Compare Claude Skills
How does it stack up against its Agent Skills neighbours?
Pick any agent to compare →In detail: Claude Skills scores 27.5/100 (Grade D), ranked #380 of 385 tracked open-source AI agent projects, on evidence coverage D (1 of 5 independent signal types). The public evidence: no package-provenance attestation found; no OSSF Scorecard result yet; 72% of recent commits are signed; last pushed 2026-10-21. Every point is earned from checkable signals — never paid placement. How scoring works →
How Claude Skills 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 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.
-
Source Partly signed
github.com/alirezarezvani/claude-skills, MIT, last pushed 2026-10-21. 72% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.
-
Review and release Not checked
No OpenSSF Scorecard result yet, so branch protection, code review and release signing are unverified.
-
Published packages None
No registry package. Claude Skills is used from its repository, so what you run is whatever you check out: pin a release tag or commit.

Verify this score yourself
Every build re-issues Claude Skills’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.

Quick Trust Read
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 D is separate — it grades how many independent signal types back the score (1 of 5), so a high score on thin evidence stays visible. Full methodology →

Maintain Claude Skills?
For maintainers
HVTrust scores Claude Skills 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.
