# Prompt Engineering Review Review a prompt or instruction file against Anthropic's prompt engineering best practices and provide structured, actionable feedback. ## Arguments `$ARGUMENTS` is the path to the file to review. If not provided, ask the user which file to review. ## Procedure ### Step 1: Fetch Current Best Practices Fetch the latest Anthropic prompt engineering guidance to ground your review in current recommendations: ``` WebFetch https://docs.anthropic.com/en/docs/build-with-claude/prompt-engineering/overview ``` Use the fetched content as your primary reference for evaluation criteria.

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill prompt-review-unsupervisedcom-deepwork --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
