Maintainer Checklist

Raise Scorecard signals Current OSSF Scorecard is 6.4/10. Tighten the weakest checks to improve public safety evidence.

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 40 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 C 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 Stitch Skills

Stitch Skills 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 Stitch Skills publish package provenance?

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

Does Stitch Skills have an OpenSSF Scorecard?

Stitch Skills has an OpenSSF Scorecard score of 6.4/10. 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 Stitch Skills actively maintained?

Slowing down. Last push was 40 days ago — keep an eye on whether activity resumes.

What license does Stitch Skills use?

Stitch Skills ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Stitch Skills's commits signed?

38% of the last 100 commits to Stitch 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.
