Three Checkpoints, One Progression

Ch3 L04 Hello World  -->  basics/ Modules 1-4  (one-shot problem solving)
Ch3 L05 CLAUDE.md    -->  basics/ Modules 5-8  (systematic problem solving)
Ch3 L09 Subagents    -->  skills/ Modules 1-8  (reusable problem solving)

Pack	Modules	What You Learn	When to Start	Exercises
basics/	M1-M4	Solve one-shot problems with natural language	After L04 (Hello World)	12 exercises
basics/	M5-M8	Systematic problem solving with persistent context	After L05 (CLAUDE.md)	9 exercises + 3 capstones
skills/	M1-M8	Turn solutions into reusable skills and patterns	After L09 (Subagents)	21 exercises + 3 capstones

basics/ teaches you to describe problems clearly so Claude can solve them. skills/ teaches you to package solutions so they work every time.

Start Here (Recommended Minimum Path)

If you're short on time, do these 9 exercises from basics/:

1. Module 1 — File Organization (exercises 1.1, 1.2, 1.3)
2. Module 2 — Research & Synthesis (exercises 2.1, 2.2, 2.3)
3. Module 3 — Data Wrangling (exercises 3.1, 3.2, 3.3)

These build the core skill: turning messy real-world problems into clear specifications.

# Read INSTRUCTIONS.md and start solving

With Cowork (Desktop App)

1. Open the Claude Desktop app and switch to the Cowork tab
2. Point Cowork at the exercise folder
3. Read INSTRUCTIONS.md and describe your task to Claude

With Claude Code (Terminal)

1. Open your terminal and navigate to the exercise folder
2. Run claude
3. Read INSTRUCTIONS.md and start working

What's Inside

basics/ — Problem Solving (8 modules)

Organize files, research topics, wrangle data, create documents, automate workflows, solve problems, and verify AI output. All materials pre-made — download and start.

See basics/README.md for the full exercise list.

skills/ — Reusable Problem Solving (8 modules)

Understand skills, build your first skills, add examples and references, test and iterate, compose skill pipelines, and build production-ready workflows.

See skills/README.md for the full exercise list.

Problem-Solving Framework

Use this for every exercise:

1. Define — What exactly am I trying to accomplish?
2. Gather — What files/data does Claude need?
3. Specify — Describe the desired outcome, constraints, and format
4. Execute — Run it with Claude Code or Cowork
5. Verify — Does the output match what I asked for?
6. Iterate — What would I change? Run it again.
7. Reflect — What did I learn about specifying problems clearly?
