An error is a moment of friction; a good error message turns it into a recovery. The formula is simple and rarely followed: say what happened, in plain language, and what to do next — without blaming the user or exposing a stack trace. This skill writes error copy that helps people get unstuck and keeps trust intact.
Error Message Writer is a community-contributed Claude Code skill in the content-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/error-message-writer/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to write an error message, validation text, a failure/empty-error state, or to rewrite a cryptic system error. Produces human, blame-free error copy — what went wrong, why (if useful), and the next step — with options per surface (inline, toast, full page) and the related success/empty states.
The Error Message Writer 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 178,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
