Chain of custody

Scanners check what the code says. This traces who ships Callstackincubator Agent 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 Signed

github.com/callstackincubator/agent-skills, MIT, last pushed 2026-10-08. 81% of the last 100 commits carry a verified signature, so changes trace to a verified account.

Verify this score yourself

Every build re-issues Callstackincubator Agent 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.

Signed credential (JSON) How to verify

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.

In Agent Skills

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 Callstackincubator Agent Skills

Public trust evidence for Callstackincubator Agent Skills 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 Callstackincubator Agent Skills publish package provenance?

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

Does Callstackincubator Agent Skills have an OpenSSF Scorecard?

Callstackincubator Agent Skills has an OpenSSF Scorecard score of 4.4/10. 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 Callstackincubator Agent Skills actively maintained?

Slowing down. Last push was 33 days ago — keep an eye on whether activity resumes.

What license does Callstackincubator Agent Skills use?

Callstackincubator Agent Skills ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are Callstackincubator Agent Skills's commits signed?

81% of the last 100 commits to Callstackincubator Agent Skills 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.
