, type, usage rules)
Output is clean and ready to drop into Notion, Slides, or PDF
Specific examples in voice section, not just adjectives
Includes accessibility and logo misuse guidance by default
Saves hours compared to drafting from scratch

Watch out

Still requires context and existing assets for established brands
Output is a starting point, not a finished brand book
Overkill for small projects or single-use tone guides
No visual design output (you'll still need a designer for layouts)
Assumes you can articulate your brand positioning clearly

Use cases

Producing a v1 brand book for a startup
Standardising voice across a content team
Drafting client-facing brand decks
Auditing existing collateral against a guideline set
