Raise Scorecard signals Current OSSF Scorecard is 6.2/10. 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.

In Security & Guardrails

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 →

Is SkillSpector safe?

SkillSpector 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 SkillSpector publish package provenance?
No published build provenance is currently detected for SkillSpector. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does SkillSpector have an OpenSSF Scorecard?
SkillSpector has an OpenSSF Scorecard score of 6.2/10. 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 SkillSpector actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does SkillSpector use?
SkillSpector ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are SkillSpector's commits signed?
39% of the last 100 commits to SkillSpector 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.
