Is Agent-S safe? Agent-S scores 47.2/100 (Grade D), ranked #505 of 1308 tracked open-source AI agent projects, on evidence coverage C (2 of 5 independent signal types). The public evidence: no package-provenance attestation found; OSSF Scorecard rates its supply-chain practices 3.7/10; recent commits are unsigned; last pushed 2026-08-01. Every point is earned from checkable signals — never paid placement. How scoring works →

Maintainer Checklist

Raise Scorecard signals Current OSSF Scorecard is 3.7/10. 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 Browser & Computer Use

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 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 Agent-S safe?

Public trust evidence for Agent-S 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 Agent-S publish package provenance?

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

Does Agent-S have an OpenSSF Scorecard?

Agent-S has an OpenSSF Scorecard score of 3.7/10. 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 Agent-S actively maintained?

Maintained. Last push was 18 days ago.

What license does Agent-S use?

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

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.

Maintain Agent-S?

For maintainers

HVTrust scores Agent-S 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.
