Maintainer Checklist
Raise Scorecard signalsCurrent OSSF Scorecard is 5.6/10. Tighten the weakest checks to improve public safety evidence.
Publish provenanceAdd package provenance or release attestations so users can verify where shipped artifacts came from.
Increase signed commitsRaise the share of verified-signed commits to make maintainer identity and release history easier to trust.
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 UFO safe?
UFO 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 UFO publish package provenance?
No published build provenance is currently detected for UFO. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does UFO have an OpenSSF Scorecard?
UFO has an OpenSSF Scorecard score of 5.6/10. 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 UFO actively maintained?
Actively maintained. The repository was pushed to within the last 3 day(s).
What license does UFO use?
UFO ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are UFO's commits signed?
35% of the last 100 commits to UFO 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.
These runtime-trust fields — detected from public repo docs and manifests — contribute a bounded adjustment to this project's HVTrust score alongside supply-chain evidence.

How this surface has changed
Detected changes to UFO's runtime surface and supply-chain posture, from daily public-signal snapshots. A change here means our detectors see something different — a genuinely changed capability, or better evidence of an existing one.
Runtime surface grew — new detected provider dependencies: Anthropic, Azure OpenAI, Google Gemini, OpenAI

Maintain UFO?
HVTrust scores UFO from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
