Is Sepia safe? Sepia scores 24.0/100 (Grade D), ranked #327 of 351 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; 25% of recent commits are signed; last pushed 2026-09-08. Every point is earned from checkable signals — never paid placement. How scoring works →

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 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 →

Is Sepia safe?

Public trust evidence for Sepia 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 Sepia publish package provenance?
No published build provenance is currently detected for Sepia. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does Sepia have an OpenSSF Scorecard?
No OpenSSF Scorecard data is currently published for Sepia. Maintainers can enable the Scorecard GitHub Action to get a public score; without it, automated supply-chain hygiene is harder for outsiders to verify.
Is Sepia actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Sepia use?
Sepia ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Sepia's commits signed?
25% of the last 100 commits to Sepia 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 Sepia?

For maintainers

HVTrust scores Sepia 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.
