# Set content rules for your agents

> Write the rules every agent follows when it writes content on your site, from voice and images to who approves, and see the terms already in use.

Content rules are short written guidance for anyone who writes content on your site: Willo in chat, the Growth Engine, Agent Programs and outside AI agents connected with a token. Every one of them reads the rules before it writes or edits a post.

## Write your rules

1. Open your business and go to **Content**.
2. Select **Rules** in the toolbar. A panel opens on the right.
3. Pick **Site-wide** for rules that cover everything, or a collection (Blog, Testimonials, …) for rules that only apply there. A collection's rules apply on top of the site-wide ones.
4. Fill in the boxes that matter to you, in your own words, then select **Save rules**. Leave the rest empty.

The boxes are:

- **Voice**: how your content should sound.
- **Words to avoid**: words, phrases or topics agents should never use.
- **Images**: when to use images and how to describe them.
- **Who approves**: who decides before something goes live, for example "agents write drafts only, I publish".
- **How often to post**: how often, and on which days.
- **Anything else**: any other guidance, such as post length or a closing question for the reader.

Each section holds up to 8,000 characters in total. Editors, admins and owners can change rules. Viewers can read them. Short, concrete sentences work best.

## Terms already in use

Under a collection's rules, the panel lists the categories and tags that collection's items already use, most used first. Agents see the same list with the rules and reuse those terms before adding new ones, so `Tips & Tricks` doesn't turn into `Tips and Tricks`. The list updates as items change; there is nothing to maintain.

## Have Willo draft them

Ask Willo in chat: "Draft content rules for my site." Willo reads your brand guide and your existing categories and tags, writes a proposal, and shows it to you on a card with the old and new text. Nothing changes until you approve the card. You can edit the result in the Rules panel at any time.

## Versions and changes

Each section shows its version and when it was last saved. If two people edit the same section at once, the second save is refused and your changes stay in the boxes so you can check them and save again.

When Willo or a connected agent changes the rules, you approve it first on a card that shows the change. Growth Engine runs and Agent Programs read the rules but never change them.

## What rules don't do

Rules guide agents; they don't block anything. A post that breaks a rule can still be saved and published, and publishing follows the same permissions as always. See [Who publishes content](https://www.willo.ai/docs/content/who-publishes).

To remove a section, clear its text and select **Remove rules**.
