Agent Skills Shell Listed MIT

Is Han safe? Promising trust profile, but some evidence still deserves review.

OSSF Scorecard 5.9 / 10
Provenance None
Signed commits 24%
Last push 10d ago

In detail: Han scores 56.8/100 (Grade C), ranked #139 of 371 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 5.9/10; 24% of recent commits are signed; last pushed 2026-10-01. Every point is earned from checkable signals — never paid placement. How scoring works →

How Han could raise its score

Each line changes one public signal and recomputes with the live scoring function. The gains don't add up exactly, because the score is capped near the top.

Chain of custody

Scanners check what the code says. This traces who ships Han and whether that has changed: from the source repository, through how changes are reviewed and released, to the code you run. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities and, for skills, AST02 Supply Chain Compromise.

  1. Source Partly signed

    github.com/testdouble/han, MIT, last pushed 2026-10-01. 24% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

  2. Review and release Mixed

    OpenSSF Scorecard rates the repository's practices 5.9/10 (scanned Sep 27, 2026). The checks that decide who can get a change released:

    No registry package. Han is used from its repository, so what you run is whatever you check out: pin a release tag or commit.

Evidence behind this score

Coverage C: 2 of 5 independent evidence types found.

  • GitHub repository data
  • Package downloads (missing)
  • Supply-chain checks
  • Public actions (missing)
  • Community mentions (missing)

Verify this score yourself

Every build re-issues Han’s score as an Ed25519-signed credential, valid for 7 days. You can check it offline against HVTracker’s published key; if anyone changes a number after signing, verification fails.

What this score doesn’t check

It covers who ships the code, not what the code does. It doesn’t read the skill’s instructions for injected instructions, watch runtime behaviour, or find bugs nobody has disclosed yet. For that, run a content scanner before you install it, such as Cisco Skill Scanner.

Maintainer Checklist
Raise Scorecard signals Current OSSF Scorecard is 5.9/10. 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 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 →

Common questions about Han

Han 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 Han publish package provenance?
No published build provenance is currently detected for Han. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Han have an OpenSSF Scorecard?
Han has an OpenSSF Scorecard score of 5.9/10. 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 Han actively maintained?
Maintained. Last push was 10 days ago.
What license does Han use?
Han ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Han's commits signed?
24% of the last 100 commits to Han 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.

Maintain Han?

For maintainers

HVTrust scores Han 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.
