In detail: Skillgrade scores 54.5/100 (Grade C), ranked #180 of 371 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 4.1/10; 22% of recent commits are signed; no published advisory affects its latest release (skillgrade); last pushed 2026-10-11. Every point is earned from checkable signals — never paid placement. How scoring works →

How Skillgrade 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 Skillgrade and whether that has changed: from the source repository, through how changes are reviewed and released, to the package you install. These are the checks for OWASP ASI04 Agentic Supply Chain Vulnerabilities and, for skills, AST02 Supply Chain Compromise.

  1. Source Partly signed

    github.com/mgechev/skillgrade, MIT, last pushed 2026-10-11. 22% 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 4.1/10 (scanned Oct 10, 2026). The checks that decide who can get a change released:

  3. Published packages Linked, not attested

    • npm skillgrade Source link points back to this repo No build attestation

    Without a build attestation, nothing proves the published files were built from this repository.

  4. What you install today No known advisories

    Latest release checked: skillgrade 0.3.1. No published advisory affects it (OSV, checked 2026-10-11).

Evidence behind this score

Coverage B: 3 of 5 independent evidence types found.

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

Verify this score yourself

Every build re-issues Skillgrade’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.

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 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 →

Common questions about Skillgrade

Public trust evidence for Skillgrade 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 Skillgrade publish package provenance?
No published build provenance is currently detected for Skillgrade. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Skillgrade have an OpenSSF Scorecard?
Skillgrade has an OpenSSF Scorecard score of 4.1/10. 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 Skillgrade actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Skillgrade use?
Skillgrade ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Skillgrade's commits signed?
22% of the last 100 commits to Skillgrade 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 Skillgrade?

For maintainers

HVTrust scores Skillgrade 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.
