NVIDIA’s new open-source scanner catches 64 vulnerability patterns in AI agent skills—26.1% of which are vulnerable. Integrate it into your CI/CD pipeline.
An AI agent racked up massive cloud bills scanning DN42. No cost controls = bankruptcy risk.
LLMs with 200K context windows still hallucinate on page 100. Commenters report degraded performance and false details. For production systems, chunking + RAG beats raw context every time.
Flutter & Dart just shipped official Agent Skills repos. One npx command stops AI from generating deprecated 2022 patterns like MediaQuery.orientationOf.
