Runs npx -y brand-voice on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Brand Voice repository's README, as published. We do not edit it. Read it on GitHub

brand-voice

Brand writing enforcement for Claude Code — automatic, configurable, zero-friction.

Every time Claude writes or edits a Markdown file, brand-voice checks it against your brand guidelines and signals Claude to fix violations before the file saves. No manual review. No rule reminders in every prompt.

Claude reads the violation list, corrects the file, and retries the write — automatically.

Why brand-voice?

Your brand guidelines live in a doc somewhere. Claude doesn't read them unless you paste them into every prompt. Even then, the rules drift over time.

brand-voice makes the rules structural:

  • Works for any company — configure your own vocabulary, voice, and visual identity
  • Auto-corrects, doesn't just report — the PostToolUse hook blocks bad writes and triggers a retry
  • Covers the full stack — hook for Claude Code, MCP server for on-demand checks, CLI for CI pipelines
  • Smart about code — ignores fenced blocks, indented code, inline code spans, and table cells
  • Escape hatches — .brand-voice-ignore for whole files, <!-- brand-voice-disable-line --> for individual lines
  • Visual identity included — colors, fonts, logo URLs live in the same guidelines file

Install

npm install -g brand-voice

Or run without installing:

npx brand-voice@latest check

Requires Node.js 18+.

Quick Start

Option A — Guided setup in Claude Code (recommended)

Run the setup skill inside any Claude Code session:

/brand-voice-setup

The skill does everything:

  1. Asks whether you have existing brand docs or want to answer four questions
  2. Optionally researches your brand automatically via web
  3. Writes brand-guidelines.md to your project
  4. Injects a summary block into CLAUDE.md
  5. Registers the PostToolUse hook in .claude/settings.json
  6. Registers the MCP server in .mcp.json

After setup, every .md and .mdx file Claude touches is checked automatically.

Option B — Manual setup

# 1. Install
npm install -g brand-voice

# 2. Create brand-guidelines.md in your project root (see schema below)

# 3. Register the hook
brand-voice setup

How It Works

Three components work together:

What gets checked

Code blocks, inline code, indented blocks, and table rows are never checked — only prose.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
