What you get for $39

Claude Skill registration

$39

one-time · USD · no subscription

Permanent PDF certificate with QR code
Embedded in the certificate and downloadable as a 1024×1024 PNG. Drop it in your GitHub README, docs, or LinkedIn — one scan and anyone can verify authorship.
Semantic near-duplicate protection
After payment we run a similarity check against the existing Claude Agent Skills Registry. If a later submission is strongly similar to yours, you receive an email with the new registrant's name and contact.
SHA-256 fingerprint + UTC timestamp
Cryptographic proof that this exact .mdc or SKILL.md file existed at this exact moment, anchored to your declared name.
Exact duplicate check before payment
Byte-identical matches are surfaced as a warning on this page before checkout. You see the prior registration and can decide to proceed anyway.
Permanent public verification URL
Every registration gets a fixed /v/<reg> link that resolves forever — no accounts, no API keys, no SkillAuthor login required to verify.

No accounts, no subscriptions, no recurring fees. Permanent record on the Claude Agent Skills Registry.
