From the source SKILL.md

Every locale writes numbers and dates differently, and the differences are not cosmetic: 1,000 means one thousand in one place and one in another, and 03/04 is two different days depending on where you are. The rule is to never format by hand.

What this skill does

Locale Formatting is a community-contributed Claude Code skill in the linters-formatters sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/locale-formatting/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when displaying any value whose written form differs between regions.
