Every point is earned from checkable signals — never paid placement. How scoring works →

How Claude Skills Marketplace 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 Claude Skills Marketplace 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 Signed

    github.com/mhattingpete/claude-skills-marketplace, Apache-2.0, last pushed 2026-07-25. 96% of the last 100 commits carry a verified signature, so changes trace to a verified account.

  2. Review and release Weak

    OpenSSF Scorecard rates the repository's practices 3.2/10 (scanned Sep 29, 2026). The checks that decide who can get a change released:

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 Claude Skills Marketplace’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 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 →

Common questions about Claude Skills Marketplace

Public trust evidence for Claude Skills Marketplace 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 Claude Skills Marketplace publish package provenance?
No published build provenance is currently detected for Claude Skills Marketplace. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Claude Skills Marketplace have an OpenSSF Scorecard?
Claude Skills Marketplace has an OpenSSF Scorecard score of 3.2/10. 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 Claude Skills Marketplace actively maintained?
Slowing down. Last push was 78 days ago — keep an eye on whether activity resumes.
What license does Claude Skills Marketplace use?
Claude Skills Marketplace ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Claude Skills Marketplace's commits signed?
95% of the last 100 commits to Claude Skills Marketplace 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 Claude Skills Marketplace?

For maintainers
