How does it check the latest version of the specification?

The skill automatically discovers the latest spec version by fetching the official build site from the C2PA organization's repository, ensuring your implementation is checked against current standards.

Does this skill support specific C2PA versions?

Yes, you can optionally provide a target version (e.g., 2.1) and the skill will fetch the corresponding specification documents for that specific release.

What is the C2PA Spec Compliance skill?

It is a specialized capability for Claude Code that reviews code and designs to ensure they meet the Coalition for Content Provenance and Authenticity (C2PA) technical standards.

What specific components does this skill audit?

It checks manifest structures, JUMBF boxes, claim fields, assertions, signature algorithms, hash binding, and trust validation/certificate chains.

When should I use this skill?

It is best used during the planning phase to validate designs, during code reviews to verify implementations, or during testing to troubleshoot compliance errors.

Seguridad y Pruebas

Verifies software and code implementations against the official C2PA (Coalition for Content Provenance and Authenticity) specifications for content provenance.

Acerca de

The C2PA Spec Compliance skill provides developers with an automated way to audit their implementations against the complex requirements of the Coalition for Content Provenance and Authenticity standard. By dynamically fetching official specifications from the C2PA repository, this skill can analyze code, designs, and manifests to ensure compliance with JUMBF structures, claim generation, signature algorithms, and hash binding. It provides a structured report with specific citations from the spec, making it an essential tool for developers building trustworthy digital content systems that require verifiable origin and edit history.
