In Coding Agents

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 B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

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

Does Ouroboros (Agent OS) have an OpenSSF Scorecard?

Ouroboros (Agent OS) has an OpenSSF Scorecard score of 5.8/10. 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 Ouroboros (Agent OS) actively maintained?

Actively maintained. The repository was pushed to within the last 1 day(s).

What license does Ouroboros (Agent OS) use?
