# Content guidelines

Encodes the MetaMask Content Design Style Guide for AI-assisted development.
Covers capitalization, punctuation, voice and tone, and the approved
terminology list. For component-specific copy rules, refer to the relevant
component README in MetaMask/metamask-design-system (exposed via Storybook MCP).

## When to use

- Writing or reviewing user-facing product strings in locale files (`locales/**/*.json`)
- Checking the same content standards in component stories, constants, and README examples
- Auditing terminology (gas fee → network fee, dapp → site, etc.)
- Reviewing sentence case, punctuation, voice, or tone in any user-facing string

## Out of scope

- Component-specific copy patterns — these live in each MMDS component README
- Code style, TypeScript conventions, or component API decisions (see `ui-development`)
- Marketing or external comms copy
