## Best for

A hover gutter that adds, drags, duplicates, moves and converts blocks, plus Full Width, Small Text and Lock Page toggles

## Agent notes

- `PAGE`, `PAGE_META` and `PEOPLE` in data.ts are the demo playbook, its title and the teammates; mentions and `TIERS` owners store `PEOPLE` ids
- `createRichTextMention` gets `PEOPLE` at module scope in `EXTENSIONS`, so the @ list is fixed at load and shows at most `MAX_MATCHES`
- Full Width, Small Text and Lock Page are local state (`fullWidth`, `smallText`, `setEditable`) and reset on reload

## When not to use

- A fixed formatting toolbar over a bounded document with a live word count: use [Document Editor](https://web.dev.reui.io/blocks/application/rich-text-editor/rich-text-editor-1.md) (`get_block("rich-text-editor-1")`)
- Changes need accepting or rejecting one by one, each tagged to its author: use [Contract Redlines](https://web.dev.reui.io/blocks/application/rich-text-editor/rich-text-editor-3.md) (`get_block("rich-text-editor-3")`)

## About Rich Text Editor blocks

### When to use

- Documents written and kept inside a product: launch briefs, wiki pages, contracts, specs and plans
- Review on the text itself, through tracked suggestions to accept or reject or threaded comments
- Shared writing with live teammates, or with an AI assistant whose edits arrive for review

### When not to use

- The navigation layout around your pages, with no document editing in it: use the [App Shell blocks](https://web.dev.reui.io/blocks/application/app-shell.md)
- A top bar with a title, avatars and actions above a page you already have: use the [Navbar blocks](https://web.dev.reui.io/blocks/application/navbar.md)
- A strip of formatting or alignment controls alone, with no document under it: use [Button Group](https://web.dev.reui.io/components/button-group.md) (`get_component("button-group")`)

### Agent notes

- Each page.tsx wraps the root in an `h-svh` or `min-h-svh` column; inside an app shell drop it and size the root through `className`
- Every schema starts from `createRichTextExtensions` in rich-text-extensions.ts; extend that list and keep it stable, as `useEditor` compares it by identity
- Document typography is `RICH_TEXT_PROSE` in rich-text-content.tsx, built on theme tokens; restyle headings, lists, code and links there

Every ReUI item has a twin like this one; the index is https://web.dev.reui.io/llms.txt. Agents with the ReUI MCP (https://web.dev.reui.io/docs/mcp) get the same guidance from the getters named above.
