Stanford CS146S Deep Dive (5): From Prototype to Production — The Full AI App Lifecycle

Tue, 24 Feb 2026 09:00:00 +0800

This is Part 5 (the finale) of the “Stanford Vibe Coding Course Deep Dive” series. See the series navigation at the bottom.

“Build an app with one prompt” — that’s probably the most eye-catching selling point of Vibe Coding.

The Week 8 guest was Gaspar Garcia, Head of AI Research at Vercel. He demonstrated live how AI can generate a complete web application from a single prompt — frontend, backend, database, deployment — all in one shot.

Stanford CS146S Deep Dive (4): Secure Vibe Coding — AI Code Security Guide

Tue, 24 Feb 2026 08:30:00 +0800

This is Part 4 of the “Stanford Vibe Coding Course Deep Dive” series. See the series navigation at the end of this article.

Weeks 6 and 7 of CS146S are the most spine-chilling weeks of the entire course.

Week 6 covers security: when AI writes your code, who ensures it’s not vulnerable to attacks? Even scarier — what happens when the AI itself becomes the attack surface?

Week 7 covers review: how much can we actually trust AI-generated code?

Stanford CS146S Deep Dive (3): Agent Manager — Best Practices for Human-AI Collaboration

Tue, 24 Feb 2026 08:00:00 +0800

This is Part 3 of the “Stanford Vibe Coding Course Deep Dive” series. See the series navigation at the end of this article.

The title of CS146S Week 4 is “Coding Agent Patterns,” but what it really teaches is an entirely new professional skill: Agent Manager.

What is an Agent Manager? Someone who doesn’t write code directly but directs AI Agents to write code. It might sound like being a “hands-off boss,” but in reality, this may be one of the hardest and most valuable skills of the AI coding era.

Context Engineering: The Most Underrated Core Skill in AI Programming (Stanford CS146S Deep Dive)

This is Part 2 of the “Stanford Vibe Coding Course Deep Dive” series. See the series navigation at the end of this article.

If I had to pick just one week from the entire 10-week CS146S curriculum for a deep dive, I would choose Week 3 without hesitation.

Not because it is the flashiest – that would be Week 8’s “build an app with one sentence.” Not because it is the most hardcore – that would be Week 6’s security deep dive. It is because what Week 3 covers directly determines the ceiling of your AI programming capability.

Stanford CS146S Deep Dive (Part 1): How Vibe Coding Became a Real Academic Discipline

Tue, 24 Feb 2026 07:00:00 +0800

From Andrej Karpathy coining Vibe Coding in a February 2025 tweet to Stanford officially launching CS146S that same fall — less than 8 months. A social media buzzword entering a top university’s curriculum this fast is almost unprecedented in the history of computer science.

This is not some “learn to code with ChatGPT” fluff course. CS146S covers the full software engineering lifecycle — from LLM fundamentals to Agent architectures, from context engineering to security, from automated builds to production operations. Its guest speaker list reads like an AI coding hall of fame: the creator of Claude Code, Vercel’s Head of AI Research, Semgrep’s CEO, an a16z general partner…
