Is Open Operator safe? Open Operator scores 28.1/100 (Grade D), ranked #744 of 1204 tracked open-source AI agent projects, on evidence coverage B (3 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 2.4/10; 23% of recent commits are signed; last pushed 2026-05-04. Every point is earned from checkable signals — never paid placement. How scoring works →

Maintainer Checklist
Declare an open license Publish a clear OSI-approved license so usage and maintenance terms are independently verifiable.
Raise Scorecard signals Current OSSF Scorecard is 2.4/10. 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.

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 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 →

Is Open Operator safe?

Public trust evidence for Open Operator 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 Open Operator publish package provenance?
No published build provenance is currently detected for Open Operator. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Open Operator have an OpenSSF Scorecard?
Open Operator has an OpenSSF Scorecard score of 2.4/10. 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 Open Operator actively maintained?
Slowing down. Last push was 97 days ago — keep an eye on whether activity resumes.
What license does Open Operator use?
Open Operator ships under no SPDX license detected. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Open Operator's commits signed?
23% of the last 100 commits to Open Operator 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.

For maintainers

HVTrust scores Open Operator 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.
