The Secret AI Prompt Tool Silicon Valley Engineers Are Using

Episode 57: Can simply "Vibe coding" with AI really replace the need for deep code context when building real applications? Nathan Lands (https://x.com/NathanLands) is joined by Eric Provencher (https://x.com/pvncher), founder of Repo Prompt and an XR engineer at Unity, to reveal the secret AI prompt tool quietly powering Silicon Valley’s top engineers. This episode dives deep into why the current trend of "Vibe coding" with tools like Cursor often falls apart for complex tasks — and how Repo Prompt closes the gap by letting you build effective, highly targeted context for AI coding. Eric breaks down the philosophy behind contextual prompting, gives a live demo, and shares how Repo Prompt’s unique features like the context builder and codemaps give power-users real control over LLMs like Gemini and Claude. Beyond coding, they discuss implications for the future of engineering, learning, and the evolution of dev tools in the age of AI.
