GitHub Unleashed: LLMs on Guard | Tim Warner
What happens when you don't just ask one LLM to check your work, but three, and then make them vote? In this episode of The Pluralsight Podcast, we sit down with Tim Warner, Principal Pluralsight Author, Microsoft MVP, and author of more than 200 Pluralsight courses, to talk about what it takes to stay current through three decades of tech disruption, and why gen AI is just the latest wave to ride rather than fear. Tim breaks down what technology and L&D leaders get wrong in the AI gold rush, why shadow AI is the new shadow IT, and how to pair training with guardrails and sandboxes your teams will actually use. Then Tim takes us inside GitHub for a live demo: a GitHub Actions workflow that hands agent and skill definitions to three different LLMs, which scan for prompt injection and other vulnerabilities, then vote on a verdict through a simple quorum mechanism. It's a practical look at defense in depth for AI-assisted development, explained in plain language.
