Hackerbot-Claw Grows, Xygeni Tag Poisoning, GitHub Search HA, Windows SID Failures, and AI Skills Supply Chain

This episode of Ship It Weekly is about the places where convenience quietly turns into trust.

Brian revisits the Trivy story by zooming out to the bigger hackerbot-claw GitHub Actions campaign, then gets into the Xygeni tag-poisoning compromise, GitHub’s search high availability rebuild for GitHub Enterprise Server, Windows Server 2025 surfacing duplicate SID problems in cloned images, and the agent-skills ecosystem replaying package supply chain history. Plus: a quick lightning round on GitHub pausing self-hosted runner minimum-version enforcement and March secret scanning updates.
