Your School AI Rules

Different schools have different rules about AI.

A Short History: From Expert Systems to Transformers

AI did not start in 2022. It has decades of wrong turns and breakthroughs. Knowing the history helps you spot hype from real progress.

Few-Shot Prompting: Teach by Example

Instead of describing what you want, show the AI two or three examples. Few-shot prompting is often the fastest way to get consistent output.

Your First Git Commit, Explained

Git is a time machine for your code. Before we ship anything, let's learn the three commands that matter and what they actually do under the hood.

Your First Capstone — Ship a Small Project

Bring it all together. Pick one of three starter projects, plan it, build it with AI, and deploy it. You are now a builder who ships.

Your First Agent: A Walkthrough of What It Does

Follow a real agent run step by step — from prompt to result — and see exactly what happens inside. No code yet, just the anatomy of a successful task.

Tools an Agent Might Have: Filesystem, Browser, Code

Agents are only as useful as their tools. Tour the big three — filesystem, browser, code execution — plus the emerging MCP ecosystem, with examples of what each unlocks.

Builder Capstone: Ship a Short Creative Piece

Your first end-to-end AI-assisted creative project. Plan it, make it, and reflect on what surprised you. Small scope, real output.

Consumer Apps vs. API — What You're Actually Paying For

Claude.ai and the Anthropic API both run Claude. So why do they cost different amounts? Pull apart the two doors into the same model.

Claude vs. ChatGPT vs. Gemini — Side-by-Side

All three claim to be the best. Pick tasks you actually care about, run the same prompt across all three, and you'll build your own benchmark.

Browser Extensions — Claude for Chrome, Perplexity, and Friends

AI in your browser turns every webpage into something you can interrogate. Learn which extension to install, and why that access needs trust.

Transformers Under the Hood

Attention, positional encoding, residual streams. A walk through the architecture that powers every frontier language model today.

Open vs. Closed Models: Philosophy and Strategy

Open-source AI is both a technical movement and a political one. Understand the arguments so you can pick a stack and defend it.

The Three Ingredients: Data, Compute, Algorithms (Capstone)

Every AI breakthrough of the past decade rests on three interacting ingredients. Synthesize everything you have learned into one working model.

Anthropic's Prompt Engineering Patterns

Anthropic publishes detailed prompt engineering guidance. Master the core patterns — Be Direct, Let Claude Think, and Chain Complex Prompts — to write production-grade prompts.

Meta-Prompting: AI That Writes AI Prompts

Use an AI to write, optimize, and debug your prompts. Meta-prompting is how top teams ship production prompts faster than humans alone could write them.

The EU AI Act: The Global Floor, Whether You Like It or Not

The EU AI Act is the most sweeping AI law in the world. It will set the compliance floor for anyone who ships globally. Here is the architecture, the timeline, and what it gets right and wrong.

Labor and AI: What the Data Actually Says

Most predictions about AI and jobs are either panic or dismissal. Here is what the best evidence through 2025 actually shows — including what is overstated.

Responsible Scaling Policies Explained

RSPs are the frontier labs' self-imposed rules for what capability thresholds trigger which safeguards. Here is what they commit to, what they hedge on, and what the enforcement problem is.

Installing and Using Claude Code CLI

Claude Code is Anthropic's terminal-native coding agent. Let's install it, wire it to a project, and use the features most engineers miss on day one.

Test-Driven AI Development

TDD was already the gold standard. Paired with an agent, it becomes the tightest feedback loop in software. Here's the full workflow and the pitfalls.

AI-Assisted Code Review Workflows (for Teams)

Code review is the highest-leverage touchpoint in a team. Automating the noise with AI frees humans to focus on the irreducibly human parts. Let's design the workflow.

Agentic Shell Workflows — Claude Code Sub-Agents in Practice

Sub-agents turn Claude Code from a coding assistant into a small engineering team that works in parallel. Let's build a real sub-agent workflow end to end.

Deploy Pipelines With AI in the Loop

AI belongs in CI/CD too. From PR previews to rollback judgment calls, agents can operate inside your pipeline safely — if you scope them right.

What A Business Actually Is

Forget the TikTok hustle videos. A business is a machine that turns work into money, and the machine has parts you can name.

Reading A P&L Without Falling Asleep

The profit and loss statement is a business's health check. Here's how to read one in ten minutes and spot trouble in thirty seconds. The three P&L numbers that tell you 90% of the story Gross margin % — tells you the fundamental health of the business model Operating expense growth vs.
