Path Rules

Translation Guidelines

Preserve (Do NOT translate)

• Code blocks and inline code
• Technical terms: API, JSON, REST, HTTP, OAuth, JWT, SDK, CLI, etc.
• Product/service names: Firebase, Vercel, GitHub, etc.
• URLs and file paths
• Frontmatter fields: slug, sidebar, draft, editUrl

Translate

• Frontmatter: title, description
• Prose paragraphs
• Comments explaining code (translate the explanation, not the code)
• Alt text for images

Style for Global Engineers

English output:

• Use simple, direct sentences
• Prefer active voice
• Avoid idioms and cultural references
• Use standard technical terminology

Japanese output:

• Use です/ます form
• Keep sentences concise
• Preserve English technical terms in katakana only when commonly used (e.g., クラウド, サーバー)
• Keep original English for terms engineers use as-is (e.g., API, JSON, Firebase)
