Lighthouse for Claude Code artifacts
Prove your skill is good
before you ship it.
Beacon audits a Claude Code skill — structure, triggering, token cost, and safety — and returns an evidence-cited scorecard with a letter grade. File-and-line receipts. No vibes.
Scan any public repo, or run it locally: npx @sgharlow/beacon ./my-skill
Shareable scorecard
Every scan is a public URL you can send — a Lighthouse-style grade dial, category bars, and ranked fixes.
Embeddable badge
Drop an always-fresh Beacon: A− badge in your README. It updates every time you re-scan.
Catches the real failures
“My skill never triggers,” a hardcoded key, an over-broad tool grant, token bloat — before anyone else sees it.
