chainctl skills verify

Verify that Chainguard signed a published skill.

Synopsis

Verify that Chainguard’s publishing pipeline signed a published skill for the organization that owns it.

The reference accepts org/name:tag or org/name@sha256:DIGEST. A tag is resolved once and the digest is verified; the output prints that digest so you can pin it.

Verification passes only when a sigstore bundle attached to the digest chains to the public-good Sigstore trusted root, was issued by https://issuer.enforce.dev to exactly the owning organization’s SKILLS service principal, and has a verified transparency-log entry and timestamp. The signing identity of Chainguard’s own organizations (public, chainguard) is built into chainctl; for any other organization, chainctl reads its SKILLS binding with your credentials, which requires the viewer role (or higher) on that organization.

The result is one of: verified, unsigned, failed, or skipped. Skills on a staging or development registry are skipped with a warning; uploads are never Chainguard-signed and always fail. The command exits 0 for verified and skipped, and 1 for unsigned and failed (the status field tells them apart); an error that stops verification from running also exits nonzero.
