Maintainer Checklist

Raise Scorecard signals Current OSSF Scorecard is 3.4/10. Tighten the weakest checks to improve public safety evidence.

Publish provenance Add package provenance or release attestations so users can verify where shipped artifacts came from.

Refresh maintenance signals The repo was last pushed 32 days ago. Fresh activity helps separate stable projects from stale ones.

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 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 Crabtalk

Public trust evidence for Crabtalk 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 Crabtalk publish package provenance?

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

Does Crabtalk have an OpenSSF Scorecard?

Crabtalk has an OpenSSF Scorecard score of 3.4/10. 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 Crabtalk actively maintained?

Slowing down. Last push was 32 days ago — keep an eye on whether activity resumes.

What license does Crabtalk use?

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

Are Crabtalk's commits signed?

100% of the last 100 commits to Crabtalk 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.
