Chain of custody

Scanners check what the code says. This traces who ships Claude Seo and whether that has changed: from the source repository, through how changes are reviewed and released, to the code you run. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities and, for skills, AST02 Supply Chain Compromise.

Source Signed

github.com/AgriciDaniel/claude-seo, MIT, last pushed 2026-10-04. 82% of the last 100 commits carry a verified signature, so changes trace to a verified account.

Verify this score yourself

Every build re-issues Claude Seo’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.

Signed credential (JSON) How to verify

What this score doesn’t check

It covers who ships the code, not what the code does. It doesn’t read the skill’s instructions for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you install it, such as Cisco Skill Scanner.

In Agent Skills

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade B reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Common questions about Claude Seo

Claude Seo has a mixed signal profile. Some trust indicators are present, others are missing. Whether it is safe for your use case depends on which gaps matter to you — review the breakdown below before adopting in production.

Does Claude Seo publish package provenance?

No published build provenance is currently detected for Claude Seo. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.

Does Claude Seo have an OpenSSF Scorecard?

Claude Seo has an OpenSSF Scorecard score of 7.1/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.

Is Claude Seo actively maintained?

Actively maintained. The repository was pushed to within the last 6 day(s).

What license does Claude Seo use?

Claude Seo ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Claude Seo's commits signed?

82% of the last 100 commits to Claude Seo are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.
