What goes into a brand voice guide?
Most voice guides say "friendly but professional" and stop there, which gives a writer, or an AI, nothing to work with. This skill reads a handful of pages you think sound like you and picks out what they actually do: how long the sentences run, how formal they get, the words you reach for and the ones you'd never use.
It turns that into a guide with plain rules, each backed by a line from your own pages, plus before-and-after examples. On a MetaMonster plan, Claude can save the guide to your site's Context Library, and every title, brief and draft MetaMonster writes for the site follows it.
MetaMonster tools it uses
Works without a MetaMonster plan
- Context Library guidance What the skill uses it for: Reads the site's current brand voice and saves the new guide so MetaMonster's content follows it Without a plan? Plan needed
- Context search What the skill uses it for: Finds how customers describe things in the call transcripts you've added Without a plan? Plan needed
Without a plan, the skill reads your pages itself and writes the guide for you to keep.

# Brand voice
You write a voice guide from what the user's own pages do, not from adjectives. Every rule must point to a line from their pages.
## 1. Get the pages
Ask for 3 to 5 URLs that sound the way the user wants, and optionally 1 or 2 that don't. Ask who the audience is.
## 2. Read them
Fetch and read each page. Note sentence length, how formal it is, whether it uses "you" and "we", how much jargon there is, humor, formatting habits such as headings, lists and sentence case, and words that come up again and again. Copy out short lines that show each habit.
## 3. Add what MetaMonster knows, on a plan
If the user has a MetaMonster plan and the site is in MetaMonster, call `get_site_guidance` to read the current brand voice. If they've added call transcripts, call `search_context` (for example, with "how customers describe the problem") to find the words customers use. Never present customer words as the brand's own claims.
## 4. Write the guide
- A short paragraph that sums up the voice.
- 5 to 8 rules. For each one, give a line from their pages that shows it, and a short do and don't.
- Words and phrases to use, and ones to avoid.
- Formatting habits.
- 2 before-and-after rewrites of a generic sentence in their voice.
Don't invent quotes, customers or claims.
## 5. Save it, if they ask
On a MetaMonster plan, offer to save the guide as the site's brand voice with `update_site_guidance` (`voice_tone`). This replaces the current brand voice, so show the user the current one first and save only when they say so.
