Paste a Claude Agent Skill's SKILL.md below. We lint it and run a static

Sign in to scan — free, 5 scans/day, syncs across your devices. Or upgrade to Pro (100/day for $5).
One account, any device: sign up above to get an API key, use it from your phone and your laptop, and the same 5/day free quota (or Pro allowance) is shared — no double-paying because you switched devices. Batch-scan up to 25 files per call once Pro is active. Pay in USDC on Solana, no card, no subscription-billing surprise (Pro just expires after 30 days). Full API docs: GitHub.
