Verify Content Credentials

Use the official verifier and preserve uncertainty. A valid signature is not automatically a trusted signer.

All paths below are relative to this skill's directory. If you are running from elsewhere, use an absolute path to scripts/verify_c2pa.py.

Workflow

  1. Preserve the source asset.

  2. Confirm c2patool -V works, or pass its explicit path with --c2patool. The wrapper requires c2patool 0.20.0 or newer and reports verifier_supported: false with an actionable reason on older builds rather than degrading silently.

  3. Run base integrity verification:

    python3 scripts/verify_c2pa.py /absolute/path/to/asset
