I18n Key Diff is a community-contributed Claude Code skill in the translation sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/i18n-key-diff/ and loads when your prompt matches the skill's trigger.
The I18n Key Diff Claude Code skill is built for content creators, marketers, copywriters, SEO professionals, and editorial teams. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
