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.
