How Antigravity For Claude Code 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 Antigravity For Claude Code 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/yuting0624/antigravity-for-claude-code, MIT, last pushed 2026-10-05. 78% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

  2. Review and release Strong

    OpenSSF Scorecard rates the repository's practices 7.2/10 (scanned Oct 8, 2026). The checks that decide who can get a change released:

  3. Published packages None

    No registry package. Antigravity For Claude Code 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 Antigravity For Claude Code’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 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 Antigravity For Claude Code

Antigravity For Claude Code 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 Antigravity For Claude Code publish package provenance?
No published build provenance is currently detected for Antigravity For Claude Code. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Antigravity For Claude Code have an OpenSSF Scorecard?
Antigravity For Claude Code has an OpenSSF Scorecard score of 7.2/10. 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 Antigravity For Claude Code actively maintained?
Actively maintained. The repository was pushed to within the last 6 day(s).
What license does Antigravity For Claude Code use?
Antigravity For Claude Code ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Antigravity For Claude Code's commits signed?
78% of the last 100 commits to Antigravity For Claude Code 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 Antigravity For Claude Code?

For maintainers

HVTrust scores Antigravity For Claude Code 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.
