In detail: Evolver scores 55.4/100 (Grade C), ranked #162 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 3.2/10; 16% of recent commits are signed; no published advisory affects its latest release (@evomap/evolver); last pushed 2026-09-30. Every point is earned from checkable signals — never paid placement. How scoring works →

How Evolver 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 Evolver 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/EvoMap/evolver, GPL-3.0, last pushed 2026-09-30. 16% of the last 100 commits carry a verified signature; the rest can't be tied to a verified identity.

  2. Review and release Weak

    OpenSSF Scorecard rates the repository's practices 3.2/10 (scanned Oct 9, 2026). The checks that decide who can get a change released:

  3. Published packages Linked, not attested

    • npm @evomap/evolver 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: @evomap/evolver 2.0.42. No published advisory affects it (OSV, checked 2026-10-10).

  • Public actions (missing)

Verify this score yourself

Every build re-issues Evolver’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 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 Evolver

Evolver 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 Evolver publish package provenance?
No published build provenance is currently detected for Evolver. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Evolver have an OpenSSF Scorecard?
Evolver 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 Evolver actively maintained?
Maintained. Last push was 10 days ago.
What license does Evolver use?
Evolver ships under GPL-3.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Evolver's commits signed?
16% of the last 100 commits to Evolver 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 Evolver?

For maintainers

HVTrust scores Evolver 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.
