Publish provenance Add package provenance or release attestations so users can verify where shipped artifacts came from.

Increase signed commits Raise the share of verified-signed commits to make maintainer identity and release history easier to trust.

Refresh maintenance signals The repo was last pushed 33 days ago. Fresh activity helps separate stable projects from stale ones.

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 D 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 Jakub Krehel Skills

Public trust evidence for Jakub Krehel Skills is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.

Does Jakub Krehel Skills publish package provenance?

Does Jakub Krehel Skills have an OpenSSF Scorecard?

Jakub Krehel Skills has an OpenSSF Scorecard score of 2.6/10. 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 Jakub Krehel Skills actively maintained?

Slowing down. Last push was 33 days ago — keep an eye on whether activity resumes.

What license does Jakub Krehel Skills use?

Jakub Krehel Skills ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Jakub Krehel Skills's commits signed?

27% of the last 100 commits to Jakub Krehel Skills 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.
