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
