Is ControlFlow safe? ControlFlow scores 55.0/100 (Grade C), ranked #395 of 1204 tracked open-source AI agent projects, on evidence coverage A (4 of 5 independent signal types). The public evidence: its packages ship with cryptographic provenance; OSSF Scorecard rates its supply-chain practices 4.1/10; 29% of recent commits are signed; last pushed 2025-08-22. Every point is earned from checkable signals — never paid placement. How scoring works →

Maintainer Checklist
Raise Scorecard signals Current OSSF Scorecard is 4.1/10. Tighten the weakest checks to improve public safety evidence.
Increase signed commits Raise the share of verified-signed commits to make maintainer identity and release history easier to trust.
Refresh maintenance signals The repo was last pushed 352 days ago. Fresh activity helps separate stable projects from stale ones.

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 A is separate — it grades how many independent signal types back the score (4 of 5), so a high score on thin evidence stays visible. Full methodology →

Is ControlFlow safe?

ControlFlow 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 ControlFlow publish package provenance?
Yes. ControlFlow's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does ControlFlow have an OpenSSF Scorecard?
ControlFlow has an OpenSSF Scorecard score of 4.1/10. 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 ControlFlow actively maintained?
Stale. The repository has not been pushed to in 352 days. Consider whether the project is still being maintained.
What license does ControlFlow use?
ControlFlow ships under Apache-2.0. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are ControlFlow's commits signed?
28% of the last 100 commits to ControlFlow 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 ControlFlow?

For maintainers

HVTrust scores ControlFlow 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.
