In Agent Frameworks

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 →

Is fast-agent safe?

fast-agent 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 fast-agent publish package provenance?

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

Does fast-agent have an OpenSSF Scorecard?

fast-agent has an OpenSSF Scorecard score of 5.9/10. 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 fast-agent actively maintained?

Actively maintained. The repository was pushed to within the last 1 day(s).

What license does fast-agent use?

fast-agent ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are fast-agent's commits signed?

60% of the last 100 commits to fast-agent 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 fast-agent?

For maintainers

HVTrust scores fast-agent 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.
